- The native TrueType hinter contained some bugs which prevented

some fonts to be rendered correctly, most notably Legendum.otf.
|

|

- The PostScript hinter now produces much improved results.
|

|

- The linear advance width and height values were incorrectly
|
||||
rounded, making them virtually unusable if not loaded with
|
||||
FT_LOAD_LINEAR_DESIGN.
|
||||
|
||||
- Indexing CID-keyed CFF fonts is now working: The glyph index is
|
||||
correctly treated as a CID, similar to FreeType's CID driver
|
||||
module. Note that CID CMaps support is still missing.
