The thread today is preventing quiet breakage, with a secondary effort to trim unnecessary work and clarify operations.
First, query and media handling get more reliable. Pull request 59386, now merged, keeps table-scoped optimizer hints on the inner query when counting with limits or distinct on MySQL, instead of moving everything outward where table hints could be silently ignored. That means index hints keep working and counts…
Second, less wasted work. Pull request 59385 converts Journey's HTTP verb matchers to static definitions so they cache better with Bootsnap instead of regenerating on every boot. Pull request 59389 avoids building the full query tree just to check ordering in the in-batches method when returning an enumerator,…
