30 | * 2014-01-11: corrected CRC-40/GSM, added alias CRC-8/AES | |
31 | * 2013-10-14: added CRC-13/BBC and six cdma2000 algorithms | |
32 | * 2013-06-11: ensure BMP_BIT is an integer constant to compile presets | |
33 | * 2013-01-20: big polynomials autogenerated, corrected CRC-82/DARC | |
34 | * 2012-07-19: added CRC-8/EBU | |
35 | * 2012-07-16: added CRC-15/MPT1327 | |
36 | * 2012-05-25: removed CRC-1/PARITY-EVEN, CRC-1/PARITY-ODD | |
37 | * 2012-04-12: added model CRC-31/PHILIPS | |

39 | * 2011-08-28: added model CRC-64/XZ | |
40 | * 2011-04-30: added models CRC-16/TMS37157 and CRC-A, and alias CRC-B | |
41 | * 2011-02-10: made preset models ANSI C compliant | |
42 | * 2011-01-17: fixed ANSI C warnings (except preset models) | |
43 | * 2011-01-01: added mbynum(), mcount() | |
44 | * 2010-12-26: renamed CRC RevEng | |
45 | * 2010-12-18: minor change to mtostr() output format | |
46 | * 2010-12-15: added mcmp(), mmatch() | |
