Do you have any idea about its meaning and origin?<br class="">

Ah, Thank you Richard!</div>
<div>I have recently updated to MacTex 2020 and this change came
with it probably.</div>

L3 (usually lowercase l3) refers to the LaTeX3 project which has
created a suite of macros organized into a programming language
expl3 that is systematic in a way that TeX and LaTeX2e are not
(although in the end the functions/statements in expl3 resolve
themselves into TeX commands). See the documentation in the
l3kernel package, particularly interface3.pdf. Increasing numbers
of packages are being created using expl3. I've managed to write a
couple, one stretching to many thousands of lines of code, whereas
I struggle to cobble 5 lines of (La)TeX together. I presume the
message in LyX means it is using expl3.</p>

I have followed the development of L3 in the beginning but stopped it because it was quite slow to start. I am happy to see that it became a reality now. I started to write my PhD by using TeX before the arrival of LaTeX to France. The syntax of the TeX language was quite headache inducing for me. :-)</div></body></html>
