   1 GIT v1.5.4 Release Notes
   2 ========================
   3
   4 Removal
   5 -------
   6
   7  * "git svnimport" was removed in favor of "git svn".  It is still there
   8    in the source tree (contrib/examples) but unsupported.
   9
  10  * As git-commit and git-status have been rewritten, "git runstatus"
  11    helper script lost all its users and has been removed.
  12
  13
  14 Deprecation notices
  15 -------------------
  16
  17  * The next feature release of git (this change is scheduled for v1.6.0)
  18    will by default install dashed form of commands (e.g. "git-commit")
  19    outside of users' normal $PATH, and will install only selected
  20    commands ("git" itself, and "gitk") in $PATH.  This implies:
  21
  22    - Using dashed forms of git commands (e.g. "git-commit") from the
  23      command line has been informally deprecated since early 2006, but
  24      now it officially is, and will be removed in the future.  Use
  25      dashless forms (e.g. "git commit") instead.
  26
  27    - Using dashed forms from your scripts, without first prepending the
  28      return value from "git --exec-path" to the scripts' PATH, has been
  29      informally deprecated since early 2006, but now it officially is.
  30
  31    - Use of dashed forms with "PATH=$(git --exec-path):$PATH; export
  32      PATH" early in your script is not deprecated with this change.
  33
  34   Users are strongly encouraged to adjust their habits and scripts now
  35   to prepare for this.
  36
  37  * The post-receive hook was introduced in March 2007 to supersede
  38    the post-update hook, primarily to overcome the command line length
  39    limitation of the latter.  Use of post-update hook will be deprecated
  40    in future versions of git, starting from v1.6.0.
  41
  42  * "git lost-found" was deprecated in favor of "git fsck"'s --lost-found
  43    option, and will be removed in the future.
  44
  45  * "git peek-remote" is deprecated, as "git ls-remote" was written in C
  46    and works for all transports; "git peek-remote" will be removed in
  47    the future.
  48
  49  * From v1.6.0, the repack.usedeltabaseoffset config option will default
  50    to true, which will give denser packfiles (i.e. more efficient storage).
  51    The downside is that git older than version 1.4.4 will not be able
  52    to directly use a repository packed using this setting.
  53
  54  * From v1.6.0, the pack.indexversion config option will default to 2,
  55    which is slightly more efficient, and makes repacking more immune to
  56    data corruptions.  Git older than version 1.5.2 may revert to version 1
  57    of the pack index with a manual "git index-pack" to be able to directly
  58    access corresponding pack files.
  59
  60
  61 Updates since v1.5.3
  62 --------------------
  63
  64  * Comes with much improved gitk.
  65
  66  * Comes with "git gui" 0.9.1 with i18n.
  67
  68  * gitk is now merged as a subdirectory of git.git project, in
  69    preparation for its i18n.
  70
  71  * progress displays from many commands are a lot nicer to the eye.
  72    Transfer commands show throughput data.
  73
  74  * many commands that pay attention to per-directory .gitignore now do
  75    so lazily, which makes the usual case go much faster.
  76
  77  * Output processing for '--pretty=format:<user format>' has been
  78    optimized.
  79
  80  * Rename detection of diff family while detecting exact matches has
  81    been greatly optimized.
  82
  83  * Rename detection of diff family tries to make more natural looking
  84    pairing.  Earlier, if multiple identical rename sources were
  85    found in the preimage, the source used was picked pretty much at random.
  86
  87  * Value "true" for color.diff and color.status configuration used to
  88    mean "always" (even when the output is not going to a terminal).
  89    This has been corrected to mean the same thing as "auto".
  90
  91  * "git diff" Porcelain now respects diff.external configuration, which
  92    is another way to specify GIT_EXTERNAL_DIFF.
  93
  94  * "git diff" can be told to use different prefixes other than
  95    "a/" and "b/" e.g. "git diff --src-prefix=l/ --dst-prefix=k/".
  96
  97  * "git diff" sometimes did not quote paths with funny
  98    characters properly.
  99
 100  * "git log" (and any revision traversal commands) misbehaved
 101    when --diff-filter is given but was not asked to actually
 102    produce diff.
 103
 104  * HTTP proxy can be specified per remote repository using
 105    remote.*.httpproxy configuration, or global http.proxy configuration
 106    variable.
 107
 108  * Various Perforce importer updates.
 109
 110  * Example update and post-receive hooks have been improved.
 111
 112  * Any command that wants to take a commit object name can now use
 113    ":/string" syntax to name a commit.
