Hi guys,
here we are with UDOObuntu 2, the official version. No more RC versions to come. Of course this doesn’t mean that we are gonna stop working on UDOObuntu 2! On the contrary! It just means that we have reached a stable version.
Basically what’s changed is that now the Board Manager is supported. This means you won’t have to type
sudo apt-get update
sudo apt-get upgrade

to get the latest version of the Arduino Board Manager.
The other changes are contained in the changelog.
To get it just go on the Downloads section.
Enjoy!
