Fixed

• missing return in wpscp_redirect_callback
• legacy $postid/$post_id typo bug natethelen @  http://wordpress.org/support/topic/232501

Added

• context based page fragment caching
• DB tracking for SuperCache files removing need for directory recursion
• robots.txt to hard-coded excluded uris
• detection of Widgets being changed in widget admin UI -> purge cache
• ignore TEST_COOKIE when deciding whether to SuperCache or not

Changed

• chunked output since (allegedly) sometimes echoing large strings performs badly. Never seen it myself TBH
• Moved ob_start to phase1

Removed

• nocache-home.php plugin - can be effected using ^/$ regex in Rejected URIs
