13 @command{nncp-daemon}, @command{nncp-caller}, @command{nncp-call}
14 commands have @option{-autotoss-gen-ack} option. They automatically
15 generate ACK packets and store corresponding @file{spool/tx/ack/}
16 references to them, to be able to remove them after the transfer.
19 @code{autotoss-gen-ack} appeared in call configuration.
20 @code{ack} section appeared in neighbour configuration.
23 @command{nncp-rm} command has @option{-ack} option to remove packets
24 referenced by stored @file{spool/tx/ack/} files generated during tossing.
27 Get rid of @command{redo} build system during installation, as there are
28 virtually none dependencies, just only compilation of the Go code.

113 @command{nncp-ack} does not acknowledge ACK-packets, preventing an
114 endless loop of ACKs.
117 @command{nncp-ack} previously did not remove corresponding @file{hdr/} files.
120 @command{nncp-rm} now takes list of packet from @code{stdin} when
121 @option{-pkt} option is used.
124 @command{nncp-ack} now generates list of ACK packets it created, that
125 could be used as an input to @command{nncp-rm} to remove outbound ACK

135 @command{nncp-xfer} checks if locally copied packet's checksum differs
136 from the source's one.
139 @command{nncp-call} has bad return code if its queues contain unfinished jobs.
142 @command{nncp-ack} command appeared, that sends explicit packet receipt
143 acknowledgement (ACK packet). That acknowledgement deletes referenced
144 packet from the outbound spool.
147 Ability to turn @code{fsync} operation off using @env{$NNCPNOSYNC=1}
148 environment variable.
151 Added various indices in documentation, that should help searching in it.

181 Multicast related interface names (@code{mcd-listen} and @code{mcd-send}
182 configuration options) are now regular expressions. By default
183 @command{nncp-cfgnew} uncomments them now with @code{.*} interface name.
186 @command{nncp-call} command has @option{-mcd-wait} option to wait for
187 multicast packet about node's address.

200 Fixed building issues on 32-bit systems.
205 @section Release 8.2.0
209 Yggdrasil uses pure-Go IPv6+TCP network stack, instead of naked μTP
210 transport protocol, making it able to work as an ordinary TCP server
211 inside overlay network.
214 Yggdrasil's @code{prv;bind1,bind2;pub@dots{}}-like configuration strings are
215 replaced with URL-like ones (@code{yggdrasils://PRV?bind=BIND1&bind=BIND2&pub=PUB}).
218 Ability to pass multicast-related parameters to Yggdrasil configuration.
221 @command{nncp-daemon} is able to listen on both TCP and Yggdrasil-driven
222 sockets simultaneously.
225 @command{nncp-daemon}'s listening on peering endpoint socket is optional
226 -- you can be reached through the peers.
231 @section Release 8.1.0
235 @command{nncp-cfgdir} does not require @code{self} section existence in

248 Fixed sending ability to areas.
253 @section Release 8.0.1
257 Fixed incorrect @code{freq.chunked} value calculation. If it was missed,
258 then chunked transfer mode was forcefully turned on anyway.
261 Fixed incorrect full file's size calculation in @file{.nncp.meta}.
266 @section Release 8.0.0
270 @strong{Incompatible} encrypted packet format change: payload and pad
271 sizes are sent in-bound in the encrypted stream. That gives ability to
272 streamingly create encrypted packets, without knowing sizes in advance,
273 without creating temporary file or buffer data in memory.
276 Proper encrypted packet padding verification is done now. This is not
277 critical issue, but previously neither padding value, nor its size were
278 authenticated, giving ability to iteratively strip trailing bytes and
279 determine payload's size by observing the reaction of the encrypted
283 @command{nncp-exec} loses its @option{-use-tmp} option, because of
284 streaming-compatible encrypted packets format.
287 @command{nncp-file} and @command{nncp-exec} commands have
288 @option{-maxsize} option, limiting maximal resulting encrypted packet's
289 maximal size (returning error if it is exceeded). Could be useful,
290 because no payload size could be known in advance.
295 @section Release 7.7.0
299 Experimental @code{kqueue} and @code{inotify} based notifications
300 support about spool directory changes, for reducing their often reading
304 @file{.seen} and @file{.hdr} files moved to @file{seen/} and @file{hdr/}
305 subdirectories, for faster scanning of spool directories.
306 Current files migration required:
309 $ find $NNCPSPOOL -type f -name "*.hdr" -exec rm @{@} +
311 $ find $NNCPSPOOL -type d -name rx | while read rx ; do
314 find . -type f -name "*.seen" | while read fn ; do

