About a week ago I updated the KDE 4.1 backports for Lenny with the fourth and last revision of KDE 4.1.
As previously announced, this will be the last update available at http://kde4.debian.net
What is next?
The repository will continue there, so Lenny users can choose between KDE 3.5.9+ and KDE 4.1.4. But since 4.1.4 packages are not official, they do not have support: no bugs in the BTS or security updates.
If you are using Debian Lenny for stability and security purposes, you should use KDE 3.5.
Testing users (future squeeze, current Lenny) can continue using them until KDE 4.2 reaches testing. Again, remember, no bugs in the BTS or security updates, but they will get a clean upgrade to KDE 4.2 in the near future.
Unstable users. I have found that there are people using unstable with the backports, when they should be using experimental KDE 4.1. If this is your case, you can stick with 4.1.4 until KDE 4.2 reaches unstable or switch to experimental in a few days and get KDE 4.2 (no yet! it needs to be released first :) ).
Last, but not less important, thanks to all the people helping with the backports: MoDaX for helping as backup and the rest of the Qt/KDE team who worked in the experimental packages. HE, zobel and aba for his sysadmin tasks. apol for allowing me torture his PowerPC machine. All those who translated the instructions into their languages and
helped to others users in mailing lists and forums.
A quick note about KDE 3.5 to be released in Lenny
As most of you have realized, the packages of KDE 3.5 in Lenny and unstable are a mixture of KDE 3.5.9 and 3.5.10. Given that KDE 3.5.10 was released after Lenny was frozen, we could not push this new version into Lenny, however the KDE 3.5 packages were patched about June last year with the latest changes in KDE 3.5 from the KDE subversion. This means some of the modules with the version 3.5.9 are exactly the same that is shipped as 3.5.10.
The only “big” stuff missing are the kicker improvements shipped in kdebase and some bug fixes in kdepim. But in global, it is closer to KDE 3.5.10 that to KDE 3.5.9. If you want to see what changes are you missing, check the KDE 3.5.10 changelog.
