stop closing over the method metaobject

[gitmo/Moose.git] / Changes.Class-MOP

After 1.12, Class::MOP was merged into the Moose distribution, and is no
longer released separately.

1.12 Mon, Jan 3, 2011

  * Remove usage of undocumented Package::Stash APIs from the tests. This
    prevents the tests from failing on Package::Stash >= 0.18.

1.11 Sun, Oct 31, 2010

  [ENHANCEMENTS]

  * Replace use of Test::Exception with Test::Fatal. (Karen Etheridge and Dave
    Rolsky)

1.10 Mon, Oct 18, 2010

  [BUG FIXES]

  * Lots of fixes for edge cases with anon classes. (doy)

1.09 Tue, Oct 5, 2010

  [ENHANCEMENTS]

  * It's now possible to tell Class::MOP::Class->create and the metaclass
    pragma to not install a 'meta' method into classes they manipulate,
    or to install one under a different name. (doy)

  * Reinitializing a metaclass no longer removes the existing method and
    attribute objects (it instead fixes them so they are correct for the
    reinitialized metaclass). (doy)

  * All 'meta' methods created by Class::MOP are now of the class
    Class::MOP::Method::Meta. This is overridable at the metaclass layer. (doy)

  [OTHER]

  * Use get_or_add_package_symbol when we intend for it to autovivify, in
    preparation for changes in Package::Stash. (doy)

  * We now use Module::Install::AuthorRequires to force authors to run all
    tests, just like we do for Moose. (sartak)

1.08 Mon, Sep 13, 2010

  [BUG FIXES]

  * The get_method_list and _get_local_methods methods blew up in the face
    of subroutine stubs. (Goro Fuji)  

1.07 Tue, Aug 25, 2010

  [BUG FIXES]

  * Fix a mysterious error reported by Piers Cawley. The error showed up as
    "Can't use an undefined value as a symbol reference at
    /usr/local/lib/perl/5.10.1/Class/MOP/Mixin/HasMethods.pm line 167." (Dave
    Rolsky)

1.06 Sun, Aug 23, 2010

  [BUG FIXES]

  * Version 1.05 no longer reported constants as methods, except with Perl
    5.8.x, and doing so in 5.8.x caused test failures. Constants are now
    _expected_ to be reported as methods, and we explicitly test this. (Dave
    Rolsky)

1.05 Sun, Aug 22, 2010

  [ENHANCEMENTS]

  * Refactorings and improvements to how defaults are handled, particularly
    for inlined code (doy).

  * Optimizations that should help speed up compilation time (Dave Rolsky).

1.04 Tue, Jul 25, 2010

  [ENHANCEMENTS]

  * Class::MOP::Deprecated now uses Package::DeprecationManager
    internally. Deprecation warnings are now only issued once for each calling
    package, which cuts down on noise. When importing Class::MOP::Deprecated,
    the request API version should now be passed in the "-api_version"
    flag. However, the old "-compatible" flag will continue to work. (Dave
    Rolsky)

1.03 Sat, Jun 5, 2010

  [ENHANCEMENTS]

  * Make CMOP::Package a thin wrapper around Package::Stash (doy).

1.02 Thu, May 20, 2010

  [API CHANGES]

  * Packages and modules no longer have methods - this functionality was
    moved back up into Class::MOP::Class (doy).

  [ENHANCEMENTS]

  * Metaclass incompatibility checking now checks all metaclass types. (doy)

  * Class::MOP can now do simple metaclass incompatibility fixing: if your
    class's metaclass is a subclass of your parent class's metaclass, it will
    just use the parent class's metaclass directly. (doy)

1.01 Thu, May 6, 2010

  [NEW FEATURES]

  * is_class_loaded, load_class and load_first_existing_class now allow
    specifying a minimum required version (Florian Ragwitz).

  [BUG FIXES]

  * The __INSTANCE__ parameter to Class::MOP::Class::new_object now enforces
    that the passed in reference is blessed into the correct class (by dying if
    it's not) (doy, jhallock).

1.00 Thu, Mar 25, 2010

  [GRRR< FUCKING STEVAN@]

  * Re-release 0.99 as 1.00.

0.99 Thu, Mar 25, 2010

  [DOCUMENTATION]

  * Fix typo in Class::MOP::Attribute (Franck Cuny).

0.98 Mon, Jan 18, 2010

  [ENHANCEMENTS]

  * Added Class::MOP::Class->rebless_instance_back, which does the inverse of
    rebless_instance (doy, rafl).

0.97_01 Mon, Jan 4, 2010

  [ENHANCEMENTS]

  * Internal refactorings to move shared behavior into new "mixin" classes. This
    made adding some new features to Moose much easier. (Dave Rolsky)

0.97 Fri, Dec 18, 2009
    * No code changes, just packaging fixes to make this distro installable.

0.96 Fri, Dec 18, 2009
    * tests
      - Fixed t/082_get_code_info.t so it passes with bleadperl. (Dave Rolsky)
      - Add XS & C files to no tabs check (Dave Rolsky)
      - Convert all tests to done_testing. (Florian Ragwitz)

0.95 Wed, Nov 19, 2009
    * Class::MOP
      - Make is_class_loaded without any arguments fail loudly
        (Florian Ragwitz).
      - Make load_class throw more standard error messages when loading single
        modules (nothingmuch).

    * Class::MOP::Package
      - Stop add_method from behaving differently under the debugger
        (Florian Ragwitz).

    * Class::MOP::Class
    * Class::MOP::Package
      - Any method which takes a method name as an argument now allows names
        which are false (like "0"), but the name must be defined and not be an
        empty string. (Dave Rolsky)

    * Class::MOP::Class
      - Deprecated get_attribute_map as a public method. You can use a
        combination of get_attribute_list and get_attribute instead. (Dave
        Rolsky)

0.94 Tue, Sep 22, 2009
    * Class::MOP::Attribute
      - Introduce set_raw_value and get_raw_value, side effect free variants
        of {get,set}_value. These don't do anything useful in Class::MOP but
        have different behavior that set_value and get_value for Moose
        attributes. (nothingmuch)

0.93 Tue, Sep 15, 2009
    * Class::MOP
      - The load_class function just returns true, since it's return value was
        confusing (either a metaclass object or a class name). It either loads
        a class or dies trying. In the future, this may change to not return
        anything, since there's no point in checking its return
        value. Addresses RT #45883. (Dave Rolsky)

    * Class::MOP::Class::Trait::Immutable
      - When throwing an error because of an immutable method, include that
        method's name. Addresses RT #49680. (Shawn M Moore)

    * Class::MOP::Package
      - Adding the same sub reference to multiple packages failed to update
        the method map properly. RT #48985. Reported by Paul Mooney. (Dave
        Rolsky)
      - The get_method_map method is now private (and called as
        _full_method_map or _method_map). The public version is available as a
        deprecated method. (Dave Rolsky)

0.92_01 Thu, Sep 10, 2009
    * Class::MOP::Package
      - Backwards compatibility tweaks to XS for 5.8.1. (Goro Fuji)

    * Class::MOP
      - Make sure XS code handles magical scalars correctly. (Goro Fuji)

