This question already has an answer here:

So, after waiting until today (Jan. 8) to try updating pgf for my MikTeX install(s), went ahead and gave it a try (first after backing everything up in my MikTeX root directories).

Install pgf using MikTeX update console. The package information for the update is v. 3.1, build 7 January, 16:11 EST 2019.

However, for any document using some of the PSTricks packages I use, updating pgf causes some compile errors. Here is an mwe, with the error message at the bottom:


 %% uncommenting any of the following causes a compile error
 % \usepackage{pst-node}
 %  \usepackage{pstricks-add}
 %  \usepackage{pst-func}


 here is some text...


If you uncomment any of the PS packages, you get the following error(s) -- here, after uncommenting pst-node:

 Command Line:   latex.exe --enable-write18 --src "mwe_pgf.tex"
 Startup Folder: E:\books\mark2019\misc code\mwe

 This is pdfTeX, Version 3.14159265-2.6-1.40.19 (MiKTeX 2.9.6930 64-bit)

Updated pgf now plays nice with tikz (as far as I can tell), but not PSTricks. Which creates an enormous problem for people who use the latter.

If anyone can confirm the issue at their end, I'll post a bug report. Until then, back to the old (but still working) pgf package for me.
