GIT v1.5.4 Release Notes
========================

Removal
-------

 * "git svnimport" was removed in favor of "git svn". It is still there
 in the source tree (contrib/examples) but unsupported.

 * As git-commit and git-status have been rewritten, "git runstatus"
 helper script lost all its users and has been removed.


Temporarily disabled
--------------------

 * "git http-push" is known not to work well with cURL library older
 than 7.16, and we had reports of repository corruption. It is
 disabled on such platforms for now. Unfortunately, 1.5.3.8 shares
 the same issue. In other words, this does not mean you will be
 fine if you stick to an older git release. For now, please do not
 use http-push from older git with cURL older than 7.16 if you
 value your data. A proper fix will hopefully materialize in
 later versions.


Deprecation notices
-------------------

 * From v1.6.0, git will by default install dashed form of commands
 (e.g. "git-commit") outside of users' normal $PATH, and will install
 only selected commands ("git" itself, and "gitk") in $PATH. This
 implies:

 - Using dashed forms of git commands (e.g. "git-commit") from the
 command line has been informally deprecated since early 2006, but
 now it officially is, and will be removed in the future. Use
 dash-less forms (e.g. "git commit") instead.

 - Using dashed forms from your scripts, without first prepending the
 return value from "git --exec-path" to the scripts' PATH, has been
 informally deprecated since early 2006, but now it officially is.

 - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
 PATH" early in your script is not deprecated with this change.

 Users are strongly encouraged to adjust their habits and scripts now
 to prepare for this change.

 * The post-receive hook was introduced in March 2007 to supersede
 the post-update hook, primarily to overcome the command line length
 limitation of the latter. Use of post-update hook will be deprecated
 in future versions of git, starting from v1.6.0.

 * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
 option, and will be removed in the future.

 * "git peek-remote" is deprecated, as "git ls-remote" was written in C
 and works for all transports; "git peek-remote" will be removed in
 the future.

 * "git repo-config" which was an old name for "git config" command
 has been supported without being advertised for a long time. The
 next feature release will remove it.

 * From v1.6.0, the repack.usedeltabaseoffset config option will default
 to true, which will give denser packfiles (i.e. more efficient storage).
 The downside is that git older than version 1.4.4 will not be able
 to directly use a repository packed using this setting.

 * From v1.6.0, the pack.indexversion config option will default to 2,
 which is slightly more efficient, and makes repacking more immune to
 data corruptions. Git older than version 1.5.2 may revert to version 1
 of the pack index with a manual "git index-pack" to be able to directly
 access corresponding pack files.


Updates since v1.5.3
--------------------

 * Comes with much improved gitk, with i18n.

 * Comes with git-gui 0.9.2 with i18n.

 * gitk is now merged as a subdirectory of git.git project, in
 preparation for its i18n.

 * progress displays from many commands are a lot nicer to the eye.
 Transfer commands show throughput data.

 * many commands that pay attention to per-directory .gitignore now do
 so lazily, which makes the usual case go much faster.

 * Output processing for '--pretty=format:<user format>' has been
 optimized.

 * Rename detection of diff family while detecting exact matches has
 been greatly optimized.

 * Rename detection of diff family tries to make more natural looking
 pairing. Earlier, if multiple identical rename sources were
 found in the preimage, the source used was picked pretty much at random.

 * Value "true" for color.diff and color.status configuration used to
 mean "always" (even when the output is not going to a terminal).
 This has been corrected to mean the same thing as "auto".

 * "git diff" Porcelain now respects diff.external configuration, which
 is another way to specify GIT_EXTERNAL_DIFF.

 * "git diff" can be told to use different prefixes other than
 "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".

 * "git diff" sometimes did not quote paths with funny
 characters properly.

 * "git log" (and any revision traversal commands) misbehaved
 when --diff-filter is given but was not asked to actually
 produce diff.

 * HTTP proxy can be specified per remote repository using
 remote.*.httpproxy configuration, or global http.proxy configuration
 variable.

 * Various Perforce importer updates.

 * Example update and post-receive hooks have been improved.

