10 Workability on GNU/Linux systems and Go 1.10 is fixed.
17 @strong{Incompatible} encrypted and eblob packet format change: AEAD
18 encryption mode with 128 KiB blocks is used now, because previously
19 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
20 decrypted data to external command. Older versions are not supported.
22 Available free space checking before copying in @command{nncp-xfer},
23 @command{nncp-daemon}, @command{nncp-call(er)}.
25 @command{nncp-call} has ability only to list packets on remote node,
26 without their transmission.
28 @command{nncp-call} has ability to transfer only specified packets.
30 Workability of @option{xxrate} preference in @option{calls}
31 configuration file section.
33 Dependant libraries are updated.
37 Begin using of @code{go.mod} subsystem.
44 @command{nncp-daemon} can be run as @command{inetd}-service.
51 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
52 if @file{.seen} exists and treat it like file was already downloaded.
53 Possibly it was transferred out-of-bound and remote side needs to be
56 If higher priority packet is spooled, then @command{nncp-daemon} will
57 queue its sending first, interrupting lower priority transmissions.
59 Simple packet rate limiter added to online-related tools
60 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
62 Ability to specify niceness with symbolic notation:
63 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
65 Changed default niceness levels:
66 for @command{nncp-exec} from 64 to 96,
67 for @command{nncp-freq} from 64 to 160,
68 for @command{nncp-file} from 196 to 224.
75 @strong{Incompatible} @emph{bundle} archive format changes and
76 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
77 valid tar archives, but Go 1.9 made them invalid because of long paths
78 inside. NNCP accidentally was dependant on that bug. Explicit adding of
79 @file{NNCP/} directory in archive restores workability with valid tar
87 Ability to disable relaying at all using @verb{|-via -|} command line option.
94 @strong{Incompatible} plain packet format changes. Older versions are
97 Ability to queue remote command execution, by configuring @option{exec}
98 option in configuration file and using @command{nncp-exec} command:
101 @command{nncp-mail} command is replaced with more flexible
102 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
103 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
105 @option{sendmail} configuration file option is replaced with
106 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
107 @verb{|exec: sendmail: [...]|}.
110 Ability to override @option{via} configuration option for destination
111 node via @option{-via} command line option for following commands:
112 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
114 Chunked files, having size less than specified chunk size, will be sent
115 as an ordinary single file.
117 Exec commands are invoked with additional @env{NNCP_NICE} and
118 @env{NNCP_SELF} environment variables.
120 Files, that are sent as a reply to freq, have niceness level taken from
121 the freq packet. You can set desired niceness during @command{nncp-freq}
122 invocation using @option{-replynice} option.
124 @command{nncp-toss} command can ignore specified packet types during
125 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
128 @command{nncp-file} command uses
129 @option{FreqMinSize}/@option{FreqChunked} configuration file options
130 for @option{-minsize}/@option{-chunked} by default. You can turn this
131 off by specifying zero value.
138 @strong{Incompatible} encrypted/eblob packet format changes. Older
139 versions are not supported.
141 Twofish encryption algorithm is replaced with ChaCha20. It is much more
142 faster. One cryptographic primitive less.
144 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
145 another cryptographic primitive less (assuming that BLAKE2X is nearly
146 identical to BLAKE2).
153 @strong{Incompatible} encrypted packet format changes. Older versions
156 @command{nncp-bundle} command can either create stream of encrypted
157 packets, or digest it. It is useful when dealing with stdin/stdout based
158 transmission methods (like writing to CD-ROM without intermediate
159 prepared ISO image and working with tape drives).
161 @command{nncp-toss} is able to create @file{.seen} files preventing
162 duplicate packets receiving.
164 Single background checksum verifier worker is allowed in
165 @command{nncp-call}. This is helpful when thousands of small inbound
166 packets could create many goroutines.
168 Ability to override path to spool directory and logfile through either
169 command line argument, or environment variable.
171 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
172 @file{.part}, @file{.lock} and temporary files.
176 @section Release 0.12
179 Sendmail command is called with @env{NNCP_SENDER} environment variable.
183 @section Release 0.11
186 @command{nncp-stat}'s command output is sorted by node name.
190 @section Release 0.10
193 @command{nncp-freq}'s @file{DST} argument is optional now. Last
194 @file{SRC} path's element will be used by default.
201 Fix @option{-rx}/@option{-tx} arguments processing in
202 @command{nncp-call} command. They were ignored.
209 Little bugfix in @command{nncp-file} command, where @option{-minsize}
210 option for unchunked transfer was not in KiBs, but in bytes.
217 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
218 temporary file for that.
221 Chunked files transmission appeared with corresponding
222 @command{nncp-reass} command and @option{freqchunked} configuration file
223 entry. Useful for transferring big files over small storage devices.
226 @option{freqminsize} configuration file option, analogue to
227 @option{-minsize} one.
230 @command{nncp-xfer}'s @option{-force} option is renamed to
231 @option{-mkdir} for clarity.
234 @option{-minsize} option is specified in KiBs, not bytes, for
238 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
239 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
240 common prefix and are grouped together for convenience.
243 @command{nncp-cfgenc} command appeared, allowing configuration file
244 encryption/decryption, for keeping it safe without any either OpenPGP or
248 Cryptographic libraries (dependencies) are updated.
254 @item Small @command{nncp-rm} command appeared.
255 @item Cryptographic libraries (dependencies) are updated.
261 @item Trivial small fix in default niceness level of @command{nncp-file}
262 and @command{nncp-freq} commands.
268 @item Small fix in @command{nncp-call}, @command{nncp-caller},
269 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
271 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
272 shorter and more convenient to use.
273 @item @command{nncp-mincfg} command appeared: helper allowing to create
274 minimalistic stripped down configuration file without private keys,
275 that is useful during @command{nncp-xfer} usage.
280 Fixed compatibility with Go 1.6.
285 @item @strong{Incompatible} packet's format change (magic number is
286 changed too): size field is encrypted and is not send in plaintext
288 @item @option{-minsize} option gives ability to automatically pad
289 outgoing packets to specified minimal size.
290 @item @command{nncp-daemon} and
291 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
292 packets appearance in the background while connected. Remote side is
293 immediately notified.
294 @item @option{-onlinedeadline} option gives ability to configure timeout
295 of inactivity of online connection, when it could be disconnected. It
296 could be used to keep connection alive for a long time.
297 @item @option{-maxonlinetime} option gives ability to set maximal
298 allowable online connection aliveness time.
299 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
300 @item @command{nncp-pkt} command can decompress the data.
