"After discussing the amount of changes that have gone into the 4.5 branch post-RC3, the release team has decided to wait another couple of days for things to settle down and to re-tag the 4.5.0 release from branch in a bit more than an hour, at 1600 UTC. We'll push the further schedule for the 4.5 series for 1 week as well. The current plan for 4.6.x is not affected.
There was a number of last-minute changes introduced we didn't feel completely comfortable shipping. Also, delaying the release a bit gives us the chance to have zero-day packages available for more OSen than we'd have with only about 24h head-time for packagers, and will likely lead to better and more complete material for the press to be available and seeded early."
So we're delayed by a week, but the result will be a better 4.5.0 release for everyone. This means that important fixes for issues with Dolphin, Nepomuk and Plasma Desktop that did not make the original deadline will now be a part of 4.5.0. Some of these fix crashes, such as a problem in Dolphin with showing metadata, and some are more technical packaging issues such as a library from kdebase/apps/ whose .so version wasn't bumped up even though it broke binary compatibility.
As noted in the email, the 4.6 release schedule is not affected by this as we already branched off for 4.6 development a few weeks ago and those efforts have already been moving forward at a good pace.
Kudos to those who worked on the last-minute fixes, as it shows commitment to quality, and to the release team for being able to make tough decisions in a responsible manner and communicate them clearly.
Here's looking to a great 4.5.0!
