Modernization: Support for .NET Framework 4.6.2 and .NET 6.0 and above

Moving forward, our .NET-based products will exclusively support .NET Framework versions 4.6.2 and above and .NET versions 6.0 and above. By targeting .NET Framework 4.6.2 and .NET 6.0, we are aligning ourselves with Microsoft's lowest-supported framework versions for .NET Framework and .NET, respectively. This enables compatibility with Microsoft’s ongoing updates and support, allowing us to deliver a more robust and secure experience to you.

Telerik UI for WPF: Smart AI Components Demos

With 2024 Q2 release, we’re introducing experimental Smart (AI) components in Telerik UI for WPF. As a first stage we’ve crafted two ready to use, AI integration demos:

• Smart Spreadsheet – This example shows how to integrate the Azure OpenAI services with the WPF Spreadsheet and use the custom AIFunction to automatically get the cells result
• Smart Rich Text Box - This example shows how to integrate the Azure OpenAI services with the WPF RichTextBox. Typing in the document will initiate a call to OpenAI services, which will then append the received results into the document.

Multiple Document Processing Libraries (DPL) Improvements

• Font subset embedding in PDF for .NET 6+ : The PDF library now supports controlling if the whole TrueType font or only a subset of the used characters gets embedded in the resulting document. This makes the document portable and at the same time with optimal file size. 
• OTF font file format support: Our PDF library now supports OpenType font format (OTF) which is widely used and combines the features of PostScript and TrueType font formats. 
• New online demo application: This dedicated DPL asset exposes many common scenarios where the libraries can help along with full code snippets. 
• All document processing libraries now only support .NET Framework 4.6.2 and above, and .NET 6 and above.
   

New WPF Control: DateRangePicker

With 2024 Q1 the WPF suite continues to evolve and improve with the introduction of the DateRangePicker control. It is a scheduling control that allows users to easily select a range of dates in your application. This is useful for scenarios such as booking hotels, showing graphs with sales data in specific ranges and more.

The DateRangePicker comes with a set of built-in features like:

• Culture settings
• Read-only support
• Allowed selection range
• Blackout dates
• Customizable input element
• Customizable calendars
• And more!

See the WPF DateRangePicker documentation: Overview

PDF Processing: Embedding File Streams

With the 2024 Q1 the PDF Processing allows embedding file streams into documents. Therefore, the content of the referenced files is embedded directly within the body of the PDF file.

See the PDF Processing documentation: Embedded File Streams

PDF Processing: Support for Embedding ZUGFeRD Invoices

Another PDF Processing enhancement is the support for adding embedded ZUGFeRD invoices into documents. This invoice consists of two formats – PDF and XML and it is a hybrid file, which has a visual component with the PDF and a data-based offshoot for further, automated processing with the XML.

Zip Library: Strong AES Encryption Algorithm

We’ve introduced a new encryption algorithm in the Zip Library – AES encryption. It is best suited to secure sensitive information, such as credit card numbers, passwords, and personal data. You can read and extract AES-protected archives with ease.
