I tagged the tip of 'master' as 1.5.3-rc0; in addition to the
topics described in the latest "What's in", most of the topics
that have been cooking in 'next' are there. The time some of
them have spent before going to 'master' might be shorter than
usual and there are a handful patches that I took directly to
'master', but the tip of 'master' should be as solid as usual.
There probably could be a few bits that we have already seen and
was reviewed on the list that deserve to be in v1.5.3 (the only
ones I have in mind right now are a few gitweb ones), but other
than that, I think this is pretty much it, modulo bugfixes.
Oh, by the way, a maintenance release 1.5.2.3 is also out.

GIT v1.5.3 Release Notes (draft as of -rc0)
========================
Updates since v1.5.2
--------------------
* The commit walkers other than http are officially deprecated
(but still supported).
* The submodule support has Porcelain layer now.
* 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.
* For people who need to import from Perforce, a front-end for
fast-import is in contrib/fast-import/ now.
* Comes with git-gui 0.8.0.
* Comes with updated gitk.
* New commands and options.
- "git stash" allows you to quickly save away your work in
progress and replay it later on an updated state.
- "git rebase" learned an "interactive" mode.
- "git fsck" can save its findings in lost-found, without a
separate invocation of "git lost-found" command.
- GIT_WORK_TREE environment variable can be used together with
GIT_DIR to work in a subdirectory of a working tree that is
not located at "$GIT_DIR/..".
- "git log" learned a new option '--follow', to follow
renaming history of a single file.
- "git-filter-branch" is a reborn cg-admin-rewritehist.
- "git-cvsserver" learned new options (--base-path, --export-all,
--strict-paths) inspired by git-daemon.
- "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".
- "git fsck" gained --verbose option. This is really really
verbose but it might help you identify exact commit that is
corrupt in your repository.
- "git format-patch" learned --numbered-files option. This
may be useful for MH users.
- "git format-patch" learned format.subjectprefix
configuration variable, which serves the same purpose as the
existing --subject-prefix option.
- "git tag -n -l" shows tag annotations while listing tags.
- "git cvsimport" can optionally use the separate-remote layout.
- "git blame" can be told to see through commits that changes
whitespaces and indentation levels with "-w" option.
- "git send-email" can be told not to thread the messages when
sending out more than one patches.
- "git config" learned NUL terminated output format via -z to
help scripts.
- "git init -q" makes it quieter.
* Updated behavior of existing commands.
- "git svn dcommit" retains local merge information.
- "git config" to set values also honor type flags like --bool
and --int.
- core.quotepath configuration can be used to make textual git
output to emit most of the characters in the path literally.
- "git mergetool" chooses its backend more wisely, taking
notice of its environment such as use of X, Gnome/KDE, etc.
- "gitweb" shows merge commits a lot nicer than before. The
default view uses more compact --cc format, while the UI
allows to choose normal diff with any parent.
- snapshot files "gitweb" creates from a repository at
$path/$project/.git are more useful. We use $project part
in the filename, which we used to discard.
- "git cvsimort" creates lightweight tag; there is not any
interesting information we can record in an annotated tag,
and the handcrafted ones the old code created was not
properly formed anyway.
- "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.
- "git-fetch" over git native protocols with -v shows connection
status, and the IP address of the other end, to help
diagnosing problems.
- We used to have core.legacyheaders configuration, when
set to false, allowed git to write loose objects in a format
that mimicks the format used by objects stored in packs. It
turns out that this was not so useful. Although we will
continue to read objects written in that format, we do not
honor that configuration anymore and create loose objects in
the legacy/traditional format.
- "--find-copies-harder" option to diff family can now be
spelled as "-C -C" for brevity.
- "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.
- "git-mergetool" learned to use gvimdiff.
- "gitview" (in contrib) has a better blame interface.
- "git log" and friends did not handle a commit log message
that is larger than 16kB; they do now.
- "--pretty=oneline" output format for "git log" and friends
deals with "malformed" commit log messages that have more
than one lines in the first paragraph better. We used to
show the first line, cutting the title at mid-sentence; we
concatenate them into a single line and treat the result as
"oneline".
* Builds
- old-style function definitions (most notably, a function
without parameter defined with "func()", not "func(void)")
have been eradicated.
* 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.
- verifying pack contents done by "git fsck --full" got boost
by carefully choosing the order to verify objects in them.
Fixes since v1.5.2
------------------
All of the fixes in v1.5.2 maintenance series are included in
this release, unless otherwise noted.
* Bugfixes
- "gitweb" had trouble handling non UTF-8 text with older
Encode.pm Perl module.
