Hi,
There is a new lmtx upload.

-- The svg inclusion via metapost has been upgraded and = cleanup a bit, using some more recent metapost features. There are some = new (not yet all documented metapost) features.

-- In the process, support for LCH colors has been added, = which is documented in the (eg luametafun manual).

-- The math manual is not yet there because we were = distracted by improving support for envelopes (penbased outlines) in = metafun. This is still work in progress, some is present and discussed = in the manual, and we'll come back to that sometime next month. Given = the next item, we also might need to change some in the manual = (different focus).

-- Because we have users = who have to conform to the European Accessibility Act we have been = wondering how to deal with that and at Mikaels place there are two = demands: distinctive colors and tagging and especially math (somehow = validators love to check that). Colors never were an issue as they can = be controlled, and tagging math neither, especially because nothing = was/is done with it anyway, but ... we are happy that we found a = reasonable (more modern and future proof) way out.

As explained / shown in the attached document we're basically = forced to choose a different approach with math (a pity as we worked = hard to get the rendering right but the attached file works fine in the = viewers that we tested).

-- We like to hear = from users what other demands wrt accessibility there are. We're not = interested in the (commercial) big money aspects (of pdf and tagging) = nor in the politics behind it (changes over time). What are the demands, = so that we can see how to make it work or just work around it (as it's = kind of boring to cook uyp complex features , esp compared to playing with = metapost).

-- Furthermore .. the usual bits = and pieces as discussed on the list and otherwise.

-- If you have troubles (crash) you need to wipe the cache = due to a change in lua bytecode storage (no easy way to catch it).
