I've done a few "diff" updates lately, so this 4.1.4 is actually a 4.1.2 diff-upgraded first to 4.1.3 and then again to 4.1.4 instead of doing the full upgrade. There's still one file that needs to be tweaked (b2evolution/blogs/inc/_ext/xmlrpc/_xmlrpc.inc.php) to remove the compression, by simply commenting out the assignment on line 911 and allowing it to use an empty array.

// $this->accepted_compression = array('gzip', 'deflate');

The only thing leaving the line alone seems to break is when the app requests updates to the crowd-sourced anti-spam list. When the accepted_compression is set with the line above, it fails saying it can't be decrypted, but when it's commented-out, the file is received and handled appropriately. Sure, maybe it isn't compressed enroute, but it arrives nonetheless.

It's a little odd, as the server, including the Apache and PHP have both gzip and deflate built-in. Still, small tweak to make for an easy update to the software.
