Hi everyone
I updated Stroll, and its empty file, to TW version 5.2.5.
If you have Stroll, do to the TiddlyWiki upgrade Wizard (https://tiddlywiki.com/upgrade.html) and upgrade your file if you haven’t already. Save a backup before doing so, just to be safe.
Then go to https://giffmex.org/stroll/stroll.html#Updating%20Stroll, and drag the tag pill "$:/giffmex/stroll"
to your file. This is so that one or two overwritten system tiddlers stay overwritten. The upgrade process “un-overwrites” them, so dragging the pill “re-overwrites” them.
