I am pleased to announce NNCP 8.12.0 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:

* Combine all executables in single 'nncp'.  You should symlink all
  'nncp-*' commands to it.

* Prevent path traversal during freqing and file saving.  Previously
  malicious paths in packets may request or overwrite file outside
  freq or incoming directories.
  Thanks to Eugene Medvedev for finding and fixing that serious issue!
