We now use Steel Bank Common Lisp (SBCL) as the host system for
Specware on Linux and Mac OS X. This improves Specware’s speed and
supports Specware for Mac OS X on Intel.
Miscellaneous bug fixes.

Guarded patterns (2.7.2)
Special syntax for monads (2.6.16)
Underscore (_) is a wild card in qualifications in translations (184.108.40.206)
Sum and Quotient types are only allowed at the top-level, i.e., on the right-hand side of type definitions (2.4.3)
New combined op and def syntax to facilitate sub-type definition (2.4.4). E.g.,
op [a] nth (l : List a, i : Nat | i < length l) : List a = ...
