Change History
--------------
2022-10-03 luaotfload v3.23
* More reliable ToUnicode mappings in Harf mode
* Various bug fixes
2022-06-15 luaotfload v3.22
* Tailored case mappings
* Avoid database rebuilds when switching Lua versions
* Improved attribute settings of ActualText nodes in harf mode
* Callback-based customization for color parameter
* Various bug fixes
2022-03-18 luaotfload v3.21
* Fix performance regression introduced in version 3.19.
* More reliably support TrueType based variable fonts in harf mode.
2022-02-27 luaotfload v3.20
* A bug in luaotfload-tool has been corrected.
* The directory for the font name database has been corrected and no
longer uses the development directory.
2022-02-24 luaotfload v3.19
* When used with LuaTeX 1.15.0 or newer, variable fonts are supported
when using the harf shaper too.
* A new algorithm for selecting fonts based on font family names allows
to more reliably load fonts based on their family name.
* The compiled font database gets compressed to reduce disk space and
improve performance on newer systems.
* Text automatically gets normalized to Unicode's NFC before shaping.
This improves rendering for text written in decomposed forms for many
fonts. This can be turned off by passing the -normalize font feature.
* The fontloader has been synced with the context code from 2022-02-24.
This fixes some broken rendering of TrueType based variable fonts.
* A number of small bugfixes.
2021-05-21 luaotfload v3.18
* Allow using variable fonts without explicitly specifying any axis values
* The fontloader has been synced with the context code from 2021-05-20
* Multiple small fixes, mostly concerning discretionaries in harf mode.
2021-01-08 luaotfload v3.17
* The fontloader has been synced with the context code from 2021-01-07.
This improves support for advanced CFF based OpenType variable fonts.
2020-12-31 luaotfload v3.16
* The fontloader has been synced with the context code from 2020-12-30
* The entry point is called luaotfload.lua instead of
luaotfload-main.lua (but the old name is still provided for
compatibility).
* pre/post_shaping_filter callbacks has been added.
* The number of lua-files and submodules shown in the log-file
has been reduced. But it is extended again by setting the environment
variable LUAOTFLOAD_TRACE_SUBMODULES=1.
* The HarfBuzz based shaper will in some situations drop hyphenation
points. This happens less frequently now since the new version uses
first/second discretionaries (the mechanism described in the LuaTeX manual,
section 5.6 for the of-f-ice example) to support a limited amount of
nesting.
* When the node shaper is used, experimental support for
OpenType variable fonts has been added. To use them, set the font
feature axis to a comma separated list of axis names and values.
(E.g. axis={weight=600}) The supported axis names and value
range depend on the font.
* The font features upper and lower can be used to map
the text of a font to upper or lowercase before displaying it. Currently
this implements the untailored Unicode case mapping algorithm, but it is
planned to add tailoring later.
* A number of small bugfixes.
2020-09-02 luaotfload v3.15
* The font database is updated more reliably if fonts get deleted.
* In multiple error cases, error messages are shown instead of silently
generating bad output.
* Write glyph ids instead of internal identifiers to DVI files. This
allows using OpenType fonts when working with dvilualatex.
(This requires additional support from the DVI reader)
* The set of font features which are enabled by default has been
changed to be more similar to HarfBuzz.
Especially Above-base mark Positioning (abvm),
Below-base mark Positioning (blwm), Contextual
Alternates (calt), Cursive Positioning (curs),
Distances (dist), and Required Contextual Alternates
(rclt) are now enabled by default for all scripts.
* Added a mathfontdimen font feature which allows emulating
fontdimen values from xetex or traditional \TeX\ math fonts.
* Initial support for variable fonts in node mode.
2020-05-01 luaotfload v3.14
* bug fix for luaotfload-tool, luaotfload-tool --list=basename failed (texlive list)
* fontloader patched to resolve issue #124
2020-05-01 luaotfload v3.13
* A problem with text fonts with minimal math table has been fixed (issue 148.)
In new luaotfload versions, math parameters will only be loaded for fonts with `script=math`.
If you do want to set math parameters for fonts with other scripts, add `-nomathparam`.
We strongly recommend against setting math parameters for text fonts because
these would overwrite parameters from actual math fonts.
* A bug in harf-mode that could lead to missing chars and freezing was corrected (issue 141).
* A font size problem in harf-mode has been fixed (issue 147).
* An error if the main function was called twice has been fixed (issue 145).
* Allow .ttf fonts to be loaded with a map file with luahbtex (issue 142) (issue 143).
* Fonts installed for a single user on windows are now found (issue 138).
* A problem with wrong \TeX-ligatures in harf mode has been fixed (issue 139).
* The debugging output has been changed (issue 131).
* a missing U+1E9E (Capital ß) in a font is replaced by
SS instead of giving a missing character.
* extended the color handling to be compatible with the luacolor package
* sync with context files from 2020-04-30
2020-02-02 luaotfload v3.12
* new experimental feature multiscript
* new experimental feature fallback
* extension of the color feature to color output glyphs
* Small bug correction
2019-11-10 luaotfload v3.11
* Changed the handling of the script key in harf mode to be more compatible with behaviour of the node mode.
It now expects the name of a script that is actually in the font instead of a ISO 15924 script tag. See issue 117.
* Corrected a number of small typos and bugs in harf mode.
2019-11-04 luaotfload v3.1
* added code to use the harfbuzz library of luahbtex ("mode=harf")
* fonts in ttc can now be indexed by name

* repaired broken letterspace (issue #38)

the argument --inspect
2013/05/20, luaotfload v2.2:
* There is now a central, non-personal dev repo on github:
https://github.com/lualatex/luaotfload
* Synchronisation with ConTeXt from TeXLive 2013, inducing
backward-incompatible changes in the font structure. A
backward-compatibility layer has been added for the current
versions of fontspec, unicode-math and microtype, but it should
disapear in a future version.
* Synchronisation with ConTeXt is now easier and can be done by just
updating luaotfload-merged.lua (<= luatex-fonts-merged.lua from
the LuaTeX-Plain format)

* Font filenames are stored in the database (file: lookups more efficient)
* Optional caching of name: lookups (uses separate cache file)

the script is symlinked or renamed mkluatexfontdb)

allocation, custom merged package name etc.)
* Auxiliary functions for package authors

* Unsupported v1.3 codebase is included in the luaotfload-*lua files. Crude,
but effective way to support older Luatex binaries
