More specifically: 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.
