@ -76,6 +76,12 @@
- Allowed `0` as `RelationOptions.MinSelect` value to avoid the ambiguity between 0 and non-filled input value ([#2817](https://github.com/pocketbase/pocketbase/discussions/2817)).
## v0.16.7
- Minor optimization for the list/search queries to use `rowid` with the `COUNT` statement when available.
_This eliminates the temp B-TREE step when executing the query and for large datasets (eg. 150k) it could have 10x improvement (from ~580ms to ~60ms)._
## v0.16.6
- Fixed collection index column sort normalization in the Admin UI ([#2681](https://github.com/pocketbase/pocketbase/pull/2681); thanks @SimonLoir).
