Release 3.0 (NNCP)

Incompatible plain packet format changes. Older versions are not supported.
Ability to queue remote command execution, by configuring exec option in configuration file and using nncp-exec command:
- nncp-mail command is replaced with more flexible nncp-exec. Instead of nncp-mail NODE RECIPIENT you must use nncp-exec NODE sendmail RECIPIENT.
- sendmail configuration file option is replaced with exec. sendmail: […] must be replaced with exec: sendmail: […].
Ability to override via configuration option for destination node via -via command line option for following commands: nncp-file, nncp-freq, nncp-exec.
Chunked files, having size less than specified chunk size, will be sent as an ordinary single file.
Exec commands are invoked with additional $NNCP_NICE and $NNCP_SELF environment variables.
Files, that are sent as a reply to freq, have niceness level taken from the freq packet. You can set desired niceness during nncp-freq invocation using -replynice option.
nncp-toss command can ignore specified packet types during processing: -nofile, -nofreq, -noexec, -notrns.
nncp-file command uses FreqMinSize/FreqChunked configuration file options for -minsize/-chunked by default. You can turn this off by specifying zero value.
