PLT-Scheme 299.108 released
MzScheme and MrEd are now version 299.108 in the SVN repository trunk.
The changes are related to Unicode and SRFI-75:
* Changed `char-lower-case?’ and `char-upper-case?’ to match the
Unicode “Lowercase” and “Uppercase” properties, instead of SRFI-13.
* Added `string-upcase’, `string-downcase’, `string-titlecase’,
`string-foldcase’, and `char-foldcase’.
* \U in strings and characters allows up to 8 digits (again) instead
* In case-insensitive mode, symbols are case-folded instead
of downcased (usually the same thing, but not always).
