I am pleased to announce NNCP 7.7.0 release availability!

NNCP (Node to Node copy) is a collection of utilities simplifying
secure store-and-forward files and mail exchanging.

This utilities are intended to help build up small size (dozens of
nodes) ad-hoc friend-to-friend (F2F) statically routed darknet
delay-tolerant networks for fire-and-forget secure reliable files, file
requests, Internet mail and commands transmission. All packets are
integrity checked, end-to-end encrypted (E2EE), explicitly authenticated
by known participants public keys. Onion encryption is applied to
relayed packets. Each node acts both as a client and server, can use
push and poll behaviour model. Also there is multicasting areas support.

Out-of-box offline sneakernet/floppynet, dead drops, sequential and
append-only CD-ROM/tape storages, air-gapped computers support. But
online TCP daemon with full-duplex resumable data transmission exists.

The main improvements for that release are:

* Experimental "kqueue" and "inotify" based notifications support
  about spool directory changes, for reducing their often reading

* ".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}

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