GIT v1.6.6 Release Notes
========================

In this release, "git fsck" defaults to "git fsck --full" and checks
packfiles, and because of this it will take much longer to complete
than before.  If you prefer a quicker check only on loose objects (the
old default), you can say "git fsck --no-full".  This has been
supported by 1.5.4 and newer versions of git, so it is safe to write
it in your script even if you use slightly older git on some of your
machines.

In git 1.7.0, which is planned to be the release after 1.6.6, "git
push" into a branch that is currently checked out will be refused by
default.

You can choose what should happen upon such a push by setting the
configuration variable receive.denyCurrentBranch in the receiving
repository.

Also, "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.

You can choose what should happen upon such a push by setting the
configuration variable receive.denyDeleteCurrent in the receiving
repository.

To ease the transition plan, the receiving repository of such a
push running this release will issue a big warning when the
configuration variable is missing.  Please refer to:

for more details on the reason why this change is needed and the
transition plan.

Updates since v1.6.5
--------------------

(subsystems)

(portability)

(performance)

(usability, bells and whistles)

 * The object replace mechanism can be bypassed with --no-replace-objects
   global option given to the "git" program.

 * "git fsck" by default checks the packfiles (i.e. "--full" is the
   default); you can turn it off with "git fsck --no-full".

 * import-tars contributed fast-import frontend learned more types of
   compressed tarballs.

 * "git instaweb" knows how to talk with mod_cgid to apache2.

 * "git log --decorate" shows the location of HEAD as well.

 * "git rebase -i" learned "reword" that acts like "edit" but immediately
   starts an editor to tweak the log message without returning control to
   the shell, which is done by "edit" to give an opportunity to tweak the
   contents.

 * Author names shown in gitweb output are links to search commits by the
   author.

Fixes since v1.6.5
------------------

All of the fixes in v1.6.5.X maintenance series are included in this
release, unless otherwise noted.

 * "git apply" and "git diff" (including patch output from "git log -p")
   now flags trailing blank lines as whitespace errors correctly (only
   "apply --whitespace=fix" stripped them but "apply --whitespace=warn"
   did not even warn).

 * Two whitespace error classes, 'blank-at-eof' and 'blank-at-eol', have
   been introduced (settable by core.whitespace configuration variable and
   whitespace attribute).  The 'trailing-space' whitespace error class has
   become a short-hand to cover both of these and there is no behaviour
   change for existing set-ups.

 * "git cvsimport" did not work well when it is fed filenames from the
   command line and is not started at the top of the work tree.  We should
   backport this by merging f6fdbb6 (cvsimport: fix relative argument
   filenames, 2009-10-19).

 * The way gitweb escapes its CGI parameters were broken especially when
   the parameter was a UTF-8 string.  We may want to backport this to
   1.6.5.X series by merging 452e225 (gitweb: fix esc_param, 2009-10-13).

 * gitweb used to show 'patch' link for merge commits but the output from
   it is not usable to feed "git am" with.  We may want to backport this
   to 1.6.5.X series by merging 1655c98 (gitweb: Do not show 'patch' link
   for merge commits, 2009-10-09).
