 ### Upgrading to >= 3.3
 
+#### Minimum required Ruby is now 3.3
+
+Grape no longer supports Ruby 3.2; 3.3 is now the minimum (`required_ruby_version = '>= 3.3'`). Upgrade your runtime to Ruby 3.3 or newer before bumping Grape.
+
 #### `Grape::Exceptions::ValidationErrors.new` keyword renamed `errors:` → `exceptions:`
 
 `Grape::Exceptions::ValidationErrors#initialize` now takes its input array under the `exceptions:` keyword instead of `errors:`. The kwarg accepts a mix of `Grape::Exceptions::Validation` and `Grape::Exceptions::ValidationArrayErrors` instances; `ValidationArrayErrors` wrappers are flattened internally via `flat_map(&:errors)`. The `errors` reader on the constructed instance (the grouped `{params => [Validation, ...]}` Hash) is unchanged.