333 Logging may be done to specified opened file descriptor
334 (@env{$NNCPLOG=FD:5} for example).
335 That is friendly to use under @command{daemontools}.
338 Added additional checks of public keys existence in configuration file,
339 preventing some commands from failing.
344 @section Release 7.5.1
348 NNCP builds on NetBSD.
353 @section Release 7.5.0
357 @command{nncp-daemon} is compatible with UCSPI-TCP interface, so log
358 will contain remote side's address (when running under appropriate
359 utility). @option{-ucspi} option should be used instead of @option{-inetd}.
362 @command{nncp-call} can be UCSPI-TCP client, using @option{-ucspi} option.
365 Do not exit if some of MCD network interfaces can not be listened --
366 only warn about that.
371 @section Release 7.4.0
375 Fixed simultaneous @command{nncp-daemon} and @command{nncp-caller} MCD work.
380 @section Release 7.3.2
384 @command{hjson-cli} utility builds in vendor-mode now.
389 @section Release 7.3.1

396 Severely decreased memory usage of MTH hashing.
401 @section Release 7.3.0
405 Fixed some workability problems on 32-bit systems with big files.
408 Ability to use directory with a bunch of files as a configuration.
409 @command{nncp-cfgdir} command appeared.
414 @section Release 7.2.1
418 Small optimizations in online commands.
423 @section Release 7.2.0
427 @command{nncp-trns} command appeared for manual transition packets creation.
430 If destination node of transitional packet has non empty @option{via}
431 route, then do not ignore, but use it.
434 Do not relay multicast packet to area message's originator, that
435 obviously has seen its own packet.
438 Much less memory usage during MTH hashing when offset is zero: when
439 packet is not resumed, but for example checked with @command{nncp-check}
445 @section Release 7.1.1
449 Fixed failing directories @code{fsync} after @file{.seen} file creation.
454 @section Release 7.1.0
458 Multicasting areas feature appeared. Implemented merely by an additional
459 plain packet type with @command{nncp-toss}, @command{nncp-file} and
460 @command{nncp-exec} commands modification.
463 Fixed workability of @command{nncp-file} and @command{nncp-exec}
464 commands, that use temporary file (@code{stdin} and @option{-use-tmp}).
467 Fixed disappearing bad return code in @command{nncp-exec} command.
470 Fixed invalid @file{.hdr} generation when transitional packets are used.
473 @option{-all} option appeared in @command{nncp-rm} command, applying to
474 all the nodes at once.
477 @option{-cycle} option appeared in @command{nncp-check} command, looping
478 the check in infinite cycle.
481 @command{nncp-rm} command can take node alias name.
484 @command{nncp-pkt} can parse @file{.hdr} files.
489 @section Release 7.0.0
493 Minimal required Go version is 1.13.
496 Merkle Tree-based Hashing with BLAKE3 (MTH) is used instead of BLAKE2b.
497 Because of that, there are backward @strong{incompatible} changes of
498 encrypted files (everything laying in the spool directory) and
499 @file{.meta} files of chunked transfer.
501 Current implementation is far from being optimal: it lacks
502 parallelizable calculations and has higher memory consumption: nearly
503 512 KiB for each 1 GiB of file's data. Future performance and memory
504 size optimizations should not lead to packet's format change. But it is
505 still several times faster than BLAKE2b.
508 Resumed online downloads, because of MTH, require reading only of the
509 preceding part of file, not the whole one as was before.
512 @command{nncp-hash} utility appeared for calculating file's MTH hash.
515 BLAKE2 KDF and XOF functions are replaced with BLAKE3 in encrypted
516 packets. Lowering number of used primitives. Also, its encrypted
517 packet's header is used as an associated data during encryption.
520 MultiCast Discovery uses
521 @verb{|ff02::4e4e:4350|} address instead of @verb{|ff02::1|}.
524 @command{nncp-cfgenc} mistakenly asked passphrase three times during encryption.
527 @command{nncp-stat} reports about partly downloaded packets.
530 Updated dependencies.
535 @section Release 6.6.0
539 @command{nncp-daemon}, @command{nncp-call} and @command{nncp-caller}
540 commands wait for all background checksummers completion after
541 connection is finished.
544 Added possibility of address determining through multicast announcement
545 in local area network, so called MCD (MultiCast Discovery).
550 @section Release 6.5.0
554 Fixed segfault in @command{nncp-daemon} when SP handshake did not succeed.
557 Fixed possible bad return code ignoring in automatic tosser.
560 Fixed race during file descriptors closing when online protocol call is
561 finished, that could lead to write error of received packet fragment.
564 Kill all packet transmission progress bars in @command{nncp-daemon},
565 @command{nncp-call} and @command{nncp-caller} when call is finished.
570 @section Release 6.4.0
574 Fixed possible race in online protocol, that lead to panic.
579 @section Release 6.3.0
583 Fixed possible panic while showing progress during online protocol.
588 @section Release 6.2.1
592 Three places in logs contained excess @code{%s}.
597 @section Release 6.2.0
601 Returned @command{nncp-caller}'s @option{-autotoss*} options workability.
604 Yet another logging refactoring and simplification.
605 Should be no visible differences to the end user.
610 @section Release 6.1.0
614 Optimization: most commands do not keep opened file descriptors now.
615 Previously you can exceed maximal number of opened files if you have got
616 many packets in the spool directory.
619 Optimization: do not close file descriptor of the file we download
620 online. Previously each chunk lead to expensive open/close calls.
623 Online downloaded files are saved with @file{.nock} (non-checksummed)
624 suffix, waiting either for @command{nncp-check}, or online daemons to
625 perform integrity check.
628 Optimization: files, that are not resumed, are checksummed immediately
629 during the online download, skipping @file{.nock}-intermediate step.
632 Ability to store encrypted packet's header in @file{.hdr} file, close to
633 the packet itself. That can greatly increase performance of packets
634 listing on filesystems with big block's size.
639 @section Release 6.0.0
643 Log uses human readable and easy machine parseable
644 @url{https://www.gnu.org/software/recutils/, recfile} format for the
645 records, instead of structured RFC 3339 lines. Old logs are not readable
646 by @command{nncp-log} anymore.
649 @option{-autotoss*} option workability with @command{nncp-daemon}'s
650 @option{-inetd} mode.
653 Call's @option{when-tx-exists} allows to make a call only when outbound
654 packets exists. Combined with seconds-aware cron expression that can be
655 used as some kind of auto dialler.
658 @command{nncp-cronexpr} command allows you to check validity and
659 expectations of specified cron expression.
664 @section Release 5.6.0
668 @option{-autotoss*} option runs tosser not after the call, but every
669 second while it is active.
672 @option{autotoss}, @option{autotoss-doseen},
673 @option{autotoss-nofile}, @option{autotoss-nofreq},
674 @option{autotoss-noexec}, @option{autotoss-notrns} options available in
675 @option{calls} configuration section. You can configure per-call
676 automatic tosser options.
679 Use vendoring, instead of @env{$GOPATH} overriding during tarball
680 installation, because current minimal Go's version is 1.12 and it

