Changes 1.7.11:
UI, Workflows & Features
 * A new mode for push, "simple", which is a cross between \ 
"current"
   and "upstream", has been introduced. "git push" without \ 
any refspec
   will push the current branch out to the same name at the remote
   repository only when it is set to track the branch with the same
   name over there.  The plan is to make this mode the new default
   value when push.default is not configured.
 * A couple of commands learned the "--column" option to produce
   columnar output.
 * A third-party tool "git subtree" is distributed in contrib/
 * A remote helper that acts as a proxy and caches ssl session for the
   https:// transport is added to the contrib/ area.
 * Error messages given when @{u} is used for a branch without its
   upstream configured have been clarified.
 * Even with the "-q"uiet option, "checkout" used to report \ 
setting up
   tracking.  Also "branch" learned the "-q"uiet option to \ 
squelch
   informational message.
 * Your build platform may support hardlinks but you may prefer not to
   use them, e.g. when installing to DESTDIR to make a tarball and
   untarring on a filesystem that has poor support for hardlinks.
   There is a Makefile option NO_INSTALL_HARDLINKS for you.
 * The smart-http backend used to always override GIT_COMMITTER_*
   variables with REMOTE_USER and REMOTE_ADDR, but these variables are
   now preserved when set.
 * "git am" learned the "--include" option, which is an \ 
opposite of
   existing the "--exclude" option.
 * When "git am -3" needs to fall back to an application of the patch
   to a synthesized preimage followed by a 3-way merge, the paths that
   needed such treatment are now reported to the end user, so that the
   result in them can be eyeballed with extra care.
 * The output from "diff/log --stat" used to always allocate 4 columns
   to show the number of modified lines, but not anymore.
 * "git difftool" learned the "--dir-diff" option to spawn \ 
external
   diff tools that can compare two directory hierarchies at a time
   after populating two temporary directories, instead of running an
   instance of the external tool once per a file pair.
 * The "fmt-merge-msg" command learned to list the primary contributors
   involved in the side topic you are merging in a comment in the merge
   commit template.
 * "git rebase" learned to optionally keep commits that do not
   introduce any change in the original history.
 * "git push --recurse-submodules" learned to optionally look into the
   histories of submodules bound to the superproject and push them
   out.
 * A 'snapshot' request to "gitweb" honors If-Modified-Since: header,
   based on the commit date.
 * "gitweb" learned to highlight the patch it outputs even more.
