Randy Heit has updated the ZDoom News page with information on an upcoming beta of ZDoom v1.23, which should be out by the end of the week, which would bring the beta release up to number 28. This new beta will resolve the mouse issues people have been experiencing with b25 and other bugs, provide full support for missiles leaving decals on walls, and support the announcer voice from Blood (I have no idea what that means). Once this beta is out the door, Randy plans to release a non-beta 1.23, which will enable TeamTNT to release the Daedalus project.
In addition, someone has created a Russian translation support file for ZDoom. For more information, you can visit that site here.
