0.1.0   Wed, 17 Jan 2001 19:11:40 +0000
        First release

0.1.1   Thu, 18 Jan 2001 15:52:08 +0000
        Change license from GPL to GPL/BSD, add AUTHORS

0.1.2   Thu, 18 Jan 2001 19:38:30 +0000
        Add ChangeLog
        md5_step_4_f optimised
        md5_step_4_g just calls md5_step_4_f after shuffling arguments

0.1.3   Fri, 19 Jan 2001 20:03:02 +0000
        Add md5_size which allows you to specify the size giving a
          significant speed improvement. Very useful for files.
        Add k to i earlier
        Most of md5sum written. Just -v to do I think.

0.1.4   Sun, 21 Jan 2001 00:00:30 +0000
        Change multiplies and divs to shifts
        Precalculate the lists like 7x+1 mod 16
        Wrote a simple README (needs more work)
        Finished md5sum (renamed to md5sum.dpkg) ignoring binary mode
        Use a Word64 instead of an Integer and doing mods all over the
            place for the size

0.1.5   Wed,  7 Feb 2001 12:11:28 +0000
        447 fixed to 440, although as we're using bytes it wouldn't
            have made a difference
        Fixed Word64 usage so it works with hugs

0.1.6   Wed,  7 Feb 2001 13:39:54 +0000
        replicate' removed as redundant (as of 0.1.5)
        Calculate the size as we go so we only go through the list once
        md5_size removed

0.1.7   Thu,  8 Feb 2001 17:16:38 +0000
        Created md5{,s,i}M? for functions returning an ABCD, string
        and integer, each with a monadic version. Altered the test
        program to use the monadic function in the test and stdin cases.

0.1.8   Fri,  9 Feb 2001 13:48:19 +0000
        I think md5iM? now returns the correct integer - I hate
            endianness.
        Commented everything.

0.2.0   Mon, 12 Feb 2001 23:24:07 +0000
        Added an MD5 class. Currently String and ([Word32], Zord64) are
            instances. Not sure all the definitions are correct for the
            latter, especially when length `mod` 8 /= 0.

0.2.1   Tue, 13 Feb 2001 21:58:15 +0000
        Removed finished from the class and made leng work properly to
            compensate.
        Implemented an instance for [Bool].
