I am pleased to announce NNCP 6.5.0 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.

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.

------------------------ >8 ------------------------

The main improvements for that release are:

* Fixed segfault in "nncp-daemon" when SP handshake did not succeed.
* Fixed possible bad return code ignoring in automatic tosser.
* Fixed race during file descriptors closing when online protocol
  call is finished, that could lead to write error of received packet
* Kill all packet transmission progress bars in "nncp-daemon",
  "nncp-call" and "nncp-caller" when call is finished.
