Yep there is a whole chapter in the release notes that something changed with resources and matches:
Resources Loading from Assets with Wildcards : We have added two new sought after template functions to the
resourcesnamespace:resources.Matchandresources.GetMatch. These behaves like their namesake methods onPage(with super-asterisk wildcard support), but searches in all the resources in Assets. E.g.{{ $prettyImages := resources.Match "images/**pretty.jpg" }}will give a slice of all “pretty pictures”. Another relevant example:{{ $js := resources.Match "libs/*.js" | resources.Concat "js/bundle.js" }}.
This is probably connected.
Basically resource.Resource. at the end of the error message sounds suspicious. What line exactly is line 22 in entry.html?
