  Security issue fixed:

  - CVE-2018-6942: Fixed a NULL pointer dereference within ttinerp.c
  (bsc#1079603).

  Non-security issues fixed:

  - Update to version 2.10.1

  * The bytecode hinting of OpenType variation fonts was flawed, since the
  data in the `CVAR' table wasn't correctly applied.

  * Auto-hinter support for Mongolian.

  * The handling of  the default character in PCF fonts as  introduced in
  version 2.10.0 was partially broken, causing premature abortion
  of charmap iteration for many fonts.

  * If  `FT_Set_Named_Instance' was  called  with  the same  arguments
  twice in a row, the function  returned an incorrect error code the
  second time.

  * Direct   rendering   using  FT_RASTER_FLAG_DIRECT   crashed   (bug
  introduced in version 2.10.0).

  * Increased  precision  while  computing  OpenType  font   variation
  instances.

  * The  flattening  algorithm of  cubic  Bezier  curves was  slightly
  changed to make  it faster.  This can cause  very subtle rendering
  changes, which aren't noticeable by the eye, however.

  * The  auto-hinter  now  disables hinting  if there  are blue  zones
  defined for a `style' (i.e., a certain combination of a script and its
  related typographic features) but the font doesn't contain any
  characters needed to set up at least one blue zone.

  - Add tarball signatures and freetype2.keyring

  - Update to version 2.10.0

  * A bunch of new functions has been added to access and process
  COLR/CPAL data of OpenType fonts with color-layered glyphs.

  * As a GSoC 2018 project, Nikhil Ramakrishnan completely
  overhauled and modernized the API reference.

  * The logic for computing the global ascender, descender, and height of
  OpenType fonts has been slightly adjusted for consistency.

  * `TT_Set_MM_Blend' could fail if called repeatedly with the same
  arguments.

  * The precision of handling deltas in Variation Fonts has been
  increased.The problem did only show up with multidimensional
  designspaces.

  * New function `FT_Library_SetLcdGeometry' to set up the geometry
  of LCD subpixels.

  * FreeType now uses the `defaultChar' property of PCF fonts to set the
  glyph for  the undefined  character  at glyph  index 0  (as FreeType
  already does for all other supported font formats).  As a consequence,
  the order of glyphs of a PCF font if accessed with  FreeType can be
  different now compared to previous versions. This change doesn't
  affect PCF font access with cmaps.

  * `FT_Select_Charmap' has been changed to allow  parameter value
  `FT_ENCODING_NONE' ...

  Description truncated. Please see the references for more information.");
