### 0.7.0 / 2025-01-28
* Added {Digest::CRC64NVMe}.
* Added {Digest::CRC.implementation}.
* Reduced duplicate code.
### 0.6.5 / 2023-07-03
* Corrected the implementation of {Digest::CRC5}.
* Make `digest-crc` Ractor-safe.
### 0.6.4 / 2021-07-14
* Silence potential method redefinition warnings when loading the C extensions.
(@ojab)
### 0.6.3 / 2020-12-19
* Broaden rake dependency to >= 12.0.0, < 14.0.0` for ruby 2.7, which includes
rake 13.x.
### 0.6.2 / 2020-12-03
* Lower the rake dependency to `~> 12.0` for ruby 2.6.
* Fixed a bug in `ext/digest/Rakefile` which prevented digest-crc from being
installed on systems where C extensions could not be successfully compiled.
* Rake's `ruby` method, which in turn calls rake's `sh` method, raises
a `RuntimeError` exception when the ruby command fails, causing rake to
exit with an error code. Instead, rescue any `RuntimeError` exceptions and
fail gracefully.
### 0.6.1 / 2020-07-02
* Fix installation issues under bundler by adding rake as an explicit dependency
(@rogerluan).
### 0.6.0 / 2020-07-01
* Implement _optional_ C extensions for all CRC algorithms, resulting in an
average performance improvement of ~40x. Note, if for whatever reason the
C extensions cannot be compiled, they will be skipped and the pure-Ruby
CRC algorithms will be used instead. If the C extensions were successfully
compiled, then they will be loaded and override the pure-Ruby CRC methods with
the C equivalents.
* Alias {Digest::CRC16QT} to {Digest::CRC16X25}, since they are effectively the same (@dearblue).
* Fix {Digest::CRC32::WIDTH} (@dearblue).
