Things have sped up a lot in the Godot development team since the beginning of 2018, to be able to finalize 3.0 and release it in January. The release freeze has been announced, meaning that enhancements and non-critical bug fixes are no longer being merged, to ensure that the master branch can stabilize and eventually be ready for the final release. This means of course that many known issues won't be fixed for 3.0, but will have to wait for 3.1 or for the maintenance 3.0.x releases which should start arriving in February.
