05:14 AM Feature #22011: Hash tables with swiss table
- I see that the benchmarks might be affected, since st_numhash/symbol hash path looks like returning constant 128 on bits 25..31, which increases the hash collision, under investigating.

05:13 AM Bug #22013: Array#| deduplication via eql? breaks when total element count exceeds ~16
- Is this a document issue?

- Bumps the github-actions group with 1 update in the / directory: [taiki-e/install-action](https://github.com/taiki-e/install-action).
Updates `taiki-e/install-action` from 2.75.19 to 2.75.20

12:44 AM Revision 11e0e7cc (git): [ruby/rubygems] Point recovery instructions at bundle pristine under Bundler

no_install_plugin is set needs a Bundler-native equivalent. Override

11:49 PM Revision fd9cee5f (git): [ruby/prism] Fix incompatibilities for `on_word_sep` in ripper

10:48 PM Feature #22011: Hash tables with swiss table
- Just a side note, enlarging `struct st_table` by 16B as some consequence for various objects sizes (e.g. Hash goes from pool 80 to pool 96, but a bunch of other structs embed `struct st_table`).

03:01 PM Feature #22012: Data class should respond to #dig

12:18 PM Feature #22012 (Open): Data class should respond to #dig

the type of the local variables because we don't mutate the strings. - 02:24 AM Revision f6b0f318 (git): Bump the github-actions group across 1 directory with 2 updates
