   1Git v1.7.0 Release Notes
   2========================
   3
   4Notes on behaviour change
   5-------------------------
   6
   7 * "git push" into a branch that is currently checked out (i.e. pointed by
   8   HEAD in a repository that is not bare) is refused by default.
   9
  10   Similarly, "git push $there :$killed" to delete the branch $killed
  11   in a remote repository $there, when $killed branch is the current
  12   branch pointed at by its HEAD, will be refused by default.
  13
  14   Setting the configuration variables receive.denyCurrentBranch and
  15   receive.denyDeleteCurrent to 'ignore' in the receiving repository
  16   can be used to override these safety features.
  17
  18 * "git send-email" does not make deep threads by default when sending a
  19   patch series with more than two messages.  All messages will be sent
  20   as a reply to the first message, i.e. cover letter.
  21
  22   It has been possible to configure send-email to send "shallow thread"
  23   by setting sendemail.chainreplyto configuration variable to false.  The
  24   only thing this release does is to change the default when you haven't
  25   configured that variable.
  26
  27 * "git status" is not "git commit --dry-run" anymore.  This change does
  28   not affect you if you run the command without argument.
  29
  30 * "git diff" traditionally treated various "ignore whitespace" options
  31   only as a way to filter the patch output.  "git diff --exit-code -b"
  32   exited with non-zero status even if all changes were about changing the
  33   ammount of whitespace and nothing else.  and "git diff -b" showed the
  34   "diff --git" header line for such a change without patch text.
  35
  36   In this release, the "ignore whitespaces" options affect the semantics
  37   of the diff operation.  A change that does not affect anything but
  38   whitespaces is reported with zero exit status when run with
  39   --exit-code, and there is no "diff --git" header for such a change.
  40
  41 * External diff and textconv helpers are now executed using the shell.
  42   This makes them consistent with other programs executed by git, and
  43   allows you to pass command-line parameters to the helpers. Any helper
  44   paths containing spaces or other metacharacters now need to be
  45   shell-quoted.  The affected helpers are GIT_EXTERNAL_DIFF in the
  46   environment, and diff.*.command and diff.*.textconv in the config
  47   file.
  48
  49 * The --max-pack-size argument to 'git repack' and 'git pack-objects' was
  50   assuming the provided size to be expressed in MiB, unlike the
  51   corresponding config variable and other similar options accepting a size
  52   value.  It is now expecting a size expressed in bytes, with a possible
  53   unit suffix of 'k', 'm', or 'g'.
  54
  55Updates since v1.6.6
  56--------------------
  57
  58(subsystems)
  59
  60 * "git fast-import" updates; adds "option" and "feature" to detect the
  61   mismatch between fast-import and the frontends that produce the input
  62   stream.
  63
  64 * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
  65
  66 * "gitk" updates.
  67
  68(portability)
  69
  70 * Some more MSVC portability patches for msysgit port.
  71
  72 * Minimum Pthreads emulation for msysgit port.
  73
  74(performance)
  75
  76 * More performance improvement patches for msysgit port.
  77
  78(usability, bells and whistles)
  79
  80 * More commands learned "--quiet" and "--[no-]progress" options.
  81
  82 * Various commands given by the end user (e.g. diff.type.textconv,
  83   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
  84   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
  85
  86 * "sparse checkout" feature allows only part of the work tree to be
  87   checked out.
  88
  89 * HTTP transfer can use authentication scheme other than basic
  90   (i.e./e.g. digest).
  91
  92 * Switching from a version of superproject that used to have a submodule
  93   to another version of superproject that no longer has it did not remove
  94   the submodule directory when it should (namely, when you are not
  95   interested in the submodule at all and didn't clone/checkout).
  96
  97 * A new attribute conflict-marker-size can be used to change the size of
  98   the conflict markers from the default 7; this is useful when tracked
  99   contents (e.g. git-merge documentation) have strings that resemble the
 100   conflict markers.
 101
 102 * A new syntax "<branch>@{upstream}" can be used on the command line to
 103   substitute the name of the "upstream" of the branch.  Missing branch
 104   defaults to the current branch, so "git fetch && git merge @{upstream}"
 105   will be equivalent to "git pull".
