- **fixed** — Fixed a bug where `DagsterInstance.get_latest_materialization_event` and `get_asset_records` could return a stale pre-wipe materialization for a wiped asset once a new run targeting the asset started or an observation was reported
- **fixed** — Fixed a bug in Dagster+ where wiping partitions could leave the wiped partition's materialization as the asset's latest materialization
- **fixed** — Fixed an issue where an asset backfill could get stuck emitting no further runs but never completing when an asset whose partitions definition includes certain dates depended on an asset whose partitions definition excludes them
- **fixed** — Fixed a performance issue where assets partitioned by a cron schedule using an explicit minute list computed partition counts much more slowly than the equivalent `*/30` schedule
- **changed** — Improved the performance of loading the backfills for a partition set on deployments with a large number of backfills
- **fixed** — Fixed a performance regression in the UI that caused views with truncated text such as the asset catalog to render slowly
- **fixed** — Fixed an issue where importing `dagster_cloud.serverless` could fail with a missing `boto3` dependency on serverless deployments that did not install the `[serverless]` extra

###### Bugfixes

- Fixed a bug where `DagsterInstance.get_latest_materialization_event` (and `get_asset_records`) could return a stale pre-wipe materialization for a wiped asset once a new run targeting the asset started or an observation was reported. In Dagster+, fixed the analogous bug where wiping partitions could leave the wiped partition's materialization as the asset's latest materialization.
- Fixed an issue where an asset backfill could get stuck — emitting no further runs but never completing — when an asset whose partitions definition includes certain dates depended on an asset whose partitions definition excludes them.
- Fixed a performance issue where assets partitioned by a cron schedule using an explicit minute list (e.g. `0,30 * * * *`) computed partition counts much more slowly than the equivalent `*/30` schedule.
- Improved the performance of loading the backfills for a partition set on deployments with a large number of backfills, which previously fetched and deserialized every backfill in the deployment on each request.
- [ui] Fixed a performance regression that caused views with truncated text, such as the asset catalog, to render slowly.
- [dagster-cloud] Fixed an issue where importing `dagster_cloud.serverless` could fail with a missing `boto3` dependency on serverless deployments that did not install the `[serverless]` extra.