    * Class::MOP::Class
      - Documented the immutable_options method, which is useful if you need
        to make a class mutable temporarily, and then nede to restore
        immutability. (Dave Rolsky)

    * Many modules
      - Deprecated features have been moved to their own module,
        Class::MOP::Deprecated, for easier deprecation management. (Goro Fuji)

0.92 Thu Aug 13, 2009
    * Class::MOP::Class
    * Class::MOP::Package
      - Move get_method_map and its various scaffolding into Package. (hdp)

    * Class::MOP::Method
      - Allow Class::MOP::Method->wrap to take a Class::MOP::Method object as
        the first argument, rather than just a coderef. (doy)

    * Class::MOP::Attribute
    * Class::MOP::Class
      - Allow attribute names to be false (while still requiring them to be
        defined). (rafl)

0.91 Wed Jul 29, 2009
    * Class::MOP::Method::Wrapped
      - Fixing variable usage issues with the patch from previous
        version, not properly using lexicals in the for
        loops. (stevan)

0.90 Tue Jul 21, 2009
    Japan Perl Association has sponsored Goro Fuji to improve startup
    performance of Class::MOP and Moose. These enhancements may break
    backwards compatibility if you're doing (or using) complex
    metaprogramming, so, as always, test your code!
    http://blog.perlassociation.org/2009/07/jpa-sponsors-moose-class-mop-work.html

    * Class::MOP::Class
    * XS
      - Anonymous classes were not completely destroyed when they went
        out of scope, leading to a memory leak. RT #47480. (Goro
        Fuji).

    * Class::MOP::Class
      - The get_method, has_method, and add_method methods no longer
        use get_method_map. Method objects are instantiated
        lazily. This significantly improves Class::MOP's load
        time. (Goro Fuji)

    * All classes
      - Inline fewer metaclass-level constructors since the ones we
        have are perfectly fine. This reduces the number of string
        evals. (Goro Fuji)

    * Class::MOP::Method::Wrapped
      - If a method modifier set $_, this caused the modifier to blow
        up, because of some weird internals. (Jeremy Stashewsky)

0.89 Fri Jul 3, 2009
    * Class::MOP::Class
    * Class::MOP::Class::Immutable::Trait
      - Made the Trait act like a role with a bunch of "around"
        modifiers, rather than sticking it in the inheritance
        hierarchy. This fixes various problems that caused with
        metaclass compatibility, which broke Fey::ORM.

    * Class::MOP::Method
      - Allow a blessed code reference as the method body. Fixes a
        problem interaction with MooseX::Types. (ash)

    * Class::MOP::Instance
      - add inline version of rebless_instance_structure. (doy)
      - change inline_slot_access to use single quotes (gphat)

0.88 Tue, Jun 23, 2009
    * Class::MOP::Class
      - Moved the __INSTANCE__ parameter to _construct_instance from
        Moose to here. (doy)
      - Fixed some issues involving metaclasses of metaclasses and
        immutability. (doy)

0.87 Sun, Jun 21, 2009
    * Various
      - Made sure to always local-ize $@ and $SIG{__DIE__} before
        calling an eval. Fixes RT #45973.

    * Class::MOP::Class
      - Synced docs about immutability with the current reality (which
        changed back in 0.82_01)
      - Removed the immutable_transformer method, which had been
        returning undef since 0.82_01 anyway.

    * Tests
      - Got rid of tests which needed Moose and improved testing of
        constructor/destructor inlining warnings. Fixes RT #47119.

0.86 Tue, Jun 16, 2009
    * Class::MOP::Class
      - If you redefined a subroutine at runtime and then wrapped it
        with a method modifier, the modifier could in some cases wrap
        the original version of the subroutine. Fixes RT #46957.

    * Class::MOP::Class
      - make_immutable issues a warning instead of overriding an
        existing DESTROY method (Dylan William Hardison). Fixes RT
        #46854.

0.85 Sat, Jun 6, 2009
    * Class::MOP::Attribute
      - Allow default values to be Class::MOP::Methods.  (Florian
        Ragwitz)
      - Test the above. (Rhesa Rozendaal)
      - Tweak original commit so the intent matches the accepted
        behavior (Nicholas Perez)

    * Class::MOP
      - Localize $SIG{__DIE__} inside _try_load_one_class (Sartak)

    * Class::MOP::Class
      - Add direct_subclasses method (Sartak)
        - Tests for subclasses and direct_subclasses (Sartak)
      - subname is no longer used unconditionally in add_method, but
        only if the code reference's name is '__ANON__' (nothingmuch)
      - Add a hook for _superclasses_updated (Sartak)

    * Class::MOP::Method
      - Remove long, old warning about possibly outdated modules
        (Sartak)

0.84 Tue, May 12, 2009
    * Makefile.PL
      - Depend on Text::Exception 0.27 to avoid failing tests ond old
        versions (rafl)

    * Class::MOP
      - Made is_class_loaded a little stricter. It was reporting that
        a class was loaded if it merely had an @ISA variable in its
        stash. Now it checks that the @ISA var has elements in it.
      - Deprecate in_global_destruction and subname re-exporting
        (perigrin & Sartak)

    * Class::MOP::Class
      - Explicitly use Devel::GlobalDestruction and Sub::Name
        (perigrin)

    * Class::MOP::Package
      - Disable prototype mismatch warnings for add_package_symbol.
        (Florian Ragwitz)
    * Tests
      - Add test for finding methods from $meta->name->meta before immutable,
        (t0m)

0.83 Mon, April 27, 2009
    * Class::MOP::Class
      - Fix segfault when calling get_method_map on a metaclass for an empty
        package (doy)

0.82_02 Fri, April 24, 2009
    * Class::MOP::Method::Inlined
      - Don't inline if the expected method is not defined at all (happens with
        e.g. Moose::Object::_new is the expected method due to an overridden
        name)
    * Tests
      - Some tests were trying to load Class::MOP::Immutable, which
        was removed in 0.82_01.

0.82_01 Thu, April 23, 2009
    * Class::MOP::Immutable (and others)
      - Refactor the immutability system to use a pre-defined class
        for the immutable metaclass of Class::MOP::Class::Immutable::$class
      - Rather than generating methods into this class every time, use
        a Trait (basic mixin) to supply the cached methods
      - Remove the hack that returns the mutable metaclass for
        metacircularity in order to provide consistent meta-metaclasses
        for the Moose compatibility handling code
        (mst broke it, nothingmuch fixed it)

0.82 Mon, April 20, 2009
    * Various
      - The deprecation wrappers for some renamed methods were not
        passing arguments to the new method. (nothingmuch)

    * Class::MOP::Immutable
      - Warn during immutablization if the local class provides its own
        constructor, to parallel the warning in Moose when a superclass
        provides its own constructor (doy)

0.81 Tue, April 7, 2009
    * Class::MOP
    * Class::MOP::Class
    * Class::MOP::Instance
    * Class::MOP::Attribute
    * Class::MOP::Method::Accessor
    * Class::MOP::Method::Constructor
      - Include stack traces in the deprecation warnings introduced in
        0.80_01. (Florian Ragwitz)

    * MOP.xs
      - Avoid c compiler warnings by declaring some unused function
        arguments. (Florian Ragwitz)

0.80_01 Sun, April 5, 2009
    * Makefile.PL
      - Make sure to preserve any compiler flags already defined in
        Config.pm. Patch by Vincent Pit. RT #44739.

