Miro 3.5 has been released.
The major improvement, in my personal point of view, is the possibility to convert video and audio files for other devices/OS' (Android OS for example).
Ubuntu 10.04 is bundled with Miro 3.0 though. To upgrade it, a new repository needs to be added. We add it with:
sudo add-apt-repository ppa:pcf/miro-releases
then we update the source list:
sudo apt-get update
and install/upgrade Miro to the latest version:
sudo apt-get install miro
Enjoy the file conversion...
