mechanism if compiled with FT_DEBUG_LEVEL_TRACE. See the file
|

`ftdebug.h' for more details.
|
||||
|
||||
- YAMATO Masatake contributed improved handling of MacOS resource
|
||||
forks on non-MacOS platforms (for example, Linux can mount MacOS
|
||||
file systems).
|
||||
|
||||
- The cache sub-system has been rewritten.
|
||||
|
||||
- There is now support for deinstallation of faces.
