The latest version of Firebird, a relational database offering many ANSI SQL standard features that runs on Linux, Windows, and a variety of Unix platforms, is now available for all Ubuntu supported releases.
The first update for Firebird 2.5.2 has been uploaded to the official PPA and now it provides support for all the Linux distributions still maintained by Canonical.
According to the developer, a lot of security fixes have been added from the Debian unstable repository, and the support for Ubuntu 8.04 (Hardy Heron) and Ubuntu 11.10 (Oneiric Ocelot) has been dropped.
The PPA installation is done very easily and users only have to enter a few commands in the terminal:
sudo add-apt-repository ppa:mapopa/ppa
sudo apt-get update
sudo apt-get install firebird2.5
