 ### Added
 
+- Added support for ConfigMap reference-based queryables configuration in addition to file-based queryables. Queryables can now be sourced from external ConfigMaps using `configMapRef`, from chart files using `file`, or a combination of both [#360](https://github.com/developmentseed/eoapi-k8s/pull/360)

 ### Added
 
 - Exposed PgSTAC configuration options in Helm chart values (`pgstacBootstrap.settings.pgstacSettings`). These are dynamically applied via templated SQL during bootstrap. [#340](https://github.com/developmentseed/eoapi-k8s/pull/340)
-  - Added `queue_timeout`, `use_queue`, and `update_collection_extent` settings for database performance tuning
+- Added `queue_timeout`, `use_queue`, and `update_collection_extent` settings for database performance tuning
   - Made existing context settings configurable (`context`, `context_estimated_count`, `context_estimated_cost`, `context_stats_ttl`)
   - Automatic queue processor CronJob created when `use_queue` is "true" (configurable schedule via `queueProcessor.schedule`)
   - Automatic extent updater CronJob created when `update_collection_extent` is "false" (configurable schedule via `extentUpdater.schedule`)
