1Git v1.7.0 Release Notes
2========================
34
Notes on behaviour change
5-------------------------
67
* "git push" into a branch that is currently checked out (i.e. pointed by
8HEAD in a repository that is not bare) is refused by default.
910
Similarly, "git push $there :$killed" to delete the branch $killed
11in a remote repository $there, when $killed branch is the current
12branch pointed at by its HEAD, will be refused by default.
1314
Setting the configuration variables receive.denyCurrentBranch and
15receive.denyDeleteCurrent to 'ignore' in the receiving repository
16can be used to override these safety features.
1718
* "git send-email" does not make deep threads by default when sending a
19patch series with more than two messages. All messages will be sent
20as a reply to the first message, i.e. cover letter.
2122
It has been possible to configure send-email to send "shallow thread"
23by setting sendemail.chainreplyto configuration variable to false. The
24only thing this release does is to change the default when you haven't
25configured that variable.
2627
* "git status" is not "git commit --dry-run" anymore. This change does
28not affect you if you run the command without pathspec.
2930
* "git diff" traditionally treated various "ignore whitespace" options
31only as a way to filter the patch output. "git diff --exit-code -b"
32exited with non-zero status even if all changes were about changing the
33ammount of whitespace and nothing else. and "git diff -b" showed the
34"diff --git" header line for such a change without patch text.
3536
In this release, the "ignore whitespaces" options affect the semantics
37of the diff operation. A change that does not affect anything but
38whitespaces is reported with zero exit status when run with
39--exit-code, and there is no "diff --git" header for such a change.
4041
* external diff and textconv helpers are now executed using the shell.
42This makes them consistent with other programs executed by git, and
43allows you to pass command-line parameters to the helpers. Any helper
44paths containing spaces or other metacharacters now need to be
45shell-quoted. The affected helpers are GIT_EXTERNAL_DIFF in the
46environment, and diff.*.command and diff.*.textconv in the config
47file.

Updates since v1.6.6
50--------------------
5152
(subsystems)
5354
* "git fast-import" updates; adds "option" and "feature" to detect the
55mismatch between fast-import and the frontends that produce the input
56stream.
5758
* "git svn" support of subversion "merge tickets" and miscellaneous fixes.
5960
* "gitk" updates.
6162
(portability)
6364
* Some more MSVC portability patches for msysgit port.
6566
* Minimum Pthreads emulation for msysgit port.
6768
(performance)
6970
* More performance improvement patches for msysgit port.
7172
(usability, bells and whistles)
7374
* More commands learned "--quiet" and "--[no-]progress" options.
7576
* Various commands given by the end user (e.g. diff.type.textconv,
77and GIT_EDITOR) can be specified with command line arguments. E.g. it
78is now possible to say "[diff "utf8doc"] textconv = nkf -w".
7980
* "sparse checkout" feature allows only part of the work tree to be
81checked out.
8283
* HTTP transfer can use authentication scheme other than basic
84(i.e./e.g. digest).
8586
* Switching from a version of superproject that used to have a submodule
87to another version of superproject that no longer has it did not remove
88the submodule directory when it should (namely, when you are not
89interested in the submodule at all and didn't clone/checkout).
9091
* A new attribute conflict-marker-size can be used to change the size of
92the conflict markers from the default 7; this is useful when tracked
93contents (e.g. git-merge documentation) have strings that resemble the
94conflict markers.
9596
* A new syntax "<branch>@{upstream}" can be used on the command line to
97substitute the name of the "upstream" of the branch. Missing branch
98defaults to the current branch, so "git fetch && git merge @{upstream}"
99will be equivalent to "git pull".
100101
* "git branch --set-upstream" can be used to update the (surprise!) upstream
102i.e. where the branch is supposed to pull and merge from (or rebase onto).
103104
* "git checkout A...B" is a way to detach HEAD at the merge base between
105A and B.
106107
* "git checkout -m path" to reset the work tree file back into the
108conflicted state works even when you already ran "git add path" and
109resolved the conflicts.
110111
* "git commit --date='<date>'" can be used to override the author date
112just like "git commit --author='<name> <email>'" can be used to
113override the author identity.
114115
* "git commit --no-status" can be used to omit the listing of the index
116and the work tree status in the editor used to prepare the log message.
117118
* "git commit" warns a bit more aggressively until you configure user.email,
119whose default value almost always is not (and fundamentally cannot be)
120what you want.
121122
* "git difftool" has been extended to make it easier to integrate it
123with gitk.
124125
* "git fetch --all" can now be used in place of "git remote update".
126127
* "git grep" does not rely on external grep anymore. It can use more than
128one threads to accelerate the operation.
129130
* "git grep" learned "--no-index" option, to search inside contents that
131are not managed by git.
132133
* "git grep" learned "--quiet" option.
134135
* "git log" and friends learned "--glob=heads/*" syntax that is a more
136flexible way to complement "--branches/--tags/--remotes".
137138
* "git merge" learned to pass options specific to strategy-backends. E.g.
139140
- "git merge -Xsubtree=path/to/directory" can be used to tell the subtree
141strategy how much to shift the trees explicitly.
142143
- "git merge -Xtheirs" can be used to auto-merge as much as possible,
144while discarding your own changes and taking merged version in
145conflicted regions.
146147
* "git push" learned "git push origin --delete branch", a syntactic sugar
148for "git push origin :branch".
149150
* "git push" learned "git push --set-upstream origin forker:forkee" that
151lets you configure your "forker" branch to later pull from "forkee"
152branch at "origin".
153154
* "git rebase --onto A...B" means the history is replayed on top of the
155merge base between A and B.
156157
* "git rebase -i" learned new action "fixup", that squashes the change
158but does not affect existing log message.
159160
* "git rebase -i" also learned --autosquash option, that is useful
161together with the new "fixup" action.
162163
* "git remote" learned set-url subcommand, to update (surprise!) url
164for an existing remote nickname.
165166
* "git rerere" learned "forget path" subcommand. Together with "git
167checkout -m path" it will be useful when you recorded a wrong
168resolution.
169170
* Use of "git reset --merge" has become easier when resetting away a
171conflicted mess left in the work tree.
172173
* "git rerere" had rerere.autoupdate configuration but there was no way
174to countermand it from the command line; --no-rerere-autoupdate option
175given to "merge", "revert", etc. fixes this.
176177
* "git status" learned "-s(hort)" output format.
178179
(developers)
180181
* The infrastructure to build foreign SCM interface has been updated.
182183
* Many more commands are now built-in.

Fixes since v1.6.6
186------------------
187188
All of the fixes in v1.6.6.X maintenance series are included in this
189release, unless otherwise noted.
190191
* "git branch -d branch" used to refuse deleting the branch even when
192the branch is fully merged to its upstream branch if it is not merged
193to the current branch. It now deletes it in such a case.
194195
* "git config -f <relative path>" run from a subdirectory misbehaved.
19665807ee (builtin-config: Fix crash when using "-f <relative path>"
197from non-root dir, 2010-01-26) may be merged to older maintenance
198branches.
199200
* When "git diff" is asked to compare the work tree with something,
201it used to consider that a checked-out submodule with uncommitted
202changes is not modified; this could cause people to forget committing
203these changes in the submodule before committing in the superproject.
204It now considers such a change as a modification.
