[DEV] Shattered levelgen changes and beta soon!

Hey folks, the beta for Shattered Pixel Dungeon v2.4.0 should be ready to start this coming week!

The beta will have everything I've shown off so far, including a new item category, changes to alchemy, and changes to the Duelist. There are also some levelgen additions! Entrance and exit rooms in particular are going to become more visually varied.
