We're extremely excited to announce the availability of RT 4.2.0rc1 -- the first release candidate for the next major version of RT.
We would be thrilled to hear your experiences installing or upgrading to this release; the more feedback we get, the sooner the official release of RT 4.2.0 can occur. Please be sure to review the upgrading documentation available in the distribution in docs/UPGRADING-4.2, as there are a number of backward-incompatible changes that come along with the new version number. Upgrading documentation is also available on the Best Practical website along with the rest of the RT 4.2 documentation.
A partial list of the new features in RT 4.2.0 was posted previously. In the coming weeks we'll continue with more posts to describe and demonstrate new features.
In anticipation of the final RT 4.2.0 release, we're also starting to schedule upgrades. If you have questions about upgrading or other aspects of RT 4.2.0 you can get in touch with us at firstname.lastname@example.org.
