Dear PETSc 'maint' branch users, In anticipation of the next 3.7 release of petsc - I've updated 'maint' branch in petsc git repository to 3.7 pre-release changes. If you 'git pull' on maint branch - you would get these 3.7 pre-release changes. To stay on 3.6 - you can switch to 'maint-3.6' branch. git fetch git checkout maint-3.6 I apologize for any inconvenience this has caused. Satish