 106
 107 * "git branch --set-upstream" can be used to update the (surprise!) upstream
 108   i.e. where the branch is supposed to pull and merge from (or rebase onto).
 109
 110 * "git checkout A...B" is a way to detach HEAD at the merge base between
 111   A and B.
 112
 113 * "git checkout -m path" to reset the work tree file back into the
 114   conflicted state works even when you already ran "git add path" and
 115   resolved the conflicts.
 116
 117 * "git commit --date='<date>'" can be used to override the author date
 118   just like "git commit --author='<name> <email>'" can be used to
 119   override the author identity.
 120
 121 * "git commit --no-status" can be used to omit the listing of the index
 122   and the work tree status in the editor used to prepare the log message.
 123
 124 * "git commit" warns a bit more aggressively until you configure user.email,
 125   whose default value almost always is not (and fundamentally cannot be)
 126   what you want.
 127
 128 * "git difftool" has been extended to make it easier to integrate it
 129   with gitk.
 130
 131 * "git fetch --all" can now be used in place of "git remote update".
 132
 133 * "git grep" does not rely on external grep anymore.  It can use more than
 134   one threads to accelerate the operation.
 135
 136 * "git grep" learned "--no-index" option, to search inside contents that
 137   are not managed by git.
 138
 139 * "git grep" learned "--quiet" option.
 140
 141 * "git log" and friends learned "--glob=heads/*" syntax that is a more
 142   flexible way to complement "--branches/--tags/--remotes".
 143
 144 * "git merge" learned to pass options specific to strategy-backends.  E.g.
 145
 146    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
 147      strategy how much to shift the trees explicitly.
 148
 149    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
 150      while discarding your own changes and taking merged version in
 151      conflicted regions.
 152
 153 * "git push" learned "git push origin --delete branch", a syntactic sugar
 154   for "git push origin :branch".
 155
 156 * "git push" learned "git push --set-upstream origin forker:forkee" that
 157   lets you configure your "forker" branch to later pull from "forkee"
 158   branch at "origin".
 159
 160 * "git rebase --onto A...B" means the history is replayed on top of the
 161   merge base between A and B.
 162
 163 * "git rebase -i" learned new action "fixup", that squashes the change
 164   but does not affect existing log message.
 165
 166 * "git rebase -i" also learned --autosquash option, that is useful
 167   together with the new "fixup" action.
 168
 169 * "git remote" learned set-url subcommand, to update (surprise!) url
 170   for an existing remote nickname.
 171
 172 * "git rerere" learned "forget path" subcommand.  Together with "git
 173   checkout -m path" it will be useful when you recorded a wrong
 174   resolution.
 175
 176 * Use of "git reset --merge" has become easier when resetting away a
 177   conflicted mess left in the work tree.
 178
 179 * "git rerere" had rerere.autoupdate configuration but there was no way
 180   to countermand it from the command line; --no-rerere-autoupdate option
 181   given to "merge", "revert", etc. fixes this.
 182
 183 * "git status" learned "-s(hort)" output format.
 184
 185(developers)
 186
 187 * The infrastructure to build foreign SCM interface has been updated.
 188
 189 * Many more commands are now built-in.
 190
 191 * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
 192   compression will always take advantage of it.
 193
 194Fixes since v1.6.6
 195------------------
 196
 197All of the fixes in v1.6.6.X maintenance series are included in this
 198release, unless otherwise noted.
 199
 200 * "git branch -d branch" used to refuse deleting the branch even when
 201   the branch is fully merged to its upstream branch if it is not merged
 202   to the current branch.  It now deletes it in such a case.
 203
 204 * "git config -f <relative path>" run from a subdirectory misbehaved.
 205   65807ee (builtin-config: Fix crash when using "-f <relative path>"
 206   from non-root dir, 2010-01-26) may be merged to older maintenance
 207   branches.
 208
 209 * When using "git status" or asking "git diff" to compare the work tree
 210   with something, they used to consider that a checked-out submodule with
 211   uncommitted changes is not modified; this could cause people to forget
 212   committing these changes in the submodule before committing in the
 213   superproject. They now consider such a change as a modification and
 214   "git diff" will append a "-dirty" to the work tree side when generating
 215   patch output or when used with the --submodule option.
