Overview of changes leading to 12.1.0 Wednesday, October 1, 2025 ===================================== - Build fixes with GCC 15 on some 32 bit platforms. - Fix misaligned pointer use. - New API, `hb_ot_layout_lookup_collect_glyph_alternates()`, to collect glyph substitutions from single and alternate substitution lookups in one call, instead of getting substitutions one by one using `hb_ot_layout_lookup_get_glyph_alternates()`. - New API +hb_ot_layout_lookup_collect_glyph_alternates() Overview of changes leading to 12.0.0 Sunday, September 28, 2025 ===================================== - The major feature of this release is that the Variable Composites / Components (`VARC` table) addition to the ISO OpenFontFormat has graduated from experimental, and is now enabled by default. It can be disabled at compile time by defining the `HB_NO_VAR_COMPOSITES`z macro. `VARC` table is a new way to store glyph outlines, that allows for better shape reuse, and can reduce font file size for Chinese, Japanese, Korean, and some other scripts drastically. Some font design tools provide a similar feature to designers, known as "smart components". This technology brings the same idea to the compiled font file. For the format specification, see: https://github.com/harfbuzz/boring-expansion-spec/blob/main/VARC.md Test fonts can be found at: https://github.com/notofonts/noto-cjk-varco/releases/tag/v0.003 The Fontra font editor already supports this technology. Note that this new format involves just the HarfBuzz draw API and does not affect shaping. - Correctly handle `markFilteringSet` lookup field during subsetting. - Deduplicate features during subsetting. - Disable “more” buffer messages that give more verbose output when using buffer messages callbacks, as it has a performance overhead. Users/tools that need the more verbose messages should define `HB_BUFFER_MESSAGE_MORE` to 1 when building HarfBuzz. - Shaping and instancing optimizations. - Fix subsetting issues when building with GCC 12. Overview of changes leading to 11.5.1 Monday, September 22, 2025 ===================================== - Optimized partial-instancing of fonts with a large number of axes. Now over two times faster. - Fix C++ STL atomics implementation.

Overview of changes leading to 11.4.3 Saturday, August 23, 2025 ==================================== - Make shaping fail much faster for certain malformed fonts (e.g., those that trigger infinite recursion). - Fix undefined behaviour introduced in 11.4.2. - Fix detection of the “Cambria Math” font when fonts are scaled, so the workaround for the bad `MATH` table constant is applied. Overview of changes leading to 11.4.2 Thursday, August 21, 2025 ==================================== - Various performance and memory usage improvements. - The `hb-shape` command line tool can now be built with the amalgamated `harfbuzz.cc` source. - Fix regression in handling version 2 of `avar` table. - Increase various buffer length limits for better handling of fonts that generate huge number of glyphs per codepoint (e.g. Noto Sans Duployan) - Improvements to the harfrust shaper for more accurate testing. Overview of changes leading to 11.4.1 Wednesday, August 13, 2025 ==================================== - Fix clang compiler warnings. Overview of changes leading to 11.4.0 Wednesday, August 13, 2025 ==================================== - General shaping and subsetting speedups. - Fix in Graphite shaping backend when glyph advances became negative. - Subsetting improvements, pruning empty mark-attachment lookups. - Don't use the macro name `_S`, which is reserved by system liberaries. - Build fixes and speedup. - Add a `kbts` shaping backend that calls into the `kb_text_shape` single-header shaping library. This is purely for testing and performance evaluation and we do NOT recommend using it for any other purposes. Overview of changes leading to 11.3.3 Sunday, July 26, 2025 ==================================== - Fix but in vertical shaping of fonts without the vmtx table. Overview of changes leading to 11.3.2 Sunday, July 20, 2025 ==================================== - Fix build with non-compliant C++11 compilers that don't recognize the "and" keyword. Overview of changes leading to 11.3.1 Sunday, July 20, 2025 ==================================== - Fix crasher in the glyph_v_origin function introduced in 11.3.0. Overview of changes leading to 11.3.0 Sunday, July 20, 2025 ==================================== - Speed up handling fonts with very large number of variations: - Drawing by up to 40%. - Calculating glyph extents by up to 15%. - Getting horizontal glyph advances by up to 45%. - Speed up getting horizontal and vertical glyph advances by up to 24%. - Significantly speed up vertical text shaping. - Various documentation improvements. - Various build improvements. - Various subsetting improvements. - Various improvements to Rust font functions (fontations integration) and shaper (HarfRust integration). - Rename harfruzz option and shaper to harfrust following upstream rename. - Implement hb_face_reference_blob() for DirectWrite font functions. - New API: +hb_font_get_glyph_origins_func_t +hb_font_get_glyph_h_origins_func_t +hb_font_get_glyph_v_origins_func_t +hb_font_funcs_set_glyph_h_origins_func() +hb_font_funcs_set_glyph_v_origins_func() +hb_font_get_glyph_h_origins() +hb_font_get_glyph_v_origins() Overview of changes leading to 11.2.1 Monday, May 12, 2025 ==================================== - Various build improvements. - Fix build with HB_NO_DRAW and HB_NO_PAINT - Add an optional “harfruzz” shaper that uses HarfRuzz; an ongoing Rust port of HarfBuzz shaping. This shaper is mainly used for testing the output of the Rust implementation. - Fix regression that caused applying unsafe_to_break() to the whole buffer to be ignored. - Update USE data files. - Fix getting advances of out-of-rage glyph indices in DirectWrite font functions. Overview of changes leading to 11.2.0 Monday, April 28, 2025 ==================================== - Painting of COLRv1 fonts without clip boxes is now about 10 times faster. - Synthetic bold/slant of a sub font is now respected, instead of using the parent’s. - Glyph extents for fonts synthetic bold/slant are now accurately calculated. - Various build fixes - New API: +hb_font_is_synthetic() +hb_font_draw_glyph_or_fail_func_t +hb_font_paint_glyph_or_fail_func_t +hb_font_funcs_set_draw_glyph_or_fail_func() +hb_font_funcs_set_paint_glyph_or_fail_func() +hb_font_draw_glyph_or_fail() +hb_font_paint_glyph_or_fail() - Deprecated API: -hb_font_draw_glyph_func_t -hb_font_paint_glyph_func_t -hb_font_funcs_set_draw_glyph_func() -hb_font_funcs_set_paint_glyph_func() Overview of changes leading to 11.1.0 Wednesday, April 16, 2025 ==================================== - Include bidi mirroring variants of the requested codepoints when subsetting. The new HB_SUBSET_FLAGS_NO_BIDI_CLOSURE can be used to disable this behaviour. - Various bug fixes. - Various build fixes and improvements. - Various test suite improvements. - New API: +HB_SUBSET_FLAGS_NO_BIDI_CLOSURE Overview of changes leading to 11.0.1 Friday, April 4, 2025 ==================================== - The change in version 10.3.0 to apply “trak” table tracking values to glyph advances directly has been reverted as it required every font functions implementation to handle it, which breaks existing custom font functions. Tracking is instead back to being applied during shaping. - When `directwrite` integration is enabled, we now link to `dwrite.dll` instead of dynamically loading it. - A new experimental APIs for getting raw “CFF” and “CFF2” CharStrings. - We now provide manpages for the various command line utilities. Building manpages requires “help2man” and will be skipped if it is not present. - The command line utilities now set different return value for different kinds of failures. Details are provided in the manpages. - Various fixes and improvements to `fontations` font functions. - All shaping operations using the `ot` shaper have become memory allocation-free. - Glyph extents returned by `hb-ot` and `hb-ft` font functions are now rounded in stead of flooring/ceiling them, which also matches what other font libraries do. - Fix “AAT” deleted glyph marks interfering with fallback mark positioning. - Glyph outlines emboldening have been moved out of `hb-ot` and `hb-ft` font functions to the HarfBuzz font layer, so that it works with any font functions implementation. - Fix our fallback C++11 atomics integration, which seems to not be widely used. - Various testing fixes and improvements. - Various subsetting fixes and improvements. - Various other fixes and improvements. 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() Overview of changes leading to 10.4.0 Saturday, March 1, 2025 ==================================== - Drawing glyphs using hb-draw API now avoids any “malloc” calls, which improves drawing performance by 10+%. - Add support new “GVAR” table fonts with more than 65535 glyphs. Support is currently behind a compilation flag and is disabled by default. - Some hb-directwrite and hb-ft APIs got renamed with more clear names and the old names are deprecated. - Various build and fuzzing fixes. - New API: +hb_directwrite_face_get_dw_font_face() +hb_ft_font_get_ft_face() - Deprecated API: -hb_directwrite_face_get_font_face() -hb_ft_font_get_face() Overview of changes leading to 10.3.0 Thursday, February 11, 2025 ==================================== - Vastly improved “AAT” shaping performance. LucidaGrande benchmark-shape before: 14.6ms after: 5.9ms. - Improved OpenType shaping performance (kerning / ligature), at the expense of ~1kb per face allocated cache memory. Roboto-Regular benchmark-shape before: 10.3ms after: 9.4ms. - Improved “COLRv1” benchmark-font paint performance. Before: 7.85ms after 4.85ms. - Don’t apply glyph substitutions in “morx” table of a font with known broken “morx” table (AALMAGHRIBI.ttf font). - Update IANA and OT language registries. - Various documentation updates. - Various build improvements, and test speed-ups. - The “hb_face_reference_blob()” API now works for faces created with “hb_face_create_for_tables()” if the face sets “get_table_tags” callback. This constructs a new face blob from individual table blobs. - Various fixes to how “trak” table is handled to bring it closer to Core Text behaviour. Particularly, the tracking values for sizes not explicitly set in the table are now properly interpolated, and the tracking is applied to glyph advances when they are returned by ot-font functions, instead of applying them during shaping. The “trak” pseudo OpenType feature that could be used to disable “trak” table application have been dropped. - Core Text font functions now support non-BMP code points. - The drawing algorithm used by hb-draw for “glyf” table now match the algorithm used by FreeType and Core Text. - The “hb_coretext_font_create()” API now copy font variations from Core Text font to the created HarfBuzz font. - Add an API to get the feature tags enabled on a given shape-plan after executing it, which can be used to applications to show in the UI what features are applied by default (which can vary based on the font, the script, the language, and the direction set on the buffer). - Add APIs to created HarfBuzz font from DirectWrite font, and copy the font variations. - New API: +hb_directwrite_font_create() +hb_directwrite_font_get_dw_font() +hb_ot_shape_plan_get_feature_tags() Overview of changes leading to 10.2.0 Saturday, January 11, 2025 ==================================== - Consider Unicode Variation Selectors when subsetting “cmap” table. - Guard hb_cairo_glyphs_from_buffer() against malformed UTF-8 strings. - Fix incorrect “COLR” v1 glyph scaling in hb-cairo. - Use locale-independent parsing of double numbers is “hb-subset” command line tool. - Fix incorrect zeroing of advance width of base glyphs in various “Courier New” font versions due to incorrect “GDEF” glyph classes. - Fix handling of long language codes with “HB_LEAN” configuration. - Update OpenType language system registry. - Allow all Myanmar tone marks (including visarga) in any order - Don’t insert U+25CC DOTTED CIRCLE before superscript/subscript digits - Handle Garay script as right to left script. - New API for serializing font tables and potentially repacking them in optimal way. This was a previously experimental-only API. - New API for converting font variation setting from and to strings. - Various build fixes - Various subsetter and instancer fixes. - New API: +hb_subset_serialize_link_t +hb_subset_serialize_object_t +hb_subset_serialize_or_fail() +hb_subset_axis_range_from_string() +hb_subset_axis_range_to_string() Overview of changes leading to 10.1.0 Tuesday, November 5, 2024 ==================================== - Fix the sign of fallback vertical glyph advance (used when font has no vertical advance data). - Increase maximum “CFF” operands limit 20 times to support more complex fonts. - Add “--face-loader” option to command line utilities. - Support “COLR” v0 table in hb_font_get_glyph_extents(). - Add support for font functions that use Core Text APIs, similar to FreeType font functions.

