+* [#1630](https://github.com/rubocop/rubocop-rails/issues/1630): Fix a false positive in `Rails/StrongParametersExpect` when negating `params[:key]` with `!`, such as `!params[:key]`. ([@koic][])
+* [#1629](https://github.com/rubocop/rubocop-rails/pull/1629): Fix false positives in `Rails/StrongParametersExpect` when using the safe navigation operator (`&.`) on `params[:key]`. Autocorrecting `params[:key]&.downcase` to `params.expect(:key).downcase` silently changes behavior — a missing param goes from returning `nil` to raising `ActionController::ParameterMissing`. ([@lucasmazza][])
