Clementine the music player is my go-to example of this phenomenon. Its got 750 commits in since its last release in 2016, there is regular merging, but the project management is in a place where trying to deploy builds to every platform is acting as a barrier to any new releases. It recently finally merged its Qt5 support into master (which was in a working state since 2014) about two months ago. That might help the release process. What doesn't help is that a consumer facing product of that scale is a nightmare to manage - it has over 2k open issues on Github but probably 95% of them are "I don't know how to do X" tech support kinds of things.
