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.
Oxygen Font is a project to design a desktop/gui font for integrated
use with the KDE desktop.
The basic concept for Oxygen Font is to design a clear, legible, sans
serif font which would be rendered with Freetype on Linux-based
devices. In addition a bold weight, plus regular and bold italics, and
a monospace version will be made.
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.
--------------
1.05 (r1069, 2015-01-26)
* Add support for GSUB Type 8 Reverse-chaining substitution
* OpenType script/lang/feature tags now based on ISO/IEC 14496-22
* Remove deprecated GDL_old.pm
*
* Bug fixes:
* Fix rt.cpan.org 92150, 93597
* Force 0xFFFF sentry to be in a segment by itself in format 4 cmap subtables
* Less aggressive cmap format 4 optimization to eliminate USV holes
* Fix various issues reading WOFF-compressed font tables
* Fix reading DSIG
the symptom being that ftttdrv.h (from freetype2) is not found. It
turns out that native X11 doesn't install ftttdrv.h for some reason
(probably an oversight) but that the lack is easily compensated
because the whole file contains only two substantive lines, neither of
which appears to be especially important.
PR 50902.
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 stablize 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/behdad/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/behdad/harfbuzz/issues/21186c68c7a2c
- Graphite2 shaper: improved negative advance handling (eg. Nastaliq).
- Add nmake-based build system for Windows.
- Minor speedup.
- Misc. improvements.
The font families PT Sans and PT Serif were released in 2009-2010
with an open user license. The main aim of the project is to allow
the peoples of Russia to read and write in their native languages.
The project is dedicated to the 300-year anniversary of the civil
type invented by Peter the Great in 1708-1710 and was realized with
financial support from the Federal Agency for Press and Mass
Communications.
The fonts, beside the standard Western, Central European and Cyrillic
code pages, also contain characters of all title languages of the
Russian Federation.
2.0.14:
Ryan Gordon - Fri Jan 29 12:53:29 PST 2016
* Deprecated TTF_GetFontKerningSize() which takes font glyph indices
and added TTF_GetFontKerningSizeGlyphs() which takes characters
The STIX fonts are a suite of unicode OpenType fonts containing
a complete set of mathematical glyphs. This otf package makes
the fonts available to X11 apps.

Code New Roman is aimed for use in programming environments and
other circumstances where a monospaced font is specified. All
characters have the same width, like old typewriters, making it a
good choice for programmers. This font improved and target to Mac
OS Western New Roman, MONACO, Windows Consolas/Lusida Consolas,
ABeeZee and Bitstream Vera Sans Mono.This font display allowed a
design with proportions closer to normal text than traditional
monospaced fonts like Courier. This allows for more comfortably
reading of extended text on screen. OpenType features include
hanging or lining numerals; slashed, dotted and normal zeros; and
alternative shapes for a number of lower-case letters. The look of
text can be tuned to personal taste by varying the number of bars
and waves.
The design of Cutive, and this monospace sister family Cutive Mono,
is based on a number of classic typewriter typefaces, in particular
the faces of IBM's 'Executive,' and the older 'Smith-Premier.' In
Cutive these old faces re-emerge as webfonts that are useful for
adding character to body texts as well as in larger sizes for
headers and display.
Programming languages are limited to relatively few characters. As
a result, combined character operators surfaced quite early, such
as the widely used arrow (->), comprised of a hyphen and greater
sign. It looks like an arrow if you know the analogy and squint a
bit.
Composite glyphs are problematic in languages such as Haskell which
utilize these complicated operators (=> -< >>= etc.) extensively.
The readability of such complex code improves with pretty printing.
Academic articles featuring Haskell code often use lhs2tex to
achieve an appealing rendering, but it is of no use when programming.
Some Haskellers have resorted to Unicode symbols, which are valid
in the ghc. However they are one-character-wide and therefore
eye-strainingly small. Furthermore, when displayed as substitutes
to the underlying multi-character representation, as vim2hs does,
the characters go out of alignment.
Hasklig solves the problem the way typographers have always solved
ill-fitting characters which co-occur often: ligatures. The underlying
code stays the same - only the representation changes. Not only
can multi-character glyphs be rendered more vividly, other problematic
things in monospaced fonts, such as spacing can be corrected.
Fira Code is a Fira Mono font extended with a set of ligatures for
common programming multi-character combinations. This is just a
font rendering feature: underlying code remains ASCII-compatible.
This helps to read and understand code faster. For some frequent
sequences like .. or // ligatures allow us to correct spacing.
Office Code Pro is a customized version of Source Code Pro, the
monospaced sans serif originally created by Paul D. Hunt for Adobe
Systems Incorporated. The customizations were made specifically
for text editors and coding environments, but are still very usable
in other applications.
