RELEASE NOTES:

security-libs/java.security:

    JDK-8245654: Added Certigna(Dhimyotis) CA Certificate

      The following root certificate has been added to the cacerts truststore: ``` + Certigna
      (Dhimyotis)   + certignaca     DN: CN=Certigna, O=Dhimyotis, C=FR ```

core-libs/java.io:

    JDK-8208077: `File::listRoots` Changed to Return All Available Drives on Windows

      The behavior of the method `java.io.File.listRoots()` on Microsoft Windows has changed in this
      release so that the returned array includes a `File` object for all available disk drives.
      This differs from the behavior in JDK 10 to JDK 20, where this method filtered out disk drives
      that were not accessible or did not have media present. This change avoids performance issues
      observed in the previous releases and also ensures that the method is consistent with the root
      directories in the iteration returned by `FileSystem.getDefault().getRootDirectories()`.
