Version 8.28
Fixes a segfault on combination of -c n and -w options.
Fixes a free of free pointer on failed key extraction.

Version 8.27
If there is only one record, we still mention that there
   is no point in sorting only one record but we now exit
   successfully after writing out that record.
   This is desirable for non-interactive use.

Version 8.26
Case-folding was updated to Unicode 4.1.
Turkic case-folding has been added as an option.
The GUI now rolls up as it was beginning to take up
   too much real estate.

Version 8.25
The option of just checking whether the input is sorted is now available.
Conversion of stylistic variants now handles Hebrew presentation forms.

Version 8.24
Added ability to sort on month names and abbreviations.

Version 8.23
Added options for treating certain classes of characters as their "basic" counterparts.

Version 8.22
Memory usage has been significantly reduced.

Version 8.20
It is now possible to use the collation rules for a locale rather than writing
a sort order definition. This is done by giving a locale name as argument to the
-s flag. If the argument to the -s flag is the word "locale", the collation rules
for the current locale will be used.
