Airflow 2.9.1 (2024-05-03)
--------------------------
Significant Changes
^^^^^^^^^^^^^^^^^^^
Stackdriver logging bugfix requires Google provider ``10.17.0`` or later (#38071)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
If you use Stackdriver logging, you must use Google provider version ``10.17.0`` or later. Airflow ``2.9.1`` now passes ``gcp_log_name`` to the ``StackdriverTaskHandler`` instead of ``name``, and this will fail on earlier provider versions.
This fixes a bug where the log name configured in ``[logging] remove_base_log_folder`` was overridden when Airflow configured logging, resulting in task logs going to the wrong destination.
Bug Fixes
"""""""""
- Make task log messages include run_id (#39280)
- Copy menu_item ``href`` for nav bar (#39282)

- Check whether ``AUTH_ROLE_PUBLIC`` is set in ``check_authentication`` (#39012)
- Move rendering of ``map_index_template`` so it renders for failed tasks as long as it was defined before the point of failure (#38902)
- ``Undeprecate`` ``BaseXCom.get_one`` method for now (#38991)
- Add ``inherit_cache`` attribute for ``CreateTableAs`` custom SA Clause (#38985)

- Fix ``SAWarning`` 'Coercing Subquery object into a select() for use in IN()' (#38926)
- Fix implicit ``cartesian`` product in AirflowSecurityManagerV2 (#38913)

- Fix dag run link params (#38873)
- Use async db calls in WorkflowTrigger (#38689)
- Fix audit log events filter (#38719)

Airflow 2.9.0 (2024-04-08)
--------------------------
Significant Changes
^^^^^^^^^^^^^^^^^^^
Following Listener API methods are considered stable and can be used for production system (were experimental feature in older Airflow versions) (#36376):
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Lifecycle events:
- ``on_starting``
- ``before_stopping``
DagRun State Change Events:
- ``on_dag_run_running``
- ``on_dag_run_success``
- ``on_dag_run_failed``
TaskInstance State Change Events:
- ``on_task_instance_running``
- ``on_task_instance_success``
- ``on_task_instance_failed``
Support for Microsoft SQL-Server for Airflow Meta Database has been removed (#36514)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
After `discussion <https://lists.apache.org/thread/r06j306hldg03g2my1pd4nyjxg78b3h4>`__
and a `voting process <https://lists.apache.org/thread/pgcgmhf6560k8jbsmz8nlyoxosvltph2>`__,
the Airflow's PMC and Committers have reached a resolution to no longer maintain MsSQL as a supported Database Backend.
As of Airflow 2.9.0 support of MsSQL has been removed for Airflow Database Backend.
A migration script which can help migrating the database *before* upgrading to Airflow 2.9.0 is available in
`airflow-mssql-migration repo on Github <https://github.com/apache/airflow-mssql-migration>`_.
Note that the migration script is provided without support and warranty.
This does not affect the existing provider packages (operators and hooks), DAGs can still access and process data from MsSQL.
Dataset URIs are now validated on input (#37005)
""""""""""""""""""""""""""""""""""""""""""""""""
Datasets must use a URI that conform to rules laid down in AIP-60, and the value
will be automatically normalized when the DAG file is parsed. See
`documentation on Datasets <https://airflow.apache.org/docs/apache-airflow/stable/authoring-and-scheduling/datasets.html>`_ for
a more detailed description on the rules.
You may need to change your Dataset identifiers if they look like a URI, but are
used in a less mainstream way, such as relying on the URI's auth section, or
have a case-sensitive protocol name.
The method ``get_permitted_menu_items`` in ``BaseAuthManager`` has been renamed ``filter_permitted_menu_items`` (#37627)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Add REST API actions to Audit Log events (#37734)
"""""""""""""""""""""""""""""""""""""""""""""""""
The Audit Log ``event`` name for REST API events will be prepended with ``api.`` or ``ui.``, depending on if it came from the Airflow UI or externally.
Official support for Python 3.12 (#38025)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
There are a few caveats though:
* Pendulum2 does not support Python 3.12. For Python 3.12 you need to use
`Pendulum 3 <https://pendulum.eustace.io/blog/announcing-pendulum-3-0-0.html>`_
* Minimum SQLAlchemy version supported when Pandas is installed for Python 3.12 is ``1.4.36`` released in
April 2022. Airflow 2.9.0 increases the minimum supported version of SQLAlchemy to ``1.4.36`` for all
Python versions.
Not all Providers support Python 3.12. At the initial release of Airflow 2.9.0 the following providers
are released without support for Python 3.12:
* ``apache.beam`` - pending on `Apache Beam support for 3.12 <https://github.com/apache/beam/issues/29149>`_
* ``papermill`` - pending on Releasing Python 3.12 compatible papermill client version
`including this merged issue <https://github.com/nteract/papermill/pull/771>`_
Prevent large string objects from being stored in the Rendered Template Fields (#38094)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
There's now a limit to the length of data that can be stored in the Rendered Template Fields.
The limit is set to 4096 characters. If the data exceeds this limit, it will be truncated. You can change this limit
by setting the ``[core]max_template_field_length`` configuration option in your airflow config.
Change xcom table column value type to longblob for MySQL backend (#38401)
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Xcom table column ``value`` type has changed from ``blob`` to ``longblob``. This will allow you to store relatively big data in Xcom but process can take a significant amount of time if you have a lot of large data stored in Xcom.
To downgrade from revision: ``b4078ac230a1``, ensure that you don't have Xcom values larger than 65,535 bytes. Otherwise, you'll need to clean those rows or run ``airflow db clean xcom`` to clean the Xcom table.
Stronger validation for key parameter defaults in taskflow context variables (#38015)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
As for the taskflow implementation in conjunction with context variable defaults invalid parameter orders can be
generated, it is now not accepted anymore (and validated) that taskflow functions are defined with defaults
other than ``None``. If you have done this before you most likely will see a broken DAG and a error message like
``Error message: Context key parameter my_param can't have a default other than None``.

