[Douglas R. Reno]

New major version

[Bruce Dubbs]

Overview of changes leading to 11.0.0 - Monday, March 24, 2025

• There are three new font-functions implementations (integrations) in this release:
  • hb-coretext has gained one, calling into the CoreText library,
  • hb-directwrite has gained one, calling into the DirectWrite library.
  • hb-fontations has gained one, calling into the Skrifa Rust library. All three are mostly useful for performance and correctness testing, but some clients might find them useful. An API is added to use them from a single API by providing a backend name string:
  • hb_font_set_funcs_using()
• Several new APIs are added, to load a font-face using different "face-loaders", and a single entry point to them all using a loader name string:
  • hb_ft_face_create_from_file_or_fail() and hb_ft_face_create_from_blob_or_fail()
  • hb_coretext_face_create_from_file_or_fail() and hb_coretext_face_create_from_blob_or_fail()
  • hb_directwrite_face_create_from_file_or_fail() and hb_directwrite_face_create_from_blob_or_fail()
  • hb_face_create_from_file_or_fail_using()
• All drawing and painting operations using the default, hb-ot functions have become memory allocation-free.
• Several performance optimizations have been implemented.
• Application of the trak table during shaping has been improved.
• The directwrite shaper now supports font variations, and correctly applies user features.
• The hb-directwrite API and shaper has graduated from experimental.
• Various bug fixes and other improvements.

• New API:
  • +hb_malloc
  • +hb_calloc
  • +hb_realloc
  • +hb_free
  • +hb_face_list_loaders
  • +hb_face_create_or_fail_using
  • +hb_face_create_from_file_or_fail_using
  • +hb_font_list_funcs
  • +hb_font_set_funcs_using
  • +hb_coretext_face_create_from_blob_or_fail
  • +hb_directwrite_face_create_from_file_or_fail
  • +hb_directwrite_face_create_from_blob_or_fail
  • +hb_directwrite_font_create
  • +hb_directwrite_font_get_dw_font_face
  • +hb_directwrite_font_set_funcs
  • +hb_fontations_font_set_funcs
  • +hb_ft_face_create_from_blob_or_fail
  • +hb_paint_push_font_transform
  • +hb_paint_push_inverse_font_transform
  • +HB_BUFFER_CLUSTER_LEVEL_GRAPHEMES
  • +HB_BUFFER_CLUSTER_LEVEL_IS_MONOTONE
  • +HB_BUFFER_CLUSTER_LEVEL_IS_GRAPHEMES
  • +HB_BUFFER_CLUSTER_LEVEL_IS_CHARACTERS

• Deprecated API:
  • +hb_directwrite_font_get_dw_font
