	aa58b43d	2025-09-12T14:24:41		[subset] Introduce HB_SUBSET_FLAGS_RETAIN_NUM_GLYPHS. (#5547) Used in conjunction with retain gids, when set the num glyphs from the input font will be preserved. Empty glyphs will be inserted as necessary to maintain the num glyphs value. Put under experimental for now.
	416e6b69	2025-04-16T20:21:27		11.1.0
	efcb7d3d	2025-04-11T23:34:06		[subset] close unicodes over bidi mirror variants during subsetting. Fixes #5281. Does the closure by default, but I've introduced a new flag and option to disable this behaviour since some users may want to get the minimal set if they know they don't need the mirrored variants.
	623a7a41	2025-04-04T13:25:06		Whitespace
	a1e587b7	2025-03-31T22:02:11		[subset] Add hb_subset_cff_get_charstrings_index and hb_subset_cff2_get_charstrings_index. These methods allow retrieving the entire charstrings index structure from a CFF or CFF2 table.
	82d66451	2025-03-27T17:47:56		[subset] Fix check-symbols test
	ae8b288d	2025-03-27T22:07:01		[subset] Correctly handle lifetime of charstrings data blob returned by hb_subset_cff_get_charstring_data.
	0d4053b1	2025-03-27T18:45:12		[subset] Add hb-subset.h API for retrieving the raw per glyph outline data from CFF and CFF2.
	3bb89eeb	2024-11-24T17:00:14		[instancer] use hb_parse_double() for parsing axis positions Added hb_subset_axis_range_from/to_string()
	71b1ba7a	2024-05-13T23:07:51		8.5.0
	4cf606f6	2024-05-02T20:46:29		[instancer] Promote partial instancing api out of experimental.
	d6431dc7	2024-03-06T15:20:10		[instancer] support *=drop, which would pin all axis to default location
	97309483	2024-02-02T16:59:19		[instancer] rename HB_SUBSET_FLAGS_IUP_DELTA_OPT to HB_SUBSET_FLAGS_OPTIMIZE_IUP_DELTAS
	c7a6030b	2024-01-26T09:27:27		[instancer] add a flag HB_SUBSET_FLAGS_IUP_DELTA_OPT
	d30c1dac	2023-11-15T20:16:07		Add test suite for instancing option parsing.
	43236ce3	2023-11-01T22:34:39		[instancer] add the option to leave blanks in the min:def:max syntax. When parsing axis positions in the --variations flag recognize empty values as meaning the existing value for that part. For example: :300:500 Specifies min = existing, def = 300, max = 500. See: https://github.com/fonttools/fonttools/issues/3322
	c6884377	2023-11-06T20:21:46		[subset] Add HB_SUBSET_FLAGS_IFTB_REQUIREMENTS flag. When enabled the output subset conforms to the requirements for a base font to be patched by IFTB patches. IFTB is a proposed incremental font transfer patch. This new flag is set as experimental. Currently, setting this flag causes the output subset to also use long offsets for outline data in loca/glyf, gvar, CFF, and CFF2. This change is a version of https://github.com/skef/harfbuzz/commit/3ae2fe2084d96f61d8ad1bbe42a6ef4e62ec830a rebased onto head w/ tests added.

It has been decided that future flags will also be false by default for simplicity (using NO_ in the name if needed). Correct and simplify the documentation for hb_subset_flags_t to reflect this.
	f9d8e4a9	2021-07-29T15:25:41		[subset] switch ..._set_flags to not take a mask.