Airflow 2.8.2 (2024-02-26)
--------------------------
Significant Changes
^^^^^^^^^^^^^^^^^^^
The ``allowed_deserialization_classes`` flag now follows a glob pattern (#36147).
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
For example if one wants to add the class ``airflow.tests.custom_class`` to the
``allowed_deserialization_classes`` list, it can be done by writing the full class
name (``airflow.tests.custom_class``) or a pattern such as the ones used in glob
search (e.g., ``airflow.*``, ``airflow.tests.*``).
If you currently use a custom regexp path make sure to rewrite it as a glob pattern.
Alternatively, if you still wish to match it as a regexp pattern, add it under the new
list ``allowed_deserialization_classes_regexp`` instead.
The audit_logs permissions have been updated for heightened security (#37501).
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
This was done under the policy that we do not want users like Viewer, Ops,
and other users apart from Admin to have access to audit_logs. The intention behind
this change is to restrict users with less permissions from viewing user details
like First Name, Email etc. from the audit_logs when they are not permitted to.
The impact of this change is that the existing users with non admin rights won't be able
to view or access the audit_logs, both from the Browse tab or from the DAG run.
``AirflowTimeoutError`` is no longer ``except`` by default through ``Exception`` (#35653).
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
The ``AirflowTimeoutError`` is now inheriting ``BaseException`` instead of
``AirflowException``->``Exception``.
See https://docs.python.org/3/library/exceptions.html#exception-hierarchy
This prevents code catching ``Exception`` from accidentally
catching ``AirflowTimeoutError`` and continuing to run.
``AirflowTimeoutError`` is an explicit intent to cancel the task, and should not
be caught in attempts to handle the error and return some default value.
Catching ``AirflowTimeoutError`` is still possible by explicitly ``except``ing
``AirflowTimeoutError`` or ``BaseException``.
This is discouraged, as it may allow the code to continue running even after
such cancellation requests.
Code that previously depended on performing strict cleanup in every situation
after catching ``Exception`` is advised to use ``finally`` blocks or
context managers. To perform only the cleanup and then automatically
re-raise the exception.

