85 @command{nncp-ack} does not acknowledge ACK-packets, preventing an
89 @command{nncp-ack} previously did not remove corresponding @file{hdr/} files.
92 @command{nncp-rm} now takes list of packet from @code{stdin} when
93 @option{-pkt} option is used.
96 @command{nncp-ack} now generates list of ACK packets it created, that
97 could be used as an input to @command{nncp-rm} to remove outbound ACK
103 @section Release 8.6.0
107 @command{nncp-xfer} checks if locally copied packet's checksum differs
108 from the source's one.
111 @command{nncp-call} has bad return code if its queues contain unfinished jobs.
114 @command{nncp-ack} command appeared, that sends explicit packet receipt
115 acknowledgement (ACK packet). That acknowledgement deletes referenced
116 packet from the outbound spool.
119 Ability to turn @code{fsync} operation off using @env{$NNCPNOSYNC=1}
120 environment variable.
123 Added various indices in documentation, that should help searching in it.
128 @section Release 8.5.0
132 Fixed @command{nncp-bundle} workability.
135 Mistakenly @option{-mcd-wait} option was enabled by default in
139 Ability to override internal default timeout for online protocol through
140 @env{$NNCPDEADLINE} environment variable. Can be useful for very high
144 NNCP builds on OpenBSD.
149 @section Release 8.4.0
153 Multicast related interface names (@code{mcd-listen} and @code{mcd-send}
154 configuration options) are now regular expressions. By default
155 @command{nncp-cfgnew} uncomments them now with @code{.*} interface name.
158 @command{nncp-call} command has @option{-mcd-wait} option to wait for
159 multicast packet about node's address.
162 @command{nncp-file} command skips everything that is neither regular
163 file nor directory during pax-archive creation.
168 @section Release 8.3.0
172 Fixed building issues on 32-bit systems.
177 @section Release 8.2.0
181 Yggdrasil uses pure-Go IPv6+TCP network stack, instead of naked μTP
182 transport protocol, making it able to work as an ordinary TCP server
183 inside overlay network.
186 Yggdrasil's @code{prv;bind1,bind2;pub@dots{}}-like configuration strings are
187 replaced with URL-like ones (@code{yggdrasils://PRV?bind=BIND1&bind=BIND2&pub=PUB}).
190 Ability to pass multicast-related parameters to Yggdrasil configuration.
193 @command{nncp-daemon} is able to listen on both TCP and Yggdrasil-driven
194 sockets simultaneously.
197 @command{nncp-daemon}'s listening on peering endpoint socket is optional
198 -- you can be reached through the peers.
203 @section Release 8.1.0
207 @command{nncp-cfgdir} does not require @code{self} section existence in
211 Ability to act as Yggdrasil network client, using online protocol on top of it.
216 @section Release 8.0.2
220 Fixed sending ability to areas.
225 @section Release 8.0.1
229 Fixed incorrect @code{freq.chunked} value calculation. If it was missed,
230 then chunked transfer mode was forcefully turned on anyway.
233 Fixed incorrect full file's size calculation in @file{.nncp.meta}.
238 @section Release 8.0.0
242 @strong{Incompatible} encrypted packet format change: payload and pad
243 sizes are sent in-bound in the encrypted stream. That gives ability to
244 streamingly create encrypted packets, without knowing sizes in advance,
245 without creating temporary file or buffer data in memory.
248 Proper encrypted packet padding verification is done now. This is not
249 critical issue, but previously neither padding value, nor its size were
250 authenticated, giving ability to iteratively strip trailing bytes and
251 determine payload's size by observing the reaction of the encrypted
255 @command{nncp-exec} loses its @option{-use-tmp} option, because of
256 streaming-compatible encrypted packets format.
259 @command{nncp-file} and @command{nncp-exec} commands have
260 @option{-maxsize} option, limiting maximal resulting encrypted packet's
261 maximal size (returning error if it is exceeded). Could be useful,
262 because no payload size could be known in advance.
267 @section Release 7.7.0
271 Experimental @code{kqueue} and @code{inotify} based notifications
272 support about spool directory changes, for reducing their often reading
276 @file{.seen} and @file{.hdr} files moved to @file{seen/} and @file{hdr/}
277 subdirectories, for faster scanning of spool directories.
