  nice (0.9.11)
  
!   * maybeNull, a counterpart to notNull, can now be used to inform the compiler
!     that a value returned from Java libraries without retyping might be null,
!     in order to avoid a warning:
! 
        let prng = SecureRandom.getInstance("ARCFOUR");
! 
!       // Test if a bad implementation has returned null instead of an exception
        if(maybeNull(prng) == null) workaround();
! 
!   * Nullness analysis of assignments (RFE 681385) is implemented, so that the
!     compiler is more clever about when a value cannot be null.
      It is now possible to write:

      since Nice will detect that foo can't be null after the "foo = new Foo()",
      and will propagate this information outside of "if( foo == null )" checks.

        }
    * Added instanceof on option types. For instance 'x instanceof ?String'
      is equivalent to 'x == null || x instanceof String'.
    * Added binary integer literals. Examples: '0B1011' '0b1010_0000_0101_1111'.
    * Removed octal integer literals.
-   * Some error messages locate more precisely the source of the error.
-   * Generated bytecode is slightly more compact and references less "system"
-     Nice classes, so that those do not need to be automatically added to
-     generated jars.
-   * Exit the JVM with exit code 1 when the main program finishes with an
-     uncaught exception.
-   * Bug fixes (negative int hex literals, ...)
    * Automatic message is generated for assertions, containing
      the failed expression and location of the failed assertion
