1 Also see Moose::Manual::Delta for more details of, and workarounds
2 for, noteworthy changes.
6 - Call user_class->meta in fewer places, with the eventual
7 goal of allowing the user to rename or exclude ->meta
8 altogether. Instead uses Class::MOP::class_of. (Sartak)
10 * Moose::Meta::Method::Accessor
11 - If an attribute had a lazy default, and that value did not
12 pass the attribute's type constraint, it did not get the
13 message from the type constraint, instead using a generic
14 message. Test provided by perigrin.
16 * Moose::Util::TypeConstraints
17 - Add duck_type keyword. It's sugar over making sure an object
18 can() a list of methods. This is easier than jrockway's suggestion
19 to fork all of CPAN. (perigrin)
20 - add tests and documentation (perigrin)
23 - Document the fact that init_meta() returns the target class's
24 metaclass object. (hdp)
26 * Moose::Cookbook::Extending::Recipe1
27 * Moose::Cookbook::Extending::Recipe2
28 * Moose::Cookbook::Extending::Recipe3
29 * Moose::Cookbook::Extending::Recipe4
30 - Make init_meta() examples explicitly return the metaclass and point out
33 * Moose::Cookbook::Meta::Recipe6
34 - A new recipe, creating a custom meta-method class.
37 * Moose::Meta::Method::Constructor
38 - Attribute triggers now consistently do not receive the meta-attribute
39 object as an argument. Previously, triggers called during instance
40 construction were passed the meta-attribute, but triggers called by
41 normal accessors were not. Fixes RT#44429, reported by Mark Swayne.
44 * Moose::Manual::Attributes
45 - Remove references to triggers receving the meta-attribute object as an
48 0.73 Fri, March 29, 2009
49 * No changes from 0.72_01.
51 0.72_01 Thu, March 26, 2009
53 - Almost every module has complete API documentation. A few
54 methods (and even whole classes) have been intentionally
55 excluded pending some rethinking of their APIs.
57 * Moose::Util::TypeConstraints
58 - Calling subtype with a name as the only argument is now an
59 exception. If you want an anonymous subtype do:
61 my $subtype = subtype as 'Foo';
63 * Moose::Cookbook::Meta::Recipe7
64 - A new recipe, creating a custom meta-instance class.
66 * Moose::Cookbook::Basics::Recipe5
67 - Fix various typos and mistakes. Includes a patch from Radu
70 * Moose::Cookbook::Basics::Recipe9
71 - Link to this recipe from Moose.pm's builder blurb
74 - When wrapping a function with a prototype, Moose::Exporter now
75 makes sure the wrapped function still has the same
76 prototype. (Daisuke Maki)
78 * Moose::Meta::Attribute
79 - Allow a subclass to set lazy_build for an inherited
83 - Explicitly depend on Data::OptList. We already had this dependency
84 via Sub::Exporter, but since we're using it directly we're
85 better off with it listed. (Sartak)
87 * Moose::Meta::Method::Constructor
88 - Make it easier to subclass the inlining behaviour. (Ash
91 * Moose::Manual::Delta
92 - Details significant changes in the history of Moose, along
93 with recommended workarounds.
95 * Moose::Manual::Contributing
96 - Contributor's guide to Moose.
98 * Moose::Meta::Method::Constructor
99 - The long-deprecated intialize_body method has been removed
100 (yes, spelled like that).
102 * Moose::Meta::Method::Destructor
103 - This is_needed method is now always a class method.
106 - Changes to the internals of how make_immutable works to match
107 changes in latest Class::MOP.
109 0.72 Mon, February 23, 2009
111 * Moose::Meta::Method::Constructor
112 - A mutable class accepted Foo->new(undef) without complaint,
113 while an immutable class would blow up with an unhelpful
114 error. Now, in both cases we throw a helpful error
115 instead. Reported by doy.
117 0.71_01 Sun, February 22, 2009
119 - Hopefully fixed some POD errors in a few recipes that caused
120 them to display weird on search.cpan.org.
122 * Moose::Util::TypeConstraints
123 - Calling type or subtype without the sugar helpers (as, where,
124 message) is now deprecated.
125 - The subtype function tried hard to guess what you meant, but
126 often got it wrong. For example:
128 my $subtype = subtype as 'ArrayRef[Object]';
130 This caused an error in the past, but now works as you'd
134 - Make sure Moose.pm is loaded before calling
135 Moose->throw_error. This wasn't normally an issue, but could
136 bite you in weird cases.
138 0.71 Thu, February 19, 2009
139 * Moose::Cookbook::Basics::Recipe11
140 - A new recipe which demonstrates the use of BUILDARGS and
143 * Moose::Cookbook::Roles::Recipe3
144 - A new recipe, applying a role to an object instance. (Dave
148 - Allow overriding specific keywords from "also" packages. (doy)
151 - Replace hardcoded cookbook tests with Test::Inline to ensure
152 the tests match the actual code in the recipes. (Dave Rolsky)
155 - Working on the above turned up a number of little bugs in the
156 recipe code. (Dave Rolsky)
158 * Moose::Util::TypeConstraints::Optimized
159 - Just use Class::MOP for the optimized ClassName check. (Dave
162 0.70 Sat, February 14, 2009
163 * Moose::Util::TypeConstraints
164 - Added the RoleName type (stevan)
165 - added tests for this (stevan)
167 * Moose::Cookbook::Basics::Recipe3
168 - Updated the before qw[left right] sub to be a little more
169 defensive about what it accepts (stevan)
170 - added more tests to t/000_recipies/basics/003_binary_tree.t
174 - We now always call DEMOLISHALL, even if a class does not
175 define DEMOLISH. This makes sure that method modifiers on
176 DEMOLISHALL work as expected. (doy)
177 - added tests for this (EvanCarroll)
179 * Moose::Util::MetaRole
180 - Accept roles for the wrapped_method_metaclass (rafl)
181 - added tests for this (rafl)
183 * Moose::Meta::Attribute
184 - We no longer pass the meta-attribute object as a final
185 argument to triggers. This actually changed for inlined code a
186 while back, but the non-inlined version and the docs were
190 - Some tests tried to use Test::Warn 0.10, which had bugs. Now
