16 @option{autotoss-nofile}, @option{autotoss-nofreq},
17 @option{autotoss-noexec}, @option{autotoss-notrns} options available in
18 @option{calls} configuration section. You can configure per-call
19 automatic tosser options.
22 Use vendoring, instead of @env{GOPATH} overriding during tarball
23 installation, because current minimal Go's version is 1.12 and it
29 @section Release 5.5.1
33 Respect for @env{BINDIR}, @env{INFODIR} and @env{DOCDIR} environment
34 variables in @file{config} during installation.
39 @section Release 5.5.0
43 Bugfixes in @command{nncp-call(er)}/@command{nncp-daemon},
44 @command{nncp-bundle} and @command{nncp-stat}.
47 @command{nncp-rm} has @option{-dryrun} and @option{-older} options now.
50 @command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
51 options now. Uncompressed packets are not compatible with previous NNCP
55 @command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
56 have @option{-autotoss*} options for running tosser after call is ended.
59 Updated dependencies. Minimal required Go version is 1.12.
64 @section Release 5.4.1
68 Fixed @code{SENDMAIL} variable usage during the build.
73 @section Release 5.4.0
80 Build system is moved from Makefiles to @url{http://cr.yp.to/redo.html, redo}.
81 This should not influence package maintainers, because minimal @command{redo}
82 implementation is included in tarball.
87 @section Release 5.3.3
91 More various error checks.
99 @section Release 5.3.2
103 Fixed incorrect logic of @option{onlinedeadline} timeout, where
104 connection won't take into account incoming packets events and will
105 forcefully disconnect.
110 @section Release 5.3.1
114 Fixed @option{onlinedeadline} workability with call addresses that use
115 external commands (@verb{#"|somecmd"#}).
118 @command{nncp-stat} has @option{-pkt} option displaying information
119 about each packet in the spool.
124 @section Release 5.3.0
128 Progress messages contain prefix, describing the running action.
131 Fixed not occurring handshake messages padding.
134 Finish all SP protocol related goroutines, less memory leak.
137 SP protocol generates less socket write calls, thus generating less TCP
141 Check @option{onlinedeadline} and @option{maxonlinetime} options every
142 second, independently from socket reads (up to 10 seconds).
145 Once per minute, if no other traffic exists, PING packets are sent in
146 SP-connection. That allows faster determining of connection unworkability.
149 @command{nncp-toss} uses lock-file to prevent simultaneous tossing.
154 @section Release 5.2.1
158 Fixed SP protocol error handling, sometimes causing program panic.

181 @section Release 5.1.2
185 @strong{Critical} vulnerability: remote peers authentication could lead
186 to incorrect identification of remote side, allowing foreign encrypted
190 Bugfix: private and public Noise keys were swapped in newly created

216 Free disk space is checked during outbound packets creation.
219 @option{freq}, @option{freqminsize}, @option{freqchunked} configuration
220 file options replaced with the structure:
221 @option{freq: @{path: ..., minsize: ..., chunked: ...@}}.
224 Added @option{freq.maxsize} configuration file option, forbidding of
225 freq sending larger than specified size.
228 Ability to notify about successfully executed commands (exec) with
229 @option{notify.exec} configuration file option.
234 @section Release 5.0.0
238 @strong{Incompatible} configuration file format change: YAML is
239 replaced with Hjson, due to its simplicity, without noticeable lack
240 of either functionality or convenience.
243 @strong{Incompatible} plain packet format changes. Older versions are
244 not supported. @code{zlib} compression is replaced with
245 @code{Zstandard}, due to its speed and efficiency, despite library
246 version is not mature enough.
249 Ability to call remote nodes via pipe call of external command, not only
253 @command{nncp-cfgnew} generates configuration file with many
254 comments. @option{-nocomments} option can be used for an old
258 Duplicate filenames have @file{.CTR} suffix, instead of @file{CTR}, to
259 avoid possible collisions with @file{.nncp.chunkCTR}.
262 Ability to override process umask through configuration file option.
265 Files and directories are created with 666/777 permissions by default,
266 allowing control with @command{umask}.
269 Updated dependencies.
272 Full usage of go modules for dependencies management
273 (@code{go.cypherpunks.ru/nncp/v5} namespace is used).
276 Forbid any later GNU GPL version autousage
277 (project's licence now is GNU GPLv3-only).
284 @item Workability on GNU/Linux systems and Go 1.10 is fixed.
292 @strong{Incompatible} encrypted and eblob packet format change: AEAD
293 encryption mode with 128 KiB blocks is used now, because previously
294 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
295 decrypted data to external command. Older versions are not supported.
298 Available free space checking before copying in @command{nncp-xfer},
299 @command{nncp-daemon}, @command{nncp-call(er)}.
302 @command{nncp-call} has ability only to list packets on remote node,
303 without their transmission.
306 @command{nncp-call} has ability to transfer only specified packets.
309 Workability of @option{xxrate} preference in @option{calls}
310 configuration file section.
313 Dependant libraries are updated.
319 Begin using of @code{go.mod} subsystem.
326 @item @command{nncp-daemon} can be run as @command{inetd}-service.
334 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
335 if @file{.seen} exists and treat it like file was already downloaded.
336 Possibly it was transferred out-of-bound and remote side needs to be
340 If higher priority packet is spooled, then @command{nncp-daemon} will
341 queue its sending first, interrupting lower priority transmissions.
