Well, the 2.1.x "branch" was created to perform important internal 
changes to the
library, mostly to simplify the engine (by removing redundancies) and 
ease porting.

Unfortunately, this work is still not finished, even though there are 
source files
present in the current package that contain some improvements, these are 
never
compiled in normal builds since everything isn't ready yet.

For example, none of the following are currently compiled:

- "ftsysio.c" and "ftsysmem.c" should ultimately replace "ftsystem.c", 
while
  separating the i/o and memory management routines to two distinct files
- "ftobject.c" contains a small and generic object subsystem
- "fthash.c" contains a generic dynamic hash table implementation

there are also lots of other changes to perform, mainly in the definition of
internal "services" (i.e. module interfaces), what certain services are and
should do (e.g. it's possible to simplify most of the work perform by font
drivers to load glyph, but this requires a drastic semantic change), and a
few other things..


I can't say when these changes will be completed. In the mean-time, you can
still use your custom "ftsystem.c"
