They did some neat game mechanic tweaks, especially of the previously useless units: mechanics and thieves being able to revive and capture vehicles. Keeps the spirit of the old game but makes it more fun.
For me, Shotcut, Openshot, Flowblade, Olive and Pitivi have been crashing to often to be worth using. Openshot used to be less flaky when I used it a few years ago when it was in GTK but the Qt version has not been stable to me.
Kdenlive is amazing though, especially the timegraphs for applying effects, and the clip proxying which makes it amazingly smooth for large projects on old laptops. I don't think any of the other free video editors come anywhere close.