278 Current files migration required:
281 $ find $NNCPSPOOL -type f -name "*.hdr" -exec rm @{@} +
283 $ find $NNCPSPOOL -type d -name rx | while read rx ; do
286 find . -type f -name "*.seen" | while read fn ; do
287 mv $fn seen/$@{fn%.seen@}
291 $ find $NNCPSPOOL -type d -name area | while read area ; do
292 find $area -type f -name "*.seen" | while read fn ; do
301 @section Release 7.6.0
305 Logging may be done to specified opened file descriptor
306 (@env{$NNCPLOG=FD:5} for example).
307 That is friendly to use under @command{daemontools}.
310 Added additional checks of public keys existence in configuration file,
311 preventing some commands from failing.
316 @section Release 7.5.1
320 NNCP builds on NetBSD.
325 @section Release 7.5.0
329 @command{nncp-daemon} is compatible with UCSPI-TCP interface, so log
330 will contain remote side's address (when running under appropriate
331 utility). @option{-ucspi} option should be used instead of @option{-inetd}.
334 @command{nncp-call} can be UCSPI-TCP client, using @option{-ucspi} option.
337 Do not exit if some of MCD network interfaces can not be listened --
338 only warn about that.
343 @section Release 7.4.0
347 Fixed simultaneous @command{nncp-daemon} and @command{nncp-caller} MCD work.
352 @section Release 7.3.2
356 @command{hjson-cli} utility builds in vendor-mode now.
361 @section Release 7.3.1
365 Fixed possibly left opened file descriptor in online commands.
368 Severely decreased memory usage of MTH hashing.
373 @section Release 7.3.0
377 Fixed some workability problems on 32-bit systems with big files.
380 Ability to use directory with a bunch of files as a configuration.
381 @command{nncp-cfgdir} command appeared.
386 @section Release 7.2.1
390 Small optimizations in online commands.
395 @section Release 7.2.0
399 @command{nncp-trns} command appeared for manual transition packets creation.
402 If destination node of transitional packet has non empty @option{via}
403 route, then do not ignore, but use it.
406 Do not relay multicast packet to area message's originator, that
407 obviously has seen its own packet.
410 Much less memory usage during MTH hashing when offset is zero: when
411 packet is not resumed, but for example checked with @command{nncp-check}
417 @section Release 7.1.1
421 Fixed failing directories @code{fsync} after @file{.seen} file creation.
426 @section Release 7.1.0
430 Multicasting areas feature appeared. Implemented merely by an additional
431 plain packet type with @command{nncp-toss}, @command{nncp-file} and
432 @command{nncp-exec} commands modification.
435 Fixed workability of @command{nncp-file} and @command{nncp-exec}
436 commands, that use temporary file (@code{stdin} and @option{-use-tmp}).
439 Fixed disappearing bad return code in @command{nncp-exec} command.
442 Fixed invalid @file{.hdr} generation when transitional packets are used.
445 @option{-all} option appeared in @command{nncp-rm} command, applying to
446 all the nodes at once.
449 @option{-cycle} option appeared in @command{nncp-check} command, looping
450 the check in infinite cycle.
453 @command{nncp-rm} command can take node alias name.
456 @command{nncp-pkt} can parse @file{.hdr} files.
461 @section Release 7.0.0
465 Minimal required Go version is 1.13.
468 Merkle Tree-based Hashing with BLAKE3 (MTH) is used instead of BLAKE2b.
469 Because of that, there are backward @strong{incompatible} changes of
470 encrypted files (everything laying in the spool directory) and
471 @file{.meta} files of chunked transfer.
473 Current implementation is far from being optimal: it lacks
474 parallelizable calculations and has higher memory consumption: nearly
475 512 KiB for each 1 GiB of file's data. Future performance and memory
476 size optimizations should not lead to packet's format change. But it is
477 still several times faster than BLAKE2b.
480 Resumed online downloads, because of MTH, require reading only of the
481 preceding part of file, not the whole one as was before.
484 @command{nncp-hash} utility appeared for calculating file's MTH hash.
487 BLAKE2 KDF and XOF functions are replaced with BLAKE3 in encrypted
488 packets. Lowering number of used primitives. Also, its encrypted
489 packet's header is used as an associated data during encryption.
