### Changes

* [#1649](https://github.com/rubocop/rubocop-rails/pull/1649): Allow frozen array/hash literal (e.g. `[].freeze`, `{}.freeze`) as `:default` value in `Rails/AttributeDefaultBlockValue`. ([@kuboon][])
* [#1652](https://github.com/rubocop/rubocop-rails/pull/1652): Improve `Rails/HttpPositionalArguments` performance by checking for `include Rack::Test::Methods` once per file instead of once per HTTP call. ([@moberegger][])
* [#1650](https://github.com/rubocop/rubocop-rails/pull/1650): Speed up loading rubocop-rails by lazily loading only the cops and mixins needed for a run. This requires RuboCop 1.89.0+. ([@koic][])
