• Some performance improvements with communicating with the DIRAC server (reduced Dirac calls/reduced code fluff in Ganga)
• Some older configuration settings have been deprecated, some new configuration options have been added.
  Removed: DiracOutputDataSE, load_default_Dirac_backend, DiracDefaultSE
  Added: RequireDefaultSE, statusmapping (for devs), queueable_dirac_statuses (for devs), userVO
• Can now use the bashrc directly from dirac-ui and elsewhere so don't need a Ganga specific env conig file
• DIRAC 'Completed' jobs are now considered to be 'running' due to the transfer of output data
• Fixed bugs where files vanished during jobs completing and jobs reverting status within DIRAC fixed

---

ganga/python/GangaLHCb

• All new DIRAC settings have been made configurable within LHCb config
• LHCb config now managed LHCb specific settings (RequireDefaultSE, DiracCommandFiles, userVO, allDiracSE)

• Added initial support for LHCb specific integration tests

---

ganga/python/GangaAtlas

• Ignore comments in files input for --inPfnListFile
• Added the output_loc_to_input option to AthenaSplitterJob to map input files to output dirs

  direct the different outputs to appropriate dirs
• Patches from HammerCloud to set homepackage correctly and use AGIS JSON file for queue/DDM mapping
• Some Atlas code cleanup

---

ganga/python/GangaLSST
