Version 0.4.3 (unreleased)
==========================

  * The *fixed* crate now requires rustc version 1.34.0 or later.
  * The following methods are now `const` functions:
      * `min_value`, `max_value`, `from_bits`, `to_bits`
	  * `count_ones`, `count_zeros`, `leading_zeros`, `trailing_zeros`
        `rotate_left`, `rotate_right`
	  * `wrapping_neg`, `wrapping_add`, `wrapping_sub`,
        `wrapping_mul_int`, `wrapping_shl`, `wrapping_shr`
	  * `overflowing_neg`, `overflowing_add`, `overflowing_sub`,
        `overflowing_mul_int`, `overflowing_shl`, `overflowing_shr`
      * `is_positive`, `is_negative`

Version 0.4.2 (2019-08-16)
==========================

  * The new methods [`from_num`] and [`to_num`] together with their
    checked versions were added to all fixed-point numbers.
  * The methods `from_fixed`, `to_fixed`, `from_int`, `to_int`,
    `from_float`, and `to_float`, and their checked versions, were
    deprecated.
  * The new method [`from_num`][`Wrapping::from_num`] was added to the
    [`Wrapping`] wrapper.
  * Bug fix: parsing of decimal fractions was fixed to give correctly
    rounded results for long decimal fraction strings, for example
    with four fractional bits, 0.96874999… (just below 31⁄32) and
    0.96875 (31⁄32) are now parsed correctly as 0.9375 (15⁄16) and 1.0.

Version 0.4.1 (2019-08-12)
==========================

  * All fixed-point types now implement `FromStr`.
  * The methods `from_str_binary`, `from_str_octal` and `from_str_hex`
    were added.

Version 0.4.0 (2019-08-08)
==========================

  * The *fixed* crate now requires rustc version 1.31.0 or later.
  * The `traits` module was added, with its traits `Fixed`,
    `FixedSigned`, `FixedUnsigned`, `FromFixed`, `ToFixed`,
    `LossyFrom` and `LossyInto`.
  * The `saturating_neg` method was added to all fixed-point numbers,
    and the `saturating_abs` method was added to signed fixed-point
    numbers.
  * The `consts` module was added.
  * The `signum` method now wraps instead of panics in release mode.

Incompatible changes
--------------------

  * The sealed traits `Int` and `Float` now have no provided methods;
    the methods in the old implementation are now provided by
    `FromFixed` and `ToFixed`.
  * Deprecated methods were removed.

Version 0.3.3 (2019-06-27)

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

    fixed-point numbers.

==========================

  * The crate can now be used without the standard library `std`.

    the same underlying integer type.

    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)
==========================

    for the number of fractional bits.
  * Many methods and trait implementations available for primitive
    integers are now also supported by the fixed-point numbers.
