GIT v1.6.4 Release Notes
========================

With the next major release, "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.

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.

For a similar reason, "git push $there :$killed" to delete the branch
$killed in a remote repository $there, if $killed branch is the current
branch pointed at by its HEAD, gets a large warning.  You can choose what
should happen upon such a push by setting the configuration variable
receive.denyDeleteCurrent in the receiving repository.


Updates since v1.6.3
--------------------

(subsystems)

 * gitweb Perl style clean-up.

 * git-svn updates, including a new --authors-prog option to map author
   names by invoking an external program, 'git svn reset' to unwind
   'git svn fetch', support for more than one branches, documenting
   of the useful --minimize-url feature, new "git svn gc" command, etc.

(portability)

 * We feed iconv with "UTF-8" instead of "utf8"; the former is
   understood more widely.  Similarly updated test scripts to use
   encoding names more widely understood (e.g. use "ISO8859-1" instead
   of "ISO-8859-1").

 * Various portability fixes/workarounds for different vintages of
   SunOS, IRIX, and Windows.

 * Git-over-ssh transport on Windows supports PuTTY plink and TortoisePlink.

(performance)

 * Many repeated use of lstat() are optimized out in "checkout" codepath.

 * git-status (and underlying git-diff-index --cached) are optimized
   to take advantage of cache-tree information in the index.

(usability, bells and whistles)

 * "git add --edit" lets users edit the whole patch text to fine-tune what
   is added to the index.

 * "git am" accepts StGIT series file as its input.

 * "git bisect skip" skips to a more randomly chosen place in the hope
   to avoid testing a commit that is too close to a commit that is
   already known to be untestable.

 * "git cvsexportcommit" learned -k option to stop CVS keywords expansion

 * "git fast-export" learned to handle history simplification more
   gracefully.

 * "git fast-export" learned an option --tag-of-filtered-object to handle
   dangling tags resulting from
