    * crc_symtable.py:
    The table-driven code for polynomials of width < 8 using a table index
    width < 8 was producing a wrong checksum.
    Thanks to Radosław Gancarz.

2013-12-23  Thomas Pircher   <tehpeh@gmx.net>

    * crc_symtable.py:
    Small cleanups.

    * test/test.py:
    Small cleanups.
    Added a tests for special cases. For now, added crc-5 with non-inverted
    input. This test is currently failing.

2013-12-20  Thomas Pircher   <tehpeh@gmx.net>

    * crc_symtable.py:
    * test/test.py:
    Updated the generated code to cope with big Widths (>32 bits) on 32 bit
    processors.
    Since C89 does not give a way to specify the minimum length of a data type,
    the test does not validate C89 code using Widths > 32.
    For C99, the uint_fastN_t data types are used or long long, if the Width is
    unknown.

2013-07-25  Thomas Pircher   <tehpeh@gmx.net>

    * crc_opt.py:
    Removed warning about even polynomials. As Lars Pötter rightly pointed out,
    polynomials may be even.

    * doc/pycrc.xml:
    Added a caveat emptor about even polinomials.

2013-03-31  Thomas Pircher   <tehpeh@gmx.net>

    * README.md:
    Esplicitly stated that the output of pycrc is not considered a substantial
    part of the code of pycrc.

    * crc_symtable.py:
    Re-organised the symbol table: grouped the code by functionality, not by
    algorithm.

2013-02-25  Thomas Pircher   <tehpeh@gmx.net>

    * pycrc.py:
    * crc_algorithms.py:
    The input to the CRC routines can now be bytes or strings.

    * crc_models.py:
    * qm.py:
    * doc/pycrc.xml:
    * test/test.py:
    * test/performance.sh:
    Merged (private) bitwise-expression branch to main.
    This adds the highly experimental bitwise-expression (bwe) code generator
    target, which might one day be almost as fast as the table-driven code but
    much smaller.
    At the moment the generated code is bigger and slower than any other
    algorithm, so use at your own risk.

2013-01-02  Thomas Pircher   <tehpeh@gmx.net>

    * crc_opt.py:

    Renamed abbreviations to bbb, bbf, tbl.

2012-11-18  Thomas Pircher   <tehpeh@gmx.net>

    * crc_opt.py:
    It is possible now to abbreviate the algorithms (bbb for bit-by-bit,
    bbf for bit-by-bit-fast and tbl for table-driven).
    Added the list of supported CRC models to the error message when an
    unknown model parameter was supplied.

    * doc/pycrc.xml:
    Documented the possibility to abbreviate the algorithms. Minor
    improvements.

    * test/test.py:
    Deleted test.sh shell script and replaced it with test.py.

#
# Version 0.7.10, 2012-02-13
#

2012-02-08  Thomas Pircher   <tehpeh@gmx.net>

    * crc_symtable.py:
    Bad-looking C code generated; make sure the bit-by-bit(fast) code does not
    contain two instructions on one line. Thanks to "intgr" for the fix.

    * crc_symtable.py:
    Some small code clean-up: use set() when appropriate.

2011-12-19  Thomas Pircher   <tehpeh@gmx.net>

    * crc_symtable.py:

#

2011-07-10  Thomas Pircher   <tehpeh@gmx.net>

    * crc_symtable.py:
    When generating C code for the C89 or ANSI standard, don't include <stdint.h>.
    This closes issue 3338930

    * crc_symtable.py:
    If no output file name is given while generating a C file, then pycrc will
    #include a hypothetical pycrc.h file instead of a stdout.h file.
    Also, added a comment on that line to make debugging easier.

#
# Version 0.7.5, 2010-03-28
#

2010-03-27  Thomas Pircher   <tehpeh@gmx.net>

    * crc_symtable.py:
    C/C++ code can now be generated for the table-driven algorithm with widths
    that are not byte-ligned or less than 8.
    This feature was heavily inspired by a similar feature in Danjel McGougan's
    Universal Crc (http://mcgougan.se/universal_crc/).

    W A R N I N G: introduced new variable crc_shift, member of the crc_cfg_t
                   structure, that must be initialised manually when the width
                   was undefined during C/C++ code generation.

2010-03-27  Thomas Pircher   <tehpeh@gmx.net>

    * crc_opt.py, crc_algorithms.py:
    Python implementation of the table-driven algorithm can handle widths less
    than 8.
    * crc_symtable.py:
    Suppressed warnings of unused cfg structure on partially defined models.

2010-03-26  Thomas Pircher   <tehpeh@gmx.net>