https://docs.python.org/3/library/exceptions.html#KeyboardInterrupt

Airflow 2.8.1 (2024-01-19)
--------------------------
Significant Changes
^^^^^^^^^^^^^^^^^^^
Target version for core dependency ``pendulum`` package set to 3 (#36281).
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
Support for pendulum 2.1.2 will be saved for a while, presumably until the next feature version of Airflow.
It is advised to upgrade user code to use pendulum 3 as soon as possible.
Pendulum 3 introduced some subtle incompatibilities that you might rely on in your code - for example
default rendering of dates is missing ``T`` in the rendered date representation, which is not ISO8601
compliant. If you rely on the default rendering of dates, you might need to adjust your code to use
``isoformat()`` method to render dates in ISO8601 format.
Airflow packaging specification follows modern Python packaging standards (#36537).
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
We standardized Airflow dependency configuration to follow latest development in Python packaging by
using ``pyproject.toml``. Airflow is now compliant with those accepted PEPs:
* `PEP-440 Version Identification and Dependency Specification <https://www.python.org/dev/peps/pep-0440/>`__
* `PEP-517 A build-system independent format for source trees <https://www.python.org/dev/peps/pep-0517/>`__

This has almost no noticeable impact on users if they are using modern Python packaging and development tools, generally
speaking Airflow should behave as it did before when installing it from PyPI and it should be much easier to install
it for development purposes using ``pip install -e ".[devel]"``.
The differences from the user side are:
* Airflow extras now get extras normalized to ``-`` (following PEP-685) instead of ``_`` and ``.``
(as it was before in some extras). When you install airflow with such extras (for example ``dbt.core`` or
``all_dbs``) you should use ``-`` instead of ``_`` and ``.``.
In most modern tools this will work in backwards-compatible way, but in some old version of those tools you might need to
replace ``_`` and ``.`` with ``-``. You can also get warnings that the extra you are installing does not exist - but usually
this warning is harmless and the extra is installed anyway. It is, however, recommended to change to use ``-`` in extras in your dependency
specifications for all Airflow extras.
* Released airflow package does not contain ``devel``, ``devel-*``, ``doc`` and ``doc-gen`` extras.
Those extras are only available when you install Airflow from sources in ``--editable`` mode. This is
because those extras are only used for development and documentation building purposes and are not needed
when you install Airflow for production use. Those dependencies had unspecified and varying behaviour for
released packages anyway and you were not supposed to use them in released packages.
* The ``all`` and ``all-*`` extras were not always working correctly when installing Airflow using constraints
because they were also considered as development-only dependencies. With this change, those dependencies are
now properly handling constraints and they will install properly with constraints, pulling the right set
of providers and dependencies when constraints are used.
Graphviz dependency is now an optional one, not required one (#36647).
""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
The ``graphviz`` dependency has been problematic as Airflow required dependency - especially for
ARM-based installations. Graphviz packages require binary graphviz libraries - which is already a
limitation, but they also require to install graphviz Python bindings to be build and installed.
This does not work for older Linux installation but - more importantly - when you try to install
Graphviz libraries for Python 3.8, 3.9 for ARM M1 MacBooks, the packages fail to install because
Python bindings compilation for M1 can only work for Python 3.10+.
This is not a breaking change technically - the CLIs to render the DAGs is still there and IF you
already have graphviz installed, it will continue working as it did before. The only problem when it
does not work is where you do not have graphviz installed it will raise an error and inform that you need it.
Graphviz will remain to be installed for most users:
* the Airflow Image will still contain graphviz library, because
it is added there as extra
* when previous version of Airflow has been installed already, then
graphviz library is already installed there and Airflow will
continue working as it did
The only change will be a new installation of new version of Airflow from the scratch, where graphviz will
need to be specified as extra or installed separately in order to enable DAG rendering option.

Airflow 2.8.0 (2023-12-18)
--------------------------
Significant Changes
^^^^^^^^^^^^^^^^^^^
Raw HTML code in DAG docs and DAG params descriptions is disabled by default (#35460)
"""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""""
To ensure that no malicious javascript can be injected with DAG descriptions or trigger UI forms by DAG authors
a new parameter ``webserver.allow_raw_html_descriptions`` was added with default value of ``False``.
If you trust your DAG authors code and want to allow using raw HTML in DAG descriptions and params, you can restore the previous
behavior by setting the configuration value to ``True``.
To ensure Airflow is secure by default, the raw HTML support in trigger UI has been super-seeded by markdown support via
the ``description_md`` attribute. If you have been using ``description_html`` please migrate to ``description_md``.
The ``custom_html_form`` is now deprecated.
