 * Moved pattern resolution logic from `DataCatalog` to a separate component - `CatalogConfigResolver`. Updated `DataCatalog` to use `CatalogConfigResolver` internally.
 * Made packaged Kedro projects return `session.run()` output to be used when running it in the interactive environment.
 * Enhanced `OmegaConfigLoader` configuration validation to detect duplicate keys at all parameter levels, ensuring comprehensive nested key checking.
+
 ## Bug fixes and other changes
 * Fixed bug where using dataset factories breaks with `ThreadRunner`.
 * Fixed a bug where `SharedMemoryDataset.exists` would not call the underlying `MemoryDataset`.
 * Fixed template projects example tests.
-* Made credentials loading consistent between `KedroContext._get_catalog()` and `resolve_patterns` so that both us
-e `_get_config_credentials()`
+* Made credentials loading consistent between `KedroContext._get_catalog()` and `resolve_patterns` so that both use `_get_config_credentials()`
+* Allow runtime parameters to be wrapped in a list.
 
 ## Breaking changes to the API
 * Removed `ShelveStore` to address a security vulnerability.
