There are several versions currently maintained or developed :
- 5.3 (recommended)
- trunk (future version, only for developers).
If official packages are available for your distribution, we recommend to use them (i.e. using apt on Debian-like systems).
Debian and derivatives
.deb packages available for Debian and derivatives such as Ubuntu.
The official Debian repositories (status in the PTS ) contain packages of FusionForge 5.3.x, for Debian distributions unstable (sid) and testing (jessie) .
Note that Debian old-stable (squeeze) still has packages for FusionForge 5.0.x.
Some packages will still be named after gforge- prefix whereas some are named fusionforge-. See  for more details on these official packages.
See README.Debian files in /usr/share/doc/[fusionforge*|gforge*] dirs for details on installation instructions or configuration issues.
In addition to these official packages for stable fusionforge releases, the "experimental" Debian section may also contain snapshots of the state of the trunk during development and stabilisation periods.
Users of Ubuntu or other versions of Debian will find instructions on how to get the unofficial (Debian-wise) packages or packages for other versions of fusionforge (snapshots) in Installing/DebianCompatiblePackages or Installing/UbuntuRepositories.
Other (RPM based) distributions
.rpm packages are available for RedHat/CentOS 6, see RPM Installation for more.
Virtual Machine image for testing
An image for a Virtual machine development environment is made available for easy testing. Note that it's meant to be used for evaluation and for getting familiar with development, rather than for a production site.