The plan can then be passed on to perform the subsetting operation. (Garret Rieger) - Draw API for extracting glyph shapes have been extended and finalized and is no longer an experimental API. The draw API supports glyf, CFF and CFF2 glyph outlines tables, and applies variation settings set on the font as well as synthetic slant. The new public API is not backward compatible with the previous, non-public, experimental API. (Behdad Esfahbod) - The hb-view tool will use HarfBuzz draw API to render the glyphs instead of cairo-ft when compiled with Cairo 1.17.5 or newer, setting HB_DRAW environment variable to 1 or 0 will force using or not use the draw API, respectively. (Behdad Esfahbod) - The hb-shape and hb-view tools now default to using HarfBuzz’s own font loading functions (ot) instead of FreeType ones (ft). They also have a new option, --font-slant, to apply synthetic slant to the font. (Behdad Esfahbod) - HarfBuzz now supports more than 65535 (the OpenType limit) glyph shapes and metrics. See https://github.com/be-fonts/boring-expansion-spec/issues/6 and https://github.com/be-fonts/boring-expansion-spec/issues/7 for details.

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_funcs_set_glyph_v_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() Overview of changes leading to 1.9.0 Monday, September 10, 2018 ==================================== - Added 'cmap' API to hb_face_t. - Face-builder API. - hb-ot-font re-creation should be much leaner now, as the font tables it uses are cached on hb_face_t now. - Internal source header file name changes: hb-*-private.hh is renamed to hb-*.hh. - New API: +HB_UNICODE_MAX +hb_face_collect_unicodes() +hb_face_collect_variation_selectors() +hb_face_collect_variation_unicodes() +hb_face_builder_create() +hb_face_builder_add_table() Overview of changes leading to 1.8.8 Tuesday, August 14, 2018 ==================================== - Fix hb-icu crash on architectures where compare_exchange_weak() can fail falsely. This bug was introduced in 1.8.4. https://bugs.chromium.org/p/chromium/issues/detail?id=873568 - More internal refactoring of atomic operations and singletons. - API changes: The following functions do NOT reference their return value before returning: * hb_unicode_funcs_get_default() * hb_glib_get_unicode_funcs() * hb_icu_get_unicode_funcs() This is consistent with their naming ("get", instead of "reference") as well as how they are used in the wild (ie. no one calls destroy() on their return value.) Overview of changes leading to 1.8.7 Wednesday, August 8, 2018 ==================================== - Fix assertion failure with GDEF-blacklisted fonts. Overview of changes leading to 1.8.6 Tuesday, August 7, 2018 ==================================== - Internal code shuffling. - New API to speed up getting advance widths for implementations that have heavy overhead in get_h_advance callback: +hb_font_funcs_set_glyph_h_advances_func +hb_font_funcs_set_glyph_v_advances_func +hb_font_get_glyph_advances_for_direction +hb_font_get_glyph_h_advances +hb_font_get_glyph_h_advances_func_t +hb_font_get_glyph_v_advances +hb_font_get_glyph_v_advances_func_t Overview of changes leading to 1.8.5 Wednesday, August 1, 2018 ==================================== - Major Khmer shaper improvements to better match Microsoft. - Indic bug fixes. - Internal improvements to atomic operations.

