 ### Changed
 
+- Implemented partial class model declarations. [4894](https://github.com/microsoft/kiota/issues/4894)
+- Fixed a bug where the Go file names were too long
 - Fixes bug with model names in Go generated from camel case namespace. [https://github.com/microsoftgraph/msgraph-sdk-go/issues/721]
 - Plugins OpenAPI extensions are only added when generating plugins to reduce the risk of parsing errors. [#4834](https://github.com/microsoft/kiota/issues/4834)
 - TypeScript imports are now using ES6 imports with the .js extension.

 - Ensures descriptions are not empty in sliced OpenApi file when generating a plugin.
 - Plugins do not emit parameters anymore. [#4841](https://github.com/microsoft/kiota/issues/4841)
 - References to C# types generated by kiota are prefixed with `global::` to avoid name collisions. [#4796](https://github.com/microsoft/kiota/issues/4796)
+- Ensures HashSet properties in `KiotaLock` maintain IgnoreCase comparer across runs [#4916](https://github.com/microsoft/kiota/issues/4916)
+- Dropped `client base url set to` message when generating plugins. [#4905](https://github.com/microsoft/kiota/issues/4905)
