I'm surprised they are still making breaking changes, and they plan to make more (they are already working on a 4.0).

I didn't see any breaking changes in the release notes but I may have missed them. Maybe they don't use SemVer?

Arrow uses SemVer, but the library and the data format are versioned separately: https://arrow.apache.org/docs/format/Versioning.html
