	-- released as version 0.9.8
	-- added flushAll method, which allows invalidating the entire cache on
		all servers (or subset). (whalin)

		(or subset).  Data is pulled back in data structure for end user to

	-- changed failver code to rehash in a better manner (more efficient when
		a server dies) (russo)
	-- add optional custom hashing method, which should be compatable with
		other memcached clients (perl/php/python, etc), but will be slower
		Java's built in hashCode for String (due to String pooling). (whalin,
		russo)
	-- fixed Java to actually return modulus (instead of remainder) when
		selecting a bucket (russo)
	-- fixed a typo in the getNagle method (whalin)

26 May 2004
	-- released as version 0.9.6
	-- Fixed bug where reading from socket when server dies will cause tight
		loop.  Also cleaned up error handling to throw exceptions in more
		failed situations. (whalin)

25 May 2004
	-- released as version 0.9.5
	-- Heavy cleanup of client code to better deal with error conditions, use
		java naming conventions, and remove some of the overloaded convenience
		methods.  Also changed how client deals with pulling objects from
		cache when not serialized to be more type safe.
	-- Created connection pool to manage connections to various caching servers
		maintaining persistent connections.
	-- Changed SockIO to be internal static class to the pool.
	-- Added support for more socket options (nagle, timeout).
	-- Removed deprecated stream operations.
	-- Heavyily javadoc'd
	-- Added in useage of log4j (could use J2SE logger as well)
	-- NOTE: Not backwards compatible with earlier versions!!!

12 Oct 2003
	-- released as version 0.9.1
	-- Altered the SockIO helper class, so it no longer allows accessing
		the streams it contains directly, instead it has methods
		with identical signatures to the methods that were called
		on the streams... This makes the client code prettier.
	-- Changed looped non blocking read to blocking read, for getting
		items from the server. This probably reduces CPU usage in
		cases where the retrieval would block, and cleans up the
		code a bit.  We're blocking on retrieval anyhow.
	-- Made get() not call get_multi(), and added single socket
		optimization. This parallels recent changes to the perl
		client
	-- Changed a few for loops to use iterators instead, since it's
		probably marginally more efficient, and it's probably
		better coding practice.
	-- Actually spell checked. :)

29 Sep 2003
	-- released as version 0.9.0
	-- Renumbered to reflect that it's not been realworld tested
	-- changed package to danga.com.MemCached (thanks)
	-- added dates to changelog
	-- added .txt to text files
	-- added to official memcached site :)

28 Sep 2003
	-- released as version 1.0
	-- Adjusted namespacing for SockIO, it shouldn't have been public; is now package level.
		As a bonus, this means I don't have to Javadoc it. :)
	-- Finished adding complete Javadoc to MemCachedClient.
	-- spellchecked
	-- added a couple versions of function variations that I missed. for example, some that
		didn't take an int directly as a hash value, and i missed a get_multi w/out hashes.
	-- removed java.net.Socket reference from MemCachedClient, SockIO has a new constructor which
		takes hostname and port number
	-- switched to three part version number

27 Sep 2003
	-- released as version 0.3
	-- Compression, for strings/stringified numbers, this is compatible w/ perl
		Serialized objects are incompatible w/ perl for obvious reasons. :)
	-- Added PORTABILITY file, to include information about using the client
		with various JVM's
	-- Updated string parsing to StreamTokenizer rather than regexp's in an 
		effort to get sablevm to like the client

24 Sep 2003
	-- released as version 0.2
	-- Serialization works
	-- Possible BUG: Only the lower byte of the characters of keys are sent
		This is only a problem if the memcache server can handle
		unicode keys. (I haven't checked)
	-- Server Failures handled gracefully
	-- Partial Javadoc

23 Sep 2003
	-- Initial Release 0.1
	-- Storing and Retrieving numbers and strings works
