Wowza Streaming Engine software releases
Wowza Streaming Engine currently has the following types of software updates:
- Production – Long-term supported builds with new features and bug fixes and full regression and performance testing for use in production environments.
- Patch – Between production releases, Wowza occasionally provides patch releases to fix bugs or regressions in the latest production release, which can be deployed in production environments for long-term stability. Patches undergo varying degrees of regression and performance testing, but generally not as much as a long-term supported production build.
- Beta – For early access to new features and improvements being developed, Wowza also provides betas between production releases. Although the improvements and enhancements have been tested by QA, full regression testing and performance testing hasn't been performed on beta builds, and they should only be used in testing environments. Support for beta builds is fully available, but there is no guarantee of hotfixes.
