   Upstream change announcement:

     I. IMPORTANT CHANGES

       - Support for OpenType Variation Fonts is now complete.   The last
         missing part was handling the `VVAR' and `MVAR' tables, which is
         available with this release.

       - A new  function `FT_Face_Properties' allows the  control of some
         module  and   library  properties  per  font.    Currently,  the
         following properties can be  handled: stem darkening, LCD filter
         weights, and the random seed for the `random' CFF operator.

       - The PCF change to show more `colourful' family names (introduced
         in version 2.7.1) was too radical; it can now be configured with
         PCF_CONFIG_OPTION_LONG_FAMILY_NAMES   at   compile   time.    If
         activated, it can  be switched off at run time  with the new pcf
         property  `no-long-family-names'.  If  the `FREETYPE_PROPERTIES'
         environment variable is available, you can say

           FREETYPE_PROPERTIES=pcf:no-long-family-names=1

       - Support  for  the  following  scripts  has  been  added  to  the
         auto-hinter.

           Adlam, Avestan, Bamum, Buhid, Carian, Chakma, Coptic, Cypriot,
           Deseret, Glagolitic, Gothic, Kayah, Lisu, N'Ko, Ol Chiki, Old
           Turkic, Osage, Osmanya, Saurashtra, Shavian, Sundanese, Tai
           Viet, Tifinagh, Unified Canadian Syllabics, Vai

     II. IMPORTANT BUG FIXES

       - `Light' auto-hinting  mode no  longer uses TrueType  metrics for
         TrueType  fonts.   This bug  was  introduced  in version  2.4.6,
         causing   horizontal  scaling   also.    Almost  all   GNU/Linux
         distributions (with Fedora as  a notable exception) disabled the
         corresponding patch for good reasons; chances are thus high that
         you won't notice a difference.

         If  optical backward  compatibility for  legacy applications  is
         necessary, you might enable the AF_CONFIG_OPTION_TT_SIZE_METRICS
         configuration option.   However, it  is strongly  recommended to
         avoid that, adjusting font sizes instead.

       - If a TrueType font gets loaded with FT_LOAD_NO_HINTING, FreeType
         now scales  the font linearly  again (bug introduced  in version
         2.4.6).

       - CVE-2017-8105,  CVE-2017-8287:  Older   FreeType  versions  have
         out-of-bounds  writes  caused  by  heap-based  buffer  overflows
         related to Type 1 fonts.

     III. MISCELLANEOUS

       - A  new function  `FT_Set_Default_Properties' has  been added  to
         parse    the    `FREETYPE_PROPERTIES'    environment    variable
         (previously, it  was internal only).   `FT_Init_FreeType' always
         call this  function, but  `FT_New_Library' does not  (similar to
         `FT_Add_Default_Modules').

       - To be in sync with OpenType version 1.7 and newer, macros

           FT_PARAM_TAG_IGNORE_PREFERRED_FAMILY,
           FT_PARAM_TAG_IGNORE_PREFERRED_SUBFAMILY,
           TT_NAME_ID_PREFERRED_FAMILY
           TT_NAME_ID_PREFERRED_SUBFAMILY

         are renamed to

           FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_FAMILY,
           FT_PARAM_TAG_IGNORE_TYPOGRAPHIC_SUBFAMILY,
           TT_NAME_ID_TYPOGRAPHIC_FAMILY
           TT_NAME_ID_TYPOGRAPHIC_SUBFAMILY

         The old macro names are deprecated (but still available).

       - Support for SFNT `name' tables has been improved.

         . Format  1 `name' tables  are now supported.  Use  new function
           `FT_Get_Sfnt_LangTag' to access associated language tags.

         . Language, encoding, and name IDs have been updated to OpenType
           version 1.8.1.

       - The new CFF  engine now handles the `random'  operator.  All CFF
         opcodes are now supported.

       - The CFF module  has a new property `random-seed'  to control the
         pseudo-random number generation for the `random' operator.

       - The `freetype-config' script is now a wrapper of `pkg-config' if
         this program is available in the path.

       - FT_LOAD_TARGET_LCD  is now  a  variant of  FT_LOAD_TARGET_LIGHT;
         this should provide better rendering results.

       - A mode to display  light auto-hinting with sub-pixel positioning
         has been added to `ftdiff'.
