There was supposed to be an update to Sauerbraten "Cube 2" in November, but that didn't happen in November or December. Fortunately, the major update to this long-standing open-source first person shooter is still forthcoming.
In November was when I wrote about the 2012 Cube 2: Sauerbraten update being planned once all the maps were readied. The SVN development repository was quite active, but no release was made on time as planned. This was to be the first major update in two years while Sauerbraten originally began in 2004 as a re-design of the original Cube Engine.
December has come and gone and there was no Sauerbraten update that was cooked for a 2012 release. Fortunately, it's still coming and there's marked interest in the new release. The forum thread concerning the "November release plans" continues to be quite active.
On the development side, the SourceForge SVN repository for Sauerbraten is still very active. The most recent SVN commits are hours old. Most of the Sauerbraten development activity in recent days/weeks concern map updates, sound/asset improvements, and other minor work.
It's looking like we'll see the next Sauerbraten game update out in early 2013. For those not familiar with Sauerbraten, visit Sauerbraten.org. Embedded below is an older Sauerbraten game-play video.
Also still being actively developed is the Tesseract fork of Sauerbraten, which delivers vastly improved graphics and other engine-level improvements to the open-source code-base. The Tesseract Git repository is still seeing new commits with the most recent work being from yesterday.
