@ -67,6 +67,10 @@ LATEST CHANGES BETWEEN 2.1.8 and 2.1.7
forks on non-MacOS platforms (for example, Linux can mount MacOS
file systems).
- Support for MacOS has been improved; there is now a new function
`FT_New_Face_From_FSSpec' similar to `FT_New_Face' except that
it accepts an FSSpec instead of a path.
- The cache sub-system has been rewritten.
- There is now support for deinstallation of faces.
