Testing and release planning

Main testing charter Also to check: everything reported between Oct 4, 2011 (deploy day for 1.17) and Oct 15, that we fixed before Oct 31

Other TODOs:

• Prepare for 1.19 beta testing by compiling a list of people who reported problems in 1.17.0, 1.17.1 & 1.18.0. Ask them to be on-call to test.
  • Mark and Chris to compile the list -- Amgine, et al.
  • Chris to possibly ask them to test trunk versions, definitely ask them to test the 1.19 branch.
  • Discuss testing community communication with Mark & Ashar (testing mailing list? meetings?)

Documents
