4.46.0 (released 2023-12-02)
----------------------------
- [featureVars] Allow to register the same set of substitution rules to multiple features.
The ``addFeatureVariations`` function can now take a list of featureTags; similarly, the
lib key 'com.github.fonttools.varLib.featureVarsFeatureTag' can now take a
comma-separateed string of feature tags (e.g. "salt,ss01") instead of a single tag (#3360).
- [featureVars] Don't overwrite GSUB FeatureVariations, but append new records to it
for features which are not already there. But raise ``VarLibError`` if the feature tag
already has feature variations associated with it (#3363).
- [varLib] Added ``addGSUBFeatureVariations`` function to add GSUB Feature Variations
to an existing variable font from rules defined in a DesignSpace document (#3362).
- [varLib.interpolatable] Various bugfixes and rendering improvements. In particular,
a new test for "underweight" glyphs. The new test reports quite a few false-positives
though. Please send feedback.
4.45.1 (released 2023-11-23)
----------------------------
- [varLib.interpolatable] Various bugfixes and improvements, better reporting, reduced
false positives.
- [ttGlyphSet] Added option to not recalculate glyf bounds (#3348).
4.45.0 (released 2023-11-20)
----------------------------
- [varLib.interpolatable] Vastly improved algorithms. Also available now is ``--pdf``
and ``--html`` options to generate a PDF or HTML report of the interpolation issues.
The PDF/HTML report showcases the problematic masters, the interpolated broken
glyph, as well as the proposed fixed version.
This works around an issue with detecting whether all required libraries are
runtime dependencies. gtk-doc is a build-only dependency, which causes bl3
to tag glib2 and all of its dependencies as build too. Later inclusion of
glib2 marks it as a full dependency, but include guards mean all of its
dependencies are not. Including glib2 first is a hack, but does resolve the
problem for now.
Victor Mono is an open-source monospaced font with optional
semi-connected cursive italics and programming symbol ligatures.
The typeface is slender, crisp and narrow, with a large x-height
and clear punctuation, making it legible and ideal for code. It
comes in seven weights and Roman, Italic and Oblique styles.
Spleen 2.0.1 (2023-11-17)
- Add a 'com' target to generate SPLEEN.COM, the DOS version of Spleen
- Also add 'com' in the 'all' target
- Update README to add a link to the Guix package
- In the Spleen loader for DOS, put 4C00h in ax and not 4Ch

- Add a new FAQ file answering frequently asked questions about Spleen
- Remove C0 control characters range in the 8x16, 16x32, and 32x64 versions
4.44.3 (released 2023-11-15)
- [subset] Only prune codepage ranges for OS/2.version >= 1, ignore otherwise
- [instancer] Ensure hhea vertical metrics stay in sync with OS/2 ones after instancing
MVAR table containing 'hasc', 'hdsc' or 'hlgp' tags
4.44.2 (released 2023-11-14)
- [glyf] Have ``Glyph.recalcBounds`` skip empty components (base glyph with no contours)
when computing the bounding box of composite glyphs. This simply restores the existing
behavior before some changes were introduced in fonttools 4.44.0
4.44.1 (released 2023-11-14)
----------------------------
- [feaLib] Ensure variable mark anchors are deep-copied while building since they
get modified in-place and later reused.
- [OS/2|subset] Added method to ``recalcCodePageRanges`` to OS/2 table class; added
``--prune-codepage-ranges`` to `fonttools subset` command

micro-optimizations (#3300).
- Require unicodedata2 >= 15.1.0 when installed with 'unicode' extra, contains UCD 15.1.
Instead of depending on one of the removed packages (that are now included
in the base Python packages), include batteries-included.mk to require
a Python version that supplies them.

Leah Fonts is a collection of bitmap fonts designed by Leah Neukirchen,
for those who still prefer a crispier look over TrueType.
Included fonts are:
* sq - 7x15 pixel font inspired by Codec and Quadraat Sans Mono.
Public domain, 2012. Covers full Latin-1 range. Normal and bold.
* 5x13 - condensed pixel font built on 6x13. A well readable font that
is only five pixels wide, such that you can fit four 80-chars wide
shells next to each other on a 1600x1200 display. Partial Latin-1
support (German subset). Normal only.
* smalltalk10 - the font of the Smalltalk 80 system. A pixel perfect
restauration of the Smalltalk 80 variable width font "sans-serif 10" as
provided in the image tape by Mario Wolczko, using the emulator by Dan
Banay. Covers only printable 7-bit ASCII. Normal shape only.

