Version 0.3.3 (2019-06-27)
==========================

  * Conversions to/from `isize` and `usize` were added.

Version 0.3.2 (2019-02-27)
==========================

  * The `Wrapping` wrapper was added.

Version 0.3.1 (2019-02-07)
==========================

  * Reimplement `From<bool>` for all fixed-point types which can
    represent the integer 1. This was inadvertently removed in 0.3.0.

Version 0.3.0 (2019-02-03)
==========================

  * Incompatible change: the return type of `to_int` is now generic.
  * Incompatible change: the `Int` trait implementation for [`bool`]
    was removed.
  * The new method `to_fixed` was added.
  * The new methods `checked_to_fixed`, `checked_to_int`,
    `saturating_to_fixed`, `saturating_to_int`, `wrapping_to_fixed`,
    `wrapping_to_int`, `overflowing_to_fixed` and `overflowing_to_int`
    were added.
  * The methods `from_fixed`, `to_fixed`, `checked_from_fixed`,
    `checked_to_fixed`, `saturating_from_fixed`,
    `saturating_to_fixed`, `wrapping_from_fixed`, `wrapping_to_fixed`,
    `overflowing_from_fixed` and `overflowing_to_fixed` were added to
    the `Int` trait.
  * The methods `from_fixed`, `to_fixed`, `checked_to_fixed`,
    `saturating_to_fixed`, `wrapping_to_fixed` and
    `overflowing_to_fixed` were added to the `Float` trait.
  * `PartialEq` and `PartialCmp` are now implemented for all
    combinations of fixed-point numbers and primitive integers.
  * The methods `int_bits` and `frac_bits` were deprecated and
    replaced by the methods `int_nbits` and `frac_nbits`.

Version 0.2.1 (2019-01-29)
==========================

  * Bug fix: the `from_fixed` and `from_int` methods (and their
    checked counterparts) could return wrong values for negative
    values.
  * Bug fix: display was using one fractional digit less than
    required, thus yielding the same output for diffent fixed-point
    numbers.

Version 0.2.0 (2019-01-29)
==========================

  * Incompatible change: The method `from_int` was change to accept a
    generic parameter.
  * The new methods `from_fixed`, `checked_from_fixed`,
    `saturating_from_fixed`, `wrapping_from_fixed` and
    `overflowing_from_fixed` were added.
  * The new methods `checked_from_int`, `saturating_from_int`,
    `wrapping_from_int` and `overflowing_from_int` were added.
  * The new methods `from_float`, `checked_from_float`,
    `saturating_from_float`, `wrapping_from_float` and
    `overflowing_from_float` were added.
  * The new method `to_float` was added.
  * The methods `from_f16`, `from_f32`, `from_f64`, `to_f16`, `to_f32`
    and `to_f64` were deprecated.
  * The `to_int` method was fixed to truncate fractional bits as
    documented for negative values.
  * The new methods `ceil`, `floor`, `round`, `checked_ceil`,
    `checked_floor`, `checked_round`, `saturating_ceil`,
    `saturating_floor`, `saturating_round`, `wrapping_ceil`,
    `wrapping_floor`, `wrapping_round`, `overflowing_ceil`,
    `overflowing_floor` and `overflowing_round` were added.
  * The methods `to_int_ceil`, `to_int_floor` and `to_int_round` were
    deprecated.

Version 0.1.6 (2019-01-27)
==========================

  * Optional serde support was added.

Version 0.1.5 (2019-01-26)
==========================

  * Lossless infallible conversions between fixed-point numbers and
    numeric primitives are now supported using `From` and `Into`.
  * A new module `types` is available with aliases for all supported
    fixed-point numbers.

Version 0.1.4 (2018-11-29)
==========================

  * Division is now implemented for `FixedI128` and `FixedU128`.

Version 0.1.3 (2018-08-23)
==========================

  * The `f16` feature was added, and new methods `from_f16` and
    `to_f16` were added.

Version 0.1.2 (2018-08-15)
==========================

  * The crate can now be used without the standard library `std`.
  * New methods `from_f32` and `from_f64` were added.
  * New methods `is_positive` and `is_negative` were added to signed
    fixed-point numbers.

Version 0.1.1 (2018-08-11)
==========================

  * Comparisons are now supported between all fixed-point numbers with
    the same underlying integer type.
  * New static methods `int_bits` and `frac_bits` were added.
  * New methods `from_int`, `to_int`, `to_int_ceil`, `to_int_floor`
    and `to_int_round` were added.
  * New methods `int` and `frac` were added.
  * Support for multiplication and division by integers was added.

Version 0.1.0 (2018-08-10)
==========================

  * `Unsigned` constants provided by the *typenum* crate are now used
    for the number of fractional bits.
  * Many methods and trait implementations available for primitive
    integers are now also supported by the fixed-point numbers.
