Name        : z3
Product     : Fedora 21
Version     : 4.4.0
Release     : 1.fc21
URL         : https://github.com/Z3Prover/z3
Summary     : Satisfiability Modulo Theories (SMT) solver
Description :
Z3 is a satisfiability modulo theories (SMT) solver; given a set of
constraints with variables, it reports a set of values for those
variables that would meet the constraints.  The Z3 input format is an
extension of the one defined by the SMT-LIB 2.0 standard.  Z3 supports
arithmetic, fixed-size bit-vectors, extensional arrays, datatypes,
uninterpreted functions, and quantifiers.

Update Information:

Upstream notes on version 4.4.0:
- New feature: Support for the theory of floating-point numbers. This comes in the form of logics (QF_FP and QF_FPBV), tactics (qffp and qffpbv), as well as a theory plugin that allows theory combinations. Z3 supports the official SMT theory definition of FP (see http://smtlib.cs.uiowa.edu/theories/FloatingPoint.smt2) in SMT2 files, as well as all APIs.
- New feature: Stochastic local search engine for bit-vector formulas (see the qfbv-sls tactic).  See also: Froehlich, Biere, Wintersteiger, Hamadi: Stochastic Local Search for Satisfiability Modulo Theories, AAAI 2015.
- Upgrade: This release includes a brand new OCaml/ML API that is much better integrated with the build system, and hopefully also easier to use than the previous one.
- Fixed various bugs reported by Marc Brockschmidt, Venkatesh-Prasad Ranganath, Enric Carbonell, Morgan Deters, Tom Ball, Malte Schwerhoff, Amir Ebrahimi, Codeplex users rsas, clockish, Heizmann, susmitj, steimann, and Stackoverflow users user297886.