690 Respect for @env{$BINDIR}, @env{$INFODIR} and @env{$DOCDIR} environment
691 variables in @file{config} during installation.
696 @section Release 5.5.0
700 Bugfixes in @command{nncp-call(er)}/@command{nncp-daemon},
701 @command{nncp-bundle} and @command{nncp-stat}.
704 @command{nncp-rm} has @option{-dryrun} and @option{-older} options now.
707 @command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
708 options now. Uncompressed packets are not compatible with previous NNCP
712 @command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
713 have @option{-autotoss*} options for running tosser after call is ended.
716 Updated dependencies. Minimal required Go version is 1.12.
721 @section Release 5.4.1
725 Fixed @code{SENDMAIL} variable usage during the build.
730 @section Release 5.4.0
734 Updated dependencies.
737 Build system is moved from Makefiles to @url{http://cr.yp.to/redo.html, redo}.
738 This should not influence package maintainers, because minimal @command{redo}
739 implementation is included in tarball.
744 @section Release 5.3.3
748 More various error checks.
751 Updated dependencies.
756 @section Release 5.3.2
760 Fixed incorrect logic of @option{onlinedeadline} timeout, where
761 connection won't take into account incoming packets events and will
762 forcefully disconnect.
767 @section Release 5.3.1
771 Fixed @option{onlinedeadline} workability with call addresses that use
772 external commands (@verb{#"|somecmd"#}).
775 @command{nncp-stat} has @option{-pkt} option displaying information
776 about each packet in the spool.
781 @section Release 5.3.0
785 Progress messages contain prefix, describing the running action.
788 Fixed not occurring handshake messages padding.
791 Finish all SP protocol related goroutines, less memory leak.
794 SP protocol generates less socket write calls, thus generating less TCP
798 Check @option{onlinedeadline} and @option{maxonlinetime} options every
799 second, independently from socket reads (up to 10 seconds).
802 Once per minute, if no other traffic exists, PING packets are sent in
803 SP-connection. That allows faster determining of connection unworkability.
806 @command{nncp-toss} uses lock-file to prevent simultaneous tossing.
811 @section Release 5.2.1
815 Fixed SP protocol error handling, sometimes causing program panic.
820 @section Release 5.2.0
824 Most commands by default show oneline operations progress.
825 @option{-progress}, @option{-noprogress} command line options,
826 @option{noprogress} configuration file option appeared.
829 Fixed incorrect @command{nncp-check} command return code, that returned
830 bad code when everything is good.
833 Free disk space check during @command{nncp-bundle -rx} call.
838 @section Release 5.1.2
842 @strong{Critical} vulnerability: remote peers authentication could lead
843 to incorrect identification of remote side, allowing foreign encrypted

