2.3.2

This is a security fix release for the 2.3.x release branch.

• Security advisory: GHSA-m2qf-hxjv-5gpq, CVE-2023-30861
• Changes: https://flask.palletsprojects.com/en/2.3.x/changes/#version-2-3-2
• Milestone: https://github.com/pallets/flask/milestone/29?closed=1

2.3.1

• Changes: https://flask.palletsprojects.com/en/2.3.x/changes/#version-2-3-1
• Milestone: https://github.com/pallets/flask/milestone/28?closed=1

2.3.0

This is a feature release, which includes new features, removes previously deprecated code, and adds new deprecations. The 2.3.x branch is now the supported fix branch, the 2.2.x branch will become a tag marking the end of support for that branch. 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.

@maskit points out that now that the use of httpbin has been replaced by go-httpbin, and flask was pinned for httpbin, that we can probably just remove this item from the Pipfile. That sounds correct. I'm trying that here:
#9688

If all the tests pass for #9688, then we should simply close this PR in favor of the latter.

I'm closing this in favor of simply removing the flask dependency entirely:
#9688

[dependabot]

OK, I won't notify you again about this release, but will get in touch when a new version is available. If you'd rather skip all updates until the next major or minor version, let me know by commenting @dependabot ignore this major version or @dependabot ignore this minor version.

If you change your mind, just re-open this PR and I'll resolve any conflicts on it.
