• The class method now works in all cases. You can now compare classes with == and ask their hash value.
• Block variables can now shadow local variables.
• Range(B, E) is now Range(T).
• Added Number::[]. Now you can do Int64[1, 2, 3] instead of [1_i64, 2_i64, 3_u64].
• Better detection of nilable instance variables, and better error messages too.
• Added Crypto::Blowfish (thanks @akaufmann)
• Added Matrix (thanks @exilor)
• Added CallConvention attribute for funs.
• Macros: added constants so you can inspect a type's constants at compile time.
• Macros: added methods, which lists a type's methods (without including supertypes).

• Many more small additions and bug fixes.
