Update: Caffeine 1.0 has been released. Read more about it here.
The pace of development has been frantic since the first release of Caffeine last month. Caffeine is an application that allows you to quickly and easily disable the screensaver and powersaving features of your computer, so that you can watch a long flash video or give a presentation without your display switching off. I feel some temptation to hold back the next release of Caffeine until the program is perfect, but that way madness lies. And so, with that in mind, I am pleased to announce the release of the 0.2 version of Caffeine for Linux!
This new version is a massive step forward, with loads of new features and improvements. In fact, so much has changed, it’s practically a new program. Specifically:
- Incredible new icons (my own amateurish attempts have been thankfully retired)
- Ability to select from a list of time intervals, and have Caffeine prevent powersaving for that amount of time
- Ability to specify a custom time interval, and have Caffeine activate for that period
- Official support for Kubuntu 9.04 and Xubuntu 9.04 (the previous release supported Ubuntu 9.04 only)
- A new Launchpad project page
- Fixed the bug that would cause Caffeine to quit if activated immediately after login
I’d like to thank all of the people who helped with developing or testing Caffeine. I’d also like to give a special “thank-you” to Tommy, who provided Caffeine with the new artwork, the new timed activation features and many other improvements too numerous to list here.
Caffeine is now available through a Personal Package Archive (PPA) provided by Launchpad. This means that once you install it, any subsequent updates will show up in your regular “Update Manager ” window.
