VIP MU plugins v20261013.0 # VIP MU plugins v20261013.0 --- 13 October 2026 18:43:30 GMT+0000 [ VIP MU plugins [Production] ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/) [ GitHub ](https://github.com/Automattic/vip-go-mu-plugins/pull/7403) [ Permalink ](https://docs.wpvip.com/changelog/vip-mu-plugins-production/vip-mu-plugins-v20261013-0/) View Pull Request: [https://github.com/Automattic/vip-go-mu-plugins/pull/7403](https://github.com/Automattic/vip-go-mu-plugins/pull/7403) ### Fixed * Fixed support-form delivery through mail providers that require a verified sender. * Added server-side support-form mail failure diagnostics with common sensitive values redacted. * Fixed resetting the support form after a successful submission. * Fixed `bin/test.sh` so the test runner always finds the project’s `vendor/` directory, regardless of the `wp-test-runner` image’s home directory. * None. This changes tests only. * VIP Feed Cache: Fixed cached feeds never being read back on WordPress 6.7+, which caused a remote request on every `fetch_feed()` call. * Real-Time Collaboration: Kept undo and redo working for entities excluded from collaboration when the same editor loaded synchronized entities. * Enterprise Search: Fixed nested meta query groups with named clauses being dropped, which could return unfiltered results. * N/A: test-only change. ### Changed * VIP Search: Slow-query warnings now compare the Elasticsearch execution time (` took`) against `vip_search_slow_query_threshold_ms` instead of the total HTTP request duration, so network and connection overhead outside Elasticsearch no longer triggers warnings. Requests that are slow end-to-end while transferring at least 1 MiB of data still warn, with guidance to request fewer results or fields. * VIP Search: The human-readable slow and unbounded query warnings are now prefixed with `VIP_SEARCH_QUERY_WARNING:` to make them easier to find in application logs. * None. This changes tests only. * Real-Time Collaboration: Updated the collaborator avatar stack focus ring to use the editor design system outline.
