As I mentioned in the footer of the post on the Hudson 1.344 release, there were a couple big regressions in the 1.344 release that were causing a number of users issues (such as issue 5536 and issue 5546).
As a result, Kohsuke and the team have quickly pushed out a hot-fix release: 1.345. Here's the break down:
Bugs fixed:
- Update center retrieval, "build now" link, and real-time console update was broken in 1.344 (issue 5536)
- Fixed the backward incompatibility introduced in HUDSON-5391 fix in 1.344. (issue 5391)
If you have already updated to 1.344, your "Update Center" is most likely busted and you'll need to download the hudson.war
file manually.
You can go grab the latest .war file straight from hudson-ci.org
or if you're using a native package, use your package manager to upgrade.
