Good morning, it's Thursday, October 15th, 2026.
The throughline today is less work per request, and fewer wrong answers from complex associations.
First, per-request overhead. Pull request 59054 short-circuits routing for static paths, so index, new, and health-check routes skip full pattern simulation. Pull request 59053 cuts filesystem checks for static files, probing the top-level public entry before building candidates. And pull request 59056 avoids…
Second, association correctness, largely around composite keys. Pull request 59075 fixes empty tuple queries that produced invalid SQL, polymorphic queries against composite targets, and preloading that ignored available records. Pull request 59074 stops matching through-associations by direct keys, which could…
Finally, background jobs and database reliability. Pull request 58979 makes rescue-from, retry-on and discard-on work outside the main Ractor, and 58975 stops retries from mutating the original deserialized job data. For Postgres, 59069 fixes sequence resets on schema-qualified tables, and 58948 applies the table…
