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
~> 12.0for ruby 2.6. -
Fixed a bug in
ext/digest/Rakefilewhich prevented digest-crc from being installed on systems where C extensions could not be successfully compiled. -
Rake’s
rubymethod, which in turn calls rake’sshmethod, raises aRuntimeErrorexception when the ruby command fails, causing rake to exit with an error code. Instead, rescue anyRuntimeErrorexceptions 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).