 114
 115  * "git reset" is now built-in and its output can be squelched with -q.
 116
 117  * "git reset --hard" does not make any sense in a bare
 118    repository, but did not error out; fixed.
 119
 120  * "git send-email" can optionally talk over ssmtp and use SMTP-AUTH.
 121
 122  * "git rebase" learned --whitespace option.
 123
 124  * In "git rebase", when you decide not to replay a particular change
 125    after the command stopped with a conflict, you can say "git rebase
 126    --skip" without first running "git reset --hard", as the command now
 127    runs it for you.
 128
 129  * "git rebase --interactive" mode can now work on detached HEAD.
 130
 131  * Other minor to serious bugs in "git rebase -i" have been fixed.
 132
 133  * "git rebase" now detaches head during its operation, so after a
 134    successful "git rebase" operation, the reflog entry branch@{1} for
 135    the current branch points at the commit before the rebase was
 136    started.
 137
 138  * "git rebase -i" also triggers rerere to help your repeated merges.
 139
 140  * "git merge" can call the "post-merge" hook.
 141
 142  * "git pack-objects" can optionally run deltification with multiple
 143    threads.
 144
 145  * "git archive" can optionally substitute keywords in files marked with
 146    export-subst attribute.
 147
 148  * "git cherry-pick" made a misguided attempt to repeat the original
 149    command line in the generated log message, when told to cherry-pick a
 150    commit by naming a tag that points at it.  It does not anymore.
 151
 152  * "git for-each-ref" learned %(xxxdate:<dateformat>) syntax to show the
 153    various date fields in different formats.
 154
 155  * "git gc --auto" is a low-impact way to automatically run a variant of
 156    "git repack" that does not lose unreferenced objects (read: safer
 157    than the usual one) after the user accumulates too many loose
 158    objects.
 159
 160  * "git clean" has been rewritten in C.
 161
 162  * You need to explicitly set clean.requireForce to "false" to allow
 163    "git clean" without -f to do any damage (lack of the configuration
 164    variable used to mean "do not require -f option to lose untracked
 165    files", but we now use the safer default).
 166
 167  * The kinds of whitespace errors "git diff" and "git apply" notice (and
 168    fix) can be controlled via 'core.whitespace' configuration variable
 169    and 'whitespace' attribute in .gitattributes file.
 170
 171  * "git push" learned --dry-run option to show what would happen if a
 172    push is run.
 173
 174  * "git push" does not update a tracking ref on the local side when the
 175    remote refused to update the corresponding ref.
 176
 177  * "git push" learned --mirror option.  This is to push the local refs
 178    one-to-one to the remote, and deletes refs from the remote that do
 179    not exist anymore in the repository on the pushing side.
 180
 181  * "git push" can remove a corrupt ref at the remote site with the usual
 182    ":ref" refspec.
 183
 184  * "git remote" knows --mirror mode.  This is to set up configuration to
 185    push into a remote repository to store local branch heads to the same
 186    branch on the remote side, and remove branch heads locally removed
 187    from local repository at the same time.  Suitable for pushing into a
 188    back-up repository.
 189
 190  * "git remote" learned "rm" subcommand.
 191
 192  * "git cvsserver" can be run via "git shell".  Also, "cvs" is
 193    recognized as a synonym for "git cvsserver", so that CVS users
 194    can be switched to git just by changing their login shell.
 195
 196  * "git cvsserver" acts more like receive-pack by running post-receive
 197    and post-update hooks.
 198
 199  * "git am" and "git rebase" are far less verbose.
 200
 201  * "git pull" learned to pass --[no-]ff option to underlying "git
 202    merge".
 203
 204  * "git pull --rebase" is a different way to integrate what you fetched
 205    into your current branch.
 206
 207  * "git fast-export" produces datastream that can be fed to fast-import
 208    to reproduce the history recorded in a git repository.
 209
 210  * "git add -i" takes pathspecs to limit the set of files to work on.
 211
 212  * "git add -p" is a short-hand to go directly to the selective patch
 213    subcommand in the interactive command loop and to exit when done.
 214
 215  * "git add -i" UI has been colorized.
 216
 217  * "git commit --allow-empty" allows you to create a single-parent
 218    commit that records the same tree as its parent, overriding the usual
 219    safety valve.
 220
 221  * "git commit --amend" can amend a merge that does not change the tree
 222    from its first parent.
 223
 224  * "git commit" used to unconditionally strip comment lines that
 225    began with '#' and removed excess blank lines.  This
 226    behaviour has been made configurable.