All of hb-subset.h is experimental right now and API WILL change. - New API: +hb_blob_copy_writable_or_fail() +HB_OT_TAG_BASE +hb_set_previous() +hb_set_previous_range() Overview of changes leading to 1.7.5 Tuesday, January 30, 2018 ==================================== - Separate Khmer shaper from Indic. - First stab at AAT morx. Not hooked up. - Misc bug fixes. Overview of changes leading to 1.7.4 Wednesday, December 20, 2017 ==================================== - Fix collect_glyphs() regression caused by hb_set_t changes. Overview of changes leading to 1.7.3 Monday, December 18, 2017 ==================================== - hb_set_t performance tuning and optimizations. - Speed up collect_glyphs() and reject garbage data. - In hb_coretext_font_create() set font point-size (ptem). - Misc fixes. Overview of changes leading to 1.7.2 Monday, December 4, 2017 ==================================== - Optimize hb_set_add_range(). - Misc fixes. - New API: +hb_coretext_font_create() Overview of changes leading to 1.7.1 Tuesday, November 14, 2017 ==================================== - Fix atexit object destruction regression. - Fix minor integer-overflow. Overview of changes leading to 1.7.0 Monday, November 13, 2017 ==================================== - Minor Indic fixes. - Implement kerning and glyph names in hb-ot-font. - Various DSO optimization re .data and .bss sizes. - Make C++11 optional; build fixes. - Mark all other backends "unsafe-to-break". - Graphite fix. Overview of changes leading to 1.6.3 Thursday, October 26th, 2017 ==================================== - Fix hb_set_t some more. Should be solid now. - Implement get_glyph_name() for hb-ot-font. - Misc fixes. Overview of changes leading to 1.6.2 Monday, October 23nd, 2017 ==================================== - Yesterday's release had a bad crasher; don't use it. That's what happens when one works on Sunday... https://github.com/harfbuzz/harfbuzz/issues/578 - Build fixes for FreeBSD and Chrome Android. Overview of changes leading to 1.6.1 Sunday, October 22nd, 2017 ==================================== - Don't skip over COMBINING GRAPHEME JOINER when ligating, etc. To be refined: https://github.com/harfbuzz/harfbuzz/issues/554 - Faster hb_set_t implementation. - Don't use deprecated ICU API. - Fix undefined-behavior in Myanmar shaper, introduced in 1.6.0 - Deprecated API: -hb_set_invert() Overview of changes leading to 1.6.0 Friday, October the 13th, 2017 ==================================== - Update to Unicode 10. - Various Indic and Universal Shaping Engine fixes as a result of HarfBuzz Hackfest with Jonathan Kew at Web Engines Hackfest at the Igalia offices in A Coruña, Spain. Thanks Igalia for having us! - Implement Unicode Arabic Mark Ordering Algorithm UTR#53. - Implement optical sizing / tracking in CoreText backend, using new API hb_font_set_ptem(). - Allow notifying hb_font_t that underlying FT_Face changed sizing, using new API hb_ft_font_changed(). - More Graphite backend RTL fixes. - Fix caching of variable font shaping plans. - hb-view / hb-shape now accept following new arguments: o --unicodes: takes a list of hex numbers that represent Unicode codepoints. - New API: +hb_face_get_table_tags() +hb_font_set_ptem() +hb_font_get_ptem() +hb_ft_font_changed() Overview of changes leading to 1.5.1 Tuesday, September 5, 2017 ==================================== - Fix "unsafe-to-break" in fallback shaping and other corner cases. All our tests pass with --verify now, meaning unsafe-to-break API works as expected. - Add --unicodes to hb-view / hb-shape. - [indic] Treat Consonant_With_Stacker as consonant. This will need further tweaking. - hb_buffer_diff() tweaks. Overview of changes leading to 1.5.0 Wednesday, August 23, 2017 ==================================== - Misc new API, for appending a buffer to another, and for comparing contents of two buffers for types of differences. - New "unsafe-to-break" API. Can be used to speed up reshaping in line-breaking situations. Essentially, after shaping, it returns positions in the input string (some of the cluster boundaries) that are "safe to break" in that if the text is segmented at that position and two sides reshaped and concatenated, the shaping result is exactly the same as shaping the text in one piece. hb-view and hb-shape and hb-shape now take --verify, which verifies the above property. Some corner cases of the implementation are still not quite working. Those will be fixed in subsequent releases. - New API: +hb_buffer_append() +hb_glyph_flags_t +HB_GLYPH_FLAG_UNSAFE_TO_BREAK +HB_GLYPH_FLAG_DEFINED +hb_glyph_info_get_glyph_flags() +HB_BUFFER_SERIALIZE_FLAG_GLYPH_FLAGS +hb_buffer_diff_flags_t +HB_BUFFER_DIFF_FLAG_EQUAL +HB_BUFFER_DIFF_FLAG_CONTENT_TYPE_MISMATCH +HB_BUFFER_DIFF_FLAG_LENGTH_MISMATCH +HB_BUFFER_DIFF_FLAG_NOTDEF_PRESENT +HB_BUFFER_DIFF_FLAG_DOTTED_CIRCLE_PRESENT +HB_BUFFER_DIFF_FLAG_CODEPOINT_MISMATCH +HB_BUFFER_DIFF_FLAG_CLUSTER_MISMATCH +HB_BUFFER_DIFF_FLAG_GLYPH_FLAGS_MISMATCH +HB_BUFFER_DIFF_FLAG_POSITION_MISMATCH +hb_buffer_diff Overview of changes leading to 1.4.8 Tuesday, August 8, 2017 ==================================== - Major fix to avar table handling. - Rename hb-shape --show-message to --trace. - Build fixes. Overview of changes leading to 1.4.7 Tuesday, July 18, 2017 ==================================== - Multiple Indic, Tibetan, and Cham fixes. - CoreText: Allow disabling kerning. - Adjust Arabic feature order again. - Misc build fixes. Overview of changes leading to 1.4.6 Sunday, April 23, 2017 ==================================== - Graphite2: Fix RTL positioning issue. - Backlist GDEF of more versions of Padauk and Tahoma. - New, experimental, cmake alternative build system. Overview of changes leading to 1.4.5 Friday, March 10, 2017 ==================================== - Revert "Fix Context lookup application when moving back after a glyph..." This introduced memory access problems. To be fixed properly soon. Overview of changes leading to 1.4.4 Sunday, March 5, 2017 ==================================== - Fix Context lookup application when moving back after a glyph deletion. - Fix buffer-overrun in Bengali. Overview of changes leading to 1.4.3 Saturday, February 25, 2017 ==================================== - Route Adlam script to Arabic shaper. - Misc fixes. - New API: +hb_font_set_face() - Deprecate