 * Any command that wants to take a commit object name can now use
 ":/string" syntax to name a commit.

 * "git reset" is now built-in and its output can be squelched with -q.

 * "git reset --hard" does not make any sense in a bare
 repository, but did not error out; fixed.

 * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.

 * "git rebase" learned --whitespace option.

 * In "git rebase", when you decide not to replay a particular change
 after the command stopped with a conflict, you can say "git rebase
 --skip" without first running "git reset --hard", as the command now
 runs it for you.

 * "git rebase --interactive" mode can now work on detached HEAD.

 * Other minor to serious bugs in "git rebase -i" have been fixed.

 * "git rebase" now detaches head during its operation, so after a
 successful "git rebase" operation, the reflog entry branch@{1} for
 the current branch points at the commit before the rebase was
 started.

 * "git rebase -i" also triggers rerere to help your repeated merges.

 * "git merge" can call the "post-merge" hook.

 * "git pack-objects" can optionally run deltification with multiple
 threads.

 * "git archive" can optionally substitute keywords in files marked with
 export-subst attribute.

 * "git cherry-pick" made a misguided attempt to repeat the original
 command line in the generated log message, when told to cherry-pick a
 commit by naming a tag that points at it. It does not anymore.

 * "git for-each-ref" learned %(xxxdate:<date-format>) syntax to show the
 various date fields in different formats.

 * "git gc --auto" is a low-impact way to automatically run a variant of
 "git repack" that does not lose unreferenced objects (read: safer
 than the usual one) after the user accumulates too many loose
 objects.

 * "git clean" has been rewritten in C.

 * You need to explicitly set clean.requireForce to "false" to allow
 "git clean" without -f to do any damage (lack of the configuration
 variable used to mean "do not require -f option to lose untracked
 files", but we now use the safer default).

 * The kinds of whitespace errors "git diff" and "git apply" notice (and
 fix) can be controlled via 'core.whitespace' configuration variable
 and 'whitespace' attribute in .gitattributes file.

 * "git push" learned --dry-run option to show what would happen if a
 push is run.

 * "git push" does not update a tracking ref on the local side when the
 remote refused to update the corresponding ref.

 * "git push" learned --mirror option. This is to push the local refs
 one-to-one to the remote, and deletes refs from the remote that do
 not exist anymore in the repository on the pushing side.

 * "git push" can remove a corrupt ref at the remote site with the usual
 ":ref" refspec.

 * "git remote" knows --mirror mode. This is to set up configuration to
 push into a remote repository to store local branch heads to the same
 branch on the remote side, and remove branch heads locally removed
 from local repository at the same time. Suitable for pushing into a
 back-up repository.

 * "git remote" learned "rm" subcommand.

 * "git cvsserver" can be run via "git shell". Also, "cvs" is
 recognized as a synonym for "git cvsserver", so that CVS users
 can be switched to git just by changing their login shell.

 * "git cvsserver" acts more like receive-pack by running post-receive
 and post-update hooks.

 * "git am" and "git rebase" are far less verbose.

 * "git pull" learned to pass --[no-]ff option to underlying "git
 merge".

 * "git pull --rebase" is a different way to integrate what you fetched
 into your current branch.

 * "git fast-export" produces data-stream that can be fed to fast-import
 to reproduce the history recorded in a git repository.

 * "git add -i" takes pathspecs to limit the set of files to work on.

 * "git add -p" is a short-hand to go directly to the selective patch
 subcommand in the interactive command loop and to exit when done.

 * "git add -i" UI has been colorized. The interactive prompt
 and menu can be colored by setting color.interactive
 configuration. The diff output (including the hunk picker)
 are colored with color.diff configuration.

 * "git commit --allow-empty" allows you to create a single-parent
 commit that records the same tree as its parent, overriding the usual
 safety valve.

 * "git commit --amend" can amend a merge that does not change the tree
 from its first parent.

 * "git commit" used to unconditionally strip comment lines that
 began with '#' and removed excess blank lines. This behavior has
 been made configurable.

 * "git commit" has been rewritten in C.

