* Command tokenizer performance and cleanliness improvement.
  Patch contributed by Paolo Borelli <paolo.borelli@gmail.com>.

* Add notes to README about MacOS, libevent and kqueue.

* Windows Patch integration -- part 1, warnings elimination.

* Allow changes to the verbosity level of the server with a new
  "verbosity" command and some compiler cleanups.
  Patch contributed by Paolo Borelli <paolo.borelli@gmail.com>.

* Add cleanup patch from "Tim Yardley" <liquid@haveheart.com> to
  clean up source spacing issues, fix -Wall warnings, add some
  null checks, adds asserts at the top of each function for any
  use of conn *c without checking to see if c is NULL first.

* Also adjust clean-whitespace.pl to clean *.ac files.  Add
  script to test-suite to test for tabs.

* Add clarification of flush_all in the protocol docs
  from Elizabeth Mattijsen <liz@dijkmat.nl>

* Add patch from Eli Bingham <eli@pandora.com> to
  re-enable the -n switch to memcached.

* Add patch to collect eviction statistics from
  Jean-Francois BUSTARRET <jfbustarret@wat.tv>.

* Updated docs, added new test cases for t/stats.t

* Add more test cases using larger buffer sizes up to and greater
  than 1MB.

* Remove unused parameter to item_size_ok()

* Use a single printf() in usage()

* Add a failing test for conforming with maximum connections.

* crash fix from Thomas van Gulick <thomas@partyflock.nl> in
  conn_shrink(), passing &ptr, instead of ptr to realloc().

* Fix a number of places where (s)printf calls were using unsigned
  or signed formats that did not match their arguments.

* Add support for stdbool.h and stdint.h to use the bool and
  uint8_t types.

* Major refactoring - move API calls for assoc/items/slabs to
  their own individual header files.  Add apropriate const and
  static declarations as appropriate.

* Avoid type-punning.  Do a more efficient realloc inside the
  conn_shrink routine.

* Fix overflow bug where uninitialized access to slabclass caused
  size-0 mallocs during slab preallocation.

* Use EXIT_SUCCESS/EXIT_FAILURE constants.

* Convert some sprintf calls to snprintf to protect against
  buffer overflows.

* Explicitly compare against NULL or zero in many places.

* Steven Grimm <sgrimm@facebook.com>: Per-object-type stats collection
  support. Specify the object type delimiter with the -D command line
  option. Turn stats gathering on and off with "stats detail on" and
  "stats detail off". Dump the per-object-type details with
  "stats detail dump".

* Steven Grimm <sgrimm@facebook.com>: Fix an off-by-one error in the
  multithreaded version's message passing code.

* fix expirations of items set with absolute expiration times in
  the past, before the server's start time.  bug was introduced in
  1.2.0 with rel_time_t.  Thanks to Adam Dixon
  <adamtdixon@gmail.com> for the bug report and test case!

* Steven Grimm <sgrimm@facebook.com>: Performance improvements:

* Steve Peters <steve@fisharerojo.org>: OpenBSD has a malloc.h,
  but warns to use stdlib.h instead

* Steven Grimm <sgrimm@facebook.com>: Add support for multithreaded
  execution. Run configure with "--enable-threads" to enable. See
  doc/threads.txt for details.

* Iain Wade <iwade@optusnet.com.au>: Fix for UDP responses on non-"get"
  commands.

* Steven Grimm <sgrimm@facebook.com>: Dynamic sizing of hashtable to
  reduce collisions on very large caches and conserve memory on
  small caches.

* Steven Grimm <sgrimm@facebook.com>: New faster hash function.