191 they require 0.11. (Dave Rolsky)
194 - Lots of small changes to the manual, cookbook, and
195 elsewhere. These were based on feedback from various
196 users, too many to list here. (Dave Rolsky)
198 0.69 Thu, February 12, 2009
200 - Make some keyword errors use throw_error instead of croak
201 since Moose::Exporter wraps keywords now (Sartak)
204 - Revised every recipe for style and clarity. Also moved some
205 documentation out of cookbook recipes and into Moose::Manual
206 pages. This work was funded as part of the Moose docs grant
207 from TPF. (Dave Rolsky)
209 * Moose::Meta::Method::Delegation
210 - If the attribute doing the delegation was not populated, the
211 error message did not specify the attribute name
214 0.68 Wed, February 4, 2009
216 - Many spelling, typo, and formatting fixes by daxim.
218 * Moose::Manual::Attributes
219 - The NAME section in the POD used "Attribute" so search.cpan
220 didn't resolve links from other documents properly.
222 * Moose::Meta::Method::Overriden
223 - Now properly spelled as Overridden. Thanks to daxim for
226 0.67 Tue, February 3, 2009
228 - Lots of little typo fixes and a few clarifications. Several
229 pages didn't have proper titles, and so weren't actually
230 visible on search.cpan.org. Thanks to hanekomu for a variety
231 of fixes and formatting improvements.
233 0.66 Tue, February 3, 2009
235 - This is a brand new, extensive manual for Moose. This aims to
236 provide a complete introduction to all of Moose's
237 features. This work was funded as part of the Moose docs grant
238 from TPF. (Dave Rolsky)
240 * Moose::Meta::Attribute
241 - Added a delegation_metaclass method to replace a hard-coded
242 use of Moose::Meta::Method::Delegation. (Dave Rolsky)
244 * Moose::Util::TypeConstraints
245 - If you created a subtype and passed a parent that Moose didn't
246 know about, it simply ignored the parent. Now it automatically
247 creates the parent as a class type. This may not be what you
248 want, but is less broken than before. (Dave Rolsky)
250 * Moose::Util::TypeConstraints
251 - This module tried throw errors by calling Moose->throw_error,
252 but it did not ensure that Moose was loaded first. This could
253 cause very unhelpful errors when it tried to throw an error
254 before Moose was loaded. (Dave Rolsky)
256 * Moose::Util::TypeConstraints
257 - You could declare a name with subtype such as "Foo!Bar" that
258 would be allowed, but if you used it in a parameterized type
259 such as "ArrayRef[Foo!Bar]" it wouldn't work. We now do some
260 vetting on names created via the sugar functions, so that they
261 can only contain alphanumerics, ":", and ".". (Dave Rolsky)
263 0.65 Thu, January 22, 2008
264 * Moose and Moose::Meta::Method::Overridden
265 - If an overridden method called super(), and then the
266 superclass's method (not overridden) _also_ called super(),
267 Moose went into an endless recursion loop. Test provided by
268 Chris Prather. (Dave Rolsky)
270 * Moose::Meta::TypeConstraint
271 - All methods are now documented. (gphat)
273 * t/100_bugs/011_DEMOLISH_eats_exceptions.t
274 - Fixed some bogus failures that occurred because we tried to
275 validate filesystem paths in a very ad-hoc and
276 not-quite-correct way. (Dave Rolsky)
278 * Moose::Util::TypeConstraints
279 - Added maybe_type to exports. See docs for details. (rjbs)
282 - Added Moose::Util::TypeConstraints to the SEE ALSO
286 - Methods created via an attribute can now fulfill a "requires"
287 declaration for a role. (nothingmuch)
289 * Moose::Meta::Method::*
290 - Stack traces from inlined code will now report its line and
291 file as being in your class, as opposed to in Moose
294 0.64 Wed, December 31, 2008
295 * Moose::Meta::Method::Accessor
296 - Always inline predicate and clearer methods (Sartak)
298 * Moose::Meta::Attribute
299 - Support for parameterized traits (Sartak)
300 - verify_against_type_constraint method to avoid duplication
301 and enhance extensibility (Sartak)
304 - Tests (but no support yet) for parameterized traits (Sartak)
307 - Require Class::MOP 0.75+, which has the side effect of making
308 sure we work on Win32. (Dave Rolsky)
310 0.63 Mon, December 8, 2008
312 - Some small grammar tweaks and bug fixes in non-Moose example
315 0.62_02 Fri, December 5, 2008
316 * Moose::Meta::Role::Application::ToClass
317 - When a class does not provide all of a role's required
318 methods, the error thrown now mentions all of the missing
319 methods, as opposed to just the first one found. Requested by
320 Curtis Poe (RT #41119). (Dave Rolsky)
322 * Moose::Meta::Method::Constructor
323 - Moose will no longer inline a constructor for your class
324 unless it inherits its constructor from Moose::Object, and
325 will warn when it doesn't inline. If you want to force
326 inlining anyway, pass "replace_constructor => 1" to
327 make_immutable. Addresses RT #40968, reported by Jon
328 Swartz. (Dave Rolsky)
329 - The quoting of default values could be broken if the default
330 contained a single quote ('). Now we use quotemeta to escape
331 anything potentially dangerous in the defaults. (Dave Rolsky)
333 0.62_01 Wed, December 3, 2008
335 - use the method->execute API for BUILDALL
336 and DEMOLISHALL (Sartak)
338 * Moose::Util::TypeConstraints
339 - We now make all the type constraint meta classes immutable
340 before creating the default types provided by Moose. This
341 should make loading Moose a little faster. (Dave Rolsky)
343 0.62 Wed November 26, 2008
344 * Moose::Meta::Role::Application::ToClass
345 Moose::Meta::Role::Application::ToRole
346 - fixed issues where excluding and aliasing the
347 same methods for a single role did not work
348 right (worked just fine with multiple
350 - added test for this (stevan)
352 * Moose::Meta::Role::Application::RoleSummation
353 - fixed the error message when trying to compose
354 a role with a role it excludes (Sartak)
