Seeing unfortunately anybody else taking the lead, I'll likely issue a 4.4.0 release some time next week (I guess this is the appropriate version number given there are a few symbol additions)
If there are things that should critically go to the release, it is high time to submit merge requests. Said otherwise: try master to check if things are OK
My software is free, but my time generally not.
