 <h2>Changes</h2>
 <ul>
+<li>2.00 beta 9<ul>
+<li>Removed FFNoLog and replaced it with FFSetLogLevel and FFGetLogLevel, the default logging is now also set to quiet, the magical numbers to supply it can be found in avutil/log.h</li>
+<li>Updated FFmpeg to rev X</li>
+</ul></li>
+
 <li>2.00 beta 8<ul>
 <li>Improved the audio decoding quality a lot by adding a simple cache, no more seeking is done when playing a file linearly and pops and other artifacts should be much more uncommon</li>
 <li>Fixed a bug that would most of the time drop frame 0 and sometimes frame 1</li>
