+Git v1.7.8 Release Notes
+========================
+
+Updates since v1.7.7
+--------------------
+
+ * Some git-svn, git-gui, git-p4 (in contrib) and msysgit updates.
+
+ * Updates to bash completion scripts.
+
+ * The build procedure has been taught to take advantage of computed
+   dependency automatically when the compiler supports it.
+
+ * The date parser now accepts timezone designators that lack minutes
+   part and also has a colon between "hh:mm".
+
+ * The contents of the /etc/mailname file, if exists, is used as the
+   default value of the hostname part of the committer/author e-mail.
+
+ * "git am" learned how to read from patches generated by Hg.
+
+ * "git archive" talking with a remote repository can report errors
+   from the remote side in a more informative way.
+
+ * "git branch" learned an explicit --list option to ask for branches
+   listed, optionally with a glob matching pattern to limit its output.
+
+ * "git check-attr" learned "--cached" option to look at .gitattributes
+   files from the index, not from the working tree.
+
+ * Variants of "git cherry-pick" and "git revert" that take multiple
+   commits learned to "--continue" and "--abort".
+
+ * "git daemon" gives more human readable error messages to clients
+   using ERR packets when appropriate.
+
+ * Errors at the network layer is logged by "git daemon".
+
+ * "git diff" learned "--minimal" option to spend extra cycles to come
+   up with a minimal patch output.
+
+ * "git diff" learned "--function-context" option to show the whole
+   function as context that was affected by a change.
+
+ * "git difftool" can be told to skip launching the tool for a path by
+   answering 'n' to its prompt.
+
+ * "git fetch" learned to honor transfer.fsckobjects configuration to
+   validate the objects that were received from the other end, just like
+   "git receive-pack" (the receiving end of "git push") does.
+
+ * "git fetch" makes sure that the set of objects it received from the
+   other end actually completes the history before updating the refs.
+   "git receive-pack" (the receiving end of "git push") learned to do the
+   same.
+
+ * "git fetch" learned that fetching/cloning from a regular file on the
+   filesystem is not necessarily a request to unpack a bundle file; the
+   file could be ".git" with "gitdir: <path>" in it.
+
+ * "git for-each-ref" learned "%(contents:subject)", "%(contents:body)"
+   and "%(contents:signature)". The last one is useful for signed tags.
+
+ * "git grep" used to incorrectly pay attention to .gitignore files
+   scattered in the directory it was working in even when "--no-index"
+   option was used. It no longer does this. The "--exclude-standard"
+   option needs to be given to explicitly activate the ignore
+   mechanism.
+
+ * "git grep" learned "--untracked" option, where given patterns are
+    searched in untracked (but not ignored) files as well as tracked
+    files in the working tree, so that matches in new but not yet
+    added files do not get missed.
+
+ * The recursive merge backend no longer looks for meaningless
+   existing merges in submodules unless in the outermost merge.
+
+ * "git log" and friends learned "--children" option.
+
+ * "git ls-remote" learned to respond to "-h"(elp) requests.
+
+ * "mediawiki" remote helper can interact with (surprise!) MediaWiki
+   with "git fetch" & "git push".
+
+ * "git merge" learned the "--edit" option to allow users to edit the
+   merge commit log message.
+
+ * "git rebase -i" can be told to use special purpose editor suitable
+   only for its insn sheet via sequence.editor configuration variable.
+
+ * "git send-email" learned to respond to "-h"(elp) requests.
+
+ * "git send-email" allows the value given to sendemail.aliasfile to begin
+   with "~/" to refer to the $HOME directory.
+
+ * "git send-email" forces use of Authen::SASL::Perl to work around
+   issues between Authen::SASL::Cyrus and AUTH PLAIN/LOGIN.
+
+ * "git stash" learned "--include-untracked" option to stash away
+   untracked/ignored cruft from the working tree.
+
+ * "git submodule clone" does not leak an error message to the UI
+   level unnecessarily anymore.
+
+ * "git submodule update" learned to honor "none" as the value for
+   submodule.<name>.update to specify that the named submodule should
+   not be checked out by default.
+
+ * When populating a new submodule directory with "git submodule init",
+   the $GIT_DIR metainformation directory for submodules is created inside
+   $GIT_DIR/modules/<name>/ directory of the superproject and referenced
+   via the gitfile mechanism. This is to make it possible to switch
+   between commits in the superproject that has and does not have the
+   submodule in the tree without re-cloning.
+
+ * "gitweb" leaked unescaped control characters from syntax hiliter
+   outputs.
+
+ * "gitweb" can be told to give custom string at the end of the HTML
+   HEAD element.
+
+ * "gitweb" now has its own manual pages.
+
+
+Also contains other documentation updates and minor code cleanups.
+
+
+Fixes since v1.7.7
+------------------
+
+Unless otherwise noted, all fixes in the 1.7.7.X maintenance track are
+included in this release.
+
+ * HTTP transport did not use pushurl correctly, and also did not tell
+   what host it is trying to authenticate with when asking for
+   credentials.
+   (merge deba493 jk/http-auth later to maint).
+
+ * "git blame" was aborted if started from an uncommitted content and
+   the path had the textconv filter in effect.
+   (merge 8518088 ss/blame-textconv-fake-working-tree later to maint).
+
+ * Adding many refs to the local repository in one go (e.g. "git fetch"
+   that fetches many tags) and looking up a ref by name in a repository
+   with too many refs were unnecessarily slow.
+   (merge 17d68a54d jp/get-ref-dir-unsorted later to maint).
+
+ * Report from "git commit" on untracked files was confused under
+   core.ignorecase option.
+   (merge 395c7356 jk/name-hash-dirent later to maint).
+
+ * "git merge" did not understand ":/<pattern>" as a way to name a commit.
+
+ " "git push" on the receiving end used to call post-receive and post-update
+   hooks for attempted removal of non-existing refs.
+   (merge 160b81ed ph/push-to-delete-nothing later to maint).
+
+ * Help text for "git remote set-url" and "git remote set-branches"
+   were misspelled.
+   (merge c49904e fc/remote-seturl-usage-fix later to maint).
+   (merge 656cdf0 jc/remote-setbranches-usage-fix later to maint).
