Please add a note and link from https://www.abisource.com/developers/ to GNOME gitlab AbiWord page.
https://www.abisource.com/developers/ still points to viewvc only. A note that viewvc is an archive and that the new location for development is on https://gitlab.gnome.org/World/AbiWordwould help since Distributions points AbiWord upstream to https://www.abisource.com/ (for one https://tracker.debian.org/abiword) or even abiword.appdata.xml in this repository.
