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.

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

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

dnspython 2.6.1

See What's New for details.

This is a bug fix release for 2.6.0 where the "TuDoor" fix erroneously suppressed legitimate Truncated exceptions. This caused the stub resolver to timeout instead of failing over to TCP when a legitimate truncated response was received over UDP.

This release addresses the potential DoS issue discussed in the "TuDoor" paper (CVE-2023-29483). The dnspython stub resolver is vulnerable to a potential DoS if a bad-in-some-way response from the right address and port forged by an attacker arrives before a legitimate one on the UDP port dnspython is using for that query. In this situation, dnspython might switch to querying another resolver or give up entirely, possibly denying service for that resolution. This release addresses the issue by adopting the recommended mitigation, which is ignoring the bad packets and continuing to listen for a legitimate response until the timeout for the query has expired.

Thank you to all the contributors to this release, and, as usual, thanks to my co-maintainers: Tomáš Křížek, Petr Špaček, and Brian Wellington.

Sourced from dnspython's changelog.

2.6.1

• The Tudoor fix ate legitimate Truncated exceptions, preventing the resolver from failing over to TCP and causing the query to timeout #1053.

2.6.0

• As mentioned in the "TuDoor" paper and the associated CVE-2023-29483, the dnspython stub resolver is vulnerable to a potential DoS if a bad-in-some-way response from the right address and port forged by an attacker arrives before a legitimate one on the UDP port dnspython is using for that query.

  This release addresses the issue by adopting the recommended mitigation, which is ignoring the bad packets and continuing to listen for a legitimate response until the timeout for the query has expired.

• Added support for the NSID EDNS option.

• Dnspython now looks for version metadata for optional packages and will not use them if they are too old. This prevents possible exceptions when a feature like DoH is not desired in dnspython, but an old httpx is installed along with dnspython for some other purpose.

• The DoHNameserver class now allows GET to be used instead of the default POST, and also passes source and source_port correctly to the underlying query methods.

2.5.0

• Dnspython now uses hatchling for builds.

• Asynchronous destinationless sockets now work on Windows.

• Cython is no longer supported due to various typing issues.

• Dnspython now explicitly canonicalizes IPv4 and IPv6 addresses. Previously it was possible for non-canonical IPv6 forms to be stored in a AAAA address, which would work correctly but possibly cause problmes if the address were used as a key in a dictionary.

• The number of messages in a section can be retrieved with section_count().

• Truncation preferences for messages can be specified.

• The length of a message can be automatically prepended when rendering.

6.1.0 (2026-04-17)

This release fixes a possible external entity injection (XXE) vulnerability in iterparse() and the ETCompatXMLParser.

Features added

• GH#486: The HTML ARIA accessibility attributes were added to the set of safe attributes in lxml.html.defs. This allows lxml_html_clean to pass them through. Patch by oomsveta.

• The default chunk size for reading from file-likes in iterparse() is now configurable with a new chunk_size argument.

Bugs fixed

• LP#2146291: The resolve_entities option was still set to True for iterparse and ETCompatXMLParser, allowing for external entity injection (XXE) when using these parsers without setting this option explicitly. The default was now changed to 'internal' only (as for the normal XML and HTML parsers since lxml 5.0). Issue found by Sihao Qiu as CVE-2026-41066.

• LP#2125399: Some failing tests were fixed or disabled in PyPy.
