Change History
--------------
2016/mm/dd, luaotfload v2.7:
* Rework lookup chaining.
* Combining glyphs from different fonts (``combo: ...`` requests).
* Glyph fallbacks.
2015/12/09, luaotfload v2.6
* Add ``sign`` target to makefile for automated package signing.
* Add ``--dumpconf`` option to luaotfload-tool for generating configuration
files.
* Move fontloader files to subtree src/fontloader.
* New script ``mkimport`` facilitates maintainance of code imported from
Context.
* Revised letterspacing, now utilizing the ``node.direct`` interface.
* Revized colorization of fonts, utilizing ``node.direct`` (Dohyun Kim).
* Colorization was moved to the ``post_linebreak_filter`` stage.
* Move remaining functionality from ``luaotfload-override`` into
initialization.
* Write names index if fonts were removed.
* Separate module loading from initialization.
* Custom fontloader package with the files from Lualibs removed.
* Swappable fontloader via configuration option.
* Lualibs are now a dependency when used in a TeX run as well.
* Respect interword spaces when letterspacing.
2014/07/13, luaotfload v2.5
* Remove legacy code.
* Remove compatibility with the old mkluatexfontdb script.
* Remove test directory. Use https://bitbucket.org/phg/lua-la-tex-tests
instead.
* Remove luaotfload.lua from luaotfload.dtx; it is now a separate file
luaotfload-main.lua.
* Standard source tree structure: the code is now located in the ./doc,
./scripts, ./src, ./build, and ./misc directories.
* Move the heavier LPEG parsers from luaotfload-features (syntax) and
luaotfload-database (fontconfig) into the new file
luaotfload-parsers.lua.
* Move logging routines from luaotfload-override in to luaotfload-log.
* Scan local font files (``--local`` flag to luaotfload-tool, flag
``scan_local`` during TeX run).
* Add bisection mode (``--bisect``) to luaotfload-tool.
* Add functions for accessing the database: ``aux.font_index()`` and
``aux.read_font_index()``.
* Distinguish XDG configuration paths (Reuben Thomas)
* Optional configuration via rc files.
* Configure default features via configuration file.
2013/12/31, luaotfload v2.4
* Additional self-tests, now in separate file (luaotfload-diagnostics.lua)
* Better path and directory handling, especially on Windows
* database now indexes Type1 fonts (PFA, PFB) and makes them accessible
with style modifiers (requires --format=+pfa,pfb option to luaotfload-tool)
* Test runner (script mktests)
* New luaotfload-tool option: ``--no-reload``
* ``luaotfload-tool --find`` now understands request syntax
* text (Lua script) version of the font index is filtered through gzip by
default, the ``--no-compress`` option of luaotfload-tool will prevent
this
* rename ``luaotfload-merged.lua`` (the fontloader package from Context)
to ``luaotfload-fontloader.lua``
* Treat arguments of the ``letterspace`` option as percentages; add
``kernfactor`` option that behaves as before.
* Remove imported version of typo-krn.lua. Xetex-style per-font
letterspacing is now the canonical method.
* Merge functionality from extralibs (fake Context layer) into
luaotfload-letterspace.lua as it is only needed there anyways.
2013/07/10, luaotfload v2.3a
* Detect LuaJIT interpreter (LuaJITTeX)
* Self-test functionality for luaotfload-tool.lua (option ``--diagnose``)
2013/07/03, luaotfload v2.3:
* New experimental lookups: ``kpse`` (kpathsea), ``my`` (callback)
* Precedence of texmf over system fonts can be requested
using the ``--prefer-texmf`` option of luaotfload-tool
* Resolve file names to full paths at later stage
* Rewrite the output of ``\fontname`` via ``patch_font`` callback
* Allow blacklisting directories
* Drop compatibility layer
* Remove dependency on luaotfload-lib-dir (references to dir.glob() and
dir.mkdirs())
* luaotfload-tool now displays extensive information about a font if given
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)
* Improved and extended documentation
* Font filenames are stored in the database (file: lookups more efficient)
* Optional caching of name: lookups (uses separate cache file)
* Rewriting and increased fidelity of XeTeX emulation
* Renaming mkluatexfontdb into luaotfload-tool (the old behavior is kept if
the script is symlinked or renamed mkluatexfontdb)
* Added options to luaotfload-tool for simple database queries
* Logging facilities have been rewritten and allow for more granularity
* All files have been renamed, abandoning cryptic acronyms; also
the new prefix is "luaotfload" (<= "otfl")
* The Adobe Glyph List (font-age.lua) is now built via script (mkglyphlist)
* Hans adapted the font loader to several of our requests (attribute
allocation, custom merged package name etc.)
* Auxiliary functions for package authors
* Man page for luaotfload-tool
* Unsupported v1.3 codebase is included in the luaotfload-*lua files. Crude,
but effective way to support older Luatex binaries
* implemented basic cache control/stats option for luaotfload-tool
* Character list is generated from char-def.lua (mkcharacters)
2013/04/27, luaotfload v1.3:

2013/04/25, luaotfload v1.29:

in the next version, hopefully for TeXLive 2013.
