I am pleased to announce NNCP 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 networks
for fire-and-forget secure reliable files, file requests and Internet
mail 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:

* *Incompatible* encrypted packet format changes. Older versions are not
* nncp-bundle command can either create stream of encrypted packets, or
  digest it. It is useful when dealing with stdin/stdout based
  transmission methods (like writing to CD-ROM without intermediate
  prepared ISO image and working with tape drives).
* nncp-toss is able to create .seen files preventing duplicate packets
* Single background checksum verifier worker is allowed in nncp-call.
  This is helpful when thousands of small inbound packets could create
  many goroutines.
* Ability to override path to spool directory and logfile through either
  command line argument, or environment variable.
* nncp-rm is able to delete outbound/inbound, .seen, .part, .lock and
  temporary files.