    * Many methods have been renamed with a leading underscore, and a
      few have been deprecated entirely. The methods with a leading
      underscore are considered "internals only". People writing
      subclasses or extensions to Class::MOP should feel free to
      override them, but they are not for "public" use.

      - Class::MOP::Class
        - construct_class_instance => _construct_class_instance (use new_object)
        - construct_instance => _construct_instance (use new_object)
        - check_metaclass_compatibility => _check_metaclass_compatibility
        - create_meta_instance => _create_meta_instance (use get_meta_instance)
        - clone_instance => _clone_instance (use clone_object)
        - compute_all_applicable_methods is deprecated, use get_all_methods
        - compute_all_applicable_attributes is deprecated, use get_all_attributes

      - Class::MOP::Instance
        - bless_instance_structure is deprecated and will be removed
          in a future release

      - Class::MOP::Module
        - create has been renamed to _instantiate_module. This method
          does not construct an object, it evals some code that
          creates the relevant package in Perl's symbol table.

      - Class::MOP::Method::Accessor
        - initialize_body => _initialize_body (this is always called
          when an object is constructed)
        - /(generate_.*_method(?:_inline)?)/ => '_' . $1

      - Class::MOP::Method::Constructor
        - initialize_body => _initialize_body (this is always called
          when an object is constructed)
        - /(generate_constructor_method(?:_inline)?)/ => '_' . $1
        - attributes => _attributes
        - meta_instance => _meta_instance

0.80 Wed, April 1, 2009
    * Class::MOP::*
      - Call user_class->meta in fewer places, with the eventual goal
        of allowing the user to rename or exclude ->meta
        altogether. Instead uses Class::MOP::class_of. (Sartak)

    * Class::MOP
      - New class_of function that should be used to retrieve a
        metaclass. This is unlike get_metaclass_by_name in that it
        accepts instances, not just class names. (Sartak)

    * Class::MOP
      - load_first_existing_class didn't actually load the first
        existing class; instead, it loaded the first existing and
        compiling class.  It now throws an error if a class exists (in
        @INC) but fails to compile.  (hdp)

    * Class::MOP
    * Class::MOP::Class
      - we had some semi-buggy code that purported to provide a
        HAS_ISAREV based on whether mro had get_isarev (due to an
        oversight, it always returned 1). Since mro and MRO::Compat
        have always had get_isarev, HAS_ISAREV was pointless. This
        insight simplified the subclasses method by deleting the
        pure-perl fallback. HAS_ISAREV is now deprecated. (Sartak)

0.79 Fri, March 29, 2009
    * No changes from 0.78_02.

0.78_02 Thu, March 26, 2009
    * Class::MOP::Class
    * Class::MOP::Immutable
      - A big backwards-incompatible refactoring of the Immutable API,
        and the make_immutable/make_mutable pieces of the Class
        API. The core __PACKAGE__->meta->make_immutable API remains
        the same, however, so this should only affect the most
        guts-digging code.

    * XS code
      - The XS code used a macro, XSPROTO, that's only in 5.10.x. This
        has been fixed to be backwards compatible with 5.8.x.

    * Class::MOP::Class
      - Add a hook for rebless_instance_away (Sartak)
      - Use blessed instead of ref to get an instance's class name
        in rebless_instance. (Sartak)

0.78_01 Wed, March 18, 2009
    * Class::MOP::*
      - Revised and reorganized all of the API documentation. All
        classes now have (more or less) complete API documentation.

    * Class::MOP::Class
    * Class::MOP::Instance
      - Reblessing into a package that supports overloading wasn't
        properly adding overload magic to the object due to a bug
        in (at least) 5.8.8. We now use $_[1] directly which seems
        to set the magic properly. (Sartak)

    * Class::MOP::Attribute
      - The process_accessors method is now private. A public alias
        exists (and will stick around for a few releases), but it
        warns that calling the public method is deprecated.

    * Class::MOP::Method::Generated
      - Removed the new and _new methods, since this is an abstract
        base class, and all existing subclasses implement their own
        constructors.

    * MOP.xs
      - Stop is_class_loaded from thinking a class is loaded if it
        only has an empty GV (Florian Ragwitz).
        - Add a test for this (Yappo).
      - Refactor get_all_package_symbols to allow short-circuiting
        (Florian Ragwitz).
        - Use this in is_class_loaded (Florian Ragwitz).
      - Stop segfaulting when trying to get the name from a sub that's
        still being compiled (Florian Ragwitz).
        - Add tests for this (Florian Ragwitz).
      - Prefix all public symbols with "mop_" (Florian Ragwitz).
      - Clean up and simplify prehashing of hash keys (Florian Ragwitz).
      - Simplify creating simple xs reader methods (Florian Ragwitz).
      - Make everything compile with c++ compilers (Florian Ragwitz).
      - Upgrade ppport.h from 3.14 to 3.17 (Florian Ragwitz).

    * Tests
      - Remove optional test plans for tests depending on Sub::Name as
        we have a hard dependency on Sub::Name anyway (Florian Ragwitz).

    * Makefile.PL
      - Rebuild all c code if mop.h has changed (Florian Ragwitz)

0.78 Mon, February 23, 2009
    * No changes from 0.77_01

0.77_01 Sun, February 22, 2009
    * Everything
      - This package now requires its XS components. Not using
        Sub::Name lead to different behavior and bugginess in the pure
        Perl version of the code. A Moose test would fail when run
        against the pure Perl version of this code.

    * Class::MOP::Instance
      - The inline_* methods now quote attribute names themselves, and
        don't expect to receive a quoted value.


0.77 Sat, February 14, 2009
    * MOP.xs
      - Avoid assertion errors on debugging perls in is_class_loaded
        (Florian Ragwitz)

    * Class::MOP
      - Fixed various corner cases where is_class_loaded incorrectly
        returned true for a class that wasn't really loaded. (Dave
        Rolsky)

    * Class::MOP::Class
      - Add get_all_method_names (Sartak)
      - Add a wrapped_method_metaclass attribute (Florian Ragwitz)

    * Class::MOP::Package
      - Disable deprecated get_all_package_symbols in list
        context. (Florian Ragwitz)

    * Makefile.PL
      - Make sure we generate a BSD-compatible Makefile (Florian
        Ragwitz)

    * Class::MOP::Class
      - The misspelled "check_metaclass_compatability" method we've
        kept around for backwards compat_i_bility will be removed in a
        near future release. You've been warned.

