WHAT'S NEW
Version 5.1:
Compatible with Mac OS X 10.7 Lion, and can also be used on Mac OS X 10.5 Leopard and 10.6 Snow Leopard. It is a 32-bit Universal (Intel & PowerPC) Carbon application for Mac OS X.
New and updated encodings and data files - FLS 5.1 ships with updated versions of the Unicode-to-glyphname mapping files (standard.nam and several others), updated vendors.dat, updated tags.txt, as well as a largely revamped set of standard encoding files. Included is a set of new "OpenType" encoding files ("OpenType Standard", "OpenType LatPro", "OpenType LatPro SC", "OpenType LatCyrGrk" etc.) which are suitable as a basis for designing OpenType fonts. Rather than the old "afii" naming scheme, all the encoding files use the new "uni" naming scheme.
Application speed - On Intel Macs, FLS 5.1 runs much faster than 5.0.4. For example, Action Sets run approx. 2.5 times faster in 5.1 than in 5.0.4, running on Mac OS 10.6.8.
Creating OpenType fonts with up to 65,535 glyphs - FontLab Studio 5.1 has no longer the 6,400 glyph limit. It allows you to open, save and generate fonts with up to 65,535 glyphs.
Improved OpenType Layout support through FEA 2.5 - The Adobe FDK for OpenType (AFDKO) version 2.5 library is integrated in 5.1 (as opposed to 1.6 in 5.0.4). This means that you can use FEA 2.5 syntax that supports mark attachment or "sub fi by f i" type of statements, as well as "script DFLT". Note: some changes may be required in your OpenType feature definition code to make them compile.
New Clean up paths feature - The "Clean up paths" algorithm from Fontographer is integrated. It's available through the Action / Action Set dialogs (in the Contour group of the dialogs as "CleanUp"). This algorithm is not MM-compatible, unlike "Optimize". For single-master fonts, however, it will deliver different, sometimes better, results, than "Optimize".
Improved Python integration - FLS 5.1 build 4311 integrates with the "current" version of Python, i.e. 2.5 on Mac OS X 10.5, 2.6 on 10.6, and 2.7 on 10.7, while PP1 integrated with Python 2.5, and FLS 5.0.4 integrated with Python 2.3.
Numerous bugfixes and improvements.
