Anyone else noticed a difference in the spacing before a lstlisting environment since upgrading to version 1.7 2018/09/02?

Here's a MWE with output with version 1.7 and version 1.6 for comparison.

I can get same output be removing the empty line before the lstlisting environment, but I'd rather not go through old files and do that. And it seems like wrong behaviour anyway.

Is this a bug?

Can anyone suggest a workaround to return things to the old behaviour?

MWE

documentclass{article}

usepackage{listings}

begin{document}

Preceding paragraph.



begin{lstlisting}{}

documentclass{article}

begin{document}

end{document}

end{lstlisting}



Subsequent paragraph.

end{document}

Output with listings 1.7 2018/09/02

Output with listings 1.6 2015/06/04

For an unknown reason lstlistings adds a leavevmode in the code, you can try to disable it until the problem is resolved in the code:

documentclass{article}

usepackage{listings}

makeatletter 

lst@AddToHook{PreSet}{letleavevmoderelax}

makeatother

begin{document}

Preceding paragraph.



begin{lstlisting}{}

xxx

end{lstlisting}





Subsequent paragraph.

end{document}
