- Adding new restart icons, work in progress
- Adding new broadcast icon (microblogging)
- Adding new user status icons based on simple icons from new visual identity
- Adding more weather icons and reworked microblogging
- Starting to add weather icons, work in progress
- Adding MessagingMenu Chat and Email icons
- Adding Tomboy, Session Menu and -dark nm-applet wifi icons
- Adding microblogging icon for messagemenu
If you're using Ubuntu Lucid 10.04, all you have to do is "sudo apt-get update && sudo apt-get upgrade" to use these updated packages.
For Ubuntu Karmic and Jaunty, the packages are already available in the WebUpd8 PPA so take a look at the instructions in this post to see how to install ubuntu-mono (icons) as well as the new Ambiance and Radiance themes in Ubuntu Karmic and Jaunty.
