+Git 2.28 has been tagged.  We'll go slow for a few days to gauge the
+initial reaction to it and see if there is no major brown-paper-bag
+issues discovered.  Following that, majority of topics that have
+been cooking in 'next' will be merged to 'master', the tip of 'next'
+will be rewound and rebuilt on top of the updated 'master', near the
+end of this week.  The 'next' branch then will start taking new
+topics after that.
+
+During the next cycle for 2.29, we will decide the direction of
+follow-up work, if any is needed, for the init.defaultBranch topic
+we did the last cycle.