API: -hb_graphite2_font_get_gr_font() Overview of changes leading to 1.4.2 Monday, January 23, 2017 ==================================== - Implement OpenType Font Variation tables avar/fvar/HVAR/VVAR. - hb-shape and hb-view now accept --variations. - New API: +hb_variation_t +hb_variation_from_string() +hb_variation_to_string() +hb_font_set_variations() +hb_font_set_var_coords_design() +hb_font_get_var_coords_normalized() +hb-ot-var.h: +hb_ot_var_axis_t +hb_ot_var_has_data() +hb_ot_var_get_axis_count() +hb_ot_var_get_axes() +hb_ot_var_find_axis() +hb_ot_var_normalize_variations() +hb_ot_var_normalize_coords() - MVAR to be implemented later. Access to named instances to be implemented later as well. - Misc fixes. Overview of changes leading to 1.4.1 Thursday, January 5, 2017 ==================================== - Always build and use UCDN for Unicode data by default. Reduces dependence on version of Unicode data in glib, specially in the Windows bundles we are shipping, which have very old glib. Overview of changes leading to 1.4.0 Thursday, January 5, 2017 ==================================== - Merged "OpenType GX" branch which adds core of support for OpenType 1.8 Font Variations. To that extent, the relevant new API is: - New API: +hb_font_set_var_coords_normalized() with supporting API: - New API: +HB_OT_LAYOUT_NO_VARIATIONS_INDEX +hb_ot_layout_table_find_feature_variations() +hb_ot_layout_feature_with_variations_get_lookups() +hb_shape_plan_create2() +hb_shape_plan_create_cached2() Currently variations in GSUB/GPOS/GDEF are fully supported, and no other tables are supported. In particular, fvar/avar are NOT supported, hence the hb_font_set_var_coords_normalized() taking normalized coordinates. API to take design coordinates will be added in the future. HVAR/VVAR/MVAR support will also be added to hb-ot-font in the future. - Fix regression in GDEF glyph class processing. - Add decompositions for Chakma, Limbu, and Balinese in USE shaper. - Misc fixes. Overview of changes leading to 1.3.4 Monday, December 5, 2016 ==================================== - Fix vertical glyph origin in hb-ot-font. - Implement CBDT/CBLC color font glyph extents in hb-ot-font. Overview of changes leading to 1.3.3 Wednesday, September 28, 2016 ==================================== - Implement parsing of OpenType MATH table. - New API: +HB_OT_TAG_MATH +HB_OT_MATH_SCRIPT +hb_ot_math_constant_t +hb_ot_math_kern_t +hb_ot_math_glyph_variant_t +hb_ot_math_glyph_part_flags_t +hb_ot_math_glyph_part_t +hb_ot_math_has_data() +hb_ot_math_get_constant() +hb_ot_math_get_glyph_italics_correction() +hb_ot_math_get_glyph_top_accent_attachment() +hb_ot_math_get_glyph_kerning() +hb_ot_math_is_glyph_extended_shape() +hb_ot_math_get_glyph_variants() +hb_ot_math_get_min_connector_overlap() +hb_ot_math_get_glyph_assembly() Overview of changes leading to 1.3.2 Wednesday, September 27, 2016 ==================================== - Fix build of hb-coretext on older OS X versions. Overview of changes leading to 1.3.1 Wednesday, September 7, 2016 ==================================== - Blacklist bad GDEF of more fonts (Padauk). - More CoreText backend crash fixes with OS X 10.9.5. - Misc fixes. Overview of changes leading to 1.3.0 Thursday, July 21, 2016 ==================================== - Update to Unicode 9.0.0 - Move Javanese from Indic shaper to Universal Shaping Engine. - Allow MultipleSubst to delete a glyph (matching Windows engine). - Update Universal Shaping Engine to latest draft from Microsoft. - DirectWrite backend improvements. Note: this backend is for testing ONLY. - CoreText backend improvements with unreachable fonts. - Implement symbol fonts (cmap 3.0.0) in hb-ft and hb-ot-font. - Blacklist bad GDEF of more fonts (Tahoma & others). - Misc fixes. Overview of changes leading to 1.2.7 Monday, May 2, 2016 ==================================== - Blacklist another version of Times New Roman (Bold) Italic from Windows 7. - Fix Mongolian Free Variation Selectors shaping with certain fonts. - Fix Tibetan shorthand contractions shaping. - Improved list of language tag mappings. - Unbreak build on Windows CE. - Make 'glyf' table loading lazy in hb-ot-font. Overview of changes leading to 1.2.6 Friday, April 8, 2016 ==================================== - Blacklist GDEF table of another set of Times New Roman (Bold) Italic. - DirectWrite backend improvements. Note: DirectWrite backend is exclusively for our internal testing and should NOT be used in any production system whatsoever. Overview of changes leading to 1.2.5 Monday, April 4, 2016 ==================================== - Fix GDEF mark-filtering-set, which was broken in 1.2.3. Overview of changes leading to 1.2.4 Thursday, March 17, 2016 ==================================== - Synthesize GDEF glyph class for any glyph that does not have one in GDEF. I really hope we don't discover broken fonts that shape badly with this change. - Misc build and other minor fixes. - API changes: - Added HB_NDEBUG. It's fine for production systems to define this to disable high-overhead debugging checks. However, I also reduced the overhead of those checks, so it's a non-issue right now. You can forget it. Just not defining anything at all is fine. Overview of changes leading to 1.2.3 Thursday, February 25, 2016 ==================================== - Blacklist GDEF table of certain versions of Times New Roman (Bold) Italic, due to bug in glyph class of ASCII double-quote character. This should address "regression" introduced in 1.2.0 when we switched mark zeroing in most shapers from BY_UNICODE_LATE to BY_GDEF_LATE. This fourth release in a week should finally stabilize things... - hb-ot-font's get_glyph() implementation saw some optimizations. Though, might be really hard to measure in real-world situations. - Also, two rather small API changes: We now disable some time-consuming internal bookkeeping if built with NDEBUG defined. This is a first time that we use NDEBUG to disable debug code. If there exist production systems that do NOT want to enable NDEBUG, please let me know and I'll add HB_NDEBUG. Added get_nominal_glyph() and get_variation_glyph() instead of get_glyph() - New API: +hb_font_get_nominal_glyph_func_t +hb_font_get_variation_glyph_func_t +hb_font_funcs_set_nominal_glyph_func() +hb_font_funcs_set_variation_glyph_func() +hb_font_get_nominal_glyph() +hb_font_get_variation_glyph() - Deprecated