I would be interested in that too, I was very involved back then, designed the first Roperace levels, a fort, etc.

Admittedly, development overall has slowed down in the last years but there were still occassional changes.

Right now, we're stting on a pretty large number of commits after version 1.0.0, so I think a new release is long overdue. So there was work behind the scenes, it just wasn’t released yet.

But even if we make a release now, don't expect huge changes on the player side. Most of the commits are maintenance-/bugfix-related (which is still important ofc).

As for me, I haven't been working on Hedgewars for a long time. Basically, I consider this game to be more or less "technically complete" anyway. My main work on Hedgewars in the past was the push for version 1.0.0 (which was still a LOT of work).

For post-1.0.0 releases, I originally planned to extend the singleplayer mode by a lot (more campaigns and missions, basically). I think the game would feel "truly complete" with a better and more content-rich singleplayer mode. I think a better singleplayer mode will be very beneficial because we only have a small multiplayer community.
It sounds simple but thinking of new missions is harder than it sounds.

But my interest currently has shifted to my personal game projects (mostly in the Luanti community, where I’ve been almost hyperactive). My interest works in mysterious ways, I keep jumping from project to project. But I haven't forgotten entirely about Hedgewars.

That was just about me, of course. As for the other devs, you have to wait for their replies, obviously (I can't speak for the whole team).

Though last commit is 4 weeks old and they are sparse in general.
