## Version 9.01 (2011-02-07)

This is the second release in the stable 9.x series.

Highlights in this release include:

A new, robust CFF parser implemented in C (replacing the previous Poscript one),

tiffscaled device - this renders internally as tiffgray, but then downsamples by an integer scale factor (specified by -dDownScaleFactor=n) and error diffuses to 1bpp output. The tiffscaled device also implements limited minimum feature size functionality; by setting -dMinFeatureSize to 1, 2 or 3, the device output is guaranteed to generate minimum dot sizes as multiples of the final resolution, useful for devices that offer finer position control than dot size control.

Add DSC compatible output in ps2write.

Windows makefiles now support 64 bit builds on 64 bit systems.

A number of performance, memory use, and stability improvements with the new features introduced in 9.00, plus the usual bug fixes.

We have also dropped support for Watcom and Borland development environments. These had not been maintained for some time, and were suffering "bit rot".
