    A new Mystery has been revealed!

 they had too many active states.
- Fixed two issues where players could stack auras in an unintended way.


    Minor Bugs
   
- Uber Mephisto now checks for both Uber Baal and Uber Diablo to be killed
 before spawning summoned minions (Before he would only check for Uber Baal).
- The game will no longer stop and then restart the game music after the
 window loses and then regains focus.

 windowed mode when it lost focus.
- Fixed an issue where the game window wouldn't center properly when it
 was created.
- Fangskin should now properly drop loot in Hell difficulty.

 it was resurrected.

 a mercenary and you unequipped one, the aura from the remaining
 item never became active.
- Fixed an issue where the Paladin class runeword 'Principle' wasn't
 having all of its stats applied properly.
- Fixed an issue where the Paladin's Charge ability would become locked
 out if Holy Shield faded while charging.

 out if they were hit when they started to leap.


    Specific changes/improvements    

- Respecialization is now possible! Completing the 'Den of Evil' quest
 will now additionally reward 1 free respec which can be saved. Players
 who have already completed this quest should receive 1 free respec in
 Hell difficulty.
- Increased the drop rate of high runes.
- Support for blit scaling in windowed mode. The game can now be
 maximized to the largest 4:3 resolution supported (hooray widescreen users).
- Some rare drop items now have an orange color. i.e. Runes and items
 required for Uber Tristam.
- Modified the gold bank limit to be a flat cap not bound by level.
- Removed the requirements to create a hardcore character.
- Greatly reduced the explosion damage dealt by Fire Enchanted monsters.

 to a unique key: Normal 'R', Nightmare 'N', and Hell 'H'.
- The 'Enter Chat' Button in the battle.net waiting room is now
 bound to the 'Enter' key.
- Added the windows system buttons to the game window (MIN, MAX, CLOSE).
- Added new command line parameter '-nofixaspect' which allows users to
 not fix the aspect ratio to 4:3 when maximizing in windowed mode.
 This lets the game 'stretch' to fill your monitor.

 in background.
