Git v1.7.0 Release Notes

========================

Notes on behaviour change

-------------------------

* "git push" into a branch that is currently checked out (i.e. pointed by

HEAD in a repository that is not bare) is refused by default.

Similarly, "git push $there :$killed" to delete the branch $killed

in a remote repository $there, when $killed branch is the current

branch pointed at by its HEAD, will be refused by default.

Setting the configuration variables receive.denyCurrentBranch and

receive.denyDeleteCurrent to 'ignore' in the receiving repository

can be used to override these safety features.

* "git send-email" does not make deep threads by default when sending a

patch series with more than two messages. All messages will be sent

as a reply to the first message, i.e. cover letter.

It has been possible to configure send-email to send "shallow thread"

by setting sendemail.chainreplyto configuration variable to false. The

only thing this release does is to change the default when you haven't

configured that variable.

* "git status" is not "git commit --dry-run" anymore. This change does

not affect you if you run the command without pathspec.

* "git diff" traditionally treated various "ignore whitespace" options

only as a way to filter the patch output. "git diff --exit-code -b"

exited with non-zero status even if all changes were about changing the

ammount of whitespace and nothing else. and "git diff -b" showed the

"diff --git" header line for such a change without patch text.

In this release, the "ignore whitespaces" options affect the semantics

of the diff operation. A change that does not affect anything but

whitespaces is reported with zero exit status when run with

--exit-code, and there is no "diff --git" header for such a change.
