Changes

:* Arabic support is good enough for critical editions of historical Islamic texts or typesetting the Qur’an, thanks to the Oriental TeX project. Support for Indic languages and CJK is also good (vertical is limited, sorry).

:* [[Layers]] and [[Overlays]] are fun.

:* Debugging features (`\show…` commands, [[Trackers]], directives, code checking) included; no useless TeX command line stops any more.

:* The whole distribution is really slim and contains the LuaMetaTeX source code (no external dependencies, easily compilable on a wide range of architectures). This affects also [https://islandoftex.gitlab.io/community/projects/docker/ docker containers].
