+        * Added Shinomori's changes to Dissonance -- don't increment the timer again

+          if the target has died [celest]

+        * Changed some nullpo checks back to normal null checks -- in some situations

+          it would be normal to get a NULL [celest]

+        * Changed some nullpo checks to print some debug information [celest]

+        * Added some sd checks before calling pc_blockskill [celest]

+        * Added Dino9021's fix for SQL char's friend list updating [celest]

+        * Fixed a crash if the player invited to join a guild is not online, thanks to

+          Alex14 [celest]

+        * Find the guild invitation sender first before clearing its ID [celest]

+

         * Added 2 new script commands to support 2/15's cards patch... most of the
