Release 0.102

    Additionally, the functions operate on Unicode code points and not user visible characters (or grapheme clusters). Some languages combine multiple code points into a single user-perceived character, the basic unit of a writing system for a language, but the functions will treat each code point as a separate unit.

    All Regular Expression Functions have been rewritten to improve performance. The new versions are often twice as fast and in some cases can be many orders of magnitude faster (due to removal of quadratic behavior). This change introduced some minor incompatibilities that are explained in the documentation for the functions.
