### Changed

## [0.6.0] - 2018-10-24
### Added
- derive `Copy` for `Ulid`.
### Changed
- renamed `Ulid::new()` to `Ulid::generate()`.
- renamed `new_ulid_string()` to `generate_ulid_string()`.
- renamed `new_ulid_bytes()` to `generate_ulid_bytes()`.
### Removed
- derive `Default` for `Ulid`.
## [0.5.0] - 2018-08-09
### Added
- support for monotonic ULID values. See `next_monotonic` and `next_strictly_monotonic`.
### Changed
- updated dependencies.
## [0.4.1] - 2018-07-02
### Changed
- `description()` of `DecodingError` is now returning deprecation message like Rust 1.27.
## [0.4.0] - 2018-05-23
### Added
- `append_crockford_u64_tuple` and `parse_crockford_u64_tuple`.
### Changed
- A `Ulid` is now using a private `(u64, u64)` instead of being a `u128`. This is a non-breaking change.
- Using `rand 0.5.0` dependency.
- `append_crockford_u128` appends exactly 26 characters.
- `parse_crockford_u128` requires exactly 26 characters.
### Removed
- `append_crockford_u64` and `parse_crockford_u64`.
### Fixed
- Performance regression. This version is faster than `0.2.0`, even with `rand 0.4.2`.
## [0.3.0] - 2018-05-12
### Added
- Conversion of `Ulid` to and from `u128`.
- `append_crockford_u128` and `parse_crockford_u128`.
- `parse()` quickstart example.
- Derived `Ord`, `Eq` and `Hash` traits for `Ulid`.
- Proper `rusty_ulid` executable functionality including example usage documentation.
- Apache-2.0 license. This crate is now dual-licensed.
### Changed
- A `Ulid` is now using an `u128` instead of being a `(u64, u64)`. This is a breaking change
if you previously accessed the tuple elements directly.
- `DecodingError::InvalidChar` now contains a `char` instead of `Option<char>`.
- `append_crockford` was renamed to `append_crockford_u64`.
- `parse_crockford` was renamed to `parse_crockford_u64`.
- Panic message is now using proper ISO 8601 formatting for overflow datetime
`+10889-08-02T05:31:50.655Z`.
### Removed
- `Copy` trait from `Ulid`.
## [0.2.1] - 2018-04-10
### Fixed
- Documentation test of `Ulid::from_timestamp_with_rng`.
## [0.2.0] - 2018-04-10
### Added
- This changelog.
- Some criterion benchmarks. Run the benchmarks by executing `cargo bench`.
- `DecodingError::DataTypeOverflow` that is used by `parse_crockford` and
`Ulid::from_str` to indicate an overflow. Overflow means that the given string
contains more bits than the respective data type could handle.
### Changed
- `parse_crockford` can now parse strings of length 13 if they don't cause an `u64`
overflow. This means that `FZZZZZZZZZZZZ` can still be parsed but `G000000000000` will
cause a `DecodingError::DataTypeOverflow`.
Strings of length 14 or more still result in `DecodingError::InvalidLength`.
- `Ulid::from_str` is now returning properly detecting timestamp overflows. This means
that `7ZZZZZZZZZZZZZZZZZZZZZZZZZ` can still be parsed but `80000000000000000000000000`
will cause a `DecodingError::DataTypeOverflow`.
Strings of length different than 26 still result in `DecodingError::InvalidLength`.
- `Ulid::from_timestamp_with_rng` will now panic if `timestamp` is bigger than
`0xFFFF_FFFF_FFFF`.
This means that `Ulid::new()` will start to panic after `+10889-08-02T05:31:50.655Z`.
