### Release 7.7.0 ¶

- Experimental `kqueue` and `inotify` based notifications support about spool directory changes, for reducing their often reading overhead.
- `.seen` and `.hdr` files moved to `seen/` and `hdr/` subdirectories, for faster scanning of spool directories. Current files migration required:

      $ find $NNCPSPOOL -type f -name "*.hdr" -exec rm {} +

      $ find $NNCPSPOOL -type d -name rx | while read rx ; do
          cd $rx
          mkdir -p seen
          find . -type f -name "*.seen" | while read fn ; do
              mv $fn seen/${fn%.seen}
          done
      done

      $ find $NNCPSPOOL -type d -name area | while read area ; do
          find $area -type f -name "*.seen" | while read fn ; do
              mv $fn ${fn%.seen}
          done
      done