 227
 228  * "git commit" has been rewritten in C.
 229
 230  * "git stash random-text" does not create a new stash anymore.  It was
 231    a UI mistake.  Use "git stash save random-text", or "git stash"
 232    (without extra args) for that.
 233
 234  * "git prune --expire <time>" can exempt young loose objects from
 235    getting pruned.
 236
 237  * "git branch --contains <commit>" can list branches that are
 238    descendants of a given commit.
 239
 240  * "git log" learned --early-output option to help interactive GUI
 241    implementations.
 242
 243  * "git bisect" learned "skip" action to mark untestable commits.
 244
 245  * "git bisect visualize" learned a shorter synonym "git bisect view".
 246
 247  * "git bisect visualize" runs "git log" in a non-windowed
 248    environments.  It also can be told what command to run (e.g. "git
 249    bisect visualize tig").
 250
 251  * "git format-patch" learned "format.numbered" configuration variable
 252    to automatically turn --numbered option on when more than one commits
 253    are formatted.
 254
 255  * "git ls-files" learned "--exclude-standard" to use the canned set of
 256    exclude files.
 257
 258  * "git tag -a -f existing" begins the editor session using the existing
 259    annotation message.
 260
 261  * "git tag -m one -m bar" (multiple -m options) behaves similarly to
 262    "git commit"; the parameters to -m options are formatted as separate
 263    paragraphs.
 264
 265  * The format "git show" outputs an annotated tag has been updated to
 266    include "Tagger: " and "Date: " lines from the tag itself.  Strictly
 267    speaking this is a backward incompatible change, but this is a
 268    reasonable usability fix and people's scripts shouldn't have been
 269    relying on the exact output from "git show" Porcelain anyway.
 270
 271  * "git cvsimport" did not notice errors from underlying "cvsps"
 272    and produced a corrupt import silently.
 273
 274  * "git cvsexportcommit" learned -w option to specify and switch to the
 275    CVS working directory.
 276
 277  * "git checkout" from a subdirectory learned to use "../path" to allow
 278    checking out a path outside the current directory without cd'ing up.
 279
 280  * "git checkout" from and to detached HEAD leaves a bit more
 281    information in the reflog.
 282
 283  * "git send-email --dry-run" shows full headers for easier diagnosis.
 284
 285  * "git merge-ours" is now built-in.
 286
 287  * "git svn" learned "info" and "show-externals" subcommands.
 288
 289  * "git svn" run from a subdirectory failed to read settings from the
 290    .git/config.
 291
 292  * "git svn" learned --use-log-author option, which picks up more
 293    descriptive name from From: and Signed-off-by: lines in the commit
 294    message.
 295
 296  * "git svn" wasted way too much disk to record revision mappings
 297    between svn and git; a new representation that is much more compact
 298    for this information has been introduced to correct this.
 299
 300  * "git svn" left temporary index files it used without cleaning them
 301    up; this was corrected.
 302
 303  * "git status" from a subdirectory now shows relative paths, which
 304    makes copy-and-pasting for git-checkout/git-add/git-rm easier.  The
 305    traditional behaviour to show the full path relative to the top of
 306    the work tree can be had by setting status.relativepaths
 307    configuration variable to false.
 308
 309  * "git blame" kept text for each annotated revision in core needlessly;
 310    this has been corrected.
 311
 312  * "git shortlog" learned to default to HEAD when the standard input is
 313    a terminal and the user did not give any revision parameter.
 314
 315  * "git shortlog" learned "-e" option to show e-mail addresses as well as
 316    authors' names.
 317
 318  * "git help" learned "-w" option to show documentation in browsers.
 319
 320  * In addition there are quite a few internal clean-ups. Notably
 321
 322    - many fork/exec have been replaced with run-command API,
 323      brought from the msysgit effort.
 324
 325    - introduction and more use of the option parser API.
 326
 327    - enhancement and more use of the strbuf API.
 328
 329
 330 Fixes since v1.5.3
 331 ------------------
 332
 333 All of the fixes in v1.5.3 maintenance series are included in
 334 this release, unless otherwise noted.
 335
 336 These fixes are only in v1.5.4 and not backported to v1.5.3 maintenance
 337 series.
 338
 339  * The way "git diff --check" behaves is much more consistent with the way
 340    "git apply --whitespace=warn" works.
 341
 342  * "git svn" talking with the SVN over http will correctly quote branch
 343    and project names.
 344
 345  * "git config" did not work correctly on platforms that define
 346    REG_NOMATCH to an even number.
