3.1.3

This is the Flask 3.1.3 security fix release, which fixes a security issue but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.3/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-3

• The session is marked as accessed for operations that only access the keys but not the values, such as in and len. GHSA-68rp-wp8r-4726

3.1.2

This is the Flask 3.1.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.2/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-2 Milestone: https://github.com/pallets/flask/milestone/38?closed=1

• stream_with_context does not fail inside async views. #5774
• When using follow_redirects in the test client, the final state of session is correct. #5786
• Relax type hint for passing bytes IO to send_file. #5776

3.1.1

This is the Flask 3.1.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.1/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-1 Milestone https://github.com/pallets/flask/milestone/36?closed=1

• Fix signing key selection order when key rotation is enabled via SECRET_KEY_FALLBACKS. GHSA-4grg-w6v8-c28g
• Fix type hint for cli_runner.invoke. #5645
• flask --help loads the app and plugins first to make sure all commands are shown. #5673
• Mark sans-io base class as being able to handle views that return AsyncIterable. This is not accurate for Flask, but makes typing easier for Quart. #5659

3.1.0

This is the Flask 3.1.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecations, or introduce potentially breaking changes. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

PyPI: https://pypi.org/project/Flask/3.1.0/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-0 Milestone: https://github.com/pallets/flask/milestone/33?closed=1

• Drop support for Python 3.8. #5623
• Update minimum dependency versions to latest feature releases. Werkzeug >= 3.1, ItsDangerous >= 2.2, Blinker >= 1.9. #5624, #5633
• Provide a configuration option to control automatic option responses. #5496
• Flask.open_resource/open_instance_resource and Blueprint.open_resource take an encoding parameter to use when opening in text mode. It defaults to utf-8. #5504
• Request.max_content_length can be customized per-request instead of only through the MAX_CONTENT_LENGTH config. Added MAX_FORM_MEMORY_SIZE and MAX_FORM_PARTS config. Added documentation about resource limits to the security page. #5625
• Add support for the Partitioned cookie attribute (CHIPS), with the SESSION_COOKIE_PARTITIONED config. #5472
• -e path takes precedence over default .env and .flaskenv files. load_dotenv loads default files in addition to a path unless load_defaults=False is passed. #5628
• Support key rotation with the SECRET_KEY_FALLBACKS config, a list of old secret keys that can still be used for unsigning. Extensions will need to add support. #5621
• Fix how setting host_matching=True or subdomain_matching=False interacts with SERVER_NAME. Setting SERVER_NAME no longer restricts requests to only that domain. #5553
• Request.trusted_hosts is checked during routing, and can be set through the TRUSTED_HOSTS config. #5636

Apache Airflow 3.1.8

:package: PyPI: https://pypi.org/project/apache-airflow/3.1.8/ :books: Docs: https://airflow.apache.org/docs/apache-airflow/3.1.8/ :hammer_and_wrench: Release Notes: https://airflow.apache.org/docs/apache-airflow/3.1.8/release_notes.html :whale: Docker Image: "docker pull apache/airflow:3.1.8" :busstop: Constraints: https://github.com/apache/airflow/tree/constraints-3.1.8

Significant Changes

Backfill permissions are now handled via DagAccessEntity.Run (#61456)

is_authorized_backfill of the BaseAuthManager interface has been removed. Core will no longer call this method and their provider counterpart implementation will be marked as deprecated. Permissions for backfill operations are now checked against the DagAccessEntity.Run permission using the existing requires_access_dag decorator. In other words, if a user has permission to run a DAG, they can perform backfill operations on it.

Please update your security policies to ensure that users who need to perform backfill operations have the appropriate DagAccessEntity.Run permissions. (Users having the Backfill permissions without having the DagRun ones will no longer be able to perform backfill operations without any update)

Elasticsearch is now fully compatible with remote logging along (#62940)

Elasticsearch is now fully compatible with remote logging along side with apache-airflow-providers-elasticsearch>=6.5.0. Please review elasticsearch provider release notes for more information https://airflow.apache.org/docs/apache-airflow-providers-elasticsearch/6.5.0/changelog.html (#62121) (#62940)

Dockerfile Changelog

The Dockerfile does not strictly follow the SemVer <https://semver.org/>_ approach of Apache Airflow when it comes to features and backwards compatibility. While Airflow code strictly follows it, the Dockerfile is really a way to give users a conveniently packaged Airflow using standard container approach, so occasionally there are some changes in the building process or in the entrypoint of the image that require slight adaptation of how it is used or built.

