On March 10, 2005, the Mozilla Foundation announced that they would not release any further official versions of the suite beyond 1.7.x. However, the Mozilla Foundation emphasized that they would provide infrastructure for community members who wished to continue development. In effect, this means that the suite will still continue to be developed, but not by the Mozilla Foundation itself. To avoid confusing organizations that still want to use the Mozilla Suite, it was announced that the new, community-developed product will be named "SeaMonkey", with version numbers that start at "1.0".
So, the organisation has sort of "branched" with the mainstream concentrating on the development of the standalone Firefox and Thunderbird.
