## 0.4.1

- Mark `AbsEq` as deprecated.
- Re-implement functions `next_up` and `next_down`, and expose them through the `utils` module.

## 0.4.0

### Add

- Add `is_positive()` and `is_negative()` to the `Signed` trait.

### Change

- `SquareRoot` and `CubicRoot` are moved to `dashu_base::math`.
- `AbsCmp` is renamed to `AbsOrd`.
- `FBig::square` and `Context::square` are renamed to `sqr`.

## 0.3.1

- Add trait `Inverse`.
- Implement `AbsCmp` and `AbsEq` for primitive types.

## 0.3.0

### Add

- Add trait `AbsCmp` and `AbsEq`
- Add trait `FloatEncoding` and implement it for `f32` and `f64`
- Add trait `Signed` and implement it for all signed primitive types
- Add conversion between `Sign` and `bool`
- Implement `Abs` for `f32` and `f64`
- Add types `error::{ConversionError, ParseError}` (originates from `dashu-int`)
- Add trait `SquareRoot`, `SquareRootRem`, `CubicRoot`, `CubicRootRem`
- Implement `EstimatedLog2` for `f32`, `f64` and signed integers

### Change

- `trailing_zeros` has been removed from the `BitTest` trait
- The definition of `BitTest::bit_len` has changed, and `BitTest` is now implemented for signed integers.

### Remove
