Hi all, The build in branch-3 is not yet green; there are ~25 test failures. It is a common practice that we shouldn't push changes on top of a broken build unless they are addressing test failures. Some people (mainly Aman Raj, Chris Nauroth, and Laszlo Bodor) are working hard to stabilize the b

Some people raised a valid point that branch-3 is a maintenance branch. If we really aim 3.2.0 to be a maintenance release then we should minimize breaking changes and prohibit new features. In this case Spark cannot go away and the only thing we can do is deprecate it. It also means that we should

Hi Kirti, Thanks for bringing up this topic. The master branch already has many new features; we don't need to wait for more to cut a GA. The main criterion for going GA is stability thus I would consider regressions as the only blockers for the release. If I recall well the only regressions di
