3.13.0 contained a bug in the Linux implementation of HID - 3.13.1 fixes this, but as it only concerns Linux we decided to leave the other platforms on 3.13.0.
3.13.1 therefore contains no other changes except for this bugfix for linux.
We are working on 3.14.0 though, yet no ETA on this. The last time I asked if the community would be interested in a 3.14 release there wasn’t much feedback, otherwise I would have pushed a 3.14 release for the symposium. But such a release can’t be a 2/3 person show.
Stay tuned for future dev meetings where this will be discussed for sure!
