With a focus on seamless **integration**, enhanced capabilities, and improved **user experience**, this release brings a plethora of features to help you build **robust** and innovative applications. Let's delve into the highlights: ## 🆔 OpenIddict Integration: Enhancing Authentication and Authorization ![OpenIddict](https://aspnetzero.com/images/blog/openiddict-core.png) As you may know, ASP.NET Zero **ended** using the **Identity Server** as the default authentication and authorization provider in v12.0. However, we've received **feedback** from our customers that they **need to use** a authentication and authorization **provider** that is **lightweight** and easier to configure. That's why we've decided to integrate **OpenIddict**, a simple yet powerful **OpenID Connect** server, into ASP.NET Zero. Incorporating OpenIddict into ASP.NET Zero v12.3 marks a significant step forward in authentication and authorization. With **OpenIddict** integration, now you can use your ASP.NET Zero application as an authentication server. This allows you to easily implement **OAuth 2.0** and **OpenID Connect protocols**. For more information about OpenIddict, you can check its [GitHub repository](https://github.com/openiddict/openiddict-core) and its [documentation](https://documentation.openiddict.com/). ## 🌅 Upgrade to Angular 16: Embracing the Latest Technologies ![Angular 16](https://aspnetzero.com/images/blog/angular16.webp) Innovation never stops, and neither does ASP.NET Zero. With the **upgrade** to **Angular 16**, you gain access to cutting-edge features and performance enhancements. This transition underscores our commitment to staying current with **technology trends** and providing you with a **robust** development environment. ## 🎆 Upgrade to ABP 8.3: Harnessing the Power of the Latest ASP.NET Boilerplate ABP 8.3 introduces a host of **enhancements**, including improved **performance**, enhanced **security**, and streamlined development. Notably, **Castle.Windsor** has been updated to 6.0 which was waited for a long time. Leverage these updates to harness the latest technologies and capabilities for crafting exceptional applications. ## 🏹 Power Tools: Loading Entity Data from Oracle Databases We're excited to announce a **new capability** in Power Tools – the ability to **load entity** data from **Oracle** databases. This enhancement streamlines data management, making it seamless to connect and retrieve information from Oracle databases. You can now easily **create** your entities and **CRUD pages** from Oracle databases, **saving** you time and effort. This feature allows you to automatically generate CRUD pages in ASP.NET Zero for your legacy application which uses an Oracle database. ## ⛄️ Power Tools: Overriding Application Services with Partial Classes ASP.NET Zero v12.3 introduces a new feature in Power Tools that allows you to **override** application services with **partial classes**. This capability enables you to **extend** the **functionality** of **application services** without modifying the original code automatically generated by ASP.NET Zero Power Tools. You can now add your **custom code** to the partial class, which will be **merged** with the **original** class at runtime. So, your custom changes will not be overwritten when you regenerate any entity using ASP.NET Zero Power Tools. ## 🏰 Logo Management: Logo Icon Upload ![Logo Icon Upload](https://aspnetzero.com/images/blog/upload-logo-icon-aspnetzero.png) In response to user demand, ASP.NET Zero v12.3 introduces **support** for logo icon upload. This **feature** allows you to upload your **logo icon** and display it in the top left corner of the application. You can also upload a logo icon for **each tenant**, which will be displayed in the top left corner of the tenant's page. That feature supports both **light** and **dark** themes. ## 🍀 New Blog Post: Elsa Integration with AspNet Zero Angular UI ![Elsa](https://aspnetzero.com/images/blog/integrating-elsa-with-asp.net-zero-angular.png) We published a new blog post to explain integration of Elsa worflow library with AspNet Zero Angular UI.

ASP.NET Zero v12.3 acknowledges and addresses landscape tablet issues, ensuring that your applications maintain their **functionality** and user-friendliness across various device orientations. We believe in **delivering** a consistent experience to your users, **regardless** of how they access your application. ## 🙏 Conclusion With ASP.NET Zero v12.3, we've raised the bar yet again.
