Is this project actively supported OR up to date with latest DASH revisions

Thanks for all the hard work.
The last closed issue is from 2018.
One of the unanswered issues asks if the project supports DASH second edition.
Mailing list link is broken. http://vicky.bitmovin.net/mailman/listinfo/libdash-dev
Does this reference code still pass all (most?) of the test vectors?
