The Camel PMC decided to discontinue support for the camel 1.x line, currently at version 1.6.3 at the end of this year. We plan on having one last release (1.6.4) at the end of Q4 2010 to include all fixes on that branch until that time. There will be no more development, fixes or releases on the 1.x branch after that.
We are now focusing our efforts towards releasing Camel 3.0 early in Q1 2011 (see roadmap). The camel 2.x line will continue to be supported.
Many thanks to our community for the continued support.
