A new class QgsStringUtils has been added which allows PyQGIS scripts to utilise the new fuzzy matching algorithms added in 2.12. These include functions for finding the Levenshtein edit distance between two strings and for calculating the soundex phonetic representation of a string. These algorithms have been highly optimized for performance, so they are ready for you to start fuzzy matching across millions of strings!
