+# Version 0.1.1 (December 15, 2023)
+* Fixed bugs in issues #21 and #26.
+* Added remaining operators defined in SMT-LIB QF_BV (bitvector) specification (issue #22)
+* Add `^` for square
+* Correctly promote expressions containing mixed `BoolExpr`, `IntExpr` and `RealExpr` types. When a Boolean variable `z` is used in an arithmetic expression, it is rewritten to `ite(z 1 0)` (int) or `ite(z 1.0 0.0)` (real), which matches Z3's behavior. The SMT-LIB functions `to_real` and `to_int` are used to convert mixed `IntExpr`s and `RealExpr`s.
