+@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.

+@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).

+@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.

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

+@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.

+Cryptographic libraries (dependencies) are updated.

+@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.
