**Wowza Streaming Engine 4.8.12 is available today. Here’s what’s new:**

**Error-free Frames:**  
In an effort to prevent damaged video from reaching your viewers, we’ve added the ability to replace corrupt video files with error-free frames. Using the EnforceStrictDecodeSuccess property in a Transcoder template, you can replace corrupt frames with error-free frames for H.264 video and Beamr decoding. This will allow you to optimize media processing through a balance of reliability and quality.

**Deprecation of Adobe HDS and Microsoft Smooth Streaming.**  
With the end-of-life of Adobe Flash Player and Microsoft Smooth Streaming, Wowza will no longer be supporting Adobe HDS and Smooth Streaming.

- By default, Adobe HDS and Smooth Streaming are disabled in new applications created​.
- Applications created in earlier versions of Wowza Streaming Engine are unchanged after upgrading to Wowza Streaming Engine 4.8.12​.  
  

**NOTE: There are a total of 16 bug fixes in this release** , so please be sure to check the full list in the [4.8.12 release notes](https://www.wowza.com/docs/wowza-streaming-engine-4-8-12-release-notes).
