 Wishlist?
 
 Known bugs:
-Return to game in pause menu are sometimes broken. (It seldom happens, and is 
-very hard to catch!)
 One part of Level 3 fails randomly (really randomly?).
-~~infinity CLR~~(debug purpose. I can't pass those levels with out
-this)
 
 Wishlist:
 Make more data stored in score.cfg.
 Replace some boring levels.
-Built-in help pages.
 In-game music bring back.
 ~~Now Playing(Music Room)~~
 ~~BLR script virtual machine~~(long long-term! probably the core
 of next BLR.)
 
 Pre-Released versions:
+0.9.1-2 (r91)
+Add built-in help.
+Now the pause menu should be fixed...
+Compress resources again.
+
 0.9.1-1 (r90)
 Fix a bug in the credit scene.
 Now the pause menu shouldn't be broken now...(It's so hard to reproduce
