The second major theme is an architectural refactor of App Router rendering, led by Zack Tanner across roughly ten linked pull requests. The work replaces an implicit "static generation" flag with an explicit execution mode, then goes further to fully separate request-time rendering from prerendering as distinct…
A third theme is infrastructure and release plumbing. PR 96860 relocated the last actively-used Turbopack benchmarking package into the main packages directory after its publish pipeline silently broke, with a lint follow-up in 96871.
