* "git rebase" learns "--trailer" command to drive the
interpret-trailers machinery.
+ * "git fast-import" learned to optionally replace signature on
+ commits whose signatures get invalidated due to replaying by
+ signing afresh.
+
+ * "git history" learned the "split" subcommand.
+
Performance, Internal Implementation, Development Support etc.
--------------------------------------------------------------
* Adjust test-lint to allow "sed -E" to use ERE in the patterns.
+ * Clar (unit testing framework) update from the upstream.
+
+ * Reduce system overhead "git upload-pack" spends on relaying "git
+ pack-objects" output to the "git fetch" running on the other end of
+ the connection.
+
+ * Add a coccinelle rule to break the build when "struct strbuf" gets
+ passed by value.
