Version 0.3.1 (2020-04-17)
==========================
* Static casts were deprecated as their use case was unclear.
Version 0.3.0 (2019-10-01)
==========================
* The behavior of static casts was changed: now they return
`Option`, but an implementation should either always return `Some`
or always return `None`.
* Bug fix: checked casts from floating-point to wrapped integers
were panicking for infinite or NaN.
Version 0.2.0 (2019-09-10)
==========================
* The old `*As` traits were renamed to `*Cast`.
* New more convenient `*As` traits were added.
Version 0.1.0 (2019-09-09)
==========================
* Conversions between integers and floating-point numbers.
* Checked, saturating, wrapping and overflowing conversions.
* Static conversions when the conversion cannot fail.
* Rounding conversions from floating-point numbers to integers using `Round`.
