+We are almost done with this cycle.  As we found out a ntohll
+regression that broke big endian boxes with builtin_bswap32/64
+supplied by their compilers way too late in the cycle, I'm planning
+to queue a revert for a single patch, which may or may not break
+Windows ARM64 support that was newly added during this cycle.
+Hopefully it is a better tradeoff for the entire Git community to
+drop support added by an unreleased product than to break a platform
+that has been working OK.

 Copies of the source code to Git live in many repositories, and the
 following is a list of the ones I push into or their mirrors.  Some
 repositories have only a subset of branches.