0.76 Thu, January 22, 2009
    * Class::MOP::Method::Generated
      - Added new private methods to support code generation, which
        are being used by Moose and can be used by MooseX
        authors. (mst)
      - Generated methods are now generated with a #line directive
        reflecting the source of the generated method. (nothingmuch)

    * Class::MOP::Class
      - Clarified documentation of methods that return
        Class::MOP::Method objects. (doy)

    * Class::MOP
      - Clarified documentation of the metaclass cache methods. (Sartak)

    * Tests
      - Add test showing how the xs Class::MOP::is_class_loaded can
        be made to operate differently to the pure perl version (t0m)

0.75 Wed, December 31, 2008
    * Class::MOP::Class
      - A class that was made immutable and then mutable could end up
        sharing an immutable transformer object
        (Class::MOP::Immutable) with other classes, leading to all
        sorts of odd bugs. Reported by t0m. (Dave Rolsky)

0.74 Tue, December 25, 2008
    * MOP.xs
      - Add an xs implementation of Class::MOP::is_class_loaded (closes
        RT#41862). Based on a patch by Goro Fuji. (Florian Ragwitz)
      - Changed internals to make prehashing of hash keys easier and less
        error-prone. (Florian Ragwitz)
    * Class::MOP::Class
      - Fix documentation to show that around modifiers happen on both
        sides of the modified method. (Dave Rolsky)

0.73 Tue, December 16, 2008
    * MOP.xs
      - Don't use Perl_mro_meta_init. It's not part of the public perl
        api. Fixes failures to build on Win32 (RT #41750).  (Florian
        Ragwitz)
    * t/082_get_code_info.t
      - Add $^P &= ~0x200; (per Ovid's suggestion) in order to not
        munger anonymous subs when under -d and so making the tests
        succeed in that case.

0.72 Mon, December 8, 2008
    * Class::MOP::Package
      - Pass options to _new, so subclass' attributes can be
        initialized (Sartak)
    * Class::MOP::Method
      - In the docs, indicate that package_name and name are required
        when calling ->wrap (Stefan O'Rear)

0.71_02 Fri, December 5, 2008
    * Class::MOP::Immutable
      - Added a new attribute, inlined_constructor, which is true if
        the constructor was inlined.
    * Class::MOP::Package
      - Make get_all_package_symbols return a hash ref in scalar
        context and deprecate calling it in list context with a
        warning. (Florian Ragwitz)
    * MOP.xs
      - Various improvements and refactoring, making things more robust and
        easier to maintain. (Florian Ragwitz)

0.71_01 Wed, December 3, 2008
    * Class::MOP::Method
      - Add an "execute" method to invoke the body so
        we can avoid using the coderef overload (Sartak)
    * Class::MOP::Immutable
      - When we memoize methods, get their results lazily
        to remove some compile-time cost (Sartak)
      - Small speedup from eliminating several method
        calls (Sartak)
    * Class::MOP::Class
      - Some small internal tweaks to try to reduce the number of
        times we call get_method_map when bootstrapping the MOP. This
        might make loading Class::MOP (and Moose) a little
        faster. (Dave Rolsky)
      - Implemented an optional XS version of get_method_map. Mostly
        taken from a patch by Goro Fuji (rt.cpan.org #41080), with
        help form Florian Ragwitz. (Dave Rolsky)
      - Make the behaviour of of get_all_package_symbols (and
        therefore get_method_map) consistent for stub methods. Report
        and test by Goro Fuji (rt.cpan.org #41255). (Florian Ragwitz)

0.71 Wed November 26, 2008
    * Class::MOP::Class
    * Class::MOP::Module
      - Actual package creation has moved upward from
        Class to Module so that Moose roles can share
        the code (Sartak)

0.70_01 Mon, November 19, 2008
    * Class::MOP
      - Fixes for failures with blead (Florian Ragwitz)
      - Silenced compiler warnings (Florian Ragwitz)

0.70 Fri, November 14, 2008
    * Class::MOP
      - Fixed an odd corner case where the XS version of
        get_all_package_symbols could cause a segfault. This only
        happened with inlined constants in Perl 5.10.0 (Florian
        Ragwitz)

0.69 Fri, November 7, 2008
    * Class::MOP::Method::Wrapped
      - Added introspection methods for method modifiers (Dave Rolsky)


0.68 Fri October 24, 2008
    * Class::MOP
      - Make load_class require by file name instead of module name.
        This stops confusing error messages when loading '__PACKAGE__'.
        (Florian Ragwitz)
      - Add load_one_class_of function to enable you to load one of a
        list of classes, rather than having to call load_class multiple
        times in an eval. (t0m)

0.67 Tue October 14, 2008
    * Class::MOP::Class
      - Call a method on the class after setting the superclass list
        so that we can get Perl to detect cycles before MRO::Compat
        spirals into an infinite loop (sartak)
        - Reported by Schwern, [rt.cpan.org #39001]
      - In create(), pass unused options on to initialize()
        - added test for this

0.66 Sat September 20, 2008
    !! This release has an incompatible change regarding !!
       introspection of a class's method with Class::MOP::Class !!

    * Tests and XS
      - We (us maintainers) now run all tests with XS and then without
        XS, which should help us catch skew between the XS/pure Perl
        code. (Dave Rolsky)

    * Class::MOP::Class
      ! The alias_method method has been deprecated. It now simply
        calls add_method instead. There is no distinction between
        aliased methods and "real" methods.

        This means that methods added via alias_method now show up as
        part of the class's method list/map. This is a backwards
        incompatible change, but seems unlikely to break any
        code. Famous last words. (Dave Rolsky)

    * Class::MOP::Class
      - Fixed the spelling of "compatibility", but we still have a
        "check_metaclass_compatability" method for backwards
        compatibility.

0.65 Mon September 1, 2008
    For those not following the series of dev releases, the changes
    from 0.64 from 0.65 can mostly be summed up as a lot performance
    improvements by nothingmuch, including new optional XS versions of
    some methods. Also, Class::MOP now works _without_ any XS modules,
    for sad systems without a compiler.

    * Class::MOP::Method
      - Added name and package_name XS accessors, and make sure all
        the XS and Perl versions work the same way. (Dave Rolsky)

    * MOP.xs
      - The XS versions of various methods just returned undef when
        called class methods, rather than dying like the pure Perl
        versions. (Dave Rolsky)

0.64_07 Fri August 29, 2008
    * Class::MOP
      - Silenced warnings that managed to break Moose tests when XS
        was loaded. (Dave Rolsky)
      - Some XS versions of methods were ignored because of typos in
        MOP.xs. (Dave Rolsky)

0.64_06 Mon August 25, 2008
    * Class::MOP (MOP.xs)
      - Another MS VC++ fix, cannot declare a variable in the middle
        of a scope (Taro Nishino).

0.64_05 Sun August 24, 2008
    * Class::MOP
      - None of the dev releases actually loaded the XS properly, but
        we silently fell back to the pure Perl version of the
        code. (Dave Rolsky)

    * Class::MOP (MOP.xs)
      - Replaced some code that used functions not available on Visual
        C++ with some Perl XS API bits (Dave Rolsky).

0.64_04 Sat August 23, 2008
    * Class::MOP::Class
      - Workaround a bug in 5.8.1's goto sub (nothingmuch)

    * pod.t and pod_coveraget.t
      - These are no longer shipped with the tarball because of bogus
        failures from CPAN testers. (Dave Rolsky)

0.64_03 Thu August 21, 2008
    * Class::MOP::Package
      - Some (legit) code was misparsed by earlier 5.8.x
        releases. (nothingmuch)

    * Class::MOP
      - Fix a constant in void context warning (nothingmuch)

0.64_02 Thu August 21, 2008
    * Makefile.PL and Class::MOP
      - Explicitly require Perl 5.8.0+ (Dave Rolsky)

    * Makefile.PL
      - Add missing prereqs that got lost in the switch away from
        Module::Install.

