Established based on what conventions? I'm going based on the semantic versioning guidelines here:
http://semver.org/ Basically what I'd like to understand is whether Google cares about this or not, because changing public API's is a big problem for downstream projects. It means that if you want to write a library that uses proto-bufs you can't inter-operate with other libraries that also use protobufs. - Patrick On Wed, Apr 16, 2014 at 3:24 PM, Ilia Mirkin <imir...@alum.mit.edu> wrote: > While I don't speak for Google, I believe it's fairly well-established > that 2.4 and 2.5 are considered to be "major" releases.
