No revtex4-2.layout ?

Thu Apr 2 16:09:18 UTC 2020

Dear LyX users,
I am lacking a "revtex4-2.layout" in my (latest) LyX ver. 2.3.4.2. Is 
this really true?
Stemming from the APS, the revtex package is probably among some of the 
most heavily used latex packages in natural science and physics. The 4.2 
version of revtex is out since more than a year. Yet my LyX only shows a 
revtex4-1.layout. What am I missing? Can I get this from somewhere else?