    * Class::MOP::Instance
      - New method - get_all_attributes (nothingmuch)

0.64_01 Wed August 20, 2008
    * Makefile.PL
      - We now check to see if you have a compiler. If you don't, the
        module installs without some XS bits, but will work the same
        as with XS. This should make it easier to install on platforms
        without a compiler (like Windows). (Dave Rolsky)

    * many modules
      - Perl 6 style attribute naming replaced with sane style ('methods', not
        '%!methods'). These changes should not impact any existing API uses.
        (nothingmuch).

    * many modules
      - Quite a number of optimizations based on profiling, including
        allowing constructors to take hash references instead of
        hashes, duplicating some frequently used code in XS, and
        making constructors immutable. These changes should not impact
        any existing API uses. (nothingmuch)

    * Many modules
      - Constructors now respect the meta attributes of their subclasses,
        facilitating MOP extensibility. More related changes will happen in the
        next several releases. (nothingmuch)

    * Class::MOP::Class
      - New method - get_all_methods, replaces the deprecated
        compute_all_applicable_methods. get_all_attributes provided for
        consistency (nothingmuch)
      - New method - wrap_method was refactored out of get_method_map
        (nothingmuch)
      - New API for meta instance invalidation - invalidate_meta_instance,
        invalidate_meta_instances, add_dependent_meta_instance,
        remove_dependent_meta_instance, called automatically when attribute
        definitions change and allows notification of dependent subclasses.
        (nothingmuch)

0.64 Sun August 3, 2008
    * Class::MOP::Immutable
      - fixing subtle edge case in immutable when you
        call ->meta (stevan)
      - clean up option processing (nothingmuch)

    * Class::MOP::Instance
      - inlined initialize slot didn't match
        non-inlined (nothingmuch)

0.63 Mon July 7, 2008
    * Class::MOP
      - load_class will initialize a metaclass even if
        the class is already loaded (sartak)
      - load_class now returns the metaclass instance
        instead of just 1 (sartak)

    * elsewhere
      - better error messages (sartak and Dave Rolsky)

0.62 Wed June 18, 2008
    - in is_class_loaded, recognize scalar references (as opposed to globs) in
      the symbol table as methods (these are optimized constant subs)

0.61 Fri. June 13, 2008
    - Okay, lets give this another try and see if PAUSE
      recognizes it correct this time.

0.60 Thurs. Jun 12, 2008
    - Fixed a version number issue by bumping all modules
      to 0.60.

0.59 Thurs. Jun 12, 2008
    !! Several fixes resulting in yet another 25-30% speedup !!

    * Class::MOP::Class
      - now stores the instance of the instance
        metaclass to avoid needless recomputation
        and deletes it when the cache is blown
      - introduce methods to query Class::MOP::Class for
        the options used to make it immutable as well as
        the proper immutable transformer. (groditi)

    * Class::MOP::Package
      - {add, has, get, remove}_package_symbol all
        now accept a HASH ref argument as well as the
        string. All internal usages now use the HASH
        ref version.

    * Class::MOP
      - MOP.xs does sanity checks on the coderef
        to avoid a segfault
      - is_class_loaded check now uses code that
        was improved in Moose's ClassName type
        check (Sartak)
      - nonsensical (undef, empty, reference) class
        names now throw a more direct error in
        load_class (Sartak)
        - tests for this and other aspects of
          load_class (Sartak)

    * Class::MOP
      Class::MOP::Class
      Class::MOP::Method
      Class::MOP::Method::Wrapped
      Class::MOP::Attribute
      - switched usage of reftype to ref because
        it is much faster

0.58 Thurs. May 29, 2008
    (late night release engineering)--

    - fixing the version is META.yml, no functional
      changes in this release

0.57 Wed. May 28, 2008
    !! Several speedups resulting in 20-25% speedups !!
    || (thanks to konobi, groditi, mst & CataMoose) !!

    * Class::MOP::Class
      - made get_method_map use list_all_package_symbols
        instead of manually grabbing each symbol
      - streamlining &initialize somewhat, since it gets
        called so much

    * Class::MOP::Package
      - made {get, has}_package_symbol not call
        &namespace so much
      - inlining a few calls to &name with
        direct HASH access key access
      - added get_all_package_symbols to fetch
        a HASH of items based on a type filter
        similar to list_all_package_symbols
        - added tests for this

    * Class::MOP::Method
      Class::MOP::Method::Constructor
      Class::MOP::Method::Generated
      Class::MOP::Method::Accessor
      - added more descriptive error message to help
        keep people from wasting time tracking an error
        that is easily fixed by upgrading.

    * Class::MOP::Immutable
      - Don't inline a destructor unless the user actually
        needs one
        - added tests for this

0.56 Saturday, May 24, 2008
    * Class::MOP
      - we now get the &check_package_cache_flag
        function from MRO::Compat
      - All XS based functionality now has a
        Pure Perl alternative
        - the CLASS_MOP_NO_XS environment variable
          can now be used to force non-XS versions
          to always be used

    * Class::MOP::Attribute
      - add has_read_method and has_write_method
      - get_{read,write}_method_ref now wraps the
        anon-sub ref in the method metaclass when
        possible
        - added tests for this

    * Class::MOP::Immutable
      - added the ability to "wrap" methods when
        making the class immutable

    * Class::MOP::Class
      - now handling the edge case of ->meta->identifier
        dying by wrapping add_package_symbol to specifically
        allow for it to work.
        - added tests for this

    * Class::MOP::Attribute
      Class::MOP::Class
      Class::MOP::Immutable
      - any time a method meta object is constructed
        we make sure to pass the correct package and
        method name information

    * Class::MOP::Method
      Class::MOP::Method::Wrapped
      Class::MOP::Method::Generated
      Class::MOP::Method::Accessor
      Class::MOP::Method::Consructor
      - the &wrap constructor method now requires that a
        'package_name' and 'name' attribute are passed. This
        is to help support the no-XS version, and will
        throw an error if these are not supplied.
      - all these classes are now bootstrapped properly
        and now store the package_name and name attributes
        correctly as well

    ~ Build.PL has been removed since the
      Module::Install support has been removed

0.55 Mon. April 28, 2008
    - All classes now have proper C3 MRO support
      - added MRO::Compat as a dependency to allow
        for the C3 MRO support to Just Work in all
        perl versions

    * Class::MOP::Class
      - rebless_instance now returns the instance
        it has just blessed, this is mostly to
        facilitate chaining
      - set the attr correctly in rebless_instance
        when it has no init_arg
      - tweaked &linear_isa and &class_precedence_list
        to support c3 classes.

