+ * When given an abbreviated object name that is not (or more
+ realistically, "no longer") unique, we gave a fatal error
+ "ambiguous argument". This error is now accompanied by hints that
+ lists the objects that begins with the given prefix. During the
+ course of development of this new feature, numerous minor bugs were
+ uncovered and corrected, the most notable one of which is that we
+ gave "short SHA1 xxxx is ambiguous." twice without good reason.
+
+ * "git log rev^..rev" is an often-used revision range specification
+ to show what was done on a side branch merged at rev. This has
+ gained a short-hand "rev^-1". In general "rev^-$n" is the same as
+ "^rev^$n rev", i.e. what has happened on other branches while the
+ history leading to nth parent was looking the other way.
+
+ * In recent versions of cURL, GSSAPI credential delegation is
+ disabled by default due to CVE-2011-2192; introduce a configuration
+ to selectively allow enabling this.
