 --------------------------------------------------
 
 Here are the topics that have been cooking.  Commits prefixed with
 '-' are only in 'pu' (proposed updates) while commits prefixed with
 '+' are in 'next'.
 
-Many fixes on the 'master' has been merged down to 'maint' and the
-tip of the latter is at v2.1.2 now.  Among the topics that have been
-cooking in 'next', easier ones have all graduated to 'master'.
-
-During the remainder of this cycle, I would like to see these topics
-to be in 'master' by the end of the 8th week in late October:
-
- - ref transaction updates by Ronnie and Jonathan
- - lockfile updates by Michael
- - replacement for contrib/workdir by Duy
-
-All of them are of rather nontrivial size, and would need to be in
-'next' for at least a few weeks, which would mean they must be in a
-good enough shape to go incremental by mid October.  I suspect that
-we might be cutting it a bit too close for some of them but we'll
-see.
-
-    Side note: I am not saying that I will ignore other topics; I am
-    just saying that I care about these three topics because their
-    changes have large impact on the current codebase, and they have
-    big positive impact on the future when done right.  We want to
-    see atomic updates to multiple refs.  We want to see our locks
-    behave sensibly.  We want to see safer way to work with multiple
-    working trees checked out of a single repository.
-
-    Other topics in flight are of smaller impact that I would not
-    worry too much about and tend to require less brainpower to
-    judge if the design is good, and I'd be happy to see them go
-    through the usual 'pu' to 'next' to 'master' with their own
-    pace, either by the end of this cycle, extending into the next
-    cycle---in that sense I do not care too much about them to
-    single any out.
