GIT v1.5.2 Release Notes (draft)
========================
 
Updates since v1.5.1
--------------------
 
* Plumbing level subproject support.
 
  You can include a subdirectory that has an independent git
  repository in your index and tree objects as a
  "subproject".  This plumbing (i.e. "core") level subproject
  support explicitly excludes recursive behaviour.
 
  The "subproject" entries in the index and trees are
  incompatible with older versions of git.  Experimenting with
  the plumbing level support is encouraged, but be warned that
  unless everybody in your project updates to this release or
  later, using this feature would make your project
  inaccessible by people with older versions of git.
 
* Plumbing level gitattributes support.
 
  The gitattributes mechanism allows you to add 'attributes' to
  paths in your project, and affect the way certain git
  operations work.  Currently you can influence if a path is
  considered a binary or text (the former would be treated by
  'git diff' not to produce textual output; the latter can go
  through the line endings conversion process in repositories
  with core.autocrlf set), and specify a custom 3-way merge
  driver.
 
* The packfile format now optionally suports 64-bit index.
 
  This release supports the "version 2" format of the .idx
  file.  This is automatically enabled when a huge packfile
  needs more than 32-bit to express offsets of objects in the
  pack
 
* New commands and options.
 
  - "git bisect start" can optionally take a single bad commit and
    zero or more good commits on the command line.
 
  - "git shortlog" can optionally be told to wrap its output.
 
  - "subtree" merge strategy allows another project to be merged in as
    your subdirectory.
 
  - "git format-patch" learned a new --subject-prefix=<string>
    option, to override the built-in "[PATCH]".
 
  - "git add -u" is a quick way to do the first stage of "git
    commit -a" (i.e. update the index to match the working
    tree); it obviously does not make a commit.
 
* Updated behavior of existing commands.
 
  - "git diff --stat" shows size of preimage and postimage blobs
    for binary contents.  Earlier it only said "Bin".
 
  - "git lost-found" shows stuff that are unreachable except
    from reflogs.
 
  - "git checkout branch^0" now detaches HEAD at the tip commit
    on the named branch, instead of just switching to the
    branch (use "git checkout branch" to switch to the branch,
    as before).
 
  - "git bisect next" can be used after giving only a bad commit
    without giving a good one (this starts bisection half-way to
    the root commit).  We used to refuse to operate without a
    good and a bad commit.
 
  - "git push", when pushing into more than one repository, does
    not stop at the first error.
 
  - "git archive" does not insist you to give --format parameter
    anymore; it defaults to "tar".
 
  - "git cvsserver" can use backends other than sqlite.
 
  - "gitview" (in contrib/ section) learned to better support
    "git-annotate".
 
  - Local "git fetch" from a repository whose object store is
    one of the alternates (e.g. fetching from the origin in a
    repository created with "git clone -l -s") avoids
    downloading objects unnecessary.
 
* Builds
 
  - git-p4import has never been installed; now there is an
    installation option to do so.
 
  - gitk and git-gui can be configured out.
 
  - Generated documentation pages automatically get version
    information from GIT_VERSION
 
  - Parallel build with "make -j" descending into subdirectory
    was fixed.
 
* Performance Tweaks
 
  - optimized "git-rev-list --bisect" (hence "git-bisect").
 
  - optimized "git-add $path" in a large directory, most of
    whose contents are ignored.
 
 
Fixes since v1.5.1
------------------
 
All of the fixes in v1.5.1 maintenance series are included in
this release, unless otherwise noted.
 
* Bugfixes
 
  - Switching branches with "git checkout" refused to work when
    a path changes from a file to a directory between the
    current branch and the new branch, in order not to lose
    possible local changes in the directory that is being turned
    into a file with the switch.  We now allow such a branch
    switch after making sure that there is no locally modified
    file nor un-ignored file in the directory.  This has not
    been backported to 1.5.1.x series, as it is rather an
    intrusive change.
 
  - Merging branches that have a file in one and a directory in
    another at the same path used to get quite confused.  We
    handle such a case a bit more carefully, even though that is
    still left as a conflict for the user to sort out.  This
    will not be backported to 1.5.1.x series, as it is rather an
    intrusive change.
 
* Documentation updates
 
* Performance Tweaks
