Release Notes

Externals version: <a href="http://lcginfo.cern.ch/release/62a/>LCGCMT_62a</a>

General Changes

This is a major release of Gaudi. The main changes are:

• Repackaging of GaudiSvc mainly to reduce the size of the libraries that users may need to override (task #23931, patch #1816).
  (Marco Clemencic)
• Removed GaudiPoolDb and introduced RootCnv.
  The Application Area project POOL is not used anymore, but an alternative based on ROOT (can read POOL files) has been copied from LHCb. The new conversion service is still developed in LHCb and comments/bug reports have to be directed to Markus Frank.
  (Marco Clemencic, Markus Frank)
• Fixed bug #85377: GaudiTuple tuple does not understand ulonglong
  (Chris Jones)
• Modified ApplicationMgr to return non-zero in case of failure during finalization and to print different messages in finalization and termination in case of errors.
  (Marco Clemencic)
