What's in git.git

* The 'maint' branch has these fixes since the last announcement.

 - Documentation cleanups (Sean Estabrooks)
 - git-format-patch uses rfc2822 compliant date (Huw Davies).
 - git-am usability fixes (Robert Shearman and me)
 - Fix filename verification when in a subdirectory (Linus)
 - git-send-email debuggability improvements (Martin Langhoff)
 - annotate fixes (Matthias Kestenholz)
 - rebase: typofix.
 - commit-tree.c: check_valid() microoptimization.
 - verify-pack: check integrity in a saner order.


* The 'master' branch has these since the last announcement, in
  addition to the above fixes.

 - gitk views and highlights enhancements (Paul Mackerras).
 - repo-config -l (Petr Baudis and Johannes Schindelin)
 - repo-config white-space fix (Johannes Schindelin)
 - diff --stat fix.
 - revision parsing more strictly checks "rev -- paths"
 - t0000-basic: more commit-tree tests.
 - Extended SHA1 -- "rev^@" syntax to mean "all parents"
 - Fix "git help -a" terminal autosizing (Linus)
 - git-fetch: resolve remote symrefs for HTTP transport (Nick Hengeveld)
 - daemon: socksetup: don't return on set_reuse_addr() error (Serge E. Hallyn)


* The 'next' branch, in addition, has these.

 - built-in git-count-objects
 - built-in git-diff.
 - built-in git-push (Linus with fix by Johannes Schindelin).
 - built-in git-log.
 - built-in git-grep.

   These not only implement them built-in, but remove the
   corresponding shell script versions.  I think all of them are
   ready to be pushed out, so expect them soon in your "master"
   branch ;-).

 - repo-config: support --get-regexp (Johannes Schindelin)
 - core.prefersymlinkrefs: use symlinks for .git/HEAD
 - get_sha1(): :path and :[0-3]:path to extract from index.
 
  Needs a bit more testing.

 - further diff-delta improvements (Nicolas Pitre)

   Benchmark impressions are welcome on this.  

 - cache-tree optimization

   This yields a nice speedup to (apply then write-tree)+
   sequence, but is rather intrusive and risky (if somebody
   forgets to invalidate a cached information the next write
   tree can write out corrupt data).  I am hoping we can redo
   this inside the index.

 - built-in git-fmt-patch

   This is not ready as format-patch replacement yet; it only
   does --stdout.

* The 'pu' branch, in addition, has these.

 - read-tree: --prefix=<path> option.
 - write-tree: --exclude=<prefix>
 - write-tree: --prefix=<path>
      
   These were originally done as part of "bind commit" series,
   but are useful outside the context of subproject support.
   read-tree --prefix=<path> allows you to graft a tree object
   at a subdirectory in an already populated index, and
   write-tree --prefix=<path> allows you to write out only a
   subdirectory out of an index as a tree object.  I am not in
   an urgent need for these features, but if some Porcelain
   finds them useful, they can be merged to "next".
