+ * Standard source tree structure: the code is now located in the ./doc,
+ ./scripts, ./src, ./build, and ./misc directories.

+ luaotfload-database (fontconfig) into the new file
+ luaotfload-parsers.lua.
+ * Move logging routines from luaotfload-override in to luaotfload-log.

+ * Remove imported version of typo-krn.lua. Xetex-style per-font
+ letterspacing is now the canonical method.

+ 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

+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")

+ * 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:

+ * fixing font cache file name with non-ascii characters
+
+2013/04/25, luaotfload v1.29:
+ * Reverting the unified resolver, as the database was rebuilt too often
+ which made the compilation longer. This will come back improved
+ in the next version, hopefully for TeXLive 2013.
