+GIT v1.6.2 Release Notes
+========================
+
+Updates since v1.6.1
+--------------------
+
+(subsystems)
+
+(portability)
+
+(performance)
+
+* pack-objects autodetects the number of CPUs available and uses threaded
+ version.
+
+(usability, bells and whistles)
+
+* "git-add -p" learned 'g'oto action to jump directly to a hunk.
+
+* git-cherry defaults to HEAD 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.
+
+* git-filter-branch learned --prune-empty option that discards commits
+ that do not change the contents.
+
+* 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-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.
+
+* git-grep did not work correctly for index entries with assume-unchanged bit.
+
+* branch switching and merges had a silly bug that did not validate
+ the correct directory when making sure an existing subdirectory is
+ clean.

SYNOPSIS
--------
-'git cherry' [-v] <upstream> [<head>] [<limit>]
+'git cherry' [-v] [<upstream> [<head> [<limit>]]]
DESCRIPTION
-----------
<upstream>::
Upstream branch to compare against.
+ Defaults to the first tracked remote branch, if available.
<head>::
Working branch; defaults to HEAD.
v1.0.4-14-g2414721
i.e. the current head of my "parent" branch is based on v1.0.4,
-but since it has a handful commits on top of that,
+but since it has a few commits on top of that,
describe has added the number of additional commits ("14") and

at the end.
convenience functions, too. For example, calling 'skip_commit "$@"'
will leave out the current commit (but not its changes! If you want
that, use 'git-rebase' instead).
++
+You can also use the 'git_commit_non_empty_tree "$@"' instead of
+'git commit-tree "$@"' if you don't wish to keep commits with a single parent
+and that makes no change to the tree.
--tag-name-filter <command>::
This is the filter for rewriting tag names. When passed,
The result will contain that directory (and only that) as its
project root.
+--prune-empty::
+ Some kind of filters will generate empty commits, that left the tree
+ untouched. This switch allow git-filter-branch to ignore such
+ commits. Though, this switch only applies for commits that have one
+ and only one parent, it will hence keep merges points. Also, this
+ option is not compatible with the use of '--commit-filter'. Though you
+ just need to use the function 'git_commit_non_empty_tree "$@"' instead
+ of the 'git commit-tree "$@"' idiom in your commit filter to make that
+ happen.
+
--original <namespace>::
Use this option to set the namespace where the original commits
will be stored. The default value is 'refs/original'.
--abbrev[=<n>]::
Instead of showing the full 40-byte hexadecimal object
- lines, show only handful hexdigits prefix.

DESCRIPTION
'sub/dir' in 'HEAD'). You don't want to give a tree that is not at the
root level (e.g. 'git ls-tree -r HEAD:sub dir') in this case, as that
would result in asking for 'sub/sub/dir' in the 'HEAD' commit.

+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[7] 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, 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`.
