 # Changelog
 
+# 1.6.3 (core) / 0.22.3 (libraries)
+
+### New
+
+- Added support for the 3.0 release of the `pendulum` library, for Python versions 3.9 and higher.
+- Performance improvements when starting run worker processes or step worker processes for runs in code locations with a large number of jobs.
+- `AllPartitionMapping` now supports mapping to downstream partitions, enabling asset backfills with these dependencies. Thanks [@craustin](https://github.com/craustin)!
+- [asset checks][experimental] `@asset_check` has new fields `additional_deps` and `additional_ins` to allow dependencies on assets other than the asset being checked.
+- [ui] Asset graph group nodes now show status counts.
+  - [dagster-snowflake] The Snowflake I/O Manager now has more specific error handling when a table doesn’t exist.
+- [ui] [experimental] A new experimental UI for the auto-materialize history of a specific asset has been added. This view can be enabled under your user settings by setting “Use new asset auto-materialize history page”.
+- [ui] Command clicking on an asset group will now select or deselect all assets in that group.
+- [dagster-k8s] Added the ability to customize resource limits for initContainers used by Dagster system components in the Dagster Helm chart. Thanks **[@MattyKuzyk](https://github.com/MattyKuzyk)**!
+- [dagster-k8s] Added the ability to specify additional containers and initContainers in code locations in the Helm chart. Thanks **[@craustin](https://github.com/craustin)**!
+- [dagster-k8s] Explicitly listed the set of RBAC permissions used by the agent Helm chart role instead of using a wildcard. Thanks **[@easontm](https://github.com/easontm)**!
+- [dagster-dbt] Support for `dbt-core==1.4.*` is now removed because [the version has reached end-of-life](https://docs.getdbt.com/docs/dbt-versions/core).
+
+### Bugfixes
+
+- Previously, calling `get_partition_keys_not_in_subset` on a `BaseTimeWindowPartitionsSubset` that targeted a partitions definition with no partitions (e.g. a future start date) would raise an error. Now, it returns an empty list.
+- Fixed issue which could cause invalid runs to be launched if a code location was updated during the course of an AMP evaluation.
+- Previously, some asset backfills raised an error when targeting multi-assets with internal asset dependencies. This has been fixed.
+- Previously, using the `LocalComputeLogManager` on Windows could result in errors relating to invalid paths. This has been resolved. Thanks **[@hainenber](https://github.com/hainenber)**!
+- An outdated path in the contribution guide has been updated. Thanks **[@hainenber](https://github.com/hainenber)**!
+- [ui] Previously an error was sometimes raised when attempting to create a dynamic partition within a multi-partitioned asset via the UI. This has been fixed.
+- [ui] The “Upstream materializations are missing” warning when launching a run has been expanded to warn about failed upstream materializations as well.
+- [ui] The community welcome modal now renders properly in dark mode and some elements of Asset and Op graphs have higher contrast in both themes.
+- [ui] Fixed dark mode colors for datepicker, error message, and op definition elements.
+- [ui] Pressing the arrow keys to navigate op/asset graphs while the layout is loading no longer causes errors.
+- [ui] Exporting asset and op graphs to SVG no longer fails when chrome extensions inject additional stylesheets into Dagster’s UI.
+- [ui] Dagster now defaults to UTC when the user’s default timezone cannot be identified, rather than crashing with a date formatting error.
+- [ui] Fixed an issue in the asset graph sidebar that caused groups to only list their first asset.
+- [ui] Fixed an issue where sensors runs would undercount the number of dynamic partition requests added or deleted if there were multiple requests for additions/deletions.
+- [docs] Fixed a typo in the “Using Dagster with Delta Lake” guide. Thanks **[@avriiil](https://github.com/avriiil)!**
+- [asset checks] Fixed an issue which could cause errors when using asset checks with step launchers.
+- [dagster-webserver] A bug preventing WebSocket connections from establishing on python 3.11+ has been fixed.
+- [dagster-databricks] `DatabricksJobRunner` now ensures the correct`databricks-sdk` is installed. Thanks **[@zyd14](https://github.com/zyd14)**!
+- [dagster-dbt] On run termination, an interrupt signal is now correctly forwarded to any in-progress dbt subprocesses.
+- [dagster-dbt] Descriptions for dbt tests ingested as asset checks can now be populated using the `config.meta.description`. Thanks **[@CapitanHeMo](https://github.com/CapitanHeMo)**!
+- [dagster-dbt] Previously, the error message displayed when no dbt profiles information was found would display an incorrect path. This has been fixed. Thanks **[@zoltanctoth](https://github.com/zoltanctoth)**!
+- [dagster-k8s] `PipesK8sClient` can now correctly handle `load_incluster_config` . Thanks **[@aignas](https://github.com/aignas)**!
+
+### Documentation
+
+- Added a new category to **Concepts:** [Automation](https://docs.dagster.io/concepts/automation)**.** This page provides a high-level overview of the various ways Dagster allows you run data pipelines without manual intervention.
+- Moved several concept pages under **Concepts > Automation**: Schedules, Sensors, Asset Sensors, and Auto-materialize Policies.
+
+### Dagster Cloud
+
+- Fixed an issue where configuring the `agent_queue` key in a `dagster_cloud.yaml` file incorrectly failed to validate when using the `dagster-cloud ci init` or `dagster-cloud ci check` commands during CI/CD.