492 MultiCast Discovery uses
493 @verb{|ff02::4e4e:4350|} address instead of @verb{|ff02::1|}.
496 @command{nncp-cfgenc} mistakenly asked passphrase three times during encryption.
499 @command{nncp-stat} reports about partly downloaded packets.
502 Updated dependencies.
507 @section Release 6.6.0
511 @command{nncp-daemon}, @command{nncp-call} and @command{nncp-caller}
512 commands wait for all background checksummers completion after
513 connection is finished.
516 Added possibility of address determining through multicast announcement
517 in local area network, so called MCD (MultiCast Discovery).
522 @section Release 6.5.0
526 Fixed segfault in @command{nncp-daemon} when SP handshake did not succeed.
529 Fixed possible bad return code ignoring in automatic tosser.
532 Fixed race during file descriptors closing when online protocol call is
533 finished, that could lead to write error of received packet fragment.
536 Kill all packet transmission progress bars in @command{nncp-daemon},
537 @command{nncp-call} and @command{nncp-caller} when call is finished.
542 @section Release 6.4.0
546 Fixed possible race in online protocol, that lead to panic.
551 @section Release 6.3.0
555 Fixed possible panic while showing progress during online protocol.
560 @section Release 6.2.1
564 Three places in logs contained excess @code{%s}.
569 @section Release 6.2.0
573 Returned @command{nncp-caller}'s @option{-autotoss*} options workability.
576 Yet another logging refactoring and simplification.
577 Should be no visible differences to the end user.
582 @section Release 6.1.0
586 Optimization: most commands do not keep opened file descriptors now.
587 Previously you can exceed maximal number of opened files if you have got
588 many packets in the spool directory.
591 Optimization: do not close file descriptor of the file we download
592 online. Previously each chunk lead to expensive open/close calls.
595 Online downloaded files are saved with @file{.nock} (non-checksummed)
596 suffix, waiting either for @command{nncp-check}, or online daemons to
597 perform integrity check.
600 Optimization: files, that are not resumed, are checksummed immediately
601 during the online download, skipping @file{.nock}-intermediate step.
604 Ability to store encrypted packet's header in @file{.hdr} file, close to
605 the packet itself. That can greatly increase performance of packets
606 listing on filesystems with big block's size.
611 @section Release 6.0.0
615 Log uses human readable and easy machine parseable
616 @url{https://www.gnu.org/software/recutils/, recfile} format for the
617 records, instead of structured RFC 3339 lines. Old logs are not readable
618 by @command{nncp-log} anymore.
621 @option{-autotoss*} option workability with @command{nncp-daemon}'s
622 @option{-inetd} mode.
625 Call's @option{when-tx-exists} allows to make a call only when outbound
626 packets exists. Combined with seconds-aware cron expression that can be
627 used as some kind of auto dialler.
630 @command{nncp-cronexpr} command allows you to check validity and
631 expectations of specified cron expression.
636 @section Release 5.6.0
640 @option{-autotoss*} option runs tosser not after the call, but every
641 second while it is active.
644 @option{autotoss}, @option{autotoss-doseen},
645 @option{autotoss-nofile}, @option{autotoss-nofreq},
646 @option{autotoss-noexec}, @option{autotoss-notrns} options available in
647 @option{calls} configuration section. You can configure per-call
648 automatic tosser options.
651 Use vendoring, instead of @env{$GOPATH} overriding during tarball
652 installation, because current minimal Go's version is 1.12 and it
658 @section Release 5.5.1
662 Respect for @env{$BINDIR}, @env{$INFODIR} and @env{$DOCDIR} environment
663 variables in @file{config} during installation.
668 @section Release 5.5.0
672 Bugfixes in @command{nncp-call(er)}/@command{nncp-daemon},
673 @command{nncp-bundle} and @command{nncp-stat}.
676 @command{nncp-rm} has @option{-dryrun} and @option{-older} options now.
679 @command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
680 options now. Uncompressed packets are not compatible with previous NNCP
684 @command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
685 have @option{-autotoss*} options for running tosser after call is ended.
688 Updated dependencies. Minimal required Go version is 1.12.
693 @section Release 5.4.1
697 Fixed @code{SENDMAIL} variable usage during the build.
702 @section Release 5.4.0
706 Updated dependencies.
709 Build system is moved from Makefiles to @url{http://cr.yp.to/redo.html, redo}.
710 This should not influence package maintainers, because minimal @command{redo}
711 implementation is included in tarball.
