Version history

We follow Semantic Versions since the 0.1.0 release. We used to have incremental versioning before 0.1.0.

Semantic versioning in our case means:

  • Bugfixes do not bring new features, code that passes on x.y.0 should pass on x.y.1. With the only exception that bugfix can raise old violations in new places, if they were hidden by a buggy behaviour. But we do not add new checks.
  • Minor releases do bring new features and configuration options. New violations can be added. Code that passes on x.0.y might not pass on x.1.y release because of the new checks.
  • Major releases inidicate significant milestones or serious breaking changes. There are no major releases right now: we are still at 0.x.y version. But, in the future we might change the configuration names/logic, change the client facing API, change code conventions significantly, etc.