API: -hb_font_get_glyph_func_t -hb_font_funcs_set_glyph_func() Clients that implement their own font-funcs are encouraged to replace their get_glyph() implementation with a get_nominal_glyph() and get_variation_glyph() pair. The variation version can assume that variation_selector argument is not zero. Old (deprecated) functions will continue working indefinitely using internal gymnastics; it is just more efficient to use the new functions. Overview of changes leading to 1.2.2 Wednesday, February 24, 2016 ==================================== - Fix regression with mark positioning with fonts that have non-zero mark advances. This was introduced in 1.2.0 while trying to make mark and cursive attachments to work together. I have partially reverted that, so this version is much more like what we had before. All clients who updated to 1.2.0 should update to this version. Overview of changes leading to 1.2.1 Tuesday, February 23, 2016 ==================================== - CoreText: Fix bug with wrong scale if font scale was changed later. https://github.com/libass/libass/issues/212 - CoreText: Drastically speed up font initialization. - CoreText: Fix tiny leak. - Group ZWJ/ZWNJ with previous syllable under cluster-level=0. https://github.com/harfbuzz/harfbuzz/issues/217 - Add test/shaping/README.md about how to add tests to the suite. Overview of changes leading to 1.2.0 Friday, February 19, 2016 ==================================== - Fix various issues (hangs mostly) in case of memory allocation failure. - Change mark zeroing types of most shapers from BY_UNICODE_LATE to BY_GDEF_LATE. This seems to be what Uniscribe does. - Change mark zeroing of USE shaper from NONE to BY_GDEF_EARLY. That's what Windows does. - Allow GPOS cursive connection on marks, and fix the interaction with mark attachment. This work resulted in some changes to how mark attachments work. See: https://github.com/harfbuzz/harfbuzz/issues/211 https://github.com/harfbuzz/harfbuzz/commit/86c68c7a2c971efe8e35b1f1bd99401dc8b688d2 - Graphite2 shaper: improved negative advance handling (eg. Nastaliq). - Add nmake-based build system for Windows. - Minor speedup. - Misc. improvements. Overview of changes leading to 1.1.3 Monday, January 11, 2016 ==================================== - Ported Indic shaper to Unicode 8.0 data. - Universal Shaping Engine fixes. - Speed up CoreText shaper when font fallback happens in CoreText. - Documentation improvements, thanks to Khaled Hosny. - Very rough directwrite shaper for testing, thanks to Ebrahim Byagowi. - Misc bug fixes. - New API: * Font extents: hb_font_extents_t hb_font_get_font_extents_func_t hb_font_get_font_h_extents_func_t hb_font_get_font_v_extents_func_t hb_font_funcs_set_font_h_extents_func hb_font_funcs_set_font_v_extents_func hb_font_get_h_extents hb_font_get_v_extents hb_font_get_extents_for_direction * Buffer message (aka debug): hb_buffer_message_func_t hb_buffer_set_message_func() Actual message protocol to be fleshed out later. Overview of changes leading to 1.1.2 Wednesday, November 26, 2015 ==================================== - Fix badly-broken fallback shaper that affected terminology. https://github.com/harfbuzz/harfbuzz/issues/187 - Fix y_scaling in Graphite shaper. - API changes: * An unset glyph_h_origin() function in font-funcs now (sensibly) implies horizontal origin at 0,0. Ie, the nil callback returns true instead of false. As such, implementations that have a glyph_h_origin() that simply returns true, can remove that function with HarfBuzz >= 1.1.2. This results in a tiny speedup. Overview of changes leading to 1.1.1 Wednesday, November 24, 2015 ==================================== - Build fixes, specially for hb-coretext. Overview of changes leading to 1.1.0 Wednesday, November 18, 2015 ==================================== - Implement 'stch' stretch feature for Syriac Abbreviation Mark. https://github.com/harfbuzz/harfbuzz/issues/141 - Disable use of decompose_compatibility() callback. - Implement "shaping" of various Unicode space characters, even if the font does not support them. https://github.com/harfbuzz/harfbuzz/issues/153 - If font does not support U+2011 NO-BREAK HYPHEN, fallback to U+2010 HYPHEN. - Changes resulting from libFuzzer continuous fuzzing: * Reject font tables that need more than 8 edits, * Bound buffer growth during shaping to 32x, * Fix assertions and other issues at OOM / buffer max-growth. - Misc fixes and optimizations. - API changes: * All fonts created with hb_font_create() now inherit from (ie. have parent) hb_font_get_empty(). 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. https://github.com/harfbuzz/harfbuzz/issues/143 Overview of changes leading to 1.0.5 Tuesday, October 13, 2015 ==================================== - Fix multiple memory access bugs discovered using libFuzzer. https://github.com/harfbuzz/harfbuzz/issues/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. Overview of changes leading to 1.0.4 Wednesday, September 30, 2015 ==================================== - Fix minor out-of-bounds read error. Overview of changes leading to 1.0.3 Tuesday, September 1, 2015 ==================================== - Start of user documentation, from Simon Cozens! - Implement glyph_extents() for TrueType fonts in hb-ot-font. - Improve GPOS cursive attachments with conflicting lookups. - More fixes for cluster-level = 1. - Uniscribe positioning fix. Overview of changes leading to 1.0.2 Wednesday, August 19, 2015 ==================================== - Fix shaping with cluster-level > 0. - Fix Uniscribe backend font-size scaling. - Declare dependencies in harfbuzz.pc. FreeType is not declared though, to avoid bugs in pkg-config 0.26 with recursive dependencies. - Slightly improved debug infrastructure. More to come later. - Misc build fixes. Overview of changes leading to 1.0.1 Monday, July 27, 2015 ==================================== - Fix out-of-bounds access in USE shaper. Overview of changes leading to 1.0.0 Sunday, July 26, 2015 ==================================== - Implement Universal Shaping Engine: https://www.microsoft.com/typography/OpenTypeDev/USE/intro.htm http://blogs.windows.com/bloggingwindows/2015/02/23/windows-shapes-the-worlds-languages/ - Bump version to 1.0.0. The soname was NOT bumped.