# Changes (upstream)
Version: 4.7
Date : 23 February 2004

distributions that don't come with the 100dpi.
4. Fixed a problem with the OpenType hinting flag not being updated after
being changed.
5. Changed all TrueType references to OpenType to reflect the move to
FreeType 2.
6. Renamed some of the files that referred to TrueType (bdfttf.c and ttfin.c
renamed to bdfotf.c and otfin.c).
7. Removed an unecessary copy when padding character cell glyphs.
8. Some minor documentation improvements.
9. Fixed several serious problems loading Windows FON/FNT fonts.
10. Added comments about conversion to imported FON/FNT fonts.
11. Added comments about conversion to imported OTF fonts.

the file.
2. Released as Linux binary only.
Alan Coopersmith (1):
Remove "All rights reserved" from Oracle copyright notices
Peter Hutterer (2):
Replace unicode files with ones that provide better terms of use
font-util 1.4.1
This package includes a set of bitmap fonts derived from the
artwiz-fonts collection. These fonts are rather small and make
a good fit for old CRTs and lower display resolutions.
Included fonts are:
* lime: improved version of artwiz-lime with better kerning, distinct
characters, extended unicode support, Powerline compatibility, and
in-built icon characters.
* antidote: artwiz-cure mod with lemon-like characters.
* uushi: monaco mod.
* limey: artwiz-lime mod by @spectrum that served as the basis for
lemon.
* berry: monaco mod by @spectrum, with the addition of a Bold variant.
Marc Lehman's bitmap font designed for low resolution displays.
Suxus is a mod of nexus and tixus fonts with the addition of the
missing VT-100 graphical characters, Latin-9 enconding support and
improved readibility.

glyph average weights
4.41.1 (released 2023-07-21)
----------------------------

- [statisticsPen] Report font glyph-average weight/width and font-wide slant.
- [fontBuilder] Fixed head.created date incorrectly set to 0 instead of the current
timestamp, regression introduced in v4.40.0
- [varLib.merger] Support sparse ``CursivePos`` masters

====================================
- Build fix on 32-bit arm.
- More speed optimizations:
- 60% speedup in retaingids subsetting SourceHanSans-VF.
- 38% speed up in subsetting (beyond-64k) mega-merged Noto.
- 16% speed up in retain-gid (used for IFT) subsetting of NotoSansCJKkr.
Overview of changes leading to 8.0.0
Sunday, July 9, 2023
====================================
- New, experimental, WebAssembly (WASM) shaper, that provides greater
flexibility over OpenType/AAT/Graphite shaping, using WebAssembly embedded
inside the font file. Currently WASM shaper is disabled by default and needs
to be enabled at build time. For details, see:
https://github.com/harfbuzz/harfbuzz/blob/main/docs/wasm-shaper.md
For example fonts making use of the WASM shaper, see:
https://github.com/simoncozens/wasm-examples
- Improvements to Experimental features introduced in earlier releases:
- Support for subsetting beyond-64k and VarComposites fonts.
- Support for instancing variable fonts with cubic “glyf” table.
- Many big speed optimizations:
- Up to 89% speedup loading variable fonts for shaping.
- Up to 88% speedup in small subsets of large (eg. CJK) fonts (both TTF and
OTF), essential for Incremental Font Transfer (IFT).
- Over 50% speedup in loading Roboto font for shaping.
- Up to 40% speed up in loading (sanitizing) complex fonts.
- 30% speed up in shaping Gulzar font.
- Over 25% speedup in glyph loading Roboto font.
- 10% speed up loading glyph shapes in VarComposite Hangul font.
- hb-hashmap optimizations & hashing improvements.
- New macro HB_ALWAYS_INLINE. HarfBuzz now inlines functions more aggressively,
which results in some speedup at the expense of bigger code size. To disable
this feature define the macro to just inline.
- New API:
+HB_CODEPOINT_INVALID
+hb_ot_layout_get_baseline2()
+hb_ot_layout_get_baseline_with_fallback2()
+hb_ot_layout_get_font_extents()
+hb_ot_layout_get_font_extents2()
+hb_subset_input_set_axis_range()
