# Changelog 
- Cardinal and Decimal have randomized gender assignment
- Fraction has randomized gender assignment for integer portion
- Measure now has more fluent normalization of fractional amounts. (Note, due to Sparrowhawk architecture it can sound slightly awkward: 1 1/2  l-> "uno y medio litros" as opposed to more common "uno litro y medio"). Change would require rewriting of how measure verbalizer manages fraction tags.
- Non-deterministic strings now permit apocope for "una". This arises when the number precedes a noun with stressed "a" sound. Since this is hard to determine which FST setup, this is left to normalize_with_audio to manage.
