Telerik 修訂對 .NET 的支援

11月 17, 2023
從 2024 年開始，Telerik .NET 產品將專門支援 .NET Framework 4.6.2+ 和 .NET 6.0+。

What is changing?

As part of Telerik's commitment to providing cutting-edge solutions at the highest security and performance standards, it has announced an important update. Starting with the upcoming releases, its .NET-based products (listed at the end of this article) will exclusively support .NET Framework 4.6.2 and above, and .NET 6.0 and above. The last release supporting older framework versions is scheduled for the end of January 2024. After that, Telerik will provide one full year of support services for that release to ensure a smooth transition.

Which versions of .NET are affected?

Support for the following .NET versions is ending:

  • .NET 5.0
  • .NET Core 3.1
  • .NET Core 3.0
  • .NET Framework 4.6.1
  • .NET Framework 4.6
  • .NET Framework 4.5.2
  • .NET Framework 4.5.1
  • .NET Framework 4.5
  • .NET Framework 4.0

Why is this changing?

By targeting .NET Framework 4.6.2 and .NET 6.0, Telerik is aligning with Microsoft’s lowest-supported framework versions for .NET Framework and .NET, respectively. This enables compatibility with Microsoft’s ongoing updates and support to deliver a more robust and secure experience to you. A shift to modern framework versions brings a host of benefits including:

  • Enhanced Security: Modern frameworks come equipped with the latest security features, protecting your applications and data against evolving threats.
  • Security Certification Compliance: Using actively supported frameworks and certified tools is a prerequisite to certifying for the generally recognized security compliance certificates, e.g., SAMM Level 2 and above.
  • Improved Performance: Embracing the latest technologies allows our products to leverage performance enhancements, ensuring a faster and more responsive user experience.
  • Future-Proofing: Staying up to date with the latest framework versions allows your applications to remain compatible with future updates, preserving their longevity and reducing the need for frequent migrations.

將 AV1 硬體編碼 + 解碼添加到您的應用程式

11月 13, 2023
MPlatform SDK V2.8 添加對 NVIDIA 硬體編碼/解碼的支援，允許您使用高解析度 #AV1 流。

The MPlatform SDK is a professional multimedia software development kit that supports native C#, VB.NET, VB6, Visual C++, and Embarcadero Delphi, allowing you to create broadcast automation, ingest, and video mixing applications.

MPlatform SDK v2.8 adds support for AV1 NVIDIA hardware encoding and decoding. AV1 is a next-generation video codec that offers superior compression efficiency and image quality compared to older codecs like H.264 and HEVC. NVIDIA GPU hardware encoding is much faster than CPU-based encoding. Hardware decoding allows users to play back AV1 video with lower CPU usage and power consumption. The addition of hardware encoding/decoding to the MPlatform SDK makes working with high-resolution AV1 streams more efficient and practical.
