Overview of changes leading to 2.0.0
Wednesday, October 17, 2018
====================================
- Added AAT shaping support (morx/kerx/trak).
Automatically used if GSUB/GPOS are not available respectively.
Set HB_OPTIONS=aat env var to have morx/kerx preferred over
GSUB/GPOS.
- Apply TrueType kern table internally, instead of relying on
hb_font_t callbacks.
- Khmer shaper significantly rewritten to better match Uniscribe.
- Indic3 tags ('dev3', etc) are passed to USE shaper.
- .dfont Mac font containers implemented.
- Script- and language-mapping revamped to better use BCP 47.
- Misc USE and Indic fixes.
- Misc everything fixes.
- Too many things to list. Biggest release since 0.9.1, with
over 500 commits in just over 5 weeks! Didn't intend it to
be a big release. Just happened to become.
- hb-ft now locks underlying FT_Face during use.
API changes:
- Newly-created hb_font_t's now have our internal "hb-ot-font"
callbacks set on them, so they should work out of the box
without any callbacks set. If callbacks are set, everything
is back to what it was before, the fallback callbacks are
null. If you to get the internal implementation modified,
sub_font it.
- New hb_font_funcs_set_nominal_glyphs_func() allows speeding
up character to glyph mapping.
New API:
+HB_FEATURE_GLOBAL_START
+HB_FEATURE_GLOBAL_END
+hb_buffer_set_invisible_glyph()
+hb_buffer_get_invisible_glyph()
+hb_font_funcs_set_nominal_glyphs_func()
+hb_ot_layout_table_select_script()
+hb_ot_layout_script_select_language()
+hb_ot_layout_feature_get_name_ids()
+hb_ot_layout_feature_get_characters()
+hb_name_id_t
+HB_NAME_ID_INVALID
+HB_OT_MAX_TAGS_PER_SCRIPT
+hb_ot_tags_from_script_and_language()
+hb_ot_tags_to_script_and_language()
Deprecated API:
-hb_font_funcs_set_glyph_func()
-hb_unicode_eastasian_width_func_t
-hb_unicode_funcs_set_eastasian_width_func()
-hb_unicode_eastasian_width()
-hb_unicode_decompose_compatibility_func_t
-HB_UNICODE_MAX_DECOMPOSITION_LEN
-hb_unicode_funcs_set_decompose_compatibility_func()
-hb_unicode_decompose_compatibility()
-hb_font_funcs_set_glyph_h_kerning_func()

-hb_font_get_glyph_h_kerning()
-hb_font_get_glyph_v_kerning()
-hb_font_get_glyph_kerning_for_direction()
-hb_ot_layout_table_choose_script()
-hb_ot_layout_script_find_language()
-hb_ot_tags_from_script()
-hb_ot_tag_from_language()
