Round brackets in Chicago style footnote citations

I'm looking for a way to get rid of round brackets in footnotes (around publishers) which are automatically generated using the biblatex-chicago package.

Any suggestions how this could be done? I would like the book citation to appear without brackets, pretty much as it would in the bibliography (here: "John L. Austin. How to do things with words. Cambridge, Mass.: Harvard University Press, 1975.").

\documentclass[12pt,pagesize=auto, titlepage=on]{scrartcl}
\usepackage[utf8]{inputenc}
\usepackage[notes,backend=biber,doi=false,isbn=false,url=false]{biblatex-chicago}
\bibliography{literatur.bib}
\begin{document}

Citation.\autocite{austin1975things}
\end{document}


In order to do this, you need to adjust the macro that prints the location, publisher, and year. For @book entry types this is the macro cpubl+loc+year.

Depending on the entry types you use, you may have to adjust other macros as well to make things consistent. You can find the macros you need in chicago-notes.cbx.

In this MWE, I just comment out the part that includes parentheses so you can see what is going on. You also need to replace the \setunit{\addspace} with \newcunit to ensure that a comma is inserted before the location.

\documentclass{article}
\usepackage[notes,backend=biber,doi=false,isbn=false,url=false]{biblatex-chicago}
\bibliography{biblatex-examples.bib}
\renewbibmacro*{cpubl+loc+year}{% Revised for reprint
\ifboolexpr{%
test {\iflistundef{location}}%
and
test {\iflistundef{publisher}}%
and
test {\iffieldundef{year}}%
and
not togl {cms@reprint}%
}%
{}%
\newcunit
%\printtext[parens]{% <- remove parentheses
\usebibmacro{origpubl+loc+year}%{cmsorigdate}%\printfield{origyear}%
\ifboolexpr{%
togl {cms@reprint}%
and
not test{\ifentrytype{video}}%
}%
{\bibsstring{reprint}%
\newcunit}%
{}%
\printlist{location}%
\iflistundef{publisher}%