Overview of changes leading to 0.9.39 Wednesday, March 4, 2015 ===================================== - Critical hb-coretext fixes. - Optimizations and refactoring; no functional change expected. - Misc build fixes. Overview of changes leading to 0.9.38 Friday, January 23, 2015 ===================================== - Fix minor out-of-bounds access in Indic shaper. - Change New Tai Lue shaping engine from South-East Asian to default, reflecting change in Unicode encoding model. - Add hb-shape --font-size. Can take up to two numbers for separate x / y size. - Fix CoreText and FreeType scale issues with negative scales. - Reject blobs larger than 2GB. This might break some icu-le-hb clients that need security fixes. See: http://www.icu-project.org/trac/ticket/11450 - Avoid accessing font tables during face destruction, in casce rogue clients released face data already. - Fix up gobject-introspection a bit. Python bindings kinda working. See README.python. - Misc fixes. - API additions: hb_ft_face_create_referenced() hb_ft_font_create_referenced() Overview of changes leading to 0.9.37 Wednesday, December 17, 2014 ===================================== - Fix out-of-bounds access in Context lookup format 3. - Indic: Allow ZWJ/ZWNJ before syllable modifiers. Overview of changes leading to 0.9.36 Thursday, November 20, 2014 ===================================== - First time that three months went by without a release since 0.9.2 was released on August 10, 2012! - Fix performance bug in hb_ot_collect_glyphs(): https://bugzilla.mozilla.org/show_bug.cgi?id=1090869 - Add basic vertical-text support to hb-ot-font. - Misc build fixes. Overview of changes leading to 0.9.35 Saturday, August 13, 2014 ===================================== - Fix major shape-plan caching bug when more than one shaper were provided to hb_shape_full() (as exercised by XeTeX). http://www.mail-archive.com/debian-bugs-dist@lists.debian.org/msg1246370.html - Fix Arabic fallback shaping regression. This was broken in 0.9.32. - Major hb-coretext fixes. That backend is complete now, including respecing buffer direction and language, down to vertical writing. - Build fixes for Windows CE. Should build fine now. - Misc fixes: Use atexit() only if it's safe to call from shared library https://bugs.freedesktop.org/show_bug.cgi?id=82246 Mandaic had errors in its Unicode Joining_Type https://bugs.freedesktop.org/show_bug.cgi?id=82306 - API changes: * hb_buffer_clear_contents() does not reset buffer flags now. After 763e5466c0a03a7c27020e1e2598e488612529a7, one doesn't need to set flags for different pieces of text. The flags now are something the client sets up once, depending on how it actually uses the buffer. As such, don't clear it in clear_contents(). I don't expect any changes to be needed to any existing client. Overview of changes leading to 0.9.34 Saturday, August 2, 2014 ===================================== - hb_feature_from_string() now accepts CSS font-feature-settings format. - As a result, hb-shape / hb-view --features also accept CSS-style strings. Eg, "'liga' off" is accepted now. - Add old-spec Myanmar shaper: https://bugs.freedesktop.org/show_bug.cgi?id=81775 - Don't apply 'calt' in Hangul shaper. - Fix mark advance zeroing for Hebrew shaper: https://bugs.freedesktop.org/show_bug.cgi?id=76767 - Implement Windows-1256 custom Arabic shaping. Only built on Windows, and requires help from get_glyph(). Used by Firefox. https://bugzilla.mozilla.org/show_bug.cgi?id=1045139 - Disable 'liga' in vertical text. - Build fixes. - API changes: * Make HB_BUFFER_FLAG_BOT/EOT easier to use. Previously, we expected users to provide BOT/EOT flags when the text *segment* was at paragraph boundaries. This meant that for clients that provide full paragraph to HarfBuzz (eg. Pango), they had code like this: hb_buffer_set_flags (hb_buffer, (item_offset == 0 ? HB_BUFFER_FLAG_BOT : 0) | (item_offset + item_length == paragraph_length ? HB_BUFFER_FLAG_EOT : 0)); hb_buffer_add_utf8 (hb_buffer, paragraph_text, paragraph_length, item_offset, item_length); After this change such clients can simply say: hb_buffer_set_flags (hb_buffer, HB_BUFFER_FLAG_BOT | HB_BUFFER_FLAG_EOT); hb_buffer_add_utf8 (hb_buffer, paragraph_text, paragraph_length, item_offset, item_length); Ie, HarfBuzz itself checks whether the segment is at the beginning/end of the paragraph. Clients that only pass item-at-a-time to HarfBuzz continue not setting any flags whatsoever. Another way to put it is: if there's pre-context text in the buffer, HarfBuzz ignores the BOT flag. If there's post-context, it ignores EOT flag. Overview of changes leading to 0.9.33 Tuesday, July 22, 2014 ===================================== - Turn off ARabic 'cswh' feature that was accidentally turned on. - Add HB_TAG_MAX_SIGNED. - Make hb_face_make_immutable() really make face immutable! - Windows build fixes. Overview of changes leading to 0.9.32 Thursday, July 