fixed a doc bug in the CHANGELOG.md s/does no longer depend on/no longer depends on/
Use ActiveRecord::Base#update! instead of #update_attributes!
Add 2 tests, 1 of which fails, to isolate the digest_caching behaviour causing #12521

If config.action_view.cache_template_loading = false, most likely in a development
configuration if config.cache_classes = false &
config.action_controller.perform_caching = true.

config.action_view.cache_template_loading defaults to the value of config.cache_classes
Ensure ActionView::Digest.cache is correctly cleaned up when
ActionView::Resolver.caching = false.

Pluck on NullRelation accepts a list of columns

`pluck` was updated to accept a list of columns, but the `NullRelation`
was never updated to match that signature. As a result, calling `pluck`
on a `NullRelation` results in an `ArgumentError`.
