Overview of changes leading to 2.9.1
Tuesday, September 7, 2021
====================================
- Final subset API is in place and if no issues are discovered, it will be the
stable subset API of HarfBuzz 3.0.0. Old API is kept to ease transition, but
will be removed in 3.0.0.
- Various fuzzer-found bug fixes.
- hb_buffer_append() now handles the pre- and post-context which previously
were left unchanged in the destination buffer.
- hb-view / hb-shape now accept following new arguments:
o --unicodes: takes a list of hex numbers that represent Unicode
codepoints.
- Undeprecated API:
hb_set_invert()
Overview of changes leading to 2.9.0
Wednesday, August 18, 2021
History Repeats Itself (Afghanistan)
====================================
- Subsetter API is being stabilized, with the first stable API to happen in
3.0.0 release (https://github.com/harfbuzz/harfbuzz/issues/3078).
- Support multiple variation axes with same tag, aka HOI.
- The “coretext” testing shaper now passes font variations to CoreText.
- hb-shape/hb-view does not break line at new lines unless text is read from
file.
- hb-view and hb-subset has a --batch now, similar to hb-shape.
- The --batch mode now uses ; as argument separator instead of : used previously.
- The --batch in hb-shape does not expect 0th argument anymore. That is, the
lines read are interpreted as argv[1:], instead of argv[0:].
- The --batch option has been undocumented. We are ready to document it; send
feedback if you find it useful.
- hb-subset got arguments revamps. Added much-requested --gids-file, --glyphs,
--glyphs-file, --unicodes-file, supporting ranges in --unicodes.
- Various bug fixes.
Overview of changes leading to 2.8.2
Tuesday, July 8, 2021
====================================
- Shaping LTR digits for RTL scripts now makes the native direction of the
digits LTR, applying shaping and positioning rules on the same glyph order as
Uniscribe. (Jonathan Kew, Khaled Hosny).
- Subsetting COLR v1 and CPAL tables is now supported. (Garret Rieger, Qunxin Liu)
- Various fixes and improvements to the subsetter. (Garret Rieger, Qunxin Liu, Behdad)
- When applying morx table, mark glyph widths should not be zeroed. (Jonathan Kew)
- GPOS is preferred over kerx, if GSUB was applied. (Behdad)
- Regional_Indicator pairs are grouped together when clustering. (Behdad)
- New API:
+hb_blob_create_or_fail()
+hb_blob_create_from_file_or_fail()
+hb_set_copy()
