   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
  49Updates since v1.6.6
  50--------------------
  51
  52(subsystems)
  53
  54 * "git fast-import" updates; adds "option" and "feature" to detect the
  55   mismatch between fast-import and the frontends that produce the input
  56   stream.
  57
  58 * "git svn" support of subversion "merge tickets" and miscellaneous fixes.
  59
  60 * "gitk" updates.
  61
  62(portability)
  63
  64 * Some more MSVC portability patches for msysgit port.
  65
  66 * Minimum Pthreads emulation for msysgit port.
  67
  68(performance)
  69
  70 * More performance improvement patches for msysgit port.
  71
  72(usability, bells and whistles)
  73
  74 * More commands learned "--quiet" and "--[no-]progress" options.
  75
  76 * Various commands given by the end user (e.g. diff.type.textconv,
  77   and GIT_EDITOR) can be specified with command line arguments.  E.g. it
  78   is now possible to say "[diff "utf8doc"] textconv = nkf -w".
  79
  80 * "sparse checkout" feature allows only part of the work tree to be
  81   checked out.
  82
  83 * HTTP transfer can use authentication scheme other than basic
  84   (i.e./e.g. digest).
  85
  86 * Switching from a version of superproject that used to have a submodule
  87   to another version of superproject that no longer has it did not remove
  88   the submodule directory when it should (namely, when you are not
  89   interested in the submodule at all and didn't clone/checkout).
  90
  91 * A new attribute conflict-marker-size can be used to change the size of
  92   the conflict markers from the default 7; this is useful when tracked
  93   contents (e.g. git-merge documentation) have strings that resemble the
  94   conflict markers.
  95
  96 * A new syntax "<branch>@{upstream}" can be used on the command line to
  97   substitute the name of the "upstream" of the branch.  Missing branch
  98   defaults to the current branch, so "git fetch && git merge @{upstream}"
  99   will be equivalent to "git pull".
 100
 101 * "git branch --set-upstream" can be used to update the (surprise!) upstream
 102   i.e. where the branch is supposed to pull and merge from (or rebase onto).
 103
 104 * "git checkout A...B" is a way to detach HEAD at the merge base between
 105   A and B.
 106
 107 * "git checkout -m path" to reset the work tree file back into the
 108   conflicted state works even when you already ran "git add path" and
 109   resolved the conflicts.
 110
 111 * "git commit --date='<date>'" can be used to override the author date
 112   just like "git commit --author='<name> <email>'" can be used to
 113   override the author identity.
 114
 115 * "git commit --no-status" can be used to omit the listing of the index
 116   and the work tree status in the editor used to prepare the log message.
 117
 118 * "git commit" warns a bit more aggressively until you configure user.email,
 119   whose default value almost always is not (and fundamentally cannot be)
 120   what you want.
 121
 122 * "git difftool" has been extended to make it easier to integrate it
 123   with gitk.
 124
 125 * "git fetch --all" can now be used in place of "git remote update".
 126
 127 * "git grep" does not rely on external grep anymore.  It can use more than
 128   one threads to accelerate the operation.
 129
 130 * "git grep" learned "--no-index" option, to search inside contents that
 131   are not managed by git.
 132
 133 * "git grep" learned "--quiet" option.
 134
 135 * "git log" and friends learned "--glob=heads/*" syntax that is a more
 136   flexible way to complement "--branches/--tags/--remotes".
 137
 138 * "git merge" learned to pass options specific to strategy-backends.  E.g.
 139
 140    - "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
 141      strategy how much to shift the trees explicitly.
 142
 143    - "git merge -Xtheirs" can be used to auto-merge as much as possible,
 144      while discarding your own changes and taking merged version in
 145      conflicted regions.
 146
 147 * "git push" learned "git push origin --delete branch", a syntactic sugar
 148   for "git push origin :branch".
 149
 150 * "git push" learned "git push --set-upstream origin forker:forkee" that
 151   lets you configure your "forker" branch to later pull from "forkee"
 152   branch at "origin".
 153
 154 * "git rebase --onto A...B" means the history is replayed on top of the
 155   merge base between A and B.
 156
 157 * "git rebase -i" learned new action "fixup", that squashes the change
 158   but does not affect existing log message.
 159
 160 * "git rebase -i" also learned --autosquash option, that is useful
 161   together with the new "fixup" action.
 162
 163 * "git remote" learned set-url subcommand, to update (surprise!) url
 164   for an existing remote nickname.
 165
 166 * "git rerere" learned "forget path" subcommand.  Together with "git
 167   checkout -m path" it will be useful when you recorded a wrong
 168   resolution.
 169
 170 * Use of "git reset --merge" has become easier when resetting away a
 171   conflicted mess left in the work tree.
 172
 173 * "git rerere" had rerere.autoupdate configuration but there was no way
 174   to countermand it from the command line; --no-rerere-autoupdate option
 175   given to "merge", "revert", etc. fixes this.
 176
 177 * "git status" learned "-s(hort)" output format.
 178
 179(developers)
 180
 181 * The infrastructure to build foreign SCM interface has been updated.
 182
 183 * Many more commands are now built-in.
 184
 185 * THREADED_DELTA_SEARCH is no more.  If you build with threads, delta
 186   compression will always take advantage of it.
 187
 188Fixes since v1.6.6
 189------------------
 190
 191All of the fixes in v1.6.6.X maintenance series are included in this
 192release, unless otherwise noted.
 193
 194 * "git branch -d branch" used to refuse deleting the branch even when
 195   the branch is fully merged to its upstream branch if it is not merged
 196   to the current branch.  It now deletes it in such a case.
 197
 198 * "git config -f <relative path>" run from a subdirectory misbehaved.
 199   65807ee (builtin-config: Fix crash when using "-f <relative path>"
 200   from non-root dir, 2010-01-26) may be merged to older maintenance
 201   branches.
 202
 203 * When "git diff" is asked to compare the work tree with something,
 204   it used to consider that a checked-out submodule with uncommitted
 205   changes is not modified; this could cause people to forget committing
 206   these changes in the submodule before committing in the superproject.
 207   It now considers such a change as a modification.
