Version 1.9.0 (unreleased) ========================== * The following method was added to all fixed-point numbers, to the [`Fixed`][tf-1-9] trait, and to the [`Wrapping`][w-1-9] and [`Unwrapped`][u-1-9] wrappers: * [`is_zero`][f-iz-1-9] * The following associated types were added to the [`Fixed`][tf-1-9] trait: * [`Signed`][tf-s-1-9], [`Unsigned`][tf-u-1-9] * The following traits from the [*bytemuck* crate] were implemented for all fixed-point numbers, added as supertraits to the [`Fixed`][tf-1-9] trait, and implemented for the [`Wrapping`][w-1-9] and [`Unwrapped`][u-1-9] wrappers. * [`Zeroable`][bm-z-1], [`Pod`][bm-p-1] * [`TransparentWrapper`][bm-tw-1] Compatibility notes ------------------- * Now the [`Debug`] implementation for [`Wrapping`][w-1-9] outputs the value only without `"Wrapping()"`, and the [`Debug`] implementation for [`Unwrapped`][u-1-9] outputs the value only without `"Unwrapped()"`. * The [`LeEqU8`][leu8-1-9], [`LeEqU16`][leu16-1-9], [`LeEqU32`][leu32-1-9], [`LeEqU64`][leu64-1-9] and [`LeEqU128`][leu128-1-9] traits now have a `'static` constraint. This should have no practical side effects, since these traits are a convenience feature and already have the [`Unsigned`][uns-1-9] marker trait as a supertrait, and the types that implement [`Unsigned`][uns-1-9] are `'static`. * The [`FixedOptionalFeatures`][fof-1-9] trait was not sealed, which was as an oversight. Now it is sealed, and the documentation explicitly states that the trait should not be used directly.