357 - Catch another case where recursion caused the value
358 of $CALLER to be stamped on (t0m)
359 - added test for this (t0m)
362 - Remove the make_immutable keyword, which has been
363 deprecated since April. It breaks metaclasses that
364 use Moose without no Moose (Sartak)
366 * Moose::Meta::Attribute
367 - Removing an attribute from a class now also removes delegation
368 (handles) methods installed for that attribute (t0m)
369 - added test for this (t0m)
371 * Moose::Meta::Method::Constructor
372 - An attribute with a default that looked like a number (but was
373 really a string) would accidentally be treated as a number
374 when the constructor was made immutable (perigrin)
375 - added test for this (perigrin)
378 - create method for constructing a role
380 - added test for this (Sartak)
381 - anonymous roles! (Sartak)
382 - added test for this (Sartak)
385 - more consistent error messages (Sartak)
387 * Moose::Cookbook::Roles::Recipe1
388 - attempt to explain why a role that just requires
389 methods is useful (Sartak)
391 0.61 Fri November 7, 2008
392 * Moose::Meta::Attribute
393 - When passing a role to handles, it will be loaded if necessary
397 - Method objects returned by get_method (and other methods)
398 Could end up being returned without an associated_metaclass
399 attribute. Removing get_method_map, which is provided by
400 Class::MOP::Class, fixed this. The Moose version did nothing
401 different from its parent except introduce a bug. (Dave Rolsky)
402 - added tests for this (jdv79)
405 - Added a $VERSION to all .pm files which didn't have one. Fixes
406 RT #40049, reported by Adam Kennedy. (Dave Rolsky)
408 * Moose::Cookbook::Basics::Recipe4
409 * Moose::Cookbook::Basics::Recipe6
410 - These files had spaces on the first line of the SYNOPSIS, as
411 opposed to a totally empty line. According to RT #40432, this
412 confuses POD parsers. (Dave Rolsky)
414 0.60 Fri October 24, 2008
416 - Passing "-traits" when loading Moose caused the Moose.pm
417 exports to be broken. Reported by t0m. (Dave Rolsky)
418 - Tests for this bug. (t0m)
421 - Change resolve_metaclass alias to use the new
422 load_first_existing_class function. This makes it a lot
423 simpler, and also around 5 times faster. (t0m)
424 - Add caching to resolve_metaclass_alias, which gives an order
425 of magnitude speedup to things which repeatedly call the
426 Moose::Meta::Attribute->does method, notably MooseX::Storage
429 * Moose::Util::TypeConstraint
430 - Put back the changes for parameterized constraints that
431 shouldn't have been removed in 0.59. We still cannot parse
432 them, but MooseX modules can create them in some other
433 way. See the 0.58 changes for more details. (jnapiorkowski)
434 - Changed the way subtypes are created so that the job is
435 delegated to a type constraint parent. This clears up some
436 hardcoded checking and should allow correct subtypes of
437 Moose::Meta::Type::Constraint. Don't rely on this new API too
438 much (create_child_type) because it may go away in the
439 future. (jnapiorkowski)
441 * Moose::Meta::TypeConstraint::Union
442 - Type constraint names are sorted as strings, not numbers.
445 * Moose::Meta::TypeConstraint::Parameterizable
446 - New parameterize method. This can be used as a factory method
447 to make a new type constraint with a given parameterized
448 type. (jnapiorkowski)
449 - added tests (jnapiorkowski)
451 0.59 Tue October 14, 2008
453 - Add abridged documentation for builder/default/initializer/
454 predicate, and link to more details sections in
455 Class::MOP::Attribute. (t0m)
457 * Moose::Util::TypeConstraints
458 - removed prototypes from all but the &-based stuff (mst)
460 * Moose::Util::TypeConstraints
461 - Creating a anonymous subtype with both a constraint and a
462 message failed with a very unhelpful error, but should just
463 work. Reported by t0m. (Dave Rolsky)
466 - Some tests that used Test::Warn if it was available failed
467 with older versions of Test::Warn. Reported by Fayland. (Dave
469 - Test firing behavior of triggers in relation to builder/default/
471 - Test behavior of equals/is_a_type_of/is_a_subtype_of for all
472 kinds of supported type. (t0m)
475 - In create(), do not pass "roles" option to the superclass
476 - added related test that creates an anon metaclass with
479 * Moose::Meta::TypeConstraint::Class
480 * Moose::Meta::TypeConstraint::Role
481 - Unify behavior of equals/is_a_type_of/is_a_subtype_of with
482 other types (as per change in 0.55_02). (t0m)
484 * Moose::Meta::TypeConstraint::Registry
485 - Fix warning when dealing with unknown type names (t0m)
487 * Moose::Util::TypeConstraints
488 - Reverted changes from 0.58 related to handle parameterized
489 types. This caused random failures on BSD and Win32 systems,
490 apparently related to the regex engine. This means that Moose
491 can no longer parse structured type constraints like
492 ArrayRef[Int,Int] or HashRef[name=>Str]. This will be
493 supported in a slightly different way via MooseX::Types some
494 time in the future. (Dave Rolsky)
496 0.58 Sat September 20, 2008
497 !! This release has an incompatible change regarding !!
498 !! how roles add methods to a class !!
500 * Roles and role application
501 ! Roles now add methods by calling add_method, not
502 alias_method. They make sure to always provide a method
503 object, which will be cloned internally. This means that it is
504 now possible to track the source of a method provided by a
505 role, and even follow its history through intermediate roles.
507 This means that methods added by a role now show up when
508 looking at a class's method list/map. (Dave Rolsky)
511 - From this release on, we'll try to maintain a list of
512 conflicting modules, and warn you if you have one
513 installed. For example, this release conflicts with ...
514 - MooseX::Singleton <= 0.11
515 - MooseX::Params::Validate <= 0.05
518 In general, we try to not break backwards compatibility for
