Edit: I found the PR that changed this default: [v5.4.0] Update configuration defaults by Jermolene · Pull Request #9107 · TiddlyWiki/TiddlyWiki5 · GitHub
There is some discussion too. So if you disagree with the new default – Lets us know.
But is did not change the default shadow. I can not find the PR, that changed this value. … That’s strange.
IMO the default should be “Wrap long lines in code blocks : Yes” … We only needed to change this one for easy testing the PR.
Long lines should look like this. … So if your wiki shows text outside of the tiddler, you need to check your Style sheet settings.
The default can be changed in
ControlPanel → Appearence → Theme Tweaks → Warp long lines in code blocks
