- Copy Input To dialog allows input to one session to be copied to all or a subset of other sessions. (Like 'Send Input to All' in KDE 3 but more flexible)
- Drag and drop re-arrangement of tabs and movement of tabs between windows.
- Better warnings and fallbacks if starting the shell fails (due to missing binary or crash).
- Transparency is available by default (with an option to forcibly disable it)
- Support for bi-directional text rendering. (Diego Iastrubni)
- New 'Dark Pastels' colour scheme (adapted from one by Christoffer Sawicki)
- Mouse-wheel scrolling in less and other non-mouse enabled terminal applications
In other news, like several other KDE developers I have started using git and git-svn locally. It is a huge improvement over SVN, especially when developing experimental features that touch many parts of the code alongside bug fixes to the current trunk. It does make you wonder how you ever managed before. A quick "git branch" on my current local checkout shows 10 branches for various little features in progress, for example:
Interestingly though and perhaps paradoxically given the open nature of the project, one of the most useful benefits is the ability to create branches to work on features without telling the whole world. There is much emphasis on the benefits of incremental development but at the same time I think it is important to be able to do some things in private so that they can arrive on the scene with a bang that gets attention. Compiz or git being good examples.
