++0.38
++
++ * memcached_purge() now calls any callbacks registered during get
++   execution.
++
 +0.37 Mon Jan 11 16:29:57 PST 2010
 + * Fixed build for libhashkit.
 + * Fixed install path regression.  
 + * Modified RPM to strict check install. 
 + * Added documentation for memcached_server_cursor();
 + * Added memcached_servers_reset().
 + * Modified memcached_st to remove dead cursor_server member.
 +
 +0.36 Wed Jan  6 18:23:50 PST 2010
 +  * Merged in new memslap utility.
 +  * All of constants.h has been updated to match style (all old identifiers
 +    continue to work).
 +  * Added first pass for libhashkit.
 +  * Updated test Framework/extended tests.
 +  * Random read support during replication added.
 +  * Modified use_sort so that the option can be applied to any distribution type.
 +  * We removed the MEMCACHED_BEHAVIOR_KETAMA_COMPAT_MODE added in 0.35. Instead use
 +    memcached_behavior_set_distribution().
 +
  0.35 Mon Nov  9 11:18:33 PST 2009
    * Added support for by_key operations for inc/dec methods.
