GIT v1.6.5 Release Notes
========================

In git 1.7.0, which was planned to be the release after 1.6.5, "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 v1.6.4
--------------------

(subsystems)

 * various updates to gitk, git-svn and gitweb.

(portability)

 * more improvements on mingw port.

 * mingw will also give FRSX as the default value for the LESS
   environment variable when the user does not have one.

 * initial support to compile git on Windows with MSVC.

(performance)

 * On major platforms, the system can be compiled to use with Linus's
   block-sha1 implementation of the SHA-1 hash algorithm, which
   outperforms the default fallback implementation we borrowed from
   Mozilla.

 * Unnecessary inefficiency in deepening of a shallow repository has
   been removed.

 * "git clone" does not grab objects that it does not need (i.e.
   referenced only from refs outside refs/heads and refs/tags
   hierarchy) anymore.

 * The "git" main binary used to link with libcurl, which then dragged
   in a large number of external libraries.  When using basic plumbing
   commands in scripts, this unnecessarily slowed things down.  We now
   implement http/https/ftp transfer as a separate executable as we
   used to.

 * "git clone" run locally hardlinks or copies the files in .git/ to
   newly created repository.  It used to give new mtime to copied files,
   but this delayed garbage collection to trigger unnecessarily in the
   cloned repository.  We now preserve mtime for these files to avoid
   this issue.

(usability, bells and whistles)

 * Human writable date format to various options, e.g. --since=yesterday,
   master@{2000.09.17}, are taught to infer some omitted input properly.

 * A few programs gave verbose "advice" messages to help uninitiated
   people when issuing error messages.  An infrastructure to allow
   users to squelch them has been introduced, and a few such messages
   can be silenced now.

 * refs/replace/ hierarchy is designed to be usable as a replacement
   of the "grafts" mechanism, with the added advantage that it can be
   transferred across repositories.

 * "git am" learned to optionally ignore whitespace differences.

 * "git am" handles
