Almost all oft their breaking changes over the last few months were about their docker-compose setup and the simplification of the same. They've startend out with multiple purpose-specific (micro) containers, which turned out as a Bad design decision. These changes require manual intervention but seem to be mostly finished, so I don't expect these to be many breaking changes in the forsseeable future.

The better you plan ahead, the fewer breaking changes you have to impose on your users.

I agree. From what I've read, they now have (published) plans for what's ahead.
