Compiz and Beryl are now merging their code. Many of the Beryl plugins have now been ported to Compiz.
Beryl and Compiz-Extra have merged to become Composite Community (a temporary name). Compiz-Core will be called Compiz.
After several weeks of discussion the leaders of Compiz and Beryl have agreed that the two communities shall reunite. This decision is supported by both David and Quinn and represents the majority decision of the administrators and developers in each community.
