+GIT v1.6.1.2 Release Notes
+==========================
+
+Fixes since v1.6.1.1
+--------------------
+
+* The logic for rename detectin in internal diff used by commands like
+ "git diff" and "git blame" have been optimized to avoid loading the same
+ blob repeatedly.
+
+* We did not allow writing out a blob that is larger than 2GB for no good
+ reason.
+
+* "git format-patch -o $dir", when $dir is a relative directory, used it
+ as relative to the root of the work tree, not relative to the current
+ directory.
+
+* v1.6.1 introduced an optimization for "git push" into a repository (A)
+ that borrows its objects from another repository (B) to avoid sending
+ objects that are available in repository B, when they are not yet used
+ by repository A. However the code on the "git push" sender side was
+ buggy and did not work when repository B had new objects that are not
+ known by the sender. This caused pushing into a "forked" repository
+ served by v1.6.1 software using "git push" from v1.6.1 sometimes did not
+ work. The bug was purely on the "git push" sender side, and has been
+ corrected.
+
+* "git status -v" did not paint its diff output in colour even when
+ color.ui configuration was set.
+
+* "git ls-tree" learned --full-tree option to help Porcelain scripts that
+ want to always see the full path regardless of the current working
+ directory.
+
+* "git grep" incorrectly searched in work tree paths even when they are
+ marked as assume-unchanged. It now searches in the index entries.
+
+* "git gc" with no grace period needlessly ejected packed but unreachable
+ objects in their loose form, only to delete them right away.

+^^^^^^^^^^^^^^^^^^^^^
+
+You can customize the rules that `git diff --color-words` uses to
+split words in a line, by specifying an appropriate regular expression
+in the "diff.*.wordRegex" configuration variable. For example, in TeX
+a backslash followed by a sequence of letters forms a command, but

$home_link = "/";
+PATH_INFO usage
+-----------------------
+If you enable PATH_INFO usage in gitweb by putting
+
+ $feature{'pathinfo'}{'default'} = [1];
+
+in your gitweb.conf, it is possible to set up your server so that it
+consumes and produces URLs in the form
+
+http://git.example.com/project.git/shortlog/sometag
+
+by using a configuration such as the following, that assumes that
+/var/www/gitweb is the DocumentRoot of your webserver, and that it
+contains the gitweb.cgi script and complementary static files
+(stylesheet, favicon):
+
+<VirtualHost *:80>
+ ServerAlias git.example.com
+
+ DocumentRoot /var/www/gitweb
+
+ <Directory /var/www/gitweb>
+ Options ExecCGI
+ AddHandler cgi-script cgi
+
+ DirectoryIndex gitweb.cgi
+
+ RewriteEngine On
+ RewriteCond %{REQUEST_FILENAME} !-f
+ RewriteCond %{REQUEST_FILENAME} !-d
+ RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+ </Directory>
+</VirtualHost>
+
+The rewrite rule guarantees that existing static files will be properly
+served, whereas any other URL will be passed to gitweb as PATH_INFO
+parameter.
+
+Notice that in this case you don't need special settings for
+@stylesheets, $my_uri and $home_link, but you lose "dumb client" access
+to your project .git dirs. A possible workaround for the latter is the
+following: in your project root dir (e.g. /pub/git) have the projects
+named without a .git extension (e.g. /pub/git/project instead of
+/pub/git/project.git) and configure Apache as follows:
+
+<VirtualHost *:80>
+ ServerAlias git.example.com
+
+ DocumentRoot /var/www/gitweb
+
+ AliasMatch ^(/.*?)(\.git)(/.*)? /pub/git$1$3
+ <Directory /var/www/gitweb>
+ Options ExecCGI
+ AddHandler cgi-script cgi
+
+ DirectoryIndex gitweb.cgi
+
+ RewriteEngine On
+ RewriteCond %{REQUEST_FILENAME} !-f
+ RewriteCond %{REQUEST_FILENAME} !-d
+ RewriteRule ^.* /gitweb.cgi/$0 [L,PT]
+ </Directory>
+</VirtualHost>
+
+The additional AliasMatch makes it so that
+
+http://git.example.com/project.git
+
+will give raw access to the project's git dir (so that the project can
+be cloned), while
+
+http://git.example.com/project
+
+will provide human-friendly gitweb access.
