I am pleased to announce NNCP 0.7 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 and air-gapped
computers support. But online TCP daemon with full-duplex resumable data
transmission exists.

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

The main improvements for that release are:

* Ability to feed nncp-file from stdin, that uses an encrypted temporary
  file for that.
* Chunked files transmission appeared with corresponding nncp-reass
  command and freqchunked configuration file entry. Useful for
  transferring big files over small storage devices.
* freqminsize configuration file option, analogue to -minsize one.
* nncp-xfer's -force option is renamed to -mkdir for clarity.
* -minsize option is specified in KiBs, not bytes, for convenience.
* nncp-newcfg command is renamed to nncp-cfgnew, and nncp-mincfg to
  nncp-cfgmin -- now they have common prefix and are grouped together
  for convenience.
* nncp-cfgenc command appeared, allowing configuration file
  encryption/decryption, for keeping it safe without any either OpenPGP
  or similar tools usage.
* Cryptographic libraries (dependencies) are updated.
