After finally getting themes support about 2 weeks ago, another Kupfer version (v206) was released today bringing a huge list of bug fixes and more importantly, reduced memory usage. The changelog says the Kupfer runtime memory should be reduced by 10-30% thanks to the reimplementation of icon cache.
You can check out all the bugs fixed in the latest Kupfer v206 @ kaizer.se.
With this release, there's also good news for Ubuntu 10.04 users: the latest Kupfer has finally been packaged for Ubuntu Lucid Lynx too so you can finally install it from the PPA (until today the PPA provided a very old Kupfer version for Lucid).
Add the Kupfer PPA and install the latest v206 in Ubuntu 10.04, 10.10 and 11.04 using the commands below:
sudo add-apt-repository ppa:kupfer-team/ppa sudo apt-get update sudo apt-get install kupfer
Tip: Kupfer comes with 2 extra themes - to change the theme, go to the Kupfer Preferences and on the Plugins tab enable the "Custom Theme" plugin, then select among the other 2 themes: dark or square. If you want to create your own theme, see HERE.
