EMACS error "Package html2text is obsolete"

[Ralph Seichter]

Hello list,

I tried to access https://notmuchmail.org/pipermail/notmuch/ several
times today, but it always resulted in a connection error, so I am
now trying the mailing list.

When I open a HTML message in the EMACS UI, the error message "Package
html2text is obsolete!" is displayed. Is it possible to configure
Notmuch to use SHR/EWW instead of html2text?