519 most Moose users, but MooseX modules and other code which
520 extends Moose's metaclasses is often affected by very small
521 changes in the Moose internals.
523 * Moose::Meta::Method::Delegation
524 * Moose::Meta::Attribute
525 - Delegation methods now have their own method class. (Dave
528 * Moose::Meta::TypeConstraint::Parameterizable
529 - Added a new method 'parameterize' which is basically a factory
530 for the containing constraint. This makes it easier to create
531 new types of parameterized constraints. (jnapiorkowski)
533 * Moose::Meta::TypeConstraint::Union
534 - Changed the way Union types canonicalize their names to follow
535 the normalized TC naming rules, which means we strip all
536 whitespace. (jnapiorkowski)
538 * Moose::Util::TypeConstraints
539 - Parameter and Union args are now sorted, this makes Int|Str
540 the same constraint as Str|Int. (jnapiorkowski)
541 - Changes to the way Union types are parsed to more correctly
542 stringify their names. (jnapiorkowski)
543 - When creating a parameterized type, we now use the new
544 parameterize method. (jnapiorkowski)
545 - Incoming type constraint strings are now normalized to remove
546 all whitespace differences. (jnapiorkowski)
547 - Changed the way we parse type constraint strings so that we now
548 match TC[Int,Int,...] and TC[name=>Str] as parameterized type
549 constraints. This lays the foundation for more flexible type
550 constraint implementations.
552 * Tests and docs for all the above. (jnapiorkowski)
556 - Moose::Exporter will no longer remove a subroutine that the
557 exporting package re-exports. Moose re-exports the
558 Carp::confess function, among others. The reasoning is that we
559 cannot know whether you have also explicitly imported those
560 functions for your own use, so we err on the safe side and
561 always keep them. (Dave Rolsky)
562 - added tests for this (rafl)
565 - Changes to how we fix metaclass compatibility that are much
566 too complicated to go into. The summary is that Moose is much
567 less likely to complain about metaclass incompatibility
568 now. In particular, if two metaclasses differ because
569 Moose::Util::MetaRole was used on the two corresponding
570 classes, then the difference in roles is reconciled for the
571 subclass's metaclass. (Dave Rolsky)
572 - Squashed an warning in _process_attribute (thepler)
575 - throw exceptions (sooner) for invalid attribute names (thepler)
576 - added tests for this (thepler)
578 * Moose::Util::MetaRole
579 - If you explicitly set a constructor or destructor class for a
580 metaclass object, and then applied roles to the metaclass,
581 that explicitly set class would be lost and replaced with the
585 * Moose::Meta::Attribute
586 * Moose::Meta::Method
589 * Moose::Error::Default
590 * Moose::Error::Croak
591 * Moose::Error::Confess
592 - All instances of confess() changed to use overridable
593 C<throw_error> method. This method ultimately calls a class
594 constructor, and you can change the class being called. In
595 addition, errors now pass more information than just a string.
596 The default C<error_class> behaves like C<Carp::confess>, so
597 the behavior is not visibly different for end users.
599 0.57 Wed September 3, 2008
601 - A new bit of doc intended to introduce folks familiar with
602 "standard" Perl 5 OO to Moose concepts. (Dave Rolsky)
605 - Shows examples of two classes, each done first with and then
606 without Moose. This makes a nice parallel to
607 Moose::Intro. (Dave Rolsky)
609 * Moose::Util::TypeConstraints
610 - Fixed a bug in find_or_parse_type_constraint so that it
611 accepts a Moose::Meta::TypeConstraint object as the parent
612 type, not just a name (jnapiorkowski)
613 - added tests (jnapiorkowski)
616 - If Sub::Name was not present, unimporting failed to actually
617 remove some sugar subs, causing test failures (Dave Rolsky)
619 0.56 Mon September 1, 2008
620 For those not following the series of dev releases, there are
621 several major changes in this release of Moose.
622 ! Moose::init_meta should now be called as a method. See the
625 - Major performance improvements by nothingmuch.
627 - New modules for extension writers, Moose::Exporter and
628 Moose::Util::MetaRole by Dave Rolsky.
630 - Lots of doc improvements and additions, especially in the
635 * Removed all references to the experimental-but-no-longer-needed
636 Moose::Meta::Role::Application::ToMetaclassInstance.
638 * Require Class::MOP 0.65.
640 0.55_04 Sat August 30, 2008
641 * Moose::Util::MetaRole
642 * Moose::Cookbook::Extending::Recipe2
643 - This simplifies the application of roles to any meta class, as
644 well as the base object class. Reimplemented metaclass traits
645 using this module. (Dave Rolsky)
647 * Moose::Cookbook::Extending::Recipe1
648 - This a new recipe, an overview of various ways to write Moose
649 extensions (Dave Rolsky)
651 * Moose::Cookbook::Extending::Recipe3
652 * Moose::Cookbook::Extending::Recipe4
653 - These used to be Extending::Recipe1 and Extending::Recipe2,
656 0.55_03 Fri August 29, 2008
657 * No changes from 0.55_02 except increasing the Class::MOP
658 dependency to 0.64_07.
660 0.55_02 Fri August 29, 2008
661 * Makefile.PL and Moose.pm
662 - explicitly require Perl 5.8.0+ (Dave Rolsky)
664 * Moose::Util::TypeConstraints
665 - Fix warnings from find_type_constraint if the type is not
668 * Moose::Meta::TypeConstraint
669 - Predicate methods (equals/is_a_type_of/is_subtype_of) now
670 return false if the type you specify cannot be found in the
671 type registry, rather than throwing an unhelpful and
672 coincidental exception. (t0m).
673 - added docs & test for this (t0m)
675 * Moose::Meta::TypeConstraint::Registry
676 - add_type_constraint now throws an exception if a parameter is
678 - added docs & test for this (t0m)
680 * Moose::Cookbook::FAQ
681 - Added a faq entry on the difference between "role" and "trait"

