version 3.13 (2007-11-21) Made rabbit sleep longer when it is idle. Fixed
             a problem with zero length resources (apple store style
	     sheets). Added some more javadoc and comments (Rick).
	     Improved the handling of localhost accesses for status pages
	     (robo). Some code cleanup (Rick and robo). Added some more
	     comments to the code (Rick). Added some technical
	     documentation describing the thread usage of rabbit. Added
	     some code to avoid NPE in SelectorRunner during shutdown of
	     proxy (bug from Vladimir). Code cleanup: remove unneeded
	     imports and unused variables.

version 3.12 (2007-10-15) Removed some unused code from the zip handling.
	     Tried to add a workaround for the broken linux/epoll
	     selector (in java 6u1, 6u2 and 6u3).

version 3.11 (2007-09-17) Made it possible to configure the minimum image
	     size to convert. Fixed a problem with html parsing and
	     lingering rest blocks. Made the AdFilter handle a few more
	     cases of bad html (fixes http://linuxtoday.com/). Made sure
	     that the selector de-registers unhandled sockets nicely. Some
	     code cleanup in cache validation (Rick). Moved socket handler
	     deregistration to SelectorRunner to make sure that no handler
	     misses to deregister (and thus causing cpu spin on the
	     selector). Fixed the problem with proxy chaining and ssl
	     handling. Rick added deflate support. Added more debug
	     logging. Fixed a problem with gzip unpacking hangin if the
	     first resource block was very short. 
	
version 3.10 (2007-07-09) Fixed a few problems found by findbugs/1.2.1. 
             Fixed a typo in the config for SQLProxyAuth (Luis). Tried to
	     make the html filter nicer to javascript when javascript is
	     sent as mime type text/html. Fixed a problem with selection
	     key being cancelled when handlers run in the thread pool
	     (robo, found by Vladimir).

version 3.9 (2007-06-11) Java/6 is now needed. Added the possibility for
	    html filters to turn caching off for the current resource,
	    rick+robo. Updated the cache to also count size of header
	    files. Added Ricks patches to supress favicon error logs,
	    getRequestURI in Connection and updated the HttpSnoop filter
	    with a parameter to only print status lines. Added an example
	    filter that can be used to set request or response
	    headers. Updated FilterHandler/HtmlParser to handle different
	    character sets. Made it possible to set the default charset
	    for FilterHandler (rfc2616 say ISO-8859-1, but some people
	    want otherwise). Fixed a NPE that could occur if
	    DontFilterFilter was badly configured. Added ".js" to the list
	    of file types not to parse, they are usually javascript, but
	    can sometimes be sent as "text/html".

version 3.8 (2007-03-07) Added a RevalidateFilter that can be used to make
            sure that rabbit always revalidates some (or all) resources. 
	    Added deny lists handling to conf/access and AccessFilter. 
	    Added Ricks patch to give a nicer host not found page. Made
	    the Selector information more readable. Added some more
	    information to the status page. Fixed a problem with web
	    connections resources reading too much data (when pipelining
	    requests). Added Ricks patches for easier handling of mime
	    type handlers: remove whitespace after ';' and allow '?' to 
	    indicate one optional character.

version 3.7 (2007-01-08) Fixed a NPE that could happen when caching http
            headers. Fixed a problem where rabbit got a SIOBE for requests
	    for "". Fixed a problem with zero sized Content-Length in
	    uploads. Fixed a rare NPE in BaseHandler.finish.

version 3.6 (2006-11-17) Added a filter to remove "Accept-Encoding: gzip",
            useful if you want rabbit to filter more sites. Fixed a
	    problem with restart when select fails. Updated dnsjava to
	    version 2.0.2. Rewrote gzip packing and unpacking. Added the
	    possibility to unpack gzipped resources. Changed the config
	    for handlers to be id based, which means that it is possible
	    to configure the handler differently based on image type or
	    content encoding. Fixed a memory leak in the
	    ConnectionHandler. Fixed a problem where file transfers would
	    loop trying to write instead of shutting down. 
	
version 3.5 (2006-09-17) Fixed a problem where GZipHandler failed to keep
            track of how much data it had read and thus causing rabbit to
	    refetch resources. Rework how cache handling works, it is much
	    faster now. Removed most locks on the returned tasks list. 
	    Some small performance fixes all over, both for memory and cpu.

version 3.4 (2006-08-28) Added a buffer cache, direct buffers will now be
            reused and rabbit will cause less GC. Web connections that are
	    flagged for keep alive, but have outstanding data to read will
	    now be closed. 
	
version 3.3 (2006-07-30) Lots of work with the selector registration to be
            able to handle client side pipelining. Fixed a lot of findbugs
	    flagged problems. Fixed problems with some partial downloads. 

version 3.2 (2006-05-27) Fixed a NPE in BaseHandler.finish:208. Fixed a
            workaround for a CCE in HttpProxy.handleSelects:432. Fixed a
	    problem with GZipHandler and already compressed streams.

version 3.1 (2006-04-06) Upstream proxy should work again. AdFilter has a
            better default for adlinks. Fixed config of ImageHandler that
	    was ignored. Infinite loop bug in RandomCacheResourceSource fixed.

version 3.0 (2006-03-28) BaseHandler will no longer chunk resources if the 
            content length is known. Set sockets to use TcpNoDelay
	    (Nagle's algorithm). Started to redo the pipeline handling. 
	    Implemented block listener handling to file reousrces. Cache
	    will now use buffered streams. Added LogRotator again.

version 3.0 pre-release (2006-02-13) first pre release of rabbit
            3.0. RabbIT now uses java.nio for all network talk and most of
	    the internal systems uses threads for long time operations.
