 Here are the topics that have been cooking.  Commits prefixed with
 '-' are only in 'pu' (proposed updates) while commits prefixed with
 '+' are in 'next'.
 
-There are a few more topics in flight that look sane and trivially
-correct that I would feel safe to merge down to 'master', but what
-we have in 'master' should be a pretty similar to the final, from
-the point of view of features and new fixes.  I'd like to see people
-focus on catching and fixing last minute regressions and
-incompleteness in the topics that have already in 'master' for the
-upcoming release.
-
-New topics that are not relevant for the goal to release a complete
-and regression-free 1.8.3 may not be queued even on 'pu' until final
-to reduce hassles on integration testing (I do not mean that it is
-forbidden to work on and discussing new topics on the list. It is
-just the patches won't be considered as formal submission and they
-won't hit 'pu').
+The tip of the 'master' branch is tagged as v1.8.3-rc1.  We seem to
+have a few interesting topics that are being discussed but it is
+unlikely I'll be picking them up in 'pu'.  As we already have merged
+enough changes to 'master' during this cycle that can potentially
+cause unforseen regressions, let's not merge topics that are not
+regression fixes from 'next' to 'master', either, until the final
+release.
