2 Overview
~~~~~~~~~~~

This is a maintenance release of memcached with a workaround for
common client issue as well as a few new stats.

3 Fixes
~~~~~~~~

3.1 Add partial backwards compatibility for delete with timeout 0.
===================================================================

Before version 1.4.0, there was an optional argument to delete that
would allow a client to specify that a deleted object should exist in
the cache after the deletion occurred such that add operations would
fail even though objects did not appear in the cache.

This feature was removed completely in 1.4.0, but a parser bug caused
it to slip through.  The bug was fixed in 1.4.3.  If anyone was
attempting to use it legitimately in the 1.4 series, it would simply
not work as expected.

The 1.4.4 backwards compatibility change allows specifically the value
of 0 (i.e. non-lingering delete), while continuing to reject others.
This will satisfy clients that always wish to send a value even when
they do not wish the item to linger.

4 New Features
