We follow calendar versioning. Therefore, we only support the latest version.
Nevertheless, you should not be afraid to upgrade if you only use our documented public APIs and pay attention to deprecation warnings.
Whenever compatibility needs to be broken, this will be announced in the changelog and a DeprecationWarning will be triggered for one year, if possible, before compatibility is finally broken.
Warning
There is one exception:
APIs may be labelled as provisional. They are not guaranteed to be stable, and they may change or be removed without notice.
If you believe you have found a vulnerability, please use GitHub’s security advisory form or email Veit Schiele at veit@cusy.io.
