* 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.
