Update your current installation
Sign in to your Account Management page using your Wowza account and then check the My Downloads tab to get a production build update for your installed Wowza Streaming Engine software.
When I log in to My Account and go to the My Downloads tab, the only version available is 4.3.0.02. Version 4.3.0.02 seems to be a development build:
Between stable, production releases, Wowza™ produces development builds periodically in the form of updates. This allows you to try the latest releases of Wowza media server software to test and give feedback, and to get early access to new features. For more information about the latest Development updates, see Development Builds.
Note: Development builds are not official releases and may not be stable.
Wowza Streaming Engine 4.3.0
The latest Wowza media server software development build is Wowza Streaming Engine 4.3.0.02 build 17246 released on December 16, 2015.
I figure that I should be using version 4.3.0.02 (since that is the only version available in the My Downloads tab) but why does the documentation says that it is a development build?
