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. |
