+BUG FIXES:
+
+* cli: Fix a bug in the `var put` command which prevented combining items as CLI arguments and other parameters as flags [[GH-19423](https://github.com/hashicorp/nomad/issues/19423)]
+* client: remove incomplete allocation entries from client state database during client restarts [[GH-16638](https://github.com/hashicorp/nomad/issues/16638)]
+* connect: Fixed a bug where deployments would not wait for Connect sidecar task health checks to pass [[GH-19334](https://github.com/hashicorp/nomad/issues/19334)]
+* consul: uses token namespace to fetch policies for verification [[GH-18516](https://github.com/hashicorp/nomad/issues/18516)]
+* csi: Added validation to `csi_plugin` blocks to prevent `stage_publish_base_dir` from being a subdirectory of `mount_dir` [[GH-19441](https://github.com/hashicorp/nomad/issues/19441)]
+* metrics: Revert upgrade of `go-metrics` to fix an issue where metrics from dependencies, such as raft, were no longer emitted [[GH-19376](https://github.com/hashicorp/nomad/issues/19376)]
