GIT v1.5.3 Release Notes (draft)
========================

Updates since v1.5.2
--------------------

* An initial interation of Porcelain level superproject support
  started to take shape.

* Thee are a handful pack-objects changes to help you cope better with
  repositories with pathologically large blobs in them.

* New commands and options.

  - "git-submodule" command helps you manage the projects from
    the superproject that contain them.

  - In addition to core.compression configuration option,
    core.loosecompression and pack.compression options can
    independently tweak zlib compression levels used for loose
    and packed objects.

  - "git-ls-tree -l" shows size of blobs pointed at by the
    tree entries, similar to "/bin/ls -l".

  - "git-rev-list" learned --regexp-ignore-case and
    --extended-regexp options to tweak its matching logic used
    for --grep fitering.

  - "git-describe --contains" is a handier way to call more
    obscure command "git-name-rev --tags".

  - "git gc --aggressive" tells the command to spend more cycles
    to optimize the repository harder.

  - "git repack" can be told to split resulting packs to avoid
    exceeding limit specified with "--max-pack-size".

* Updated behavior of existing commands.

  - "git push" pretends that you immediately fetched back from
    the remote by updating corresponding remote tracking
    branches if you have any.

  - The diffstat given after a merge (or a pull) honors the
    color.diff configuration.

  - "git-apply --whitespace=strip" removes blank lines added at
    the end of the file.

  - fetch over git native protocols with -v shows connection
    status, and the IP address of the other end, to help
    diagnosing problems.

  - core.legacyheaders is no more, although we still can read
    objects created in a new loose object format.

  - "git-mailsplit" (hence "git-am") can read from Maildir
    formatted mailboxes.

  - "git cvsserver" does not barf upon seeing "cvs login"
    request.

  - "pack-objects" honors "delta" attribute set in
    .gitattributes.  It does not attempt to deltify blobs that
    come from paths with delta attribute set to false.

  - new-workdir script (in contrib) can now be used with a bare
    repository.


* Builds

  -

* Performance Tweaks

  - git-pack-objects avoids re-deltification cost by caching
    small enough delta results it creates while looking for the
    best delta candidates.

  - diff-delta code that is used for packing has been improved
    to work better on big files.

  - when there are more than one pack files in the repository,
    the runtime used to try finding an object always from the
    newest packfile; it now tries the same packfile as we found
    the object requested the last time, which exploits the
    locality of references.

Fixes since v1.5.2
------------------

All of the fixes in v1.5.2 maintenance series are included in
this release, unless otherwise noted.

* Bugfixes

  - ....  This has not
    been backported to 1.5.2.x series, as it is rather an
    intrusive change.
