If you've been following the Joomla! project for a while, you know that the releases have been sporadic and non-predictable. Especially the releases for Joomla! 1.6 (alpha / beta) have been far apart. Until now, that is.
At J! and Beyond in Wiesbaden, Chris Davenport of the Joomla! Development team told the crowd that future Joomla! releases will be date-based. This means at first that new beta versions of Joomla! 1.6 will be released every 14 days. Beta 3 is scheduled for June 14th 2010. The result being that the version will be released with the bug fixes added up until that point. This will continue until we have a release candidate and then a stable version of Joomla! 1.6.
After the release of 1.6, the plan is a release of a new major version of Joomla! every 6 months. Which means a release of 1.7 six months after 1.6 is launched etc.
