Good morning, it's Friday, October 24th, 2026, and here's what's moving in Ruby on Rails.
The big picture is consolidation: documentation is standardizing on Markdown, while core hot paths are getting leaner through repeated allocation and boot-time fixes.
First, Markdown is now the default for API docs. In pull request 59339, the docs generator was switched to Markdown, removing the need for per-file markup tags. Follow-up conversions covered the Action Mailer, Action View, and Action Pack readmes, with related commits migrating Active Storage, Action Mailbox, and…
Second, a steady performance push is cutting temporary objects in request handling. Pull request 59316 trims string and pattern work when building HTTP web addresses for plain hosts, with a measurable speed-up on resource URL helpers. Related work in pull request 59329 cuts overhead when filtering route parameters.…

Pull request 59325 rebuilds deprecation proxies on Basic Object so forwarding stays…
