In pylint 2.15.0, we added a new check missing-timeout
to warn of default timeout values that could cause a program to be hanging indefinitely.
We improved pylint
's handling of namespace packages. More packages should be linted without resorting to using the --recursive=y
option.
We still welcome any community effort to help review, integrate, and add good/bad examples to the doc for <#5953>_. This should be doable without any pylint or astroid knowledge, so this is the perfect entrypoint if you want to contribute to pylint` or open source without any experience with our code!
Internally, we changed the way we generate the release notes, thanks to DudeNr33. There will be no more conflict resolution to do in the changelog, and every contributor rejoice.
Marc Byrne became a maintainer, welcome to the team !
