Update bundled gems list as of 2025-12-12

use ractor_sched_lock

instead of using rb_native_mutex_lock directly.

Binding#local_variable_defined? raises a NameError for numbered params.

[Bug #21776]

Win32: Make rb_w32_osid return Windows NT always

Since support for Windows 9x was dropped over a decade ago.

Win32: Deprecate Windows version info API

dwMajorVersion alone has no meaning since Windows 7. Use API in
VersionHelper.h instead.

Win32: Remove the workaround for console reading bug

It has been fixed at Windows 8, and we already have dropped the
support Windows 8 and olders.

Binding#local_variable_defined? must not handle numbered parameters

[Bug #21776]

release.yml: Fix tag conversion for Ruby 4.0

and PREVIOUS_RELEASE_TAG for any .0 releases

tool/format-release: Fix a wrong method reference

tool/format-release: Carve out the version format logic

to share it with tool/releng/update-www-meta.rb and another place I'm
going to modify next.

make-snapshot: Fix Psych::DisallowedClass with newer psych

$ tool/format-release ../www.ruby-lang.org 4.0.0-preview2 .
/opt/rubies/3.4.6/lib/ruby/3.4.0/psych/class_loader.rb:99:in 'Psych::ClassLoader::Restricted#find': Tried to load unspecified class: Date (Psych::DisallowedClass)...

ZJIT: Don't specialize calls with kwsplat (#15513)

make-snapshot: Update the tag format for Ruby 4.0+ (#15514)

make-snapshot: Remove an unnecessary variable

This is a refactoring change, which should have no impact on behaviors.

Now, if patchlevel is true, tag is empty. So if patchlevel always does
nothing. Given that prerelease is false and tag is not nil, removing...

make-snapshot: Branch if it's X.Y.Z or X.Y using when

It just seems like a completely different input, so it makes more sense
to me to have it as a separate case.

Also, we don't need to support Ruby 2.0 or older.

make-snapshot: Make preview/rc match stricter

to make it a bit more consistent with the other branch

make-snapshot: Drop X.Y.Z-pN support

We no longer make patchlevel releases.

update-www-meta.rb: Update the tag format for Ruby 4.0+

Just copied format-release fixes in
a973526c050fec044ffd7ceeba0ac8e8a1fed299 to this file.

tool/merger.rb: Support the new format in remove_tag

monitor.c: skip GET_EC() on exit

tool/format-release: Fix the tag format for Ruby 4.0+

tool/merger.rb: Update the tag format for Ruby 4.0+

test_ractor.rb: old object while calling _id2ref

Mutex: avoid repeated calls to GET_EC

That call is surprisingly expensive, so trying doing it once
in #synchronize and then passing the EC to lock and unlock
saves quite a few cycles.

Tune AS_CASE indentation style and remove [*] for default case

There are many indentation styles for AS_CASE in this file but no one
uses [*] for the default case.

[ruby/timeout] Skip signal test on windows

Windows has no SIGUSR1.

There might be another usable signal, but this is breaking ruby master
so I just want a quick fix for now.

Stop bumping RUBY_PATCHLEVEL in release versions (#15502)

[Misc #21770]

Add assumption to free_vm_weak_references

Help the compiler know that we always get a heap object here.

Speed up class allocator search

This rewrites the class allocator search to be faster. Instead of using
RCLASS_SUPER, which is now even slower due to Box, we can scan the
superclasses list to find a class where the allocator is defined.

This also disallows allocating from an ICLASS. Previously I believe that...

Assume result from allocator will be valid

This adds a fastpath in class_call_alloc_func to simply return if the
class matches the one expected.

I think we could probably just remove this check, or move it to the debug
build.
