How do I update my version of FreeRADIUS to a pre-release testing version for my distribution?
Software updates appear in repositories (i.e. repos) for specfic distributions. Each distribution contains two channels, testing and stable. Normally new package versions are placed in the testing channel for a period of time before being moved to stable. By default the yum configuration only enables the stable channel. If you want a package from the testing channel you have to tell yum to enable the testing channel when you run it. So you would use the yum package updating tool but override it’s repository selection.
