 Here are the topics that have been cooking.  Commits prefixed with
 '-' are only in 'pu' (proposed updates) while commits prefixed with
 '+' are in 'next'.
 
-We would need to start slowing down to prepare for -rc0 preview at
-the end of this week and then feature freeze.  Some topics that
-joined 'next' late may want to stay there for the remainder of this
-cycle.  Many of the accumulated fixes have been flushed to 'maint'
-and Git 2.0.3 has been tagged.
