In the recent versions of LMTX I've been having trouble with finding my own typescriptfile -- type-sourceserifpro.tex (attached)

This file lives in the working directory of all of the other project files, and is also here:

~/lmtx-20201218/tex/texmf-fonts/tex/context/user/type-sourceserifpro.tex

This file is found and executes correctly with:

lmtx-20200920

but fails with:

lmtx-20201218:

fonts           > typescripts > unknown library 'sourceserifpro'

(Latin Modern is substituted for Adobe's Source Serif Pro.)

My setups haven't changed and are:

\usetypescriptfile[sourceserifpro]

\setupbodyfont[sourceserifpro,11pt]

following what's found here:

https://wiki.contextgarden.net/Use_the_fonts_you_want

Does anyone have any thoughts on this?

There has been a change in the naming of typescript file, a simple "type-" prefix isn't anough anymore, you have to change it to "type-imp-" (e.g. type-imp-sourceserif.tex) to be found by ConTeXt. Valid file extensions for a typescript file in LMTX (and MkIV) are "tex", "mkiv" and "mkxl". Wolfgang