697 or builder methods are coerced as required. (t0m)
698 - added test for this (t0m)
700 * Moose::Meta::Attribute

702 coerce the default value. The immutable code _did_
704 - added test for this (t0m)
707 - This is a new helper module for writing "Moose-alike"
708 modules. This should make the lives of MooseX module authors
709 much easier. (Dave Rolsky)

796 ... this is not my day today ...
798 * Moose::Meta::Attribute
799 - fixed legal_options_for_inheritance such that
800 clone_and_inherit options still works for
801 Class::MOP::Attribute objects and therefore
802 does not break MooseX::AttributeHelpers
805 0.53 Thurs. July 3, 2008
806 * Whoops, I guess I should run 'make manifest' before
807 actually releasing the module. No actual changes

847 * Moose::Meta::Role::Application::ToRole
848 - when RoleA did RoleB, and RoleA aliased a method from RoleB in
849 order to provide its own implementation, that method still got
850 added to the list of required methods for consumers of
851 RoleB. Now an aliased method is only added to the list of
852 required methods if the role doing the aliasing does not
853 provide its own implementation. See Recipe 11 for an example
854 of all this. (Dave Rolsky)
855 - added tests for this
857 * Moose::Meta::Method::Constructor

1399 - shortened some file names for better VMS support (RT #32381)
1401 0.33 Fri. Dec. 14, 2007
1402 !! Moose now loads 2 x faster !!
1403 !! with new Class::MOP 0.49 !!
1405 ++ new oose.pm module to make command line
1406 Moose-ness easier (see POD docs for more)
1408 * Moose::Meta::Class
1410 - several tweaks to take advantage of the
1411 new method map caching in Class::MOP
1413 * Moose::Meta::TypeConstraint::Parameterized

1418 HashRef for containers (sartak)
1419 - added tests for this
1421 * Moose::Meta::TypeCoercion
1422 - coercions will now create subtypes as needed
1423 so you can now add coercions to parameterized
1424 types without having to explictly define them
1425 - added tests for this
1427 * Moose::Meta::Method::Accessor
1428 - allow subclasses to decide whether we need
1429 to copy the value into a new variable (sartak)
1431 0.32 Tues. Dec. 4, 2007
1432 * Moose::Util::TypeConstraints
1433 - fixing how subtype aliases of unions work
1434 they should inherit the parent's coercion
1435 - added tests for this
1436 - you can now define multiple coercions on
1437 a single type at different times instead of
1438 having to do it all in one place
1439 - added tests for this
1441 * Moose::Meta::TypeConstraint
1442 - there is now a default constraint of sub { 1 }
1443 instead of Moose::Util::TypeConstraints setting
1446 * Moose::Meta::TypeCoercion
1447 * Moose::Meta::TypeCoercion::Union
1448 - added the &has_coercion_for_type and
1449 &add_type_coercions methods to support the
1450 new features above (although you cannot add
1451 more type coercions for Union types)
1453 0.31 Mon. Nov. 26, 2007
1454 * Moose::Meta::Attribute
1455 - made the +attr syntax handle extending types with
1456 parameters. So "has '+foo' => (isa => 'ArrayRef[Int]')"
1457 now works if the original foo is an ArrayRef.
1458 - added tests for this.
1459 - delegation now works even if the attribute does not
1460 have a reader method using the get_read_method_ref
1461 method from Class::MOP::Attribute.
1462 - added tests for this
1463 - added docs for this
1465 * Moose::Util::TypeConstraints
1466 - passing no "additional attribute info" to
1467 &find_or_create_type_constraint will no longer
1468 attempt to create an __ANON__ type for you,
1469 instead it will just return undef.
1470 - added docs for this
1472 0.30 Fri. Nov. 23, 2007

1484 with work correctly.
1485 - added tests for this
1488 - adding the link to Recipie 11 (written by Sartak)
1489 - adding test for SYNOPSIS code
1492 - New tests for builder bug. Upon instantiation, if an
1493 attribute had a builder, no value and was not lazy the
1494 builder default was not getting run, oops. (groditi)
1496 0.29 Tues. Nov. 13, 2007
1497 * Moose::Meta::Attribute

