Checking on the status of opensource audio apps and plugins (previously known to me) is quite the sad sight, quite a lot of them have been abandoned 😔
I am thinking of tagging anything that:
1. has no stable release in 10 years
AND
2. has no single dev commit/change in 5 years
as "abandoned".
Alternatively if the project owner publicly states it is no longer maintained.
The amount of projects that fit into this criteria is not small. And I feel 10 & 5 year thing is quite generous..
