Git v1.7.9 Release Notes (draft)
========================

Updates since v1.7.8
--------------------

 * gitk updates accumulated since early 2011.

 * git-gui updated to 0.16.0.

 * git-p4 (in contrib/) updates.

 * Git uses gettext to translate its most common interface messages
   into the user's language if translations are available and the
   locale is appropriately set. Distributors can drop in new PO files
   in po/ to add new translations.

 * The code to handle username/password for HTTP transaction used in
   "git push" & "git fetch" learned to talk "credential API" to
   external programs to cache or store them, to allow integration with
   platform native keychain mechanisms.

 * The prompted input in the terminal use our own getpass() replacement
   when possible. HTTP transactions used to ask username without echoing
   back what was typed, but with this change you will see it as you type.

 * The internal of "revert/cherry-pick" has been tweaked to prepare
   building more generic "sequencer" on top of the implementation that
   drives them.

 * "git add" learned to stream large files directly into a packfile
   instead of writing them into individual loose object files.

 * "git checkout -B <current branch> <elsewhere>" is a more intuitive
   way to spell "git reset --keep <elsewhere>".

 * "git checkout" and "git merge" learned "--no-overwrite-ignore" option
   to tell Git that untracked and ignored files are not expendable.

 * "git commit --amend" learned "--no-edit" option to say that the
   user is amending the tree being recorded, without updating the
   commit log message.

 * "git commit" and "git reset" re-learned the optimization to prime
   the cache-tree information in the index, which makes it faster to
   write a tree object out after the index entries are updated.

 * "git commit" detects and rejects an attempt to stuff NUL byte in
   the commit log message.

 * "git commit" learned "-S" to GPG-sign the commit; this can be shown
   with the "--show-signature" option to "git log".

 * fsck and prune are relatively lengthy operations that still go
   silent while making the end-user wait. They learned to give progress
   output like other slow operations.

 * The set of built-in function-header patterns for various languages
   knows MATLAB.

 * "git log --format='<format>'" learned new %g[nNeE] specifiers to
   show information from the reflog entries when warlking the reflog
   (i.e. with "-g").

 * "git pull" can be used to fetch and merge an annotated/signed tag,
   instead of the tip of a topic branch. The GPG signature from the
   signed tag is recorded in the resulting merge commit for later
   auditing.

 * "git log" learned "--show-signature" option to show the signed tag
   that was merged that is embedded in the merge commit. It also can
   show the signature made on the commit with "git commit -S".

 * "git branch --edit-description" can be used to add descriptive text
   to explain what a topic branch is about.

 * "git fmt-merge-msg" learned to take the branch description into
   account when preparing a merge summary that "git merge" records
   when merging a local branch.

 * "git request-pull" has been updated to convey more information
   useful for integrators to decide if a topic is worth merging and
   what is pulled is indeed what the requestor asked to pull,
   including:

   - the tip of the branch being requested to be merged;
   - the branch description describing what the topic is about;
   - the contents of the annotated tag, when requesting to pull a tag.

 * "git pull" learned to notice 'pull.rebase' configuration variable,
   which serves as a global fallback for setting 'branch.<name>.rebase'
   configuration variable per branch.

 * "git tag" learned "--cleanup" option to control how the whitespaces
   and empty lines in tag message are cleaned up.

 * "gitweb" learned to show side-by-side diff.

Also contains minor documentation updates and code clean-ups.