1527 * fixing some misc. bits in the docs that
1528 got mentioned on CPAN Forum & perlmonks
1531 - fixed how required methods are handled
1532 when they encounter overriden or modified
1533 methods from a class (thanks to confound).
1534 - added tests for this
1536 * Moose::Util::TypeConstraint
1537 - fixed the type notation parser so that
1538 the | always creates a union and so is
1539 no longer a valid type char (thanks to
1540 konobi, mugwump and #moose for working
1542 - added more tests for this
1544 0.26 Thurs. Sept. 27, 2007
1547 * Parameterized Types
1548 We now support parameterized collection types, such as:
1549 ArrayRef[Int] # array or integers
1550 HashRef[Object] # a hash with object values
1551 They can also be nested:
1552 ArrayRef[HashRef[RegexpRef]] # an array of hashes with regex values
1553 And work with the type unions as well:
1554 ArrayRef[Int | Str] # array of integers of strings
1556 * Better Framework Extendability
1557 Moose.pm is now "extendable" such that it is now much
1558 easier to extend the framework and add your own keywords
1559 and customizations. See the "EXTENDING AND EMBEDDING MOOSE"
1560 section of the Moose.pm docs.
1563 In an effort to begin documenting some of the various
1564 details of Moose as well as some common idioms, we have
1565 created Moose::Cookbook::Snacks as a place to find
1566 small (easily digestable) nuggets of Moose code.
1569 ~ Several doc updates/cleanup thanks to castaway ~
1571 - converted build system to use Module::Install instead of
1572 Module::Build (thanks to jrockway)
1575 - added all the meta classes to the immutable list and
1576 set it to inline the accessors

1602 - fixed issue with generated accessor code making
1603 assumptions about hash based classes (thanks to dexter)
1605 * Moose::Coookbook::Snacks
1606 - these are bits of documentation, not quite as big as
1607 Recipes but which have no clear place in the module docs.
1608 So they are Snacks! (horray for castaway++)
1610 * Moose::Cookbook::Recipe4
1611 - updated it to use the new ArrayRef[MyType] construct
1612 - updated the accompanying test as well
1614 +++ Major Refactor of the Type Constraint system +++
1615 +++ with new features added as well +++
1617 * Moose::Util::TypeConstraint
1618 - no longer uses package variable to keep track of
1619 the type constraints, now uses the an instance of
1620 Moose::Meta::TypeConstraint::Registry to do it
1621 - added more sophisticated type notation parsing
1623 - added tests for this
1625 * Moose::Meta::TypeConstraint
1626 - some minor adjustments to make subclassing easier
1627 - added the package_defined_in attribute so that we
1628 can track where the type constraints are created
1630 * Moose::Meta::TypeConstraint::Union
1631 - this is now been refactored to be a subclass of
1632 Moose::Meta::TypeConstraint
1634 * Moose::Meta::TypeCoercion::Union
1635 - this has been added to service the newly refactored
1636 Moose::Meta::TypeConstraint::Union and is itself
1637 a subclass of Moose::Meta::TypeCoercion
1639 * Moose::Meta::TypeConstraint::Parameterized

1651 (thanks to shlomif).
1653 * Moose::Meta::Attribute
1654 - required attributes now will no longer accept undef
1655 from the constructor, even if there is a default and lazy
1656 - added tests for this
1657 - default subroutines must return a value which passes the
1659 - added tests for this
1661 * Moose::Meta::Attribute
1662 * Moose::Meta::Method::Constructor
1663 * Moose::Meta::Method::Accessor
1664 - type-constraint tests now handle overloaded objects correctly

1693 - added tests for these
1695 0.24 Tues. July 3, 2007
1696 ~ Some doc updates/cleanup ~
1698 * Moose::Meta::Attribute
1699 - added support for roles to be given as parameters
1700 to the 'handles' option.
1701 - added tests and docs for this

1704 (but not changing the handles option)
1705 - added tests and docs for this
1708 - required methods are now fetched using find_method_by_name
1709 so that required methods can come from superclasses
1710 - adjusted tests for this
1712 0.23 Mon. June 18, 2007
1713 * Moose::Meta::Method::Constructor
1714 - fix inlined constructor for hierarchy with multiple BUILD methods (mst)

1720 the other side (perigrin)
1722 0.22 Thurs. May 31, 2007
1723 * Moose::Util::TypeConstraints
1724 - fix for prototype undeclared issue when Moose::Util::TypeConstraints
1725 loaded before consumers (e.g. Moose::Meta::Attribute) by predeclaring
1726 prototypes for functions
1727 - added the ClassName type constraint, this checks for strings
1728 which will respond true to ->isa(UNIVERSAL).

1738 - fix reader presedence bug in Moose::Meta::Attribute + tests
1741 - Foo->new(undef) now gets ignored, it is assumed you meant to pass
1742 a HASH-ref and missed. This produces better error messages then
1743 having it die cause undef is not a HASH.
1744 - added tests for this
1746 0.21 Thursday, May 2nd, 2007
1748 - added SUPER_SLOT and INNER_SLOT class hashes to support unimport
1749 - modified unimport to remove super and inner along with the rest