0.54 Fri. March, 14, 2008
    * Class::MOP
      metaclass.pm
      - making sure that load_class never gets
        passed a value from @_ or $_ to squash
        Ovid's bug (http://use.perl.org/~Ovid/journal/35763)

    * Class::MOP::Class
      - make_{immutable,mutable} now return 1
        (cause Sartak asked)
      - improved error handling in ->create method
      - rebless_instance now takes extra params which
        will be used to populate values
        - added tests for this

    * Class::MOP::Object
      - localizing the Data::Dumper configurations so
        that it does not pollute others (RT #33509)

    * Class::MOP::Class
      Class::MOP::Package
      Class::MOP::Module
      Class::MOP::Method
      Class::MOP::Attribute
      - these classes no longer define their own ->meta,
        but instead just inherit from Class::MOP::Object

    * Class::MOP::Instance
      Class::MOP::Immutable
      - these classes now inherit from Class::MOP::Object

    * t/
      - fixed the filename length on several
        test files so we install on VMS better
        (RT #32295)
      - fixed incorrect use of catdir when it
        should be catfile (RT #32385)

0.53 Thurs. Feb. 14, 1008
    ~~ several doc. fixes and updates ~~

    * Class::MOP::Class
      Class::MOP::Method::Constructor
      Class::MOP::Attribute
        - making init_arg accept an undefined value
          to indicate that no constructor args can
          be passed (thanks to nothingmuch)
          - added tests for this
        - added attribute initializer attribute (rjbs)

    * Class::MOP.
        - making this use the new init_arg => undef
          feature instead of the silly hack from
          before (thanks to nothingmuch)

0.52 Tues. Jan. 22, 2008
    * Class::MOP::Class
      - fixed bug in rebless_instance
        (discovered by ash)

    * Class::MOP::Method::Constructor
      - removed assumptions about the existence of
        a &meta method

0.51 Mon. Jan. 14, 2008
    ~~~ some misc. doc. fixes ~~~
    ~~ updated copyright dates ~~

    * Class::MOP
      - now sets the IS_RUNNING_ON_5_10
        constant so that we can take advantage
        of some of the nice bits of 5.10

    * Class::MOP::Class
      - uses the IS_RUNNING_ON_5_10 flag to
        optimize the &linearized_isa method
        and avoid the hack/check for circular
        inheritence in &class_precedence_list
      - added rebless_instance method (Sartak)
        - added tests for this

    * Class::MOP::Immutable
      - the immutable class now keeps track of
        the transformer which immutablized it

    * Class::MOP::Instance
      - added rebless_instance_structure method (Sartak)
        - added tests for this

0.50 Fri. Dec. 21, 2007
    * Class::MOP::Class
      - fixed bug in immutable to make sure that
        transformation arguments are saved
        correctly (mst)
        - added tests for this

    * Class::MOP::Immutable
      - fixed a bug (see above)

    * Class::MOP::Attribute
      - some doc updates

0.49 Fri. Dec. 14, 2007
    !! Class::MOP now loads 2 x faster  !!
    !! with XS speedups (thanks konobi) !!

    * Class::MOP
      - removed the dependency on B
      - added two XS functions (thanks konobi)
        - get_code_info($code) which replaces all
          the B fiddling we were doing with
          faster/leaner XS level fiddling
        - check_package_cache_flag($pkg_name) which
          returns the PL_sub_generation variable to
          be used to help manage method caching.

          NOTE:
          In 5.10 or greater this will actually
          use the mro::get_pkg_gen instead to give
          even more accurate caching information.
          blblack++ for that stuff :)

    * Class::MOP::Class
      - added the &subclasses method (thanks rlb)
      - added the update_package_cache_flag and
        reset_package_cache_flag which help keep
        track of when we need to re-fetch the
        method map.
      - Several small improvements to take advantage
        of the new method map caching features

0.48 Mon. Nov. 26, 2007
    * Class::MOP::Attribute
      - fixed get_read/write_method to handle the
        HASH ref case, which makes the
        get_read/write_method_ref handle it too.
        - added more tests for this

0.47 Sat. Nov. 24, 2007
    * Class::MOP::Attribute
      - fixed misspelling in get_write_method_ref
        - added more tests for this

0.46 Fri. Nov. 23, 2007
    * Class::MOP::Class
      - added the linearized_isa method instead of constantly
        pruning duplicate classes (this will be even more
        useful in the 5.10-compat version coming soon)

    * Class::MOP::Attribute
      - added the get_read_method_ref and get_write_method_ref
        methods which allow you to retrieve a CODE ref which
        can always be used to read or write an attribute.

0.45 Thurs. Nov. 13, 2007
    * Class::MOP::Attribute
      - Fix error message on confess (groditi)

0.44 Thurs. Nov. 13, 2007
    - Apparently I didn't make dist correctly (groditi)

0.43 Thurs. Nov. 13, 2007
    * Class::MOP
      - Add support for the 'builder' attribute (groditi)

        construct_class_instance (groditi)
      - duplicate check into initialize to save a
        call through (groditi)

    * Class::MOP::Attribute
      - Add support for the 'builder' attribute (groditi)
      - Make predicates check for the existence of a value, not whether
        it is defined (groditi)

    * Class::MOP::Instance
      - Make predicates check for the existence of a value, not whether
        it is defined (groditi)

    * Class::MOP::Method::Accessor
      - made this a subclass of Class::MOP::Method::Generated
        - removed the relevant attributes

    * Class::MOP::Method::Constructor
      - fixed the cached values we had to be more sane
      - made this a subclass of Class::MOP::Method::Generated

        subclasses now.
        - added tests for this
      - added the option to allow for both inlined and
        non-inlined constructors.
      - Update inlined methods for builder and predicate changes (groditi)

    * Class::MOP::Method::Generated
      - added this class as an abstract base for the
        Class::MOP::Method::{Constructor,Accessor} classes
        - added tests for this

    *t/
      - Alter tests (005, 014 020, 021) for new builder addition (groditi)
      - Tests for new predicate behavior (and corrections to old tests) (groditi)

0.42 Mon. July 16, 2007
    !!! Horray for mst, he fixed it !!!

    * Class::MOP::Package
      - alter symbol table handling to deal with 5.8.x and 5.9.x

    * t/
      - Get rid of the crappy workaround from 0.40/41

0.41 Sun. July 15, 2007
    * t/
        Arghh!!! My TODO test didn't work, so I handle
        it manually now so that people can use this
        with 5.9.5/bleadperl without issue.

