v0.19.0
What's Changed
Breaking changes
The new Expr replaces (old) Expr, Value, UnaryOp, BinaryOp, and TrinaryOp.
Where you may have used Value.float(x) previously, you should use Expr.float(x) now.
Similarly, Value.int and Value.str are moved and renamed to Expr.integer and Expr.string.
Hopefully other required changes are minor.