1761 where not handled correctly in roles
1762 - added tests for this
1764 * Moose::Meta::Class
1765 - fixed issue where extending metaclasses with
1766 roles would blow up. Thanks to Aankhen`` for
1767 finding this insidious error, and it's solution.
1769 ~~ lots of spelling and grammer fixes in the docs,
1770 many many thanks to rlb3 and Aankhen for these :)
1772 0.20 Friday, April 6th, 2007
1773 >> I messed up the SKIP logic in one test
1774 so this release is just to fix that.
1777 - 'has' now also accepts an ARRAY ref
1778 to create multiple attrs (see docs)
1779 (thanks to konobi for this)
1780 - added tests and docs
1782 0.19 Thurs. April 5th, 2007
1783 ~~ More documentation updates ~~
1785 * Moose::Util::TypeConstraints
1786 - 'type' now supports messages as well
1787 thanks to phaylon for finding this
1788 - added tests for this
1789 - added &list_all_type_constraints and
1790 &list_all_builtin_type_constraints
1791 functions to facilitate introspection.
1793 * Moose::Meta::Attribute
1794 - fixed regexp 'handles' declarations
1795 to build the list of delegated methods
1796 correctly (and not override important
1797 things like &new) thanks to ashleyb
1799 - added tests and docs for this
1800 - added the 'documentation' attributes
1801 so that you can actually document your
1802 attributes and inspect them through the
1804 - added tests and docs for this
1806 * Moose::Meta::Class
1807 - when loading custom attribute metaclasses
1808 it will first look in for the class in the
1809 Moose::Meta::Attribute::Custom::$name, and
1810 then default to just loading $name.
1811 - added tests and docs for this
1813 * Moose::Meta::TypeConstraint
1814 - type constraints now stringify to their names.
1815 - added test for this
1818 - added tests to assure we work with Module::Refresh
1819 - added stricter test skip logic in the Moose POOP
1820 test, ask Rob Kinyon why.
1821 - *cough* DBM::Deep 1.0 backwards compatibility sucks *cough* ;)
1823 0.18 Sat. March 10, 2007
1824 ~~ Many, many documentation updates ~~
1827 - We now use Class::MOP::load_class to
1829 - added tests to show types and subtypes
1830 working with Declare::Constraints::Simple
1831 and Test::Deep as constraint engines.
1834 !! You must have Class::MOP 0.37_001 !!
1835 !! for this developer release to work !!
1837 This release was primarily adding the immutable
1838 feature to Moose. An immutable class is one which
1839 you promise not to alter. When you set the class
1840 as immutable it will perform various bits of
1841 memoization and inline certain part of the code
1842 (constructors, destructors and accessors). This
1843 minimizes (and in some cases totally eliminates)
1844 one of Moose's biggest performance hits. This
1845 feature is not on by default, and is 100% optional.
1846 It has several configurable bits as well, so you
1847 can pick and choose to your specific needs.
1849 The changes involved in this were fairly wide and
1850 highly specific, but 100% backwards compatible, so
1851 I am not going to enumerate them here. If you are
1852 truely interested in what was changed, please do
1855 0.17 Tues. Nov. 14, 2006
1856 * Moose::Meta::Method::Accessor
1857 - bugfix for read-only accessors which
1858 are have a type constraint and lazy.
1859 Thanks to chansen for finding it.
1861 0.16 Tues. Nov. 14, 2006
1863 There are some speed improvements in this release,
1864 but they are only the begining, so stay tuned.
1867 - BUILDALL and DEMOLISHALL no longer get
1868 called unless they actually need to be.
1869 This gave us a signifigant speed boost
1870 for the cases when there is no BUILD or
1871 DEMOLISH method present.
1873 * Moose::Util::TypeConstraints
1874 * Moose::Meta::TypeConstraint
1875 - added an 'optimize_as' option to the
1876 type constraint, which allows for a
1877 hand optimized version of the type
1878 constraint to be used when possible.
1879 - Any internally created type constraints
1880 now provide an optimized version as well.
1882 0.15 Sun. Nov. 5, 2006
1884 This version of Moose *must* have Class::MOP 0.36 in order
1885 to work correctly. A number of small internal tweaks have
1886 been made in order to be compatible with that release.
1888 * Moose::Util::TypeConstraints
1889 - added &unimport so that you can clean out
1890 your class namespace of these exported
1893 * Moose::Meta::Class
1894 - fixed minor issue which occasionally
1895 comes up during global destruction
1897 - moved Moose::Meta::Method::Overriden into
1901 - moved Moose::Meta::Role::Method into
1904 * Moose::Meta::Attribute
1905 - changed how we do type checks so that
1906 we reduce the overall cost, but still
1909 - moved accessor generation methods to
1910 Moose::Meta::Method::Accessor to
1911 conform to the API changes from
1914 * Moose::Meta::TypeConstraint
1915 - changed how constraints are compiled
1916 so that we do less recursion and more
1917 iteration. This makes the type check
1919 - moved Moose::Meta::TypeConstraint::Union
1922 * Moose::Meta::Method::Accessor
1923 - created this from methods formerly found in
1924 Moose::Meta::Attribute
1926 * Moose::Meta::Role::Method
1927 - moved this from Moose::Meta::Role
1929 * Moose::Meta::Method::Overriden
1930 - moved this from Moose::Meta::Class
1932 * Moose::Meta::TypeConstraint::Union
1933 - moved this from Moose::Meta::TypeConstraint
1935 0.14 Mon. Oct. 9, 2006
1937 * Moose::Meta::Attribute
1938 - fixed lazy attributes which were not getting
1939 checked with the type constraint (thanks ashley)
1940 - added tests for this
1941 - removed the over-enthusiastic DWIMery of the
1942 automatic ArrayRef and HashRef defaults, it
1943 broke predicates in an ugly way.
1944 - removed tests for this
1946 0.13 Sat. Sept. 30, 2006
1948 This version of Moose *must* have Class::MOP 0.35 in order
1949 to work correctly. A number of small internal tweaks have
1950 been made in order to be compatible with that release.
1953 - Removed the use of UNIVERSAL::require to be a better
1954 symbol table citizen and remove a dependency
1955 (thanks Adam Kennedy)
1957 **~~ removed experimental & undocumented feature ~~**
1958 - commented out the 'method' and 'self' keywords, see the
1959 comments for more info.
1962 - added a FAQ and WTF files to document frequently
1963 asked questions and common problems
1965 * Moose::Util::TypeConstraints
1966 - added GlobRef and FileHandle type constraint
1967 - added tests for this
1969 * Moose::Meta::Attribute
1970 - if your attribute 'isa' ArrayRef of HashRef, and you have
1971 not explicitly set a default, then make the default DWIM.
1972 This will also work for subtypes of ArrayRef and HashRef
1974 - you can now auto-deref subtypes of ArrayRef or HashRef too.
1975 - new test added for this (thanks to ashley)
1978 - added basic support for runtime role composition
1979 but this is still *highly experimental*, so feedback
1980 is much appreciated :)
1981 - added tests for this
1983 * Moose::Meta::TypeConstraint
1984 - the type constraint now handles the coercion process
1985 through delegation, this is to support the coercion
1988 * Moose::Meta::TypeConstraint::Union
1989 - it is now possible for coercions to be performed
1991 - added tests for this (thanks to konobi)
1993 * Moose::Meta::TypeCoercion
1994 - properly capturing error when type constraint
1998 - Scalar::Util 1.18 is bad on Win32, so temporarily
1999 only require version 1.17 for Win32 and cygwin.
2000 (thanks Adam Kennedy)
2002 0.12 Sat. Sept. 1, 2006
2004 - Recipe5 (subtypes & coercion) has been written
2007 - fixed "bad meta" error message to be more descriptive
2008 - fixed &unimport to not remove the &inner and &super
2009 keywords because we need to localize them.
2010 - fixed number of spelling/grammer issues, thanks Theory :)
2012 **~~ experimental & undocumented feature ~~**
2013 - added the method and self keywords, they are basically
2014 just sugar, and they may not stay around.
2017 - added &dump method to easily Data::Dumper
2020 * Moose::Meta::TypeConstraint
2021 - added the &is_a_type_of method to check both the current
2022 and the subtype of a method (similar to &isa with classes)
2025 - this is now a subclass of Class::MOP::Module, and no longer
2026 creates the _role_meta ugliness of before.
2027 - fixed tests to reflect this change
2029 0.11 Wed. July 12, 2006
2031 - added an &unimport method to remove all the keywords
2032 that Moose will import, simply add 'no Moose' to the
2033 bottom of your class file.
2036 - fixed some test failures caused by a forgotten test
2039 0.10 Thurs. July 6, 2006
2041 - improved error message when loading modules so
2042 it is less confusing when you load a role.
2043 - added &calculate_all_roles method to
2044 Moose::Meta::Class and Moose::Meta::Role
2047 This module has been tested against Class::MOP 0.30
2048 but it does not yet utilize the optimizations
2049 it makes available. Stay tuned for that ;)
2051 0.09_03 Fri. June 23, 2006
2052 ++ DEVELOPER RELEASE ++
2054 - 'use strict' and 'use warnings' are no longer
2055 needed in Moose classes, Moose itself will
2056 turn them on for you.
2057 - added tests for this
2058 - moved code from exported subs to private methods
2059 in Moose::Meta::Class
2062 - as with Moose, strict and warnings are
2063 automatically turned on for you.

