# Changes in FPV 14

This document covers the functional changes introduced in FPV 14 vs. 13.
These changes fall into two categories: 1) changes to existing behavior
2) new functionality.

## Changes to existing behavior

  * Changes inversion of max_descent to use values passed out from Skytype.  Original code
    inverted the value such that a negative value became positive. Change is in Skytype
    source and not in fontprocessor repo.
  * Changes return value of FontFile.glyphs to return only the Unicode values in the font.  Original code
    returned all entries in the font, sorted by glyph ID, and listed by Unicode value.  GlyphIDs which did
    not have Unicode mapping previously had an entry value of -1.
  * Replaces all calls into FontParser and FontForge with calls into Skytype.
