					      Beta releases
and Product Management
Gabriele Cosmo (CERN/IT-API)
• Addressing recommendation #4.2:
   “ We recommend the adoption of more frequent, though not necessarily fully
     tested, “beta” releases that address important blocking problems. They
     should be available to all users. These “beta” releases are in addition to
     having a stable and working version of the program at any time, with a
     documentation of all known bugs or deficiencies in that particular version ”
   and recommendation #4.3:
   “ We recommend defining and managing the complete product tree, including
     documentation as well as the code, as part of a release. If the documentation
     is not ready, the release cannot be deemed to be ready ”
