 # ABP Commercial 4.3 RC Has Been Published
 
+ABP Commercial version 4.3 RC (Release Candidate) has been published alongside ABP Framework 4.3. RC (TODO: link). I will introduce the new features in this blog post. Here, a list of highlights for this release;
+
+* The **microservice starter template** is getting more mature. We've also added a **service template** to easily add new microservices to the solution.
+* New option for the application starter template to have a **separate database schema for tenant databases**.
+* New **Forms** module to create surveys
+* **Enable/disable modules** per edition/tenant.
+* **Lepton theme** and **Account module**'s source codes are available with the Team License too.
+
+Here, some other features already covered in the ABP Framework announcement, but worth to mention here since they are also implemented for the ABP Commercial;
+
+* **Blazor UI server-side** support
+
+* **Email setting** management UI
+* **Module extensibility** system is now available for the **Blazor UI** too.
+
+> This post doesn't cover the features and changes done on the ABP Framework side. Please also see the **ABP Framework 4.3. RC blog post** (TODO: link).
+
+## The Migration Guide
+
+**This upgrade requires some manual work documented in [the migration guide](https://docs.abp.io/en/commercial/4.3/migration-guides/v4_3).** Please read the guide carefully.

+Blazor Server applications are actually mixed applications; You can mix the server-side MVC / Razor Pages with the Blazor SPA. This brings an interesting opportunity: MVC / Razor Pages modules can work seamlessly in the Blazor Server applications. For example, CMS Kit module has no Blazor UI yet, but you can use its MVC UI inside your Blazor Server application.

+> Blazor Server UI has a `--tiered` option just [like](https://docs.abp.io/en/abp/latest/Startup-Templates/Application#tiered-structure) the MVC / Razor Pages UI. This can be used to separate HTTP API server from UI server (UI application doesn't directly connect to the database).

 ### Angular UI Resource Owner Password Flow
 
 Login page was removed from the Angular UI in previous versions, because Authorization Code flow is the recommended approach for SPAs. However, it requires to redirect user to the authentication server, login there and come back to the application. We got many feedback because this brings overhead for simple applications.
