Minted v3 errors when using \includeonly

[tippex-ls]

Hi !
With the minted v3 release, I noticed that it breaks my documents when I use \includeonly.
minted version : 3.1.2
Everything else related is up to date.

Here is a MWE :

% mwe.tex
\documentclass{article}

\usepackage{minted}

% \includeonly{mwe2.tex}

\begin{document}
\include{mwe1.tex}
\include{mwe2.tex}
\end{document}

% mwe1.tex
\begin{minted}{ocaml}
  let ex_1 = 0
\end{minted}

% mwe1.tex
\begin{minted}{ocaml}
  let ex_2 = 0
\end{minted}

My compilation process is :

$ latexmk mwe
# Everything works

# uncomment the includeonly command
$ latexmk mwe
[...]
(./mwe.aux (./mwe1.aux) (./mwe2.aux))

! LaTeX Error: No counter 'minted@tmpdatabufferlength' defined.

See the LaTeX manual or LaTeX Companion for explanation.
Type  H <return>  for immediate help.
 ...

l.8 \include{mwe1.tex}

?

This was not a problem in minted v2.*, this compilation process works when using minted2 instead of minted (with --shell-escape).

Is this an expected regression with the new version ? Thanks for your help.

\includeonly changes the way that counters behave, so fixing this also involved modifying latex2pydata and fvextra. You can download the dev version of minted.sty as well as the dev versions of latex2pydata.sty and fvextra to try the new version immediately. Otherwise, new releases of all packages will be on CTAN within the next few days.