716 @section Release 5.3.3
720 More various error checks.
723 Updated dependencies.
728 @section Release 5.3.2
732 Fixed incorrect logic of @option{onlinedeadline} timeout, where
733 connection won't take into account incoming packets events and will
734 forcefully disconnect.
739 @section Release 5.3.1
743 Fixed @option{onlinedeadline} workability with call addresses that use
744 external commands (@verb{#"|somecmd"#}).
747 @command{nncp-stat} has @option{-pkt} option displaying information
748 about each packet in the spool.
753 @section Release 5.3.0
757 Progress messages contain prefix, describing the running action.
760 Fixed not occurring handshake messages padding.
763 Finish all SP protocol related goroutines, less memory leak.
766 SP protocol generates less socket write calls, thus generating less TCP
770 Check @option{onlinedeadline} and @option{maxonlinetime} options every
771 second, independently from socket reads (up to 10 seconds).
774 Once per minute, if no other traffic exists, PING packets are sent in
775 SP-connection. That allows faster determining of connection unworkability.
778 @command{nncp-toss} uses lock-file to prevent simultaneous tossing.
783 @section Release 5.2.1
787 Fixed SP protocol error handling, sometimes causing program panic.
792 @section Release 5.2.0
796 Most commands by default show oneline operations progress.
797 @option{-progress}, @option{-noprogress} command line options,
798 @option{noprogress} configuration file option appeared.
801 Fixed incorrect @command{nncp-check} command return code, that returned
802 bad code when everything is good.
805 Free disk space check during @command{nncp-bundle -rx} call.
810 @section Release 5.1.2
814 @strong{Critical} vulnerability: remote peers authentication could lead
815 to incorrect identification of remote side, allowing foreign encrypted
819 Bugfix: private and public Noise keys were swapped in newly created
820 configuration files, that lead to inability to authenticate online peers.
823 Explicit directories @code{fsync}-ing for guaranteed files renaming.
828 @section Release 5.1.1
832 Fixed workability of @command{nncp-file} with @option{-chunked 0} option.

841 @command{nncp-file} can send directories, automatically creating pax
845 Free disk space is checked during outbound packets creation.
848 @option{freq}, @option{freqminsize}, @option{freqchunked} configuration
849 file options replaced with the structure:
850 @option{freq: @{path: @dots{}, minsize: @dots{}, chunked: @dots{}@}}.
853 Added @option{freq.maxsize} configuration file option, forbidding of
854 freq sending larger than specified size.
857 Ability to notify about successfully executed commands (exec) with
858 @option{notify.exec} configuration file option.
863 @section Release 5.0.0
867 @strong{Incompatible} configuration file format change: YAML is
868 replaced with Hjson, due to its simplicity, without noticeable lack
869 of either functionality or convenience.
872 @strong{Incompatible} plain packet format changes. Older versions are
873 not supported. @code{zlib} compression is replaced with
874 @code{Zstandard}, due to its speed and efficiency, despite library
875 version is not mature enough.
878 Ability to call remote nodes via pipe call of external command, not only
882 @command{nncp-cfgnew} generates configuration file with many
883 comments. @option{-nocomments} option can be used for an old
887 Duplicate filenames have @file{.CTR} suffix, instead of @file{CTR}, to
888 avoid possible collisions with @file{.nncp.chunkCTR}.
891 Ability to override process umask through configuration file option.
894 Files and directories are created with 666/777 permissions by default,
895 allowing control with @command{umask}.
898 Updated dependencies.
901 Full usage of go modules for dependencies management
902 (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
905 Forbid any later GNU GPL version autousage
906 (project's licence now is GNU GPLv3-only).
913 @item Workability on GNU/Linux systems and Go 1.10 is fixed.
921 @strong{Incompatible} encrypted and eblob packet format change: AEAD
922 encryption mode with 128 KiB blocks is used now, because previously
923 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
924 decrypted data to external command. Older versions are not supported.
927 Available free space checking before copying in @command{nncp-xfer},
928 @command{nncp-daemon}, @command{nncp-call(er)}.
