+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.

+GIT v1.6.2 Release Notes
+========================
+
+Updates since v1.6.1
+--------------------
+
+(subsystems)
+
+* git-svn updates.
+
+* gitweb updates, including a new patch view and RSS/Atom feed
+  improvements.
+
+(portability)
+
+(performance)
+
+* pack-objects autodetects the number of CPUs available and uses threaded
+  version.
+
+(usability, bells and whistles)
+
+* automatic typo correction works on aliases as well
+
+* @{-1} is a way to refer to the last branch you were on.  This is
+  accepted not only where an object name is expected, but anywhere
+  a branch name is expected.  E.g. "git branch --track mybranch @{-1}"
+  "git rev-parse --symbolic-full-name @{-1}".
+
+* "git add -p" learned 'g'oto action to jump directly to a hunk.
+
+* when "git am" stops upon a patch that does not apply, it shows the
+  title of the offending patch.
+
+* "git am --directory=<dir>" and "git am --reject" passes these options
+  to underlying "git apply".
+
+* "git clone" now makes its best effort when cloning from an empty
+  repository to set up configuration variables to refer to the remote
+  repository.
+
+* "git checkout -" is a shorthand for "git checkout @{-1}".
+
+* "git cherry" defaults to whatever the current branch is tracking (if
+  exists) when the <upstream> argument is not given.
+
+* "git cvsserver" can be told not to add extra "via git-CVS emulator" to
+  the commit log message it serves via gitcvs.commitmsgannotation
+  configuration.
+
+* "git diff" learned a new option --inter-hunk-context to coalesce close
+  hunks together and show context between them.
+
+* The definition of what constitutes a word for "git diff --color-words"
+  can be customized via gitattributes, command line or a configuration.
+
+* "git diff" learned --patience to run "patience diff" algorithm.
+
+* Some combinations of -b/-w/--ignore-space-at-eol to "git diff" did
+  not work as expected.
+
+* "git filter-branch" learned --prune-empty option that discards commits
+  that do not change the contents.
+
+* "git grep -w" and "git grep" for fixed strings have been optimized.
+
+* "git log" and friends include HEAD to the set of starting points
+  when --all is given.  This makes a difference when you are not on
+  any branch.
+
+* "git ls-tree" learned --full-tree option that shows the path in full
+  regardless of where in the work tree hierarchy the command was started.
+
+* "git mergetool" learned -y(--no-prompt) option to disable prompting.
+
+* "git rebase -i" can transplant a history down to root to elsewhere
+  with --root option.
+
+* "git reset --merge" is a new mode that works similar to the way
+  "git checkout" switches branches, taking the local changes while
+  switching to another commit.
+
+(internal)
+
+
+Fixes since v1.6.1
+------------------
+
+All of the fixes in v1.6.1.X maintenance series are included in this
+release, unless otherwise noted.
+
+* "git-add sub/file" when sub is a submodule incorrectly added the path to
+  the superproject.
+
+* git-bundle did not exclude annotated tags even when a range given from the
+  command line wanted to.
+
+* branch switching and merges had a silly bug that did not validate
+  the correct directory when making sure an existing subdirectory is
+  clean.

+Customizing word diff
+^^^^^^^^^^^^^^^^^^^^^
+
+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
+several such commands can be run together without intervening
+whitespace.  To separate them, use a regular expression such as
+
+------------------------
+[diff "tex"]
+       wordRegex = "\\\\[a-zA-Z]+|[{}]|\\\\.|[^\\{}[:space:]]+"

+A built-in pattern is provided for all languages listed in the
+previous section.

+git-difftool(1)
+===============
+
+NAME
+----
+git-difftool - compare changes using common merge tools
+
+SYNOPSIS
+--------
+'git difftool' [--tool=<tool>] [--no-prompt] ['git diff' options]
+
+DESCRIPTION
+-----------
+'git-difftool' is a git command that allows you to compare and edit files
+between revisions using common merge tools.  At its most basic level,
+'git-difftool' does what 'git-mergetool' does but its use is for non-merge
+situations such as when preparing commits or comparing changes against
+the index.
+
+'git difftool' is a frontend to 'git diff' and accepts the same
+arguments and options.
+
+See linkgit:git-diff[1] for the full list of supported options.
+
+OPTIONS
+-------
+-t <tool>::
+--tool=<tool>::
+       Use the merge resolution program specified by <tool>.
+       Valid merge tools are:
+       kdiff3, kompare, tkdiff, meld, xxdiff, emerge,
+       vimdiff, gvimdiff, ecmerge, and opendiff
++
+If a merge resolution program is not specified, 'git-difftool'
+will use the configuration variable `merge.tool`.  If the
+configuration variable `merge.tool` is not set, 'git difftool'
+will pick a suitable default.
++
+You can explicitly provide a full path to the tool by setting the
+configuration variable `mergetool.<tool>.path`. For example, you
+can configure the absolute path to kdiff3 by setting
+`mergetool.kdiff3.path`. Otherwise, 'git-difftool' assumes the
+tool is available in PATH.
++
+Instead of running one of the known merge tool programs,
+'git-difftool' can be customized to run an alternative program
+by specifying the command line to invoke in a configuration
+variable `mergetool.<tool>.cmd`.
++
+When 'git-difftool' is invoked with this tool (either through the
+`-t` or `--tool` option or the `merge.tool` configuration variable)
+the configured command line will be invoked with the following
+variables available: `$LOCAL` is set to the name of the temporary
+file containing the contents of the diff pre-image and `$REMOTE`
+is set to the name of the temporary file containing the contents
+of the diff post-image.  `$BASE` is provided for compatibility
+with custom merge tool commands and has the same value as `$LOCAL`.
+
+--no-prompt::
+       Do not prompt before launching a diff tool.
+
+CONFIG VARIABLES
+----------------
+merge.tool::
+       The default merge tool to use.
++
+See the `--tool=<tool>` option above for more details.
+
+merge.keepBackup::
+       The original, unedited file content can be saved to a file with
+       a `.orig` extension.  Defaults to `true` (i.e. keep the backup files).
+
+mergetool.<tool>.path::
+       Override the path for the given tool.  This is useful in case
+       your tool is not in the PATH.
+
+mergetool.<tool>.cmd::
+       Specify the command to invoke the specified merge tool.
++
+See the `--tool=<tool>` option above for more details.
+
+
+SEE ALSO
+--------
+linkgit:git-diff[1]::
+        Show changes between commits, commit and working tree, etc
+
+linkgit:git-mergetool[1]::
+       Run merge conflict resolution tools to resolve merge conflicts
+
+linkgit:git-config[1]::
+        Get and set repository or global options

+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.
