Frequently Asked Questions

When is Flake8 released?

Flake8 is released as necessary. Sometimes there are specific goals and drives to get to a release. Usually, we release as users report and fix bugs.

How can I help Flake8 release faster?

Look at the next milestone. If there’s work you can help us complete, that will help us get to the next milestone. If there’s a show-stopping bug that needs to be released, let us know but please be kind. Flake8 is developed and released entirely on volunteer time.

What is the next version of Flake8?

In general we try to use milestones to indicate this. If the last release on PyPI is 3.1.5 and you see a milestone for 3.2.0 in GitHub, there’s a good chance that 3.2.0 is the next release.

Why does Flake8 use ranges for its dependencies?

Flake8 uses ranges for mccabe, pyflakes, and pycodestyle because each of those projects tend to add new checks in minor releases. It has been an implicit design goal of Flake8’s to make the list of error codes stable in its own minor releases. That way if you install something from the 2.5 series today, you will not find new checks in the same series in a month from now when you install it again.

Flake8’s dependencies tend to avoid new checks in patch versions which is why Flake8 expresses its dependencies roughly as:

pycodestyle >= 2.0.0, < 2.1.0
pyflakes >= 0.8.0, != 1.2.0, != 1.2.1, != 1.2.2, < 1.3.0
mccabe >= 0.5.0, < 0.6.0

This allows those projects to release patch versions that fix bugs and for Flake8 users to consume those fixes.

Should I file an issue when a new version of a dependency is available?

No. The current Flake8 core team (of one person) is also a core developer of pycodestyle, pyflakes, and mccabe. They are aware of these releases.
