v4.0.0 release

[Leif Hedstrom <zw...@apache.org>]

Hi all,

part of the new release process, I've cleaned up all Jira and branches to reflect the new semver versioning. As such, the next stable release will be v4.0.0, and it's currently tracked in the 4.0.x branch on GIT.

I'd like to cut the v4.0.0 release candidate this Friday (8/23), with a release date of 8/30. Below is a list of all the bugs from v3.3.5 that got into v4.0.x, please review and test this now and after the release candidate is cut.

Cheers,

-- Leif
