We have been continuing to port existing drivers to the new code-generation framework. Also have we been implementing new protocols (Mostly based on paid gigs from the industry). A lot of bug-fixing has been done and we're looking forward to a big refactoring and brainstorming Hackathon form 2019-12-17 - 2019-12-19 in Weinheim, where we are going to work on a proposal for the version 1.0.0 API.

Community Health:

This quarter for most of the time activity on the mailing-list and in the commits had dropped to worrying levels. This was mainly related to high workload on the day-jobs of the community members. However in the past 2-3 weeks a lot of new people have joined discussions and submitted PRs and the existing comitter- and PMC activity has picked up again.
