+* [OpenIddict](https://github.com/openiddict/openiddict-core/tree/4.7.0) library has been upgraded to **v4.7.0**. See [#17334](https://github.com/abpframework/abp/pull/17334) for more info.
+* ABP v7.4 introduces the `Volo.Abp.Maui.Client` package, which is used by the MAUI mobile application in ABP Commercial. See [#17201](https://github.com/abpframework/abp/pull/17201) for more info.
+* In this version, the `AbpAspNetCoreIntegratedTestBase` class gets a generic type parameter, which expect either a startup class or an ABP module class. This allows us to use configurations from an ABP module or old-style ASP.NET Core Startup class in a test application class and this simplifies the test application project. See [#17039](https://github.com/abpframework/abp/pull/17039) for more info.