344 Simple packet rate limiter added to online-related tools
345 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
348 Ability to specify niceness with symbolic notation:
349 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
352 Changed default niceness levels:
353 for @command{nncp-exec} from 64 to 96,
354 for @command{nncp-freq} from 64 to 160,
355 for @command{nncp-file} from 196 to 224.
363 @strong{Incompatible} @emph{bundle} archive format changes and
364 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
365 valid tar archives, but Go 1.9 made them invalid because of long paths
366 inside. NNCP accidentally was dependant on that bug. Explicit adding of
367 @file{NNCP/} directory in archive restores workability with valid tar
375 Ability to disable relaying at all using @verb{|-via -|} command line option.
383 @strong{Incompatible} plain packet format changes. Older versions are
387 Ability to queue remote command execution, by configuring @option{exec}
388 option in configuration file and using @command{nncp-exec} command:
391 @command{nncp-mail} command is replaced with more flexible
392 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
393 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
395 @option{sendmail} configuration file option is replaced with
396 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
397 @verb{|exec: sendmail: [...]|}.
401 Ability to override @option{via} configuration option for destination
402 node via @option{-via} command line option for following commands:
403 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
406 Chunked files, having size less than specified chunk size, will be sent
407 as an ordinary single file.
410 Exec commands are invoked with additional @env{NNCP_NICE} and
411 @env{NNCP_SELF} environment variables.
414 Files, that are sent as a reply to freq, have niceness level taken from
415 the freq packet. You can set desired niceness during @command{nncp-freq}
416 invocation using @option{-replynice} option.
419 @command{nncp-toss} command can ignore specified packet types during
420 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
424 @command{nncp-file} command uses
425 @option{FreqMinSize}/@option{FreqChunked} configuration file options
426 for @option{-minsize}/@option{-chunked} by default. You can turn this
427 off by specifying zero value.
436 @strong{Incompatible} encrypted/eblob packet format changes. Older
437 versions are not supported.
440 Twofish encryption algorithm is replaced with ChaCha20. It is much more
441 faster. One cryptographic primitive less.
444 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
445 another cryptographic primitive less (assuming that BLAKE2X is nearly
446 identical to BLAKE2).
455 @strong{Incompatible} encrypted packet format changes. Older versions
459 @command{nncp-bundle} command can either create stream of encrypted
460 packets, or digest it. It is useful when dealing with
461 @code{stdin}/@code{stdout} based transmission methods (like writing to
462 CD-ROM without intermediate prepared ISO image and working with tape
466 @command{nncp-toss} is able to create @file{.seen} files preventing
467 duplicate packets receiving.
470 Single background checksum verifier worker is allowed in
471 @command{nncp-call}. This is helpful when thousands of small inbound
472 packets could create many goroutines.
475 Ability to override path to spool directory and logfile through either
476 command line argument, or environment variable.
479 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
480 @file{.part}, @file{.lock} and temporary files.
485 @section Release 0.12
487 @item Sendmail command is called with @env{NNCP_SENDER} environment variable.
491 @section Release 0.11
493 @item @command{nncp-stat}'s command output is sorted by node name.
497 @section Release 0.10
500 @command{nncp-freq}'s @file{DST} argument is optional now. Last
501 @file{SRC} path's element will be used by default.
508 Fix @option{-rx}/@option{-tx} arguments processing in
509 @command{nncp-call} command. They were ignored.
516 Little bugfix in @command{nncp-file} command, where @option{-minsize}
517 option for unchunked transfer was not in KiBs, but in bytes.
525 Ability to feed @command{nncp-file} from @code{stdin}, that uses an
526 encrypted temporary file for that.
529 Chunked files transmission appeared with corresponding
530 @command{nncp-reass} command and @option{freqchunked} configuration file
531 entry. Useful for transferring big files over small storage devices.
534 @option{freqminsize} configuration file option, analogue to
535 @option{-minsize} one.
538 @command{nncp-xfer}'s @option{-force} option is renamed to
539 @option{-mkdir} for clarity.
542 @option{-minsize} option is specified in KiBs, not bytes, for
546 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
547 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
548 common prefix and are grouped together for convenience.
551 @command{nncp-cfgenc} command appeared, allowing configuration file
552 encryption/decryption, for keeping it safe without any either OpenPGP or
556 Cryptographic libraries (dependencies) are updated.
563 @item Small @command{nncp-rm} command appeared.
564 @item Cryptographic libraries (dependencies) are updated.
571 Trivial small fix in default niceness level of @command{nncp-file}
572 and @command{nncp-freq} commands.
580 Small fix in @command{nncp-call}, @command{nncp-caller},
581 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
585 @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is shorter
586 and more convenient to use.
589 @command{nncp-mincfg} command appeared: helper allowing to create
590 minimalistic stripped down configuration file without private keys, that
591 is useful during @command{nncp-xfer} usage.
598 @item Fixed compatibility with Go 1.6.
606 @strong{Incompatible} packet's format change (magic number is changed
607 too): size field is encrypted and is not send in plaintext anymore.
610 @option{-minsize} option gives ability to automatically pad outgoing
611 packets to specified minimal size.
614 @command{nncp-daemon} and @command{nncp-call}/@command{nncp-caller}
615 always check new @emph{tx} packets appearance in the background while
616 connected. Remote side is immediately notified.
619 @option{-onlinedeadline} option gives ability to configure timeout of
620 inactivity of online connection, when it could be disconnected. It could
621 be used to keep connection alive for a long time.
624 @option{-maxonlinetime} option gives ability to set maximal allowable
625 online connection aliveness time.
628 @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
631 @command{nncp-pkt} command can decompress the data.