 * "git stash random-text" does not create a new stash anymore. It was
 a UI mistake. Use "git stash save random-text", or "git stash"
 (without extra args) for that.

 * "git stash clear extra-text" does not clear the whole stash
 anymore. It is tempting to expect "git stash clear stash@{2}"
 to drop only a single named stash entry, and it is rude to
 discard everything when that is asked (but not provided).

 * "git prune --expire <time>" can exempt young loose objects from
 getting pruned.

 * "git branch --contains <commit>" can list branches that are
 descendants of a given commit.

 * "git log" learned --early-output option to help interactive GUI
 implementations.

 * "git bisect" learned "skip" action to mark untestable commits.

 * "git bisect visualize" learned a shorter synonym "git bisect view".

 * "git bisect visualize" runs "git log" in a non-windowed
 environments. It also can be told what command to run (e.g. "git
 bisect visualize tig").

 * "git format-patch" learned "format.numbered" configuration variable
 to automatically turn --numbered option on when more than one commits
 are formatted.

 * "git ls-files" learned "--exclude-standard" to use the canned set of
 exclude files.

 * "git tag -a -f existing" begins the editor session using the existing
 annotation message.

 * "git tag -m one -m bar" (multiple -m options) behaves similarly to
 "git commit"; the parameters to -m options are formatted as separate
 paragraphs.

 * The format "git show" outputs an annotated tag has been updated to
 include "Tagger: " and "Date: " lines from the tag itself. Strictly
 speaking this is a backward incompatible change, but this is a
 reasonable usability fix and people's scripts shouldn't have been
 relying on the exact output from "git show" Porcelain anyway.

 * "git cvsimport" did not notice errors from underlying "cvsps"
 and produced a corrupt import silently.

 * "git cvsexportcommit" learned -w option to specify and switch to the
 CVS working directory.

 * "git checkout" from a subdirectory learned to use "../path" to allow
 checking out a path outside the current directory without cd'ing up.

 * "git checkout" from and to detached HEAD leaves a bit more
 information in the reflog.

 * "git send-email --dry-run" shows full headers for easier diagnosis.

 * "git merge-ours" is now built-in.

 * "git svn" learned "info" and "show-externals" subcommands.

 * "git svn" run from a subdirectory failed to read settings from the
 .git/config.

 * "git svn" learned --use-log-author option, which picks up more
 descriptive name from From: and Signed-off-by: lines in the commit
 message.

 * "git svn" wasted way too much disk to record revision mappings
 between svn and git; a new representation that is much more compact
 for this information has been introduced to correct this.

 * "git svn" left temporary index files it used without cleaning them
 up; this was corrected.

 * "git status" from a subdirectory now shows relative paths, which
 makes copy-and-pasting for git-checkout/git-add/git-rm easier. The
 traditional behavior to show the full path relative to the top of
 the work tree can be had by setting status.relativepaths
 configuration variable to false.

 * "git blame" kept text for each annotated revision in core needlessly;
 this has been corrected.

 * "git shortlog" learned to default to HEAD when the standard input is
 a terminal and the user did not give any revision parameter.

 * "git shortlog" learned "-e" option to show e-mail addresses as well as
 authors' names.

 * "git help" learned "-w" option to show documentation in browsers.

 * In addition there are quite a few internal clean-ups. Notably:

 - many fork/exec have been replaced with run-command API,
 brought from the msysgit effort.

 - introduction and more use of the option parser API.

 - enhancement and more use of the strbuf API.

 * Makefile tweaks to support HP-UX is in.

Fixes since v1.5.3
------------------

All of the fixes in v1.5.3 maintenance series are included in
this release, unless otherwise noted.

These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
series.

 * The way "git diff --check" behaves is much more consistent with the way
 "git apply --whitespace=warn" works.

 * "git svn" talking with the SVN over HTTP will correctly quote branch
 and project names.

 * "git config" did not work correctly on platforms that define
 REG_NOMATCH to an even number.

 * Recent versions of AsciiDoc 8 has a change to break our
 documentation; a workaround has been implemented.

 * "git diff --color-words" colored context lines in a wrong color.
