=================
* SMT-LIB support for abs, to_real, to_int, is_int
+* Expr::substitute() now capable of substituting operators (e.g.,
+ function symbols under an APPLY_UF)
* Support in linear logics for /, div, and mod by constants.
+* Support for TPTP's TFF and TFA formats.
* We no longer permit model or proof generation if there's been an
intervening push/pop.
* Increased compliance to SMT-LIBv2, numerous bugs and usability issues
