Release Highlights
This release does not includes any schema changes.
Notable changes
Expose Closed status of Temporal Cron Workflow Executions and Workflow Executions that retry
Previously Temporal Cron Workflow Executions and Workflow Executions that retried always ended with a "Continued-As-New" status, now they have a final event like any other, with a "Completed" or "Failed" or "Timed out" status. If you have code that depends on the "Continued-As-New" status you'll need to update it.
Custom search attributes changes
String search attribute type was renamed to Text to better reflect its nature and match Elasticsearch type. String is still supported as deprecated alias to Text and will be removed.
Visibility changes
Many small improvements and bug fixes in visibility.
The docker container now runs as a non-root user
You should make sure you're using https://github.com/temporalio/helm-charts/releases/tag/v1.13.0 which contains a corresponding change to the Kubernetes securityContext.
Dynamic config validator
If dynamic config is malformed an error message will be written to the log. In the next version, a malformed dynamic config will prevent the server from starting. If you see error message about dynamic config, please fix it.
SQLite persistence
Many thanks to Jacob LeGrone (DataDog) for his contribution of the SQLite driver (#1968, #2029). NOTE: The SQLite driver is still under development.

Bug fixes
