Hi, As we're progressing with the lmtx project (aka luametatex + context) the codebase gets adapted a bit. There are a few things that you need to keep an eye on: - As we test with lua 5.4 it can be that you need to wipe the cache after an update due to differences in byte code. This is only needed when you run into issues. At some point there might be a split in lua code (for luatex and luametatex) as 5.2 (luajittex, not evolving), 5.3 (luatex, stable frozen) and 5.4 (luametatex, experimental progressing) have a couple of different properties that we might want to benefit from. - The code base gets split in "Mark Four" and "Mark Fourty" files. Some of these are permanent, some can be temporary. It can for instance relate to features in and experiments with the engine. The only convenient way to test things is in 'real situations' and often issues can be solved fast. - As we're experimenting with metafun (and luagraph and ...) we also explore new interfaces. This results in a different codebase but should go unnoticed for existing code. Of course metafun 2.0 (hip and modern internet version speak) can bring interesting new things in the end. As usual, happy testing.
