The resolved issues were reviewed.

The art state machine was modified to re-enable the random access feature support for event displays.  It was asked if it is urgent to release this quickly or can it wait to the next scheduled release of art.

Marc Paterno presented several slides with detailed information.  You may obtain the slides at: art news. The following is a summary of the intormation presented on the slides:

ROOT 6 news was announced.

GDML formula parsing has been re-added.

Blockers for getting an art suite build using ROOT 6.08:

  • LLVM/clang name mangling bug,
  • PyROOT failure,
  • Exception catching in ROOT macros,
  • gcc is not supported for building ROOT on macOS do to problems with LLVM/clang support,
  • XCode versions depend on macOS version

Question for experiments is should we switch to clang on macOS for the art suite?

Docker support for the scisoft bundles was proposed.

Mu2e has succeeded with an upgrade to art v2 and ROOT 6.
