Breaking Changes
Git Plugin: Default Branch Name Changed
The default branch within Git tasks has been renamed from kestra to main (PR #98). Make sure to update any workflows that implicitly rely on the former default branch.
Secrets: Exception Thrown on Missing Secret
Fetching a non-existing secret using the secret() function now throws an exception instead of returning null, aligning the open-source behavior with the behavior in the Enterprise Edition (PR #6495).
Change State: Restart Downstream Task Runs
Manually changing a task run's status from Failed to a non-failed state (e.g. Success) via the Change state interface now restarts all downstream task runs, including subflows (PR #6799).
Restarting Parent Flow with Failed Subflow
When restarting an execution, Subflow or ForEachItem tasks now restart the existing failed subflow execution rather than creating a new one. This behavior is configurable via the new restartBehavior enum property; setting it to NEW_EXECUTION retains the previous behavior (PR #6799; Issue #6722). A system.restarted: true label is added during restart for tracking, and the underlying subflow execution storage table is retained to avoid migration issues (scheduled for removal in v0.22).
Script Tasks: STDERR Logged at ERROR Level
Script tasks now log output sent to stderr at the ERROR level instead of WARNING (PR #6383; Issue #190).
Flows Created Before v0.9: Redeployment Required
Flows created before v0.9 and not updated since require editing or redeployment due to changes in source auto-generation (PR #6264).
