I just noticed a message on the dev mailinglist:
> We've branched master for release-3.8 and created a v3.9.0-alpha.0 tag.
> This is because 3.8 is a "skip" release where we'll only do an internal
> data upgrade and then go from 3.7 to 3.9 directly.
Does that mean there will never be a (public) 3.8 release?
In a recent (November 2017) roadmap for the enterprise version, both 3.8 and 3.9 are mentioned.
