The clearest signal in today's activity is Rails preparing its internals for Ractors, Ruby's actor-based concurrency model. Three merges tackled this from different angles. Ryuta Kamizono's PR 58460 gave Active Support Notifications a formal protocol, so custom notification targets no longer have to mimic the…
The second theme is a cleanup pass through Active Record's attribute methods, driven mostly by Hartley McGuire. PR 58462 removed an unbounded cache used to speed up dynamic respond-to checks, because it didn't work with Ractors and had no size limit. That trade-off cost some performance, so PR 58466 restored it with…
Elsewhere, two data-correctness fixes stand out: PR 58446 fixes queries using column-tuple syntax that reference another table's columns, and PR 58465 addresses null owner keys on composite belongs-to associations. Both were silent correctness bugs, not crashes.
On the smaller side, PR 58461 lets you lock down ffmpeg and ffprobe arguments for Active Storage, closing a real hardening gap in media processing. And PR 58473 fixes a variant transformation ordering bug that could cause duplicate blobs…
