4.0.0
TL;DR: This release includes a ton of improvements from 2.5 years of development! 🎉 Test thoroughly after switching.
For more than two years, there was no major release of python-can.
However, development was very much active over most of this time, and many parts were switched out and improved.
Over this time, over 530 issues and PRs have been resolved or merged, and discussions took place in even more.
Statistics of the final diff: About 200 files changed due to ~22k additions and ~7k deletions from more than thirty contributors.
This changelog diligently lists the major changes but does not promise to be the complete list of changes.
Therefore, users are strongly advised to thoroughly test their programs against this new version.
Re-reading the documentation for your interfaces might be helpful too as limitations and capabilities might have changed or are more explicit.
While we did try to avoid breaking changes, in some cases it was not feasible and in particular, many implementation details have changed.
A massive thank you to Felix Divo for preparing this release, and to the many many contributors.
