We are just a few days into 2010, but the standard (basic) window manager for X.Org, TWM, has finally received some updates. TWM has been around for 13 years and under the hands of many developers, but is now receiving some new development love from Eeri Kask. Eeri has been hacking away at TWM for a few years now and has made many improvements already, but this is the first time since September of 2008 that he is announcing some of his new work.
Eeri's latest TWM work includes making support for new options configurable through the autoconf build script (for those that prefer a traditional TWM), a number of new/updated keywords, X Render support has been added (including transparency support). new arguments added as a prerequisite to xcompmgr based composited transparency, and improvements to frame geometry / focus management.
More information on these new TWM window manager improvements can be found on the X.Org mailing list
