Quoting the official announcement
The time has come to delurk again, and present the world with another release of DoomRL! This is a intermediate release on the long and winding road towards DoomRL 0.9.9. Some of the features that I wanted to push intothis release have beed delayed, but fear not, theres still a couple of things to try out!
The most important part are interface changes, including (but not limited to) message coloring, past message viewer, archivising of mortems in a separate folder, screenshots in plaintext at BBCode format.
Gameplay changes include adding weapon modifications, Mancubi, new level types and new traits. Finally there’s the backpack ;). A lot of changes also happened in the old traits, including a lot balance work. Balance work has been done on other aspects of the game also.
