+Git v1.7.4.2 Release Notes
+==========================
+
+Fixes since v1.7.4.1
+--------------------
+
+ * Many documentation updates to match "git cmd -h" output and the
+   git-cmd manual page.
+
+ * We used to keep one file descriptor open for each and every packfile
+   that we have a mmap window on it (read: "in use"), even when for very
+   tiny packfiles.  We now close the file descriptor early when the entire
+   packfile fits inside one mmap window.
+
+ * "git bisect visualize" tried to run "gitk" in windowing
+   environments even when "gitk" is not installed, resulting in a
+   strange error message.
+
+ * "git clone /no/such/path" did not fail correctly.
+
+ * "git commit" did not correctly error out when the user asked to use a
+   non existent file as the commit message template.
+
+ * "git diff --stat -B" ran on binary files counted the changes in lines,
+   which was nonsensical.
+
+ * "git diff -M" opportunistically detected copies, which was not
+   necessarily a good thing, especially when it is internally run by
+   recursive merge.
+
+ * "git difftool" didn't tell (g)vimdiff that the files it is reading are
+   to be opened read-only.
+
+ * "git merge" didn't pay attention to prepare-commit-msg hook, even
+   though if a merge is conflicted and manually resolved, the subsequent
+   "git commit" would have triggered the hook, which was inconsistent.
+
+ * "git patch-id" (and commands like "format-patch --ignore-in-upstream"
+   that use it as their internal logic) handled changes to files that end
+   with incomplete lines incorrectly.
+
+ * The official value to tell "git push" to push the current branch back
+   to update the upstream branch it forked from is now called "upstream".
+   The old name "tracking" is and will be supported.
+
+ * "git submodule update" used to honor the --merge/--rebase option (or
+   corresponding configuration variables) even for a newly cloned
+   subproject, which made no sense (so/submodule-no-update-first-time).
+
+ * gitweb's "highlight" interface mishandled tabs.
+
+ * gitweb didn't understand timezones with GMT offset that is not
+   multiple of a whole hour.
+
+ * gitweb had a few forward-incompatible syntactic constructs and
+   also used incorrect variable when showing the file mode in a diff.
+
+And other minor fixes and documentation updates.

+Git v1.7.4.3 Release Notes
+==========================
+
+Fixes since v1.7.4.2
+--------------------
+
+ * "git apply" used to confuse lines updated by previous hunks as lines
+   that existed before when applying a hunk, contributing misapplication
+   of patches with offsets.
+
+ * "git branch --track" (and "git checkout --track --branch") used to
+   allow setting up a random non-branch that does not make sense to follow
+   as the "upstream".  The command correctly diagnoses it as an error.
+
+ * "git checkout $other_branch" silently removed untracked symbolic links
+   in the working tree that are in the way in order to check out paths
+   under it from the named branch.
+
+ * "git cvsimport" did not bail out immediately when the cvs server cannot
+   be reached, spewing unnecessary error messages that complain about the
+   server response that it never got.
+
+ * "git diff --quiet" did not work very well with the "--diff-filter"
+   option.
+
+ * "git grep -n" lacked a long-hand synonym --line-number.
+
+ * "git stash apply" reported the result of its operation by running
+   "git status" from the top-level of the working tree; it should (and
+   now does) run it from the user's working directory.
+
+And other minor fixes and documentation updates.

+Git v1.7.4.4 Release Notes
+==========================
+
+Fixes since v1.7.4.3
+--------------------
+
+ * Compilation of sha1_file.c on BSD platforms were broken due to our
+   recent use of getrlimit() without including <sys/resource.h>.
+
+ * "git config" did not diagnose incorrect configuration variable names.
+
+ * "git format-patch" did not wrap a long subject line that resulted from
+   rfc2047 encoding.
+
+ * "git instaweb" should work better again with plackup.
+
+ * "git log --max-count=4 -Sfoobar" now shows 4 commits that changes the
+   number of occurrences of string "foobar"; it used to scan only for 4
+   commits and then emitted only matching ones.
+
+ * "git log --first-parent --boundary $c^..$c" segfaulted on a merge.
+
+ * "git pull" into an empty branch should have behaved as if
+   fast-forwarding from emptiness to the version being pulled, with
+   the usual protection against overwriting untracked files.
+
+ * "git submodule" that is run while a merge in the superproject is in
+   conflicted state tried to process each conflicted submodule up to
+   three times.
+
+ * "git status" spent all the effort to notice racily-clean index entries
+   but didn't update the index file to help later operations go faster in
+   some cases.
+
+And other minor fixes and documentation updates.

