Breaking Changes

edit

As a general rule, we strive to keep backwards compatibility between minor versions (e.g. 5.x to 5.y) so you can upgrade without any configuration file changes, but there are breaking changes between major versions (e.g. 5.x to 6.y).

We also list the breaking changes at the top of the release notes for each version.
