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.
