+Airflow 2.11.1 (2026-02-20)
+---------------------------
+
+Significant Changes
+^^^^^^^^^^^^^^^^^^^
+
+Python 3.9 support removed
+""""""""""""""""""""""""""
+
+Support for Python 3.9 has been removed, as it has reached end-of-life.
+Airflow 2.11.1 requires Python 3.10, 3.11, or 3.12. Note that this is unusual
to remove
+Python version support in patch-level release of Airflow, but since Python 3.9
is already
+end-of-life, many libraries do not support it any more, and Airflow 2.11.1 is
focused on
+improving security by upgrading dependencies, so we decided to remove Python
3.9 support
+in this patch release, to improve security of the release. Python 3.10 and
3.11 had almost
+no backward-incompatible changes, so you should be able to upgrade to Python
3.10 or 3.11
+easily. If you were using Python 3.9 before, it is recommended to first
upgrade Python version
+in existing installation and then upgrade to Airflow 2.11.1.
+
+Publishing timer and timing metrics in seconds is now deprecated
+""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+In Airflow 3.0, the ``timer_unit_consistency`` setting in the ``metrics``
section will be
+enabled by default and setting itself will be removed. This will standardize
all timer and timing metrics to
+milliseconds across all metric loggers.
+
+**Users Integrating with Datadog, OpenTelemetry, or other metric backends**
should enable this setting. For users, using
+``statsd``, this change will not affect you.
+
+If you need backward compatibility, you can leave this setting disabled
temporarily, but enabling
+``timer_unit_consistency`` is encouraged to future-proof your metrics setup.
(#39908)
+
+Retrieving historical log templates is disabled in Airflow 2.11.1
+"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
+
+When you change the log template in Airflow 2.11.1, the historical log
templates are not retrieved.
+This means that if you have existing logs that were generated using a
different log template,
+they will not be accessible using the new log template.
+
+This change is due to potential security issues that could arise from
retrieving historical log templates,
+which allow Dag Authors to execute arbitrary code in webserver when retrieving
logs.
+By disabling the retrieval of historical log templates, Airflow 2.11.1 aims to
enhance the security of the
+system and prevent potential vulnerabilities in case the potential of
executing arbitrary code in webserver
+is important for Airflow deployment.
+
+Users who need to access historical logs generated with a different log
template will need to manually
+update their log files to match the naming of their historical log files with
the latest log template
+configured in Airflow configuration, or they can set the
"core.use_historical_filename_templates"
+configuration option to True to enable the retrieval of historical log
templates, if they are fine with
+the Dag Authors being able to execute arbitrary code in webserver when
retrieving logs. (#61880)
+
+Updated dependencies
+""""""""""""""""""""
+
+Airflow 2.11.1 includes updates to a number of dependencies including
connexion, Flask-Session, Werkzeug,
+that were not possible to upgrade before, because the dependencies did not
have compatible versions
+with Airflow 2.11.0, but we worked together with the community to update them.
Many thanks to connexion
+team and a number of community members to help with the updates so that we
could upgrade to newer
+versions and get rid of some dependency versions that had known security
vulnerabilities (#51681)
