 All of the fixes in v1.6.5.X maintenance series are included in this
 release, unless otherwise noted.
 
- * "git apply" and "git diff" (including patch output from "git log -p")
-   now flags trailing blank lines as whitespace errors correctly (only
-   "apply --whitespace=fix" stripped them but "apply --whitespace=warn"
-   did not even warn).
-
- * Two whitespace error classes, 'blank-at-eof' and 'blank-at-eol', have
-   been introduced (settable by core.whitespace configuration variable and
-   whitespace attribute).  The 'trailing-space' whitespace error class has
-   become a short-hand to cover both of these and there is no behaviour
-   change for existing set-ups.
-
- * "git cvsimport" did not work well when it is fed filenames from the
-   command line and is not started at the top of the work tree.  We should
-   backport this by merging f6fdbb6 (cvsimport: fix relative argument
-   filenames, 2009-10-19).
-
- * The way gitweb escapes its CGI parameters were broken especially when
-   the parameter was a UTF-8 string.  We may want to backport this to
-   1.6.5.X series by merging 452e225 (gitweb: fix esc_param, 2009-10-13).
-
- * gitweb used to show 'patch' link for merge commits but the output from
-   it is not usable to feed "git am" with.  We may want to backport this
-   to 1.6.5.X series by merging 1655c98 (gitweb: Do not show 'patch' link
-   for merge commits, 2009-10-09).
