@node Release 3.3
@section Release 3.3
@itemize
@item
@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
if @file{.seen} exists and treat it like file was already downloaded.
Possibly it was transferred out-of-bound and remote side needs to be
notifier about that.
@item
If higher priority packet is spooled, then @command{nncp-daemon} will
queue its sending first, interrupting lower priority transmissions.
@item
Simple packet rate limiter added to online-related tools
(@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
@item
Ability to specify niceness with symbolic notation:
@verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, итд.
@item
Changed default niceness levels:
for @command{nncp-exec} from 64 to 96,
for @command{nncp-freq} from 64 to 160,
for @command{nncp-file} from 196 to 224.
@end itemize

@node Release 3.2
@section Release 3.2
@itemize
@item
@strong{Incompatible} @emph{bundle} archive format changes and
@command{nncp-bundle} workability with Go 1.10+. Bundles must be
valid tar archives, but Go 1.9 made them invalid because of long paths
inside. NNCP accidentally was dependant on that bug. Explicit adding of
@file{NNCP/} directory in archive restores workability with valid tar
archives.

@node Release 3.1
@section Release 3.1
@itemize
@item
Ability to disable relaying at all using @verb{|-via -|} command line option.
@end itemize

@node Release 3.0
@section Release 3.0
@itemize
@item
@strong{Incompatible} plain packet format changes. Older versions are
not supported.
@item
Ability to queue remote command execution, by configuring @option{exec}
option in configuration file and using @command{nncp-exec} command:
    @itemize
    @item
    @command{nncp-mail} command is replaced with more flexible
    @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
    you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
    @item
    @option{sendmail} configuration file option is replaced with
    @option{exec}. @verb{|sendmail: [...]|} must be replaced with
    @verb{|exec: sendmail: [...]|}.
    @end itemize
@item
Ability to override @option{via} configuration option for destination
node via @option{-via} command line option for following commands:
@command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
@item
Chunked files, having size less than specified chunk size, will be sent
as an ordinary single file.
@item
Exec commands are invoked with additional @env{NNCP_NICE} and
@env{NNCP_SELF} environment variables.
@item
Files, that are sent as a reply to freq, have niceness level taken from
the freq packet. You can set desired niceness during @command{nncp-freq}
invocation using @option{-replynice} option.
@item
@command{nncp-toss} command can ignore specified packet types during
processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
@option{-notrns}.
@item
@command{nncp-file} command uses
@option{FreqMinSize}/@option{FreqChunked} conifiguration file options
for @option{-minsize}/@option{-chunked} by default. You can turn this
off by specifying zero value.

@node Release 2.0
@section Release 2.0
@itemize
@item
@strong{Incompatible} encrypted/eblob packet format changes. Older
versions are not supported.
@item
Twofish encryption algorithm is replaced with ChaCha20. It is much more
faster. One cryptographic primitive less.
@item
HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
another cryptographic primitive less (assuming that BLAKE2X is nearly
identical to BLAKE2).
@end itemize

@node Release 1.0
@section Release 1.0
@itemize
@item
@strong{Incompatible} encrypted packet format changes. Older versions
are not supported.
@item
@command{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).
@item
@command{nncp-toss} is able to create @file{.seen} files preventing
duplicate packets receiving.
@item
Single background checksum verifier worker is allowed in
@command{nncp-call}. This is helpful when thousands of small inbound
packets could create many goroutines.
@item
Ability to override path to spool directory and logfile through either
command line argument, or environment variable.
@item
@command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
@file{.part}, @file{.lock} and temporary files.

@node Release 0.12
@section Release 0.12
@itemize
@item
Sendmail command is called with @env{NNCP_SENDER} environment variable.
@end itemize

@node Release 0.11
@section Release 0.11
@itemize
@item
@command{nncp-stat}'s command output is sorted by node name.
@end itemize

@node Release 0.10
@section Release 0.10
@itemize
@item
@command{nncp-freq}'s @file{DST} argument is optional now. Last
@file{SRC} path's element will be used by default.
@end itemize

@node Release 0.9
@section Release 0.9
@itemize
@item
Fix @option{-rx}/@option{-tx} arguments processing in
@command{nncp-call} command. They were ignored.
@end itemize

@node Release 0.8
@section Release 0.8
@itemize
@item
Little bugfix in @command{nncp-file} command, where @option{-minsize}
option for unchunked transfer was not in KiBs, but in bytes.
@end itemize

@node Release 0.7
@section Release 0.7
@itemize
@item
Ability to feed @command{nncp-file} from stdin, that uses an encrypted
temporary file for that.

@item
Chunked files transmission appeared with corresponding
@command{nncp-reass} command and @option{freqchunked} configuration file
entry. Useful for transferring big files over small storage devices.

@item
@option{freqminsize} configuration file option, analogue to
@option{-minsize} one.

@item
@command{nncp-xfer}'s @option{-force} option is renamed to
@option{-mkdir} for clarity.

@item
@option{-minsize} option is specified in KiBs, not bytes, for
convenience.

@item
@command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
common prefix and are grouped together for convenience.

@item
@command{nncp-cfgenc} command appeared, allowing configuration file
encryption/decryption, for keeping it safe without any either OpenPGP or
similar tools usage.

@item
Cryptographic libraries (dependencies) are updated.
@end itemize

@node Release 0.6
@section Release 0.6
@itemize
@item Small @command{nncp-rm} command appeared.
@item Cryptographic libraries (dependencies) are updated.
@end itemize

@node Release 0.5
@section Release 0.5
@itemize
@item Trivial small fix in default niceness level of @command{nncp-file}
and @command{nncp-freq} commands.
@end itemize

@node Release 0.4
@section Release 0.4
@itemize
@item Small fix in @command{nncp-call}, @command{nncp-caller},
@command{nncp-daemon}: they can segmentation fail sometimes (no data is
lost).
@item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
shorter and more convenient to use.
@item @command{nncp-mincfg} command appeared: helper allowing to create
minimalistic stripped down configuration file without private keys,
that is useful during @command{nncp-xfer} usage.
@end itemize

@node Release 0.3
@section Release 0.3
Fixed compatibility with Go 1.6.

@node Release 0.2
@section Release 0.2
@itemize
@item @strong{Incompatible} packet's format change (magic number is
changed too): size field is encrypted and is not send in plaintext
anymore.
@item @option{-minsize} option gives ability to automatically pad
outgoing packets to specified minimal size.
@item @command{nncp-daemon} and
@command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
packets appearance in the background while connected. Remote side is
immediately notified.
@item @option{-onlinedeadline} option gives ability to configure timeout
of inactivity of online connection, when it could be disconnected. It
could be used to keep connection alive for a long time.
@item @option{-maxonlinetime} option gives ability to set maximal
allowable online connection aliveness time.
@item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
@item @command{nncp-pkt} command can decompress the data.