17, 2014 ===================================== - Apply Arabic shaping features in spec order exactly. - Another fix for Mongolian free variation selectors. - For non-Arabic scripts in Arabic shaper apply 'rlig' and 'calt' together. - Minor adjustment to U+FFFD logic. - Fix hb-coretext build. Overview of changes leading to 0.9.31 Wednesday, July 16, 2014 ===================================== - Only accept valid UTF-8/16/32; we missed many cases before. - Better shaping of invalid UTF-8/16/32. Falls back to U+FFFD REPLACEMENT CHARACTER now. - With all changes in this release, the buffer will contain fully valid Unicode after hb_buffer_add_utf8/16/32 no matter how broken the input is. This can be overridden though. See below. - Fix Mongolian Variation Selectors for fonts without GDEF. - Fix minor invalid buffer access. - Accept zh-Hant and zh-Hans language tags. hb_ot_tag_to_language() now uses these instead of private tags. - Build fixes. - New API: * hb_buffer_add_codepoints(). This does what hb_buffer_add_utf32() used to do, ie. no validity check on the input at all. add_utf32 now replaces invalid Unicode codepoints with the replacement character (see below). * hb_buffer_set_replacement_codepoint() * hb_buffer_get_replacement_codepoint() Previously, in hb_buffer_add_utf8 and hb_buffer_add_utf16, when we detected broken input, we replaced that with (hb_codepoint_t)-1. This has changed to use U+FFFD now, but can be changed using these new API. Overview of changes leading to 0.9.30 Wednesday, July 9, 2014 ===================================== - Update to Unicode 7.0.0: * New scripts Manichaean and Psalter Pahlavi are shaped using Arabic shaper. * All the other new scripts to through the generic shaper for now. - Minor Indic improvements. - Fix graphite2 backend cluster mapping [crasher!] - API changes: * New HB_SCRIPT_* values for Unicode 7.0 scripts. * New function hb_ot_layout_language_get_required_feature(). - Build fixes.

Overview of changes leading to 0.9.28 Monday, April 28, 2014 ===================================== - Unbreak old-spec Indic shaping. (bug 76705) - Fix shaping of U+17DD and U+0FC6. - Add HB_NO_MERGE_CLUSTERS build option. NOT to be enabled by default for shipping libraries. It's an option for further experimentation right now. When we are sure how to do it properly, we will add public run-time API for the functionality. - Build fixes. Overview of changes leading to 0.9.27 Tuesday, March 18, 2014 ===================================== - Don't use "register" storage class specifier - Wrap definition of free_langs() with HAVE_ATEXIT - Add coretext_aat shaper and hb_coretext_face_create() constructor - If HAVE_ICU_BUILTIN is defined, use hb-icu Unicode callbacks - Add Myanmar test case from OpenType Myanmar spec - Only do fallback Hebrew composition if no GPOS 'mark' available - Allow bootstrapping without gtk-doc - Use AM_MISSING_PROG for ragel and git - Typo in ucdn's Makefile.am - Improve MemoryBarrier() implementation Overview of changes leading to 0.9.26 Thursday, January 30, 2014 ===================================== - Misc fixes. - Fix application of 'rtlm' feature. - Automatically apply frac/numr/dnom around U+2044 FRACTION SLASH. - New header: hb-ot-shape.h - Uniscribe: fix scratch-buffer accounting. - Reorder Tai Tham SAKOT to after tone-marks. - Add Hangul shaper. - New files: hb-ot-shape-complex-hangul.cc hb-ot-shape-complex-hebrew.cc hb-ot-shape-complex-tibetan.cc - Disable 'cswh' feature in Arabic shaper. - Coretext: better handle surrogate pairs. - Add HB_TAG_MAX and _HB_SCRIPT_MAX_VALUE.

Distros can enable ICU now without every application on earth getting linked to via libharfbuzz.so. For distros I recommend that they make sure they are building --with-glib --with-freetype --with-cairo, --with-icu, and optionally --with-graphite2; And package harfbuzz and harfbuzz-icu separately. Overview of changes leading to 0.9.17 Monday, May 20, 2013 ===================================== - Build fixes. - Fix bug in hb_set_get_min(). - Fix regression with Arabic mark positioning / width-zeroing. Overview of changes leading to 0.9.16 Friday, April 19, 2013 ===================================== - Major speedup in OpenType lookup processing.

So, one needs ragel to bootstrap from the git tree. API changes: - hb_shape() and related APIs now abort if buffer direction is HB_DIRECTION_INVALID. Previously, hb_shape() was calling hb_buffer_guess_segment_properties() on the buffer before shaping. The heuristics in that function are fragile. If the user really wants the old behvaior, they can call that function right before calling hb_shape() to get the old behavior. - hb_blob_create_sub_blob() always creates sub-blob with HB_MEMORY_MODE_READONLY. See comments for the reason. Overview of changes leading to 0.9.12 Thursday, January 18, 2013 ===================================== - Build fixes for Sun compiler. - Minor bug fix.
