 Fixes since v1.6.6
 ------------------
 
+ * "git branch -a name" wasn't diagnosed as an error.
+
+ * "git fast-import" choked when fed a tag that do not point at a
+   commit.
+
+ * "git grep" finding from work tree files could have fed garbage to
+   the underlying regexec(3).
+
+ * "git grep -L" didn't show empty files (they should never match, and
+   they should always appear in -L output as unmatching).
+
  * http-backend was not listed in the command list in the documentation.
 
+ * Building on FreeBSD (both 7 and 8) needs OLD_ICONV set in the Makefile
+
+ * "git checkout -m some-branch" while on an unborn branch crashed.
+
 Other minor documentation updates are included.
