Turbine's Tolero has posted the substantial patch notes on the official Dungeons and Dragons Online forums. Update 9 is currently strutting its stuff on the Lamannia test server, and among the new features are updated combat animations, a Saltire District adventure pack, and a host of tweaks to a lengthy list of spells and abilities.
The list is so long, in fact, that we couldn't reproduce it here, so head to the boards and see for yourself. Update 9 also boasts a couple of class changes, notably additional early level spell points for Rangers and Paladins as well as a new Echoes of Power effect. When a player with the magical training feat is low on spell points, Echoes of Power will automatically come to the rescue with a regeneration effect.
