Hi, It's about end of the year, so I updated lmtx. The most significant "change" is that columnsets are in the processed of being replaced which involves a "change in approach". As a consequence, when you use that mechanism - we're not sure how many actually do - and want the old code to kick in you need to load the "oldcolumnsets" module. Mikael S and I have been working on the new implementation but are not finished. We plan to have a reasonable stable version around may 2025 and a release at the ctx 2025 meeting when we also hope to have a new (additional) manual ready. We also test on real (complex) documents which triggers new challenges and solutions. The current code works ok but can best not be used for production (and some new features are undocumented anyway). Teaser: deep down the approach is quite different from the previous one but more reliable and it produced better quality output. Columnsets are also the mechanism that parallel document(stream)s will use. Like upgraded math and (multipass) paragraph optimization the mechanisms used are also a quite fundamental extensions that will be documented independently and likely used elsewhere.
