FreeType 2  is a software  font engine that  is designed to  be small,
efficient,  highly   customizable,  and  portable   while  capable  of
producing high-quality output (glyph images) of most vector and bitmap
font formats.

Note that  FreeType 2 is  a font service  and doesn't provide  APIs to
perform higher-level features, like text layout or graphics processing
(e.g.,  colored  text  rendering,  `hollowing',  etc.).   However,  it
greatly simplifies these tasks by providing a simple, easy to use, and
uniform interface to access the content of font files.

FreeType  2  is  released  under  two open-source  licenses:  our  own
BSD-like FreeType  License and the  GPL.  It can  thus be used  by any
kind of projects, be they proprietary or not.


CHANGES BETWEEN 2.4.10 and 2.4.11


    - Some vulnerabilities in the  BDF implementation have been fixed.
      Users of this font format should upgrade.


    - Subpixel  hinting support  has been  contributed by  Infinality,
      based on Greg Hitchcock's whitepaper at

      Originally, it was a separate patch available from

      and which has been integrated.

      Note that  ClearType support is not  completely implemented!  In
      particular,  full support  for the  options `compatible_widths',
      `symmetrical_smoothing,  and  `bgr'  (via the  GETINFO  bytecode
      instruction) is missing.

      Activation of  subpixel hinting  support can be  controlled with
      the `TT_CONFIG_OPTION_SUBPIXEL_HINTING' configuration option; it
      is switched off by default.  This feature is still experimental;
      we welcome test reports!

    - Support for OpenType collections (OTC) has been added.

    - Pure CFF fonts within an SFNT wrapper are now supported.


    - Minor rendering improvements to the auto-hinter.

    - `FT_GlyphSlot_Oblique' now uses a shear angle of 12°.

    - Experimental support  to handle `property modules',  for example
      to control the  behaviour of the auto-hinter.   The API consists
      of two new functions, `FT_Property_Set' and `FT_Property_Get'.

      The code is  still subject to change and should  not be used for

    - The `ftdiff' demo program now supports UTF-8 encoded input files
      for option `-f'.

    - Using keys `r' and `R', you can now adjust the stroker radius in
      the `ftview' demo program.

    - Other, minor fixes and improvements.
