From DotProjectWiki

The dotProject Code Repository is broken into two main branches:

stable_2 is the current bug fix release - based on the last stable release (2.1.1).

• The stable_2 access string is:
  • svn co https://dotproject.svn.sourceforge.net/svnroot/dotproject/branches/stable_2/dotproject

If you wish to do an update on your own site then you should use stable_2

trunk is the current development release - it is the branch in which new features are incorporated and will be used as the basis for the next release.

• The trunk access string is:
  • svn co https://dotproject.svn.sourceforge.net:/svnroot/dotproject/trunk/dotproject

The Trunk Branch should not be used on any production system as there is no guarantee that the code is stable, tested, or even functional at any given point in time. If you wish to review the Trunk Branch to see the status of development, please feel free. Regardless, please understand that support requests on trunk may be ignored due to the constantly changing nature of this code.
