I am pleased to announce NNCP 7.1.0 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:

* Multicasting areas feature appeared. Implemented merely by an
additional plain packet type with "nncp-toss", "nncp-file" and
"nncp-exec" commands modification.

* Fixed workability of "nncp-file" and "nncp-exec" commands, that use
temporary file (stdin and "-use-tmp").

* Fixed disappearing bad return code in "nncp-exec" command.

* Fixed invalid ".hdr" generation when transitional packets are used.

* "-all" option appeared in "nncp-rm" command, applying to all the
nodes at once.

* "-cycle" option appeared in "nncp-check" command, looping the check
in infinite cycle.

* "nncp-rm" command can take node alias name.

* "nncp-pkt" can parse ".hdr" files.
