Overview of changes leading to 1.0.6 Thursday, October 15, 2015 ==================================== - Reduce max nesting level in OT lookups from 8 to 6. Should not affect any real font as far as I know. - Fix memory access issue in ot-font. - Revert default load-flags of fonts created using hb_ft_font_create() back to FT_LOAD_DEFAULT|FT_LOAD_NO_HINTING. This was changed in last release (1.0.5), but caused major issues, so revert. harfbuzz/harfbuzz#143 Overview of changes leading to 1.0.5 Tuesday, October 13, 2015 ==================================== - Fix multiple memory access bugs discovered using libFuzzer. harfbuzz/harfbuzz#139 Everyone should upgrade to this version as soon as possible. We now have continuous fuzzing set up, to avoid issues like these creeping in again. - Misc fixes. - New API: * hb_font_set_parent(). * hb_ft_font_[sg]et_load_flags() The default flags for fonts created using hb_ft_font_create() has changed to default to FT_LOAD_DEFAULT now. Previously it was defaulting to FT_LOAD_DFEAULT|FT_LOAD_NO_HINTING. - API changes: * Fonts now default to units-per-EM as their scale, instead of 0. * hb_font_create_sub_font() does NOT make parent font immutable anymore. hb_font_make_immutable() does.