0.40 Tues, July 3, 2007
    * t/
      ~ marked a test in 003_methods.t as TODO
        for perl 5.9.5 (this test is irrelvant to
        the module functioning on 5.9.5 for the most
        part anyway)

0.39 Mon. June 18, 2007
    * Class::MOP::Immutable
      - added make_metaclass_mutable + docs (groditi)
      - removed unused variable
      - added create_immutable_transformer
        necessary for sane overloading of immutable behavior
         - tests for this (groditi)

    * Class::MOP::Class
      - Immutability can now be undone,
        added make_mutable + tests + docs (groditi)
      - Massive changes to the way Immutable is done
        for details see comments next to make_immutable
        This fixes a bug where custom metaclasses broke
        when made immutable. We are now keeping one immutable
        metaclass instance per metaclass instead of just one
        to prevent isa hierarchy corruption. Memory use will go
        up, but I suspect it will be neglible.
         - New tests added for this behavior.  (groditi)

0.38 Thurs. May 31, 2007
    ~~ More documentation updates ~~

    * Class::MOP::Package
      - we now deal with stub methods properly
        - added tests for this
      - fixed some tests failing on 5.9.5 (thanks blblack)

    * Class::MOP::Attribute
      - added get_read_method and get_write_method
        thanks to groditi for this code, tests
        and docs.
        - added tests and POD for this

    * Class::MOP::Class
      - fixed RT issue #27329, clone object now
        handles undef values correctly.
        - added tests for this
      - Corrected anon-class handling so that they
        will not get reaped when instances still
        exist which need to reference them. This is
        the correct behavior, hopefully this is an
        obscure enough feature that there are not too
        many work arounds out in the wild.
        - added tests for this by groditi
        - updated docs to explain this

    * metaclass
      - load custom metaclasses automatically (thanks groditi)
        - added tests for this behavior

0.37 Sat. March 10, 2007
    ~~ Many, many documentation updates ~~

    * Class::MOP
      - added &load_class and &is_class_loaded
        - added tests and docs for these

    * Class::MOP::Attribute
      - default now checks the instance with defined to
        avoid setting off bool-overloads (found by Carl Franks)

0.37_002
    * /t
      - bad name in a test, causing meaningless failuress.
        No other changes.

0.37_001

    ~~ GLOBAL CHANGES ~~
    - All attribute names are now consistent and follow Perl 6
      style (prefixed with the sigil, and ! as the twigil for
      private attrs). This should not affect any code, unless
      you broke encapsulation, in which case, it is your problem
      anyway.

    !! Class::MOP::Class::Immutable has been removed

    * Class::MOP::Method::Constructor
      - this has been moved out of Class::MOP::Class::Immutable
        and is a proper subclass of Class::MOP::Method now.

    * Class::MOP::Class
      - this module now uses Class::MOP::Immutable for the
        immutable transformation instead of
        Class::MOP::Class::Immutable.

    + Class::MOP::Immutable
      - this module now controls the transformation from a mutable
        to an immutable version of the class. Docs for this will
        be coming eventually.


0.36 Sun. Nov. 5, 2006
    * Class::MOP::Class
      - added a few 'no warnings' lines to keep annoying
        (and meaningless) warnings from chirping during
        global destruction.

    * Class::MOP
      - some more bootstrapping is now done on the new
        classes

    * Class::MOP::Class::Immutable
      *** API CHANGE ***
      - constructor generation is now handled by
        the Class::MOP::Method::Constructor class

    * Class::MOP::Method::Constructor
      - created this to handle constructor generation
        in Class::MOP::Class::Immutable

    * Class::MOP::Attribute
      *** API CHANGE ***
      - attributes now delegate to the
        Class::MOP::Method::Accessor to generate
        accessors

    * Class::MOP::Method::Accessor
      - all accessor generation functions from
        Class::MOP::Attribute have been moved here

0.35 Sat. Sept. 30, 2006

    * scripts/class_browser.pl
      - initial prototype of a class browser, more
        on this to come. Comments and patches are
        very much welcome.

    * Class::MOP
      - All Class::MOP::* accessors are no longer
        re-generated in the bootstrap, instead
        they are aliased from the originals
        - fixed tests to reflect
      - added Class::MOP::Method (and its subclasses)
        to the bootstrap
        - adjusted tests for this
      - added the Class::MOP::Instance attributes
        to the bootstrap

        - adjusted tests to compensate
        - adjusted docs for this

    * Class::MOP::Class
      - changed how methods are dealt with to
        encapsulate most of the work into the
        &get_method_map method
      - made several adjustments for the change
        in Class::MOP::Method
      - &add_attribute now checks if you are adding
        a duplicate name, and properly removes the
        old one before installing the new one
        - added tests for this
        - adjusted docs for this

    * Class::MOP::Class::Immutable
      - added caching of &get_method_map
      - fixed issue with &get_package_symbol
      - cleaned up the methods that die (patch by David Wheeler)

    * Class::MOP::Package
      - added filtering capabilities to
        &list_all_package_symbols

0.34 Sat. Aug. 26, 2006
    * Class::MOP::Class
      - added the %:methods attribute, which like
        the $:version and such just actually goes
        to the symbol table to get it's stuff.
        However, it makes the MOP more complete.
     ** API CHANGE **
      - The &create method now requires that all
        but the package name now is passed in as
        named parameters. See docs for more info.
        - updated docs and tests for this

    * Class::MOP::Object
      - added &dump method to easily Data::Dumper

        the bootstrap

    ~ lots of misc. test cleanup

0.33 Sat. Aug. 19, 2006
    * Class::MOP::Class
      - moved the metaclass cache out of here
        and it is now in Class::MOP itself.

    * Class::MOP
      - moved all the metaclass cache stuff here
        - fixed all tests for this

    * Class::MOP::Attribute
      - reference values (other than CODE refs)
        are no longer allowed for defaults
        - added tests for this

    * Class::MOP::Package
      - fixed an issue with perl 5.8.1 and how it deals
        with symbol tables. The namespace hash is now
        always reloaded from the symbol table.

    ~ lots of misc. documentation cleanup

0.32 Sat. Aug. 12, 2006
    + added Class::MOP::Object so that the
      metamodel is more complete (and closer
      to what Perl 6 will probably be).

    * Class::MOP::Package
      - refactored entire class, this is now
        the primary gateway between the metaclass
        and the Perl 5 symbol table
        - added many tests for this
      - this class is now a subclass of
        Class::MOP::Object
        - added some tests to reflect this

    * Class::MOP::Class

        use Class::MOP::Package methods instead

    * Class::MOP::Module
      - adding the $:version attribute in the bootstrap
        so that Module has a version as an attribute
        - see comment in Class::MOP for details
      - added the $:authority attribute to this module
        as well as an &identifier method, to bring us
        ever closer to Perl 6 goodness
        - I have added $AUTHORITY to all the modules
        - added tests for this

    * Class::MOP::Instance
      - added &deinitialize_slot for removing slots
        from an instance
        - added tests for this

    * Class::MOP::Attribute
      - added support for &deinitialize_slot for removing
        slots from an instance
        - added tests for this

0.31 Sat. July 15, 2006

      - added &find_method_by_name to locate a method
        anywhere within the class hierarchy

      - added &set_value and &get_value for getting
        the value of the attribute for a particular
        instance.

0.30 Wed. July 5, 2006
    ---------------------------------------
    This is the first version of Class::MOP
    to introduce the immutable features which
    will be used for optimizating the MOP.
    This support should still be considered
    experimental, but moving towards stability.
    ---------------------------------------

    * Created Class::MOP::Class::Immutable

    * Created the Class::MOP::Package and
      Class::MOP::Module classes to more
      closely conform to Perl 6's meta-model

    * Class::MOP::Class
      - now inherits from Class::MOP::Module
      - several methods moved to ::Module and
        ::Package and now inherited
        - added tests for this

    * Class::MOP::Instance
      - added an is_inlinable method to allow other
        classes to check before they attempt to optimize.
      - added an inline_create_instance to inline
        instance creation (of course)

    ** API CHANGE **
      - the Class::MOP::Class::*_package_variable
        methods are all now methods of Class::MOP::Package
        and called *_package_symbol instead. This is
        because they are now more general purpose symbol
        table manipulation methods.

