  * "git submodule" learns "set-branch" subcommand that allows the
    submodule.*.branch settings to be modified.
 
+ * "git merge-recursive" backend recently learned a new heuristics to
+   infer file movement based on how other files in the same directory
+   moved.  As this is inherently less robust heuristics than the one
+   based on the content similarity of the file itself (rather than
+   based on what its neighbours are doing), it sometimes gives an
+   outcome unexpected by the end users.  This has been toned down to
+   leave the renamed paths in higher/conflicted stages in the index so
+   that the user can examine and confirm the result.
+
+ * "git tag" learned to give an advice suggesting it might be a
+   mistake when creating an annotated or signed tag that points at
+   another tag.
+
+ * The "git pack-objects" command learned to report the number of
+   objects it packed via the trace2 mechanism.
+
+ * The list of conflicted paths shown in the editor while concluding a
+   conflicted merge was shown above the scissors line when the
+   clean-up mode is set to "scissors", even though it was commented
+   out just like the list of updated paths and other information to
+   help the user explain the merge better.
+
+ * The trace2 tracing facility learned to auto-generate a filename
+   when told to log to a directory.
+
+ * "git clone" learned a new --server-option option when talking over
+   the protocol version 2.

+   as a submodule, but when the HEAD of the inner repository is on an
+   unborn branch, it cannot be added as a submodule.  Worse, the files
