    * Class::MOP::Class
      Class::MOP::Method::Constructor
      Class::MOP::Attribute

0.52 Tues. Jan. 22, 2008
    * Class::MOP::Class
      - fixed bug in rebless_instance

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)

    * Class::MOP::Class
      - optimise metaclass-already-exists check in 
        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
      - fixed generated constructor so it properly handles 
        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)

    *examples/
      - Update ArrayRef based class example to work with predicate changes

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
    
    * Class::MOP::Method
      *** API CHANGE ***
      - methods are no longer blessed CODE refs
        but are actual objects which can be CODE-ified
        - 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 
        an object
        
    * Class::MOP
      - cleaned up the initialization of attributes 
        which do not store things in the instance 
      - added the %:methods attribute definition to
        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
      - refactored all symbol table access to 
        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

    * Class::MOP::Class
      - added &find_method_by_name to locate a method
        anywhere within the class hierarchy   
        
    * Class::MOP::Attribute
      - 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
      - some small optimizations

    * Class::MOP::Attribute
      - some small optimizations

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        
     
    * examples/
      - fixing the AttributesWithHistory example, it was broken.

0.06 Thurs Feb. 9, 2006
    * 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

    - converted to Module::Build instead of EU::MM
    
    * Class::MOP::Attribute
      - refactored method generation code
      - 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)