2067 - now handles an edge case for override errors
2068 - added tests for this
2069 - added some more edge case tests

2082 - cleaned up prototypes for the subs
2085 0.09_01 Fri. May 12, 2006
2086 ++ DEVELOPER RELEASE ++
2087 - This release works in combination with
2088 Class::MOP 0.29_01, it is a developer
2089 release because it uses the a new
2090 instance sub-protocol and a fairly
2091 complete Role implementation. It has
2092 not yet been optimized, so it slower
2093 the the previous CPAN version. This
2094 release also lacks good updated docs,
2095 the official release will have updated docs.
2098 - refactored the keyword exports
2099 - 'with' now checks Role validaity and
2100 accepts more than one Role at a time
2101 - 'extends' makes metaclass adjustments as
2102 needed to ensure metaclass compatibility
2105 - refactored the keyword exports
2106 - 'with' now checks Role validaity and
2107 accepts more than one Role at a time
2109 * Moose::Util::TypeConstraints
2110 - added the 'enum' keyword for simple
2111 string enumerations which can be used as
2113 - see example of usage in t/202_example.t
2116 - more careful checking of params to new()
2119 - much work done on the role composition
2120 - many new tests for conflict detection
2121 and composition edge cases
2122 - not enough documentation, I suggest
2123 looking at the tests
2125 * Moose::Meta::Instance
2126 - added new Instance metaclass to support
2127 the new Class::MOP instance protocol
2129 * Moose::Meta::Class
2130 - some small changes to support the new
2132 - some small additions to support Roles
2134 * Moose::Meta::Attribute
2135 - some improvements to the accessor generation code
2137 - some small changes to support the new
2139 - (still somewhat) experimental delegation support
2140 with the 'handles' option
2141 - added several tests for this
2142 - no docs for this yet
2144 0.05 Thurs. April 27, 2006
2146 - keywords are now exported with Sub::Exporter
2147 thanks to chansen for this commit
2148 - has keyword now takes a 'metaclass' option
2149 to support custom attribute meta-classes
2150 on a per-attribute basis
2151 - added tests for this
2152 - the 'has' keyword not accepts inherited slot
2153 specifications (has '+foo'). This is still an
2154 experimental feature and probably not finished
2155 see t/038_attribute_inherited_slot_specs.t for
2156 more details, or ask about it on #moose
