• New Keyword CONSTANT is used to modify ANY variable declaration (that is GLOBAL, SHARED, INSTANCE, LOCAL) into a constant value that is evaluated at compile time, not runtime. 
• New Keyword READONLY is used to modify an INSTANCE variable (ONLY)  into a value that has PUBLIC access for reading and PRIVATE access for writing.
• Now support the new ProtectedRead/Write, PrivateRead/Write, and SystemRead/Write restrictive access keywords on property definitions.  These are replacing the READONLY property modifier, and its prior successor, ProtectedRead and PublicRead.
• New keywords have been added that may be applied to function and event calls.
• Events may be called like functions with the use of a new keyword
• You may post events and functions for later execution
• You may call dynamically bound functions and events
• When you have a local, shared, or instance variable hiding a global variable you can now reference the global by placing "::" (double colon) in front of it, for example:

::g_var

• Message.processed reimplemented.  There are cases where we need this attribute for compatiblity reasons.
