This seems to be one of the main differences between the two projects, the Release Cycle. While Hudson is right now at 1.396 Jenkins is already at 1.400. I wander if the bugfixes in Jenkins are all merged back into Hudson, since there are quite some „nice“ fixes in there, especially some for Maven projects (see the Jenkins Changelog). Both projects have still not fixed my personal highlight bug (Error Generating Documentation). Hope that one of those will fix it soon. I promise that I will use the corresponding fork and will not look back 😉
Lets see, which fork is going to win this race.