0.29_02 Thurs. June 22, 2006
    ++ DEVELOPER RELEASE ++
    * Class::MOP::Class
      - small change in &create so that it behaves
        properly when inherited
      - small fix to &clone_instance

0.29_01 Fri. May 12, 2006
    ++ DEVELOPER RELEASE ++
      - This release works in combination with
        Moose 0.09_01, it is a developer release
        because it introduces a new instance
        sub-protocol and has not yet been
        optimized.

    * Class::MOP::Class
      - anon-classes are now properly garbage collected
        - added tests for this
      - improved method modifier wrapping

    * Class::MOP::Instance
      - added new instance protocol
        - added tests for this
      - changed all relevant modules and examples
        - Class::MOP::Class
        - Class::MOP::Attribute
        - examples/*

    * metaclass
      - you no longer need to specify the metaclass
        itself, if it is not there, Class::MOP::Class
        is just assumed
        - updated tests for this

    * examples/
      - added ArrayBasedStorage example to show
        instance storage using ARRAY refs instead of
        HASH refs.
        - added tests for this
      - InsideOutClass is totally revised using the
        new instance protocol
        - added more tests for this

0.26 Mon. April 24, 2006
    * Class::MOP::Class
      - added find_attribute_by_name method
        - added tests and docs for this

0.25 Thurs. April 20, 2006
    * Class::MOP::Class
      - added create_anon_class for creating anonymous classes
        - added tests for this
      - added get_all_metaclasses, get_all_metaclass_names
        and get_all_metaclass_instances method to allow
        access to all the cached metaclass objects.
      - attribute slot initialization is now the responsibility
        of the attribute itself, and construct_instance now
        delegates appropriately

    * Class::MOP::Attribute
      - attribute slot initialization is now the responsibility
        of the attribute itself, so we added a method for it
        called initialize_instance_slot

    * examples/
      - adjusted all the examples to use the new attribute
        initialize_instance_slot method

0.24 Tues. April 11, 2006
    * Class::MOP::Class
      - cleaned up how the before/after/around method
        modifiers get named with Sub::Name

0.23 Thurs. March 30, 2006
	* Class::MOP::Class
	  - fixed the way attribute defaults are handled
	    during instance construction (bug found by chansen)

	* Class::MOP::Attribute
	  - read-only accessors ('reader') will now die if
	    passed more than one argument (attempting to write
	    to them basically)
	      - added tests for this
	      - adjusted all /example files to comply

0.22 Mon. March 20, 2006
    * Class::MOP::Class
      - localized $@ in the *_package_variable functions
        because otherwise, it does ugly things in Moose.
          - added test case for this

0.21 Wed. March 15, 2006
    * Class::MOP::Class
      - fixed issue where metaclasses are reaped from
        our cache in global destruction, and so are not
        available in DESTORY calls

0.20 Thurs. March 2, 2006
    - removed the dependency for Clone since
      we no longer to deep-cloning by default.

    * Class::MOP::Method
      - added &package_name, &name and
        &fully_qualified_name methods, some of
        which were formerly private subs in
        Class::MOP::Class

    * Class::MOP::Method::Wrapped
      - allows for a method to be wrapped with
        before, after and around modifiers
          - added tests and docs for this feature

    * Class::MOP::Class
      - improved &get_package_symbol
          - &version and &superclasses now use it
      - methods are now blessed into Class::MOP::Method
        whenever possible
      - added methods to install CLOS-style method modifiers
         - &add_before_method_modifier
         - &add_after_method_modifier
         - &add_around_method_modifier
             - added tests and docs for these
      - added &find_next_method_by_name which finds the
        equivalent of SUPER::method_name

0.12 Thurs. Feb 23, 2006
    - reduced the dependency on B, no need to always
      have the latest

    * examples/
      - added docs to the C3 method dispatch order test
      - fixed missing Algorithm::C3 dependency by making
        the test skip if it is not installed

0.11 Mon Feb. 20, 2006
    * examples/
      - added example of changing method dispatch order to C3

    * Class::MOP::Class
      - changed how clone_instance behaves, it now only does a
        shallow clone (see docs for more details)
        - added docs and tests

0.10 Tues Feb. 14, 2006
    ** This release was mostly about writing more tests and
       cleaning out old and dusty code, the MOP should now
       be considered "ready to use".

    - adding more tests to get coverage up a little higher,
      mostly testing errors and edge cases.
      - test coverage is now at 99%

    * Class::MOP
      - no longer optionally exports to UNIVERSAL::meta or
        creates a custom metaclass generator, use the
        metaclass pragma instead.

    * Class::MOP::Class
      - fixed a number of minor issues which came up in the
        error/edge-case tests

    * Class::MOP::Attribute
      - fixed a number of minor issues which came up in the
        error/edge-case tests

    * metaclass
      - adding new metaclass pragma to make setting up the
        metaclass a little more straightforward

    * Class::MOP
      - clean up bootstrapping to include more complete
        attribute definitions for Class::MOP::Class and
        Class::MOP::Attribute (accessors, readers, writers,
        etc.) ... it is redundant, but is useful meta-info
        to have around.

    * Class::MOP::Class
      - fixing minor meta-circularity issue with &meta, it
        is now more useful for subclasses
      - added &get_attribute_map as an accessor for the
        hash of attribute meta objects
      - &compute_all_applicable_attributes now just returns
        the attribute meta-object, rather than the HASH ref
        since all the same info can be gotten from the
        attribute meta-object itself
          - updated docs & tests to reflect
      - added &clone_instance method which does a deep clone
        of the instance structure created by &construct_instance
          - added docs & tests for this
          - added Clone as a dependency
      - added &new_object and &clone_object convience methods to
        return blessed new or cloned instances
          - they handle Class::MOP::Class singletons correctly too
          - added docs & tests for this
      - cleaned up the &constuct_class_instance so that it behaves
        more like &construct_instance (and managed the singletons too)
      - added the &check_metaclass_compatibility method to make sure
        that metaclasses are upward and downward compatible.
          - added tests and docs for this

    * examples/
      - adjusting code to use the &Class::MOP::Class::meta
        fix detailed above
      - adjusting code to use the metaclass pragma

0.05 Sat Feb. 4, 2006
    * Class::MOP::Class
      - added the &attribute_metaclass and &method_metaclass
        attributes which contain a metaclass name to use for
        attributes/methods respectively

    * Class::MOP
      - bootstrap additional attributes for Class::MOP::Class

    * examples/
      - adjusted the example code and tests to use the new
        &attribute_metaclass feature of Class::MOP::Class
      - added new example:
        - LazyClass

0.04 Fri Feb. 3, 2006

      - attributes are now associated with class directly

    * examples/
      - refactored the InsideOut example to take advantage
        of the Class::MOP::Attribute refactoring
      - changed example files to .pod files and hide thier
        package names from PAUSE (I don't want to own these
        namespaces really, they are just examples)

0.02 Thurs Feb. 2, 2006
    - moving examples from t/lib/* to examples/*
        - adding POD documentation to the examples

0.01 Thurs Feb. 2, 2006
    - Initial release
