It's been a long time, since a solution for the 'module wrapping error' in tikz has been proposed here in the list: https://mailman.ntg.nl/pipermail/ntg-context/2017/090404.html

Since July a fix has been published: https://github.com/pgf-tikz/pgf/commit/9b24e5cdb8246b1075d02c02c75ff8bcac642c16

A few days ago the release containing the fix was released. On contextgarden the manual under modules/t-tikz/doc/generic/pgf shows the current version 3.1.8b, but the source doesn't include the fix. I compared the source on context-garden (rsync://contextgarden.net/minimals/current/modules/) with the zip (https://github.com/pgf-tikz/pgf/archive/3.1.8b.zip). In the zip file the fix is included, so I'm puzzled...

Is there a synchronisation-problem?

Just wanted to mention it. It's not crucial.

Thanks
