Amazon MWAA adds support for Apache Airflow 2.11.2
The managed Airflow service picks up a maintenance release carrying security patches, bug fixes, and provider updates for S3 and CloudWatch.
Does Amazon MWAA support Apache Airflow 2.11.2?
Yes. As of July 24, 2026, Amazon Managed Workflows for Apache Airflow (MWAA) supports Airflow 2.11.2. The update is available in all regions where MWAA currently operates, and both new and existing environments can be moved to the new version.
What changed in Airflow 2.11.2?
Airflow 2.11.2 is a maintenance release rather than a feature drop. Its primary focus is shoring up security and reliability rather than introducing new capabilities.
The release upgrades core dependencies with security patches and brings stability improvements to both the webserver and the task execution layers. Teams running large pipelines should also note a fix to task lifecycle management for queued tasks, which addresses edge cases in how tasks transition through states.
On the operational side, secrets masking in logs has been enhanced, reducing the risk of sensitive values surfacing in Airflow's log output. The Task Instances list view in the UI received corrections as well, which should make monitoring task state more reliable day-to-day.
Provider package updates round out the release, specifically for S3 and CloudWatch log delivery. Both are common integration points for MWAA users who store DAG artifacts in S3 or route Airflow logs to CloudWatch, so those fixes are likely to matter to a broad slice of the managed-service user base.
How do you upgrade?
Existing MWAA environments can be upgraded through the AWS Management Console without infrastructure changes. AWS positions the upgrade as a few-click operation, consistent with how previous version bumps have been handled on the service.
For teams creating net-new environments, 2.11.2 is available as a selectable version at environment creation time across all supported MWAA regions.
Should you upgrade now?
Because 2.11.2 is a maintenance release with security patches, there is a practical argument for upgrading sooner rather than later, particularly for environments that handle sensitive data or run in regulated contexts. The secrets-masking improvement and the dependency security patches are the most directly security-relevant changes noted in the announcement.
The task lifecycle fix for queued tasks is worth evaluating for pipelines that have exhibited stuck or incorrectly-reported task states, though the announcement does not specify which queued-task scenarios are addressed.
