Antlers changes in v6 not mentioned in Upgrade Guide #1826
Description
I recently upgraded to v6 from v5 and I had multiple issues regarding antlers. I have documented my issues in statamic/cms#13856, and I'm still not sure what actually changed in v6, but some things definitely changed that broke my site (and I didn't see anything about it in the upgrade guide).
Anyways, if I was just doing something weird or you don't think there's anything worth mentioning in the upgrade guide, feel free to close this issue. But I think it's something that's worth looking into, given that this broke multiple pages in production and if it weren't for Nightwatch I wouldn't have noticed (unless some visitors told me, of course 😅).
