10 @strong{Incompatible} encrypted and eblob packet format change: AEAD
11 encryption mode with 128 KiB blocks is used now, because previously
12 @command{nncp-toss} did not verify encrypted packet's MAC before feeding
13 decrypted data to external command. Older versions are not supported.
15 Available free space checking before copying in @command{nncp-xfer},
16 @command{nncp-daemon}, @command{nncp-call(er)}.
18 @command{nncp-call} has ability only to listen packets on remote node,
19 without its transmission.
21 Dependant libraries are updated.
30 @command{nncp-daemon} can be run as @command{inetd}-service.
37 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
38 if @file{.seen} exists and treat it like file was already downloaded.
39 Possibly it was transferred out-of-bound and remote side needs to be
42 If higher priority packet is spooled, then @command{nncp-daemon} will
43 queue its sending first, interrupting lower priority transmissions.
45 Simple packet rate limiter added to online-related tools
46 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
48 Ability to specify niceness with symbolic notation:
49 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
51 Changed default niceness levels:
52 for @command{nncp-exec} from 64 to 96,
53 for @command{nncp-freq} from 64 to 160,
54 for @command{nncp-file} from 196 to 224.
61 @strong{Incompatible} @emph{bundle} archive format changes and
62 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
63 valid tar archives, but Go 1.9 made them invalid because of long paths
64 inside. NNCP accidentally was dependant on that bug. Explicit adding of
65 @file{NNCP/} directory in archive restores workability with valid tar
73 Ability to disable relaying at all using @verb{|-via -|} command line option.
80 @strong{Incompatible} plain packet format changes. Older versions are
83 Ability to queue remote command execution, by configuring @option{exec}
84 option in configuration file and using @command{nncp-exec} command:
87 @command{nncp-mail} command is replaced with more flexible
88 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
89 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
91 @option{sendmail} configuration file option is replaced with
92 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
93 @verb{|exec: sendmail: [...]|}.
96 Ability to override @option{via} configuration option for destination
97 node via @option{-via} command line option for following commands:
98 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
100 Chunked files, having size less than specified chunk size, will be sent
101 as an ordinary single file.
103 Exec commands are invoked with additional @env{NNCP_NICE} and
104 @env{NNCP_SELF} environment variables.
106 Files, that are sent as a reply to freq, have niceness level taken from
107 the freq packet. You can set desired niceness during @command{nncp-freq}
108 invocation using @option{-replynice} option.
110 @command{nncp-toss} command can ignore specified packet types during
111 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
114 @command{nncp-file} command uses
115 @option{FreqMinSize}/@option{FreqChunked} configuration file options
116 for @option{-minsize}/@option{-chunked} by default. You can turn this
117 off by specifying zero value.
124 @strong{Incompatible} encrypted/eblob packet format changes. Older
125 versions are not supported.
127 Twofish encryption algorithm is replaced with ChaCha20. It is much more
128 faster. One cryptographic primitive less.
130 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
131 another cryptographic primitive less (assuming that BLAKE2X is nearly
132 identical to BLAKE2).
139 @strong{Incompatible} encrypted packet format changes. Older versions
142 @command{nncp-bundle} command can either create stream of encrypted
143 packets, or digest it. It is useful when dealing with stdin/stdout based
144 transmission methods (like writing to CD-ROM without intermediate
145 prepared ISO image and working with tape drives).
147 @command{nncp-toss} is able to create @file{.seen} files preventing
148 duplicate packets receiving.
150 Single background checksum verifier worker is allowed in
151 @command{nncp-call}. This is helpful when thousands of small inbound
152 packets could create many goroutines.
154 Ability to override path to spool directory and logfile through either
155 command line argument, or environment variable.
157 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
158 @file{.part}, @file{.lock} and temporary files.
162 @section Release 0.12
165 Sendmail command is called with @env{NNCP_SENDER} environment variable.
169 @section Release 0.11
172 @command{nncp-stat}'s command output is sorted by node name.
176 @section Release 0.10
179 @command{nncp-freq}'s @file{DST} argument is optional now. Last
180 @file{SRC} path's element will be used by default.
187 Fix @option{-rx}/@option{-tx} arguments processing in
188 @command{nncp-call} command. They were ignored.
195 Little bugfix in @command{nncp-file} command, where @option{-minsize}
196 option for unchunked transfer was not in KiBs, but in bytes.
203 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
204 temporary file for that.
207 Chunked files transmission appeared with corresponding
208 @command{nncp-reass} command and @option{freqchunked} configuration file
209 entry. Useful for transferring big files over small storage devices.
212 @option{freqminsize} configuration file option, analogue to
213 @option{-minsize} one.
216 @command{nncp-xfer}'s @option{-force} option is renamed to
217 @option{-mkdir} for clarity.
220 @option{-minsize} option is specified in KiBs, not bytes, for
224 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
225 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
226 common prefix and are grouped together for convenience.
229 @command{nncp-cfgenc} command appeared, allowing configuration file
230 encryption/decryption, for keeping it safe without any either OpenPGP or
234 Cryptographic libraries (dependencies) are updated.
240 @item Small @command{nncp-rm} command appeared.
241 @item Cryptographic libraries (dependencies) are updated.
247 @item Trivial small fix in default niceness level of @command{nncp-file}
248 and @command{nncp-freq} commands.
254 @item Small fix in @command{nncp-call}, @command{nncp-caller},
255 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
257 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
258 shorter and more convenient to use.
259 @item @command{nncp-mincfg} command appeared: helper allowing to create
260 minimalistic stripped down configuration file without private keys,
261 that is useful during @command{nncp-xfer} usage.
266 Fixed compatibility with Go 1.6.
271 @item @strong{Incompatible} packet's format change (magic number is
272 changed too): size field is encrypted and is not send in plaintext
274 @item @option{-minsize} option gives ability to automatically pad
275 outgoing packets to specified minimal size.
276 @item @command{nncp-daemon} and
277 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
278 packets appearance in the background while connected. Remote side is
279 immediately notified.
280 @item @option{-onlinedeadline} option gives ability to configure timeout
281 of inactivity of online connection, when it could be disconnected. It
282 could be used to keep connection alive for a long time.
283 @item @option{-maxonlinetime} option gives ability to set maximal
284 allowable online connection aliveness time.
285 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
286 @item @command{nncp-pkt} command can decompress the data.
