New features and functionality in Wowza Streaming Engine 4.8.19
Wowza Streaming Engine is a robust, customizable, and scalable media server software that powers reliable streaming of high-quality video and audio to any device, anywhere. Wowza Streaming Engine 4.8.19 contains several enhancements and fixes that help to improve the functionality of the media server software.
SHA2 Authentication
With Wowza Streaming Engine 4.8.19 we've added support for sha256 encryption for digest and digestfile methods of authentication.

Installation and update considerations for Wowza Streaming Engine 4.8.19
If you are updating to Wowza Streaming Engine 4.8.19 from a base installation of Wowza Streaming Engine 4.8.17 or earlier, before you update, you need to install a supported version of Java, such as Java 11-12 or the OpenJDK Java SE JRE 11.0.2 installed with Wowza Streaming Engine 4.8.18 (available from the Downloads tab of My Account). Then instruct Wowza Streaming Engine to use that version of Java according to the instructions in Manually install and troubleshoot Java on Wowza Streaming Engine.
When using the Wowza Streaming Engine 4.8.18 installer to install a new instance of Wowza Streaming Engine on Windows, you may need to install additional dependencies in order to ingest SRT MediaCaster streams or use the generic SRT stream targets destination to publish an SRT stream. To address this, install the latest version of the Microsoft Visual C++ Redistributable for Visual Studio appropriate to your operating system.