877 file options replaced with the structure:
878 @option{freq: @{path: @dots{}, minsize: @dots{}, chunked: @dots{}@}}.
881 Added @option{freq.maxsize} configuration file option, forbidding of
882 freq sending larger than specified size.
885 Ability to notify about successfully executed commands (exec) with
886 @option{notify.exec} configuration file option.
891 @section Release 5.0.0
895 @strong{Incompatible} configuration file format change: YAML is
896 replaced with Hjson, due to its simplicity, without noticeable lack
897 of either functionality or convenience.
900 @strong{Incompatible} plain packet format changes. Older versions are
901 not supported. @code{zlib} compression is replaced with
902 @code{Zstandard}, due to its speed and efficiency, despite library
903 version is not mature enough.
906 Ability to call remote nodes via pipe call of external command, not only
910 @command{nncp-cfgnew} generates configuration file with many
911 comments. @option{-nocomments} option can be used for an old

916 avoid possible collisions with @file{.nncp.chunkCTR}.
919 Ability to override process umask through configuration file option.
922 Files and directories are created with 666/777 permissions by default,
923 allowing control with @command{umask}.
926 Updated dependencies.
929 Full usage of go modules for dependencies management
930 (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
933 Forbid any later GNU GPL version autousage
934 (project's licence now is GNU GPLv3-only).
941 @item Workability on GNU/Linux systems and Go 1.10 is fixed.
949 @strong{Incompatible} encrypted and eblob packet format change: AEAD
950 encryption mode with 128 KiB blocks is used now, because previously
951 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
952 decrypted data to external command. Older versions are not supported.
955 Available free space checking before copying in @command{nncp-xfer},

993 Possibly it was transferred out-of-bound and remote side needs to be
997 If higher priority packet is spooled, then @command{nncp-daemon} will
998 queue its sending first, interrupting lower priority transmissions.
1001 Simple packet rate limiter added to online-related tools
1002 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
1005 Ability to specify niceness with symbolic notation:
1006 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
1009 Changed default niceness levels:
1010 for @command{nncp-exec} from 64 to 96,
1011 for @command{nncp-freq} from 64 to 160,
1012 for @command{nncp-file} from 196 to 224.

1021 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
1022 valid tar archives, but Go 1.9 made them invalid because of long paths
1023 inside. NNCP accidentally was dependant on that bug. Explicit adding of

1044 Ability to queue remote command execution, by configuring @option{exec}
1045 option in configuration file and using @command{nncp-exec} command:
1048 @command{nncp-mail} command is replaced with more flexible
1049 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
1050 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
1052 @option{sendmail} configuration file option is replaced with
1053 @option{exec}. @code{sendmail: [@dots{}]} must be replaced with
1054 @code{exec: sendmail: [@dots{}]}.
1058 Ability to override @option{via} configuration option for destination
1059 node via @option{-via} command line option for following commands:
1060 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
1063 Chunked files, having size less than specified chunk size, will be sent
1064 as an ordinary single file.
1067 Exec commands are invoked with additional @env{$NNCP_NICE} and
1068 @env{$NNCP_SELF} environment variables.
1071 Files, that are sent as a reply to freq, have niceness level taken from
1072 the freq packet. You can set desired niceness during @command{nncp-freq}
1073 invocation using @option{-replynice} option.
1076 @command{nncp-toss} command can ignore specified packet types during
1077 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
