I'm so behind on all fronts, including PBE Games news. I haven't published much since the last update, 
The Sand Coast, but I have put out a couple new products since then. Here's a quick rundown on the latest 
Dungeons in Blue releases:
All the geomorphs in these sets contain a mix of corridor styles and sizes, and several have cross tile features such as water, sewers and lava. I also tried to include a number of edge geomorphs in each of these sets, since even the best dungeon must end, eventually. Here are previews of each of these sets (one-third scale):
|  | 
| Set J | 
|  | 
| Set K |

| Set L | 
See what I mean about quick?
