Overview of changes leading to 3.3.0
Monday, January 31, 2022

• Improved documentation. (Matthias Clasen)

• Internal code cleanup, using C++ standard library more. (Behdad Esfahbod)

• The low 16-bits of face index will be used by hb_face_create() to select a
  face inside a font collection file format, while the high 16-bits will be
  used by hb_font_create() to load the named instance. (Behdad Esfahbod)

• Glyph positions and other font metrics now apply synthetic slant set by
  hb_font_set_synthetic_slant(), for improved positioning for synthetically
  slanted fonts. (Behdad Esfahbod)

• Fixed unintentional locale dependency in hb_variation_to_string() for decimal
  point representation. (Matthias Clasen)

• When applying pair positioning (kerning) the positioning value is split
  between the two sides of the pair for improved cursor positioning between
  such pairs. (Behdad Esfahbod)

• Introduced new HB_GLYPH_FLAG_UNSAFE_TO_CONCAT, to be used in conjunction
  with HB_GLYPH_FLAG_UNSAFE_TO_BREAK for optimizing re-shaping during line
  breaking. Check the documentation for further details. (Behdad Esfahbod)

• Improved handling of macrolanguages when mapping BCP 47 codes to OpenType
  tags. (David Corbett)

  +HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
  +hb_segment_properties_overlay()
  +hb_buffer_create_similar()
  +hb_font_set_synthetic_slant()
  +hb_font_get_synthetic_slant()
