+- All Hash-related methods now return String keys instead of Symbol keys.
+    This affects all users, but you can use `deep_symbolize_keys` in Rails environment if you prefer Symbol keys, or `with_indifferent_access` to support both String and Symbol keys.
+    Some DSLs that take key argument such as `on_nil` and `on_error`, are also affected.
 - Remove deprecated methods: `Resource#to_hash`, `Resource.ignoring`, `Alba.on_nil`, `Alba.on_error`, `Alba.enable_root_key_transformation!` and `Alba.disable_root_key_transformation!`
 - If using `transform_keys`, the default inflector is no longer set by default [d02245c8](https://github.com/okuramasafumi/alba/commit/d02245c87e9df303cb20e354a81e5457ea460bdd#diff-ecd8c835d2390b8cb89e7ff75e599f0c15cdbe18c30981d6090f4a515566686f)
     To retain this functionality in Rails, add an initializer with the following:
     `Alba.enable_inference!(with: :active_support)`
