We recently decided not to have a spring 2018 schema change release. As usual, we still have some bits left over to finish up from the last spring schema change. More importantly, we’re making a concerted effort to improve the user experience (UX) of the MusicBrainz site — more on that in a blog post later.
We may decide to do an autumn 2018 schema change, but this depends on how well our UX efforts progress over the course of winter and spring.
