  • The obsolete and unused 'direct' parameter was removed.
  • The program no longer recurses into main() when an unknown algorithm is selected.
  • A bug in the handling of hexstrings in Python3 was fixed.
  • The input to the CRC routines can now be bytes or strings.
  • The symbol table was reorganised. was updated.

New in version 0.8 (January 5th, 2013)

  • Adds the experimental bitwise-expression generator target.
  • Allows you to specify the --include option multiple times.
  • Completely revisited and reworked documentation.
  • Allows you to abbreviate the names of the algorithms.
  • Minor documentation changes.

New in version 0.7.11 (October 22nd, 2012)

  • This version improves Python3 compatibility. pycrc now requires Python 2.6 or later.
  • A wrong "check" value of the crc-64-jones model has been fixed.
  • sprintf() is now used for C89 code instead of snprintf().
  • The regression test script has been rewritten in Python.

New in version 0.7.10 (February 14th, 2012)

  • It adds the CRC models crc-12-3gpp, crc-16-genibus, crc-32-bzip2, and crc-64-xz.
  • It fixes some bad-looking generated C code, and cleans up some mistakes in the man page and some inefficient code in the CRC code generator.

New in version 0.7.9 (December 9th, 2011)

  • This release fixes a few smaller issues in the code generator.
  • It no longer includes stdint.h for C89/ANSI code, removes an unused variable missed in the last version, and fixes a bug with C89 code for 64-bit CRCs.

New in version 0.7.7 (February 14th, 2011)

  • Substituted the deprecated function atoi() with int(). Closes issue 3136566. Thanks to Tony Smith.
  • Updated the documentation with a Windows-style call of the python interpreter.
  • Fixed a few coding style issues found by pylint and pychecker.

New in version 0.7.6 (October 22nd, 2010)

  • This version fixes a minor bug in the command line parsing of the generated main function.
  • The python code uses integer division for Python3 compatibility.
  • A complete rewrite of the internal macro language and code generator.

New in version 0.7.5 (March 29th, 2010)

  • The table-driven algorithm can handle widths that are not byte-aligned as well as widths less than 8.
  • Removed half-baken and confusing --direct option. Closes issue 2938846.
  • Code clean-up; the generated C code should no more generate warnings about unused variables.

New in version 0.7.4 (January 25th, 2010)

  • Set xmodem parameters equal to zmodem params.
  • Changed the xor-in value of the crc-64-jones model.
  • Added crc-16-modbus model. Closes issue 2896611.
  • pycrc now writes a warning message if an even polynom is used.
  • Fix for unused variable argv. Closes issue 2893224. Thanks to Marko von Oppen.
