### Development Series

This is work in progress, so some pieces may be broken and the documentation out of sync. But it is a good place to look for what is going on.

- v2_3_2, released on April 06, 2010 (Manual,Installation instructions,Tarball)
  - Fixed a security bug in the way certificate/proxy DN(s) are handled. If you are upgrading the installation rather than full install, you should patch the condor_mapfile used by Condor daemons in your installation using the convert_condormap tool available from the glideinWMS download page. For additional security, users should add new DN to the condor_mapfile only by using the glidecondor_addDN tool available in the glideinWMS/install directory.
- v2_3_1, released on March 11, 2010 (Manual,Installation instructions,Tarball)
  - Documentation Changes. There are no code changes since v2_3
- v2_3, released on February 02, 2010 (Manual,Installation instructions,Tarball)