+Git v1.7.5 Release Notes
+========================
+
+Updates since v1.7.4
+--------------------
+
+ * Various MinGW portability fixes.
+
+ * Various git-p4 enhancements (in contrib).
+
+ * Various vcs-svn, git-svn and gitk enhancements and fixes.
+
+ * Various git-gui updates (0.14.0).
+
+ * Update to more modern HP-UX port.
+
+ * The codebase is getting prepared for i18n/l10n; no translated
+   strings nor translation mechanism in the code yet, but the strings
+   are being marked for l10n.
+
+ * The bash completion script can now complete symmetric difference
+   for "git diff" command, e.g. "git diff ...bra<TAB>".
+
+ * The default minimum length of abbreviated and unique object names
+   can now be configured by setting the core.abbrev configuration
+   variable.
+
+ * "git apply -v" reports offset lines when the patch does not apply at
+   the exact location recorded in the diff output.
+
+ * "git config" used to be also known as "git repo-config", but the old
+   name is now officially deprecated.
+
+ * "git checkout --detach <commit>" is a more user friendly synonym for
+   "git checkout <commit>^0".
+
+ * "git checkout" performed on detached HEAD gives a warning and
+   advice when the commit being left behind will become unreachable from
+   any branch or tag.
+
+ * "git cherry-pick" and "git revert" can be told to use a custom merge
+   strategy, similar to "git rebase".
+
+ * "git cherry-pick" remembers which commit failed to apply when it is
+   stopped by conflicts, making it unnecessary to use "commit -c $commit"
+   to conclude it.
+
+ * "git cvsimport" bails out immediately when the cvs server cannot be
+   reached, without spewing unnecessary error messages that complain about
+   the server response it never got.
+
+ * "git fetch" vs "git upload-pack" transfer learned 'no-done'
+   protocol extension to save one round-trip after the content
+   negotiation is done. This saves one HTTP RPC, reducing the overall
+   latency for a trivial fetch.
+
+ * "git fetch" can be told to recursively fetch submodules on-demand.
+
+ * "git grep -f <filename>" learned to treat "-" as "read from the
+   standard input stream".
+
+ * "git grep --no-index" did not honor pathspecs correctly, returning
+   paths outside the specified area.
+
+ * "git init" learned the --separate-git-dir option to allow the git
+   directory for a new repository created elsewhere and linked via the
+   gitdir mechanism. This is primarily to help submodule support later
+   to switch between a branch of superproject that has the submodule
+   and another that does not.
+
+ * "git log" type commands now understand globbing pathspecs.  You
+   can say "git log -- '*.txt'" for example.
+
+ * "git log" family of commands learned --cherry and --cherry-mark
+   options that can be used to view two diverged branches while omitting
+   or highlighting equivalent changes that appear on both sides of a
+   symmetric difference (e.g. "log --cherry A...B").
+
+ * A lazy "git merge" that didn't say what to merge used to be an error.
+   When run on a branch that has an upstream defined, however, the command
+   now merges from the configured upstream.
+
+ * "git mergetool" learned how to drive "beyond compare 3" as well.
+
+ * "git rerere forget" without pathspec used to forget all the saved
+   conflicts that relate to the current merge; it now requires you to
+   give it pathspecs.
+
+ * "git rev-list --objects $revs -- $pathspec" now limits the objects listed
+   in its output properly with the pathspec, in preparation for narrow
+   clones.
+
+ * "git push" with no parameters gives better advice messages when
+   "tracking" is used as the push.default semantics or there is no remote
+   configured yet.
+
+ * A possible value to the "push.default" configuration variable,
+   'tracking', gained a synonym that more naturally describes what it
+   does, 'upstream'.
+
+ * "git rerere" learned a new subcommand "remaining" that is similar to
+   "status" and lists the paths that had conflicts which are known to
+   rerere, but excludes the paths that have already been marked as
+   resolved in the index from its output.  "git mergetool" has been
+   updated to use this facility.
+
+Also contains various documentation updates.
+
+
+Fixes since v1.7.4
+------------------
+
+All of the fixes in the v1.7.4.X maintenance series are included in this
+release, unless otherwise noted.
+
+ * "git fetch" from a client that is mostly following the remote
+   needlessly told all of its refs to the server for both sides to
+   compute the set of objects that need to be transferred efficiently,
+   instead of stopping when the server heard enough. In a project with
+   many tags, this turns out to be extremely wasteful, especially over
+   the smart HTTP transport (sp/maint-{upload,fetch}-pack-stop-early~1).
+
+ * "git fetch" run from a repository that uses the same repository as
+   its alternate object store as the repository it is fetching from
+   did not tell the server that it already has access to objects
+   reachable from the refs in their common alternate object store,
+   causing it to fetch unnecessary objects (jc/maint-fetch-alt).
+
+ * "git remote add --mirror" created a configuration that is suitable for
+   doing both a mirror fetch and a mirror push at the same time, which
+   made little sense.  We now warn and require the command line to specify
+   either --mirror=fetch or --mirror=push.
