  * "interpret-trailers" has been taught to optionally update a file in
    place, instead of always writing the result to the standard output.
 
+ * Many commands that read files that are expected to contain text
+   that is generated (or can be edited) by the end user to control
+   their behaviour (e.g. "git grep -f <filename>") have been updated
+   to be more tolerant to lines that are terminated with CRLF (they
+   used to treat such a line to contain payload that ends with CR,
+   which is usually not what the users expect).
+
+ * "git notes merge" used to limit the source of the merged notes tree
+   to somewhere under refs/notes/ hierarchy, which was too limiting
+   when inventing a workflow to exchange notes with remote
+   repositories using remote-tracking notes trees (located in e.g.
+   refs/remote-notes/ or somesuch).
+
+ * "git ls-files" learned a new "--eol" option to help diagnose
+   end-of-line problems.
+
+ * "ls-remote" learned an option to show which branch the remote
+   repository advertises as its primary by pointing its HEAD at.
+
+ * New http.proxyAuthMethod configuration variable can be used to
+   specify what authentication method to use, as a way to work around
+   proxies that do not give error response expected by libcurl when
+   CURLAUTH_ANY is used.  Also, the codepath for proxy authentication
+   has been taught to use credential API to store the authentication
+   material in user's keyrings.
