 # Prefect Release Notes
 
+## Release 2.10.10
+
+### The need for (CLI & import) speed
+
+We wanted the CLI to be as fast as the rest of Prefect. Through a series of enhancements, we've sped up CLI performance by as much as 4x on some systems! See the following pull requests for more information on how we sped up the CLI prefect import:
+- Delay `apprise` imports — https://github.com/PrefectHQ/prefect/pull/9557
+- Defer import of `dateparser` — https://github.com/PrefectHQ/prefect/pull/9582
+- Defer loading of Prefect integrations until necessary — https://github.com/PrefectHQ/prefect/pull/9571
+- Add `Block.get_block_class_from_key` and replace external uses of `lookup_type` — https://github.com/PrefectHQ/prefect/pull/9621
+
+### Enhancements
+- Handle `SIGTERM` received by workers gracefully — https://github.com/PrefectHQ/prefect/pull/9530
+- Add ability to view table artifacts with NaN values in the Prefect UI — https://github.com/PrefectHQ/prefect/pull/9585
+- Update `prefect version` command to avoid creating the database if it does not exist — https://github.com/PrefectHQ/prefect/pull/9586
+- Allow client retries when server SQLite database is busy — https://github.com/PrefectHQ/prefect/pull/9632
+
+### Fixes

+- Fix deadlock when logging is overriden from an asynchronous context — https://github.com/PrefectHQ/prefect/pull/9602
+- Fix orchestration race conditions by adding lock for update to flow run state transitions — https://github.com/PrefectHQ/prefect/pull/9590
+- Fix date range filter on flow runs page — https://github.com/PrefectHQ/prefect/pull/9636
+
+### Documentation
+- Clarify the retry on tasks concept page — https://github.com/PrefectHQ/prefect/pull/9560
+- Improve the navigation structure and clarity of the API docs — https://github.com/PrefectHQ/prefect/pull/9574
+- Add `work_pool_name` to `Deployment.build_from_flow` on deployments concept page — https://github.com/PrefectHQ/prefect/pull/9581
+- Add additional worker types to work pools, workers & agents concept page — https://github.com/PrefectHQ/prefect/pull/9580
