+ * "git interpret-trailers" learned to properly handle the

+
+ * "git am" learned "--message-id" option to copy the message ID of
+   the incoming e-mail to the log message of resulting commit.
+
+ * "git send-email" learned "--transfer-encoding" option to force a
+   non-fault Content-Transfer-Encoding header (e.g. base64).
+
+ * "git push" into a repository with a working tree normally refuses
+   to modify the branch that is checked out.  The command learned to
+   optionally do an equivalent of "git reset --hard" only when there
+   is no change to the working tree and the index instead, which would
+   be useful to "deploy" by pushing into a repository.
+
+ * "git new-workdir" (in contrib/) can be used to populate an empty
+   and existing directory now.
+
+ * Credential helpers are asked in turn until one of them give
+   positive response, which is cumbersome to turn off when you need to
+   run Git in an automated setting.  The credential helper interface
+   learned to allow a helper to say "stop, don't ask other helpers."
+   Also GIT_TERMINAL_PROMPT environment can be set to false to disable
+   our built-in prompt mechanism for passwords.
+
+ * "git branch -d" (delete) and "git branch -m" (move) learned to
+   honor "-f" (force) flag; unlike many other subcommands, the way to
+   force these have been with separate "-D/-M" options, which was
+   inconsistent.
+
+ * "diff-highlight" filter (in contrib/) allows its color output to be
+   customized via configuration variables.

+ * Some filesystems assign filemodes in a strange way, fooling then
+   automatic "filemode trustability" check done during a new
+   repository creation.  The initialization codepath has been hardened
+   against this issue.
+
+ * The codepath in "git remote update --prune" to drop many refs has
+   been optimized.
+
+ * Long overdue departure from the assumption that S_IFMT is shared by
+   everybody made in 2005, which was necessary to port to z/OS.
+
+ * "git push" and "git fetch" did not communicate an overlong refname
+   correctly.  Now it uses 64kB sideband to accommodate longer ones.
+
+ * Recent GPG changes the keyring format and drops support for RFC1991
+   formatted signatures, breaking our existing tests.
+
+ * "git-prompt" (in contrib/) used a variable from the global scope,
+   possibly contaminating end-user's namespace.

  * "git checkout $treeish $path", when $path in the index and the