The Changelog below describes the changes introduced in each version of the docker images released by the Airflow team.

:note: The Changelog below concerns only the convenience production images released at Airflow DockerHub <https://hub.docker.com/r/apache/airflow>_ . The images that are released there are usually built using the Dockerfile released together with Airflow. However, you are free to take latest released Dockerfile from Airflow and use it to build an image for any Airflow version from the Airflow 2 line. There is no guarantee that it will work, but if it does, then you can use latest features from that image to build images for previous Airflow versions.

Airflow 3.1.4

In Airflow 3.1.4, the images are build without removing of .pyc and .pyo files when Python is built.
This increases the size of the image slightly (<0.5%), but improves performance of Python in the container
because Python does not need to recompile the files on the first run but more importantly, if you use
``exec`` to run Health Checks, removed .pyc files caused a small but ever growing memory leak in the Unix
kernel connected to negative ``dentries`` created when .pyc files were attempted to be compiled and failed.
This over time could lead to out-of-memory issues on the host running the container.
More information about dentries can be found in this article &lt;https://lwn.net/Articles/814535/&gt;_.

3.1.3

This is the Flask 3.1.3 security fix release, which fixes a security issue but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.3/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-3

• The session is marked as accessed for operations that only access the keys but not the values, such as in and len. GHSA-68rp-wp8r-4726

3.1.2

This is the Flask 3.1.2 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.2/ Changes: https://flask.palletsprojects.com/page/changes/#version-3-1-2 Milestone: https://github.com/pallets/flask/milestone/38?closed=1

• stream_with_context does not fail inside async views. #5774
• When using follow_redirects in the test client, the final state of session is correct. #5786
• Relax type hint for passing bytes IO to send_file. #5776

3.1.1

This is the Flask 3.1.1 fix release, which fixes bugs but does not otherwise change behavior and should not result in breaking changes compared to the latest feature release.

PyPI: https://pypi.org/project/Flask/3.1.1/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-1 Milestone https://github.com/pallets/flask/milestone/36?closed=1

• Fix signing key selection order when key rotation is enabled via SECRET_KEY_FALLBACKS. GHSA-4grg-w6v8-c28g
• Fix type hint for cli_runner.invoke. #5645
• flask --help loads the app and plugins first to make sure all commands are shown. #5673
• Mark sans-io base class as being able to handle views that return AsyncIterable. This is not accurate for Flask, but makes typing easier for Quart. #5659

3.1.0

This is the Flask 3.1.0 feature release. A feature release may include new features, remove previously deprecated code, add new deprecations, or introduce potentially breaking changes. We encourage everyone to upgrade, and to use a tool such as pip-tools to pin all dependencies and control upgrades. Test with warnings treated as errors to be able to adapt to deprecation warnings early.

PyPI: https://pypi.org/project/Flask/3.1.0/ Changes: https://flask.palletsprojects.com/en/stable/changes/#version-3-1-0 Milestone: https://github.com/pallets/flask/milestone/33?closed=1

• Drop support for Python 3.8. #5623
• Update minimum dependency versions to latest feature releases. Werkzeug >= 3.1, ItsDangerous >= 2.2, Blinker >= 1.9. #5624, #5633
• Provide a configuration option to control automatic option responses. #5496
• Flask.open_resource/open_instance_resource and Blueprint.open_resource take an encoding parameter to use when opening in text mode. It defaults to utf-8. #5504
• Request.max_content_length can be customized per-request instead of only through the MAX_CONTENT_LENGTH config. Added MAX_FORM_MEMORY_SIZE and MAX_FORM_PARTS config. Added documentation about resource limits to the security page. #5625
• Add support for the Partitioned cookie attribute (CHIPS), with the SESSION_COOKIE_PARTITIONED config. #5472
• -e path takes precedence over default .env and .flaskenv files. load_dotenv loads default files in addition to a path unless load_defaults=False is passed. #5628
• Support key rotation with the SECRET_KEY_FALLBACKS config, a list of old secret keys that can still be used for unsigning. Extensions will need to add support. #5621
• Fix how setting host_matching=True or subdomain_matching=False interacts with SERVER_NAME. Setting SERVER_NAME no longer restricts requests to only that domain. #5553
• Request.trusted_hosts is checked during routing, and can be set through the TRUSTED_HOSTS config. #5636
