v3.0.0 Release Notes

### Description

  Configuration
    In this release, no new configuration entries have been added, nor have any other changes occurred with respect to the configuration.

    A full list of supported configuration entries is given in this service's man page.

  Logging
    In this release, no changes have occurred with respect to the logging mechanism employed by Norm, which logs diagnostic information using a separate `Logger` for each type of information logged. The name of each logger is a dot-separated concatenation of the implementation package name, `org.apache.river.norm`, with a descriptive string. A description of each logger used by this service, as well as what information is logged to which logger, and at what logging level, is given in this service's man page.

  Bug Fixes of Interest
    A number of bugs have been addressed in this release of Norm. What follows is a description of those bugs that might be of interest:

  4965775: Norm threads should guard against lost interrupts
    Thread subclasses in Norm that use logging and do not override the `Thread.interrupt` method to set an "interrupted" field are susceptable to lost interrupts. This problem can occur because `java.util.logging` swallows internal `InterruptedIOExceptions` without setting the receiving thread's interrupted status, effectively forgetting the interrupt. The end result is that some of Norm's threads could loop endlessly instead of terminating, causing Norm shutdowns to hang.

    This bug has been fixed.
