11:59 PM Ruby Bug #22508 (Open): `Resolv.new(use_ipv6: ...)` is silently ignored since resolv 0.6.0 (Ruby 3.4): Since resolv 0.6.0 (bundled with Ruby 3.4.0), the `use_ipv6:` keyword argument of `Resolv.new` is silently ignored when no positional argument is given. In resolv 0.3.0 (Ruby 3.3) it set `use_ipv6` of the DNS resolver. Is this intended?

01:44 PM Ruby Revision c31e1506 (git): tool/run-lcov.rb: Exclude bundled gems from coverage aggregation: Since a1efb9ae6b (Promote prism to a bundled gem), the prism extension

04:59 AM Ruby Bug #22427 (Closed): `--enable=zjit` does not enable ZJIT: `ruby --help` lists `zjit` under "Features" (`zjit Method-based JIT compiler (default: disabled).`), but `--enable=zjit` alone does not enable ZJIT, while `--enable=yjit` does enable YJIT.
