3.4.0
Perform sanity checks on shaping results is now part of “harfbuzz” library and can be enabled by setting the buffer flag HB_BUFFER_FLAG_VERIFY. (Behdad Esfahbod)
Arabic Mark Transient Reordering Algorithm have been updated to revision 6. (Khaled Hosny)
ISO 15924 code for mathematical notation, ‘Zmth’, now maps to the OpenType ‘math’ tag. (Alexis King)
It is now possible to get at once all math kerning values for a given glyph at a given corner. (Alexis King)
Fix locale_t portability issues on systems the typedef’s it to a void pointer. (Behdad Esfahbod)
New API:
+HB_BUFFER_FLAG_VERIFY
+HB_OT_TAG_MATH_SCRIPT
+HB_SCRIPT_MATH
+hb_ot_math_kern_entry_t
+hb_ot_math_get_glyph_kernings
Deprecated API

3.3.2
Revert splitting of pair positioning values introduced in 3.3.0 as it proved problematic. (Behdad Esfahbod)
3.3.1
Fix heap-use-after-free in harfbuzz-subset introduced in previous release. (Garret Rieger)
3.3.0
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)
New API:
+HB_GLYPH_FLAG_UNSAFE_TO_CONCAT
