- (@todo docs) Added `record.ExpandedOne(rel)` and `record.ExpandedAll(rel)` helpers to retrieve casted single or multiple expand relations from the already loaded "expand" Record data.
## v0.16.10
- Added multiple valued fields (`relation`, `select`, `file`) normalizations to ensure that the zero-default value of a newly created multiple field is applied for already existing data ([#2930](https://github.com/pocketbase/pocketbase/issues/2930)).
## v0.16.9
- Register the `eagerRequestDataCache` middleware only for the internal `api` group routes to avoid conflicts with custom route handlers ([#2914](https://github.com/pocketbase/pocketbase/issues/2914)).
