Today's update

[Herbert Schulz]

Howdy,

In updating my TeX Live 2019 this morning using tlmgr (via TeX Live Utility (TLU) and
NOT the one in tlcritical) on my Mac I noticed that when running

/Library/TeX/texbin/tlmgr --repository http://ctan.math.utah.edu/ctan/tex-archive/systems/texlive/tlnet --machine-readable --persistent-downloads update --all)

there was the message

regenerating fmtutil.cnf in /usr/local/texlive/2019/texmf-dist

(again, using TLU) and many formats were rebuilt:

including latex, pdflatex, lualatex (and their -dev versions) but while the xelatex-dev version was rebuilt the xelatex version was not mentioned. Is that correct?

Good Luck,
