Hi Hans,I made a fresh installation of today's LMTX update in a separate tree on Ubuntu (linux-64), rather than updating my existing installation.
The installation completed without problems. I get: ConTeXt 2026.10.01 18:42 LMTX LuaMetaTeX 2.11.10, functionality level 20260923 Lua 5.5|mtxrun.lmt|and |context.lmt|are both found correctly, alongside |mtxrun.lua|, and normal processing works as expected.
I also tested the |.notdef|changes. When loading several Latin Modern CFF fonts from a fresh cache, ConTeXt reported, for example:
|otf reader > cff > missing .notdef, using a rectangle instead|This occurred with Latin Modern regular/bold/italic/bolditalic and also with the math fonts. The generated PDF rendered without problems in Evince and Firefox/PDF.js, and Poppler/Cairo (|pdftocairo|) rasterized it without errors. |pdffonts|identifies the embedded Latin Modern subset as CID Type 0C, Identity-H, embedded/subsetted with Unicode mapping.
I then compiled the attached slightly broader test document, exercising text and font variants, Unicode, OpenType math, a table, colors, MetaFun/MPLIB and the PDF backend. It compiles cleanly in two passes and produces the attached PDF.
So far I have not found any problem with the new installer/tooling or with the |.notdef|changes on this Ubuntu installation.
I attach the test source and resulting PDF. Best, Jean-Pierre Le 01/10/2026 à 19:03, Hans Hagen via ntg-context a écrit :
Hi, I pushed an update: -- the installer is upgraded -- therefore we need a few tests before we're sure all is ok -- so either wait or make a copy, update and report back -- the changes are: -- a bit more efficient download (some 30% gain due to better saturation of bandwidth) -- https (as an option) -- we also move to mtxrun.lmt (and context.lmt) which should just work (alway swas possible) but is now default for lmtx -- the mtxrun.lua fils is for luatex (mkiv) -- this means that i can move some more into .lmt files which in some cases can be more efficient and less code -- also, by being decouples we can let mtxrun move forwardIt somethign is broken, sorry, but it's fixable (like some file missing or so). Also, an update that concerns a bit change in tooling is always kind of tricky and hard to test.-- There has been some .notdef relates upgrade (hopefully satisfying all viewers) so please report issues with that.Hans