931 @command{nncp-call} has ability only to list packets on remote node,
932 without their transmission.
935 @command{nncp-call} has ability to transfer only specified packets.
938 Workability of @option{xxrate} preference in @option{calls}
939 configuration file section.
942 Dependant libraries are updated.
948 Begin using of @code{go.mod} subsystem.
955 @item @command{nncp-daemon} can be run as @command{inetd}-service.
963 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
964 if @file{.seen} exists and treat it like file was already downloaded.
965 Possibly it was transferred out-of-bound and remote side needs to be
969 If higher priority packet is spooled, then @command{nncp-daemon} will
970 queue its sending first, interrupting lower priority transmissions.
973 Simple packet rate limiter added to online-related tools
974 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
977 Ability to specify niceness with symbolic notation:
978 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
981 Changed default niceness levels:
982 for @command{nncp-exec} from 64 to 96,
983 for @command{nncp-freq} from 64 to 160,
984 for @command{nncp-file} from 196 to 224.
992 @strong{Incompatible} @emph{bundle} archive format changes and
993 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
994 valid tar archives, but Go 1.9 made them invalid because of long paths
995 inside. NNCP accidentally was dependant on that bug. Explicit adding of
996 @file{NNCP/} directory in archive restores workability with valid tar
1001 @section Release 3.1
1004 Ability to disable relaying at all using @verb{|-via -|} command line option.
1008 @section Release 3.0
1012 @strong{Incompatible} plain packet format changes. Older versions are
1016 Ability to queue remote command execution, by configuring @option{exec}
1017 option in configuration file and using @command{nncp-exec} command:
1020 @command{nncp-mail} command is replaced with more flexible
1021 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
1022 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
1024 @option{sendmail} configuration file option is replaced with
1025 @option{exec}. @code{sendmail: [@dots{}]} must be replaced with
1026 @code{exec: sendmail: [@dots{}]}.
1030 Ability to override @option{via} configuration option for destination
1031 node via @option{-via} command line option for following commands:
1032 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
1035 Chunked files, having size less than specified chunk size, will be sent
1036 as an ordinary single file.
1039 Exec commands are invoked with additional @env{$NNCP_NICE} and
1040 @env{$NNCP_SELF} environment variables.
1043 Files, that are sent as a reply to freq, have niceness level taken from
1044 the freq packet. You can set desired niceness during @command{nncp-freq}
1045 invocation using @option{-replynice} option.
1048 @command{nncp-toss} command can ignore specified packet types during
1049 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
1053 @command{nncp-file} command uses
1054 @option{FreqMinSize}/@option{FreqChunked} configuration file options
1055 for @option{-minsize}/@option{-chunked} by default. You can turn this
1056 off by specifying zero value.

1065 @strong{Incompatible} encrypted/eblob packet format changes. Older
1066 versions are not supported.
1069 Twofish encryption algorithm is replaced with ChaCha20. It is much more
1070 faster. One cryptographic primitive less.
1073 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
1074 another cryptographic primitive less (assuming that BLAKE2X is nearly
1075 identical to BLAKE2).

1084 @strong{Incompatible} encrypted packet format changes. Older versions
1088 @command{nncp-bundle} command can either create stream of encrypted
1089 packets, or digest it. It is useful when dealing with
1090 @code{stdin}/@code{stdout} based transmission methods (like writing to
1091 CD-ROM without intermediate prepared ISO image and working with tape
1095 @command{nncp-toss} is able to create @file{.seen} files preventing
1096 duplicate packets receiving.
1099 Single background checksum verifier worker is allowed in
1100 @command{nncp-call}. This is helpful when thousands of small inbound
1101 packets could create many goroutines.
1104 Ability to override path to spool directory and logfile through either
1105 command line argument, or environment variable.
1108 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
1109 @file{.part}, @file{.lock} and temporary files.

1145 Little bugfix in @command{nncp-file} command, where @option{-minsize}
1146 option for unchunked transfer was not in KiBs, but in bytes.
1150 @section Release 0.7
1154 Ability to feed @command{nncp-file} from @code{stdin}, that uses an
1155 encrypted temporary file for that.
1158 Chunked files transmission appeared with corresponding
1159 @command{nncp-reass} command and @option{freqchunked} configuration file
