My eternally in-progress game has a new hybrid dungeon generator now. It supports a variety of dungeon generation algorithms (so I can satisfy my never-ending desired to keep creating them) and will even mix them together in a single dungeon.
The latter is something I've wanted to do for ages but only very recently figured out how (thanks to an offhand comment from Brogue's Brian Walker at last year's Roguelike Celebration). The tricky part is ensuring you still end up with a fully connected dungeon.
If you want to see the current state, you can play with the generator here:

At shallow depths, it tends to use a single rooms-and-passages generator. But if you pick a lower depth and click a few times to roll new dungeons, you'll start to see hybrids that mix a few different algorithms together. It still needs a lot of work, but I'm really proud of it.
