01:02 AM Ruby Revision 2cdfc0d2 (git): [Bug #22420] Prefix `lib/` only to collected files of default gems

The files collected for a default gem are relative to its lib
directory, while the files listed by the gemspec itself are relative
to the gem root. `load_gemspec` prefixed `lib/` to any `.rb` entry
missing from the current directory, so ... ksss (Yuki Kurihara)

01:02 AM Ruby Revision 6b32bb45 (git): Evaluate gemspecs in a binding without local variables

Gemspecs can assign local variables such as `files`, `file` and
`base`, which overwrote the ones of `load_gemspec`. For instance,

of their specs pointed to their Ruby ... ksss (Yuki Kurihara)

03:03 PM Ruby Revision 2e236bfd (git): [ruby/prism] Declare `pp` dependency of RBS signatures in `sig/manifest.yaml`

The generated RBS files refer to `PP` in `pretty_print: (PP q) -> void`,

02:55 AM Ruby Bug #22420 (Closed): `require "strscan"` no longer activates the default gem, so a newer installed strscan is ignored and later loaded twice

Since Ruby 4.0.0, `require "strscan"` loads the default version from rubylibdir even when a newer strscan gem is installed, and does not activate the default gem. If the gem is activated later, its extension is loaded on top of the one a... ksss (Yuki Kurihara)

02:33 PM Ruby Feature #21020: Sync sig directory for prism of default gem.

Sorry for the late reply. I'd like to resume the discussion.
I'd like to install the signatures into the gem directory of each default gem, as @Eregon suggested in #note-3:

05:39 AM Ruby Feature #22081: Core type definition migration from `ruby/rbs` to `ruby/ruby`

The `ruby/rbs` repository consists of type definitions that are loaded by default (`core`) and those that can be loaded optionally (`stdlib`).
* Could you please clarify the scope of the type definitions to be migrated? For instance, ... ksss (Yuki Kurihara)
