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 Dependant libraries are updated.
27 @command{nncp-daemon} can be run as @command{inetd}-service.
34 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
35 if @file{.seen} exists and treat it like file was already downloaded.
36 Possibly it was transferred out-of-bound and remote side needs to be
39 If higher priority packet is spooled, then @command{nncp-daemon} will
40 queue its sending first, interrupting lower priority transmissions.
42 Simple packet rate limiter added to online-related tools
43 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
45 Ability to specify niceness with symbolic notation:
46 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
48 Changed default niceness levels:
49 for @command{nncp-exec} from 64 to 96,
50 for @command{nncp-freq} from 64 to 160,
51 for @command{nncp-file} from 196 to 224.
58 @strong{Incompatible} @emph{bundle} archive format changes and
59 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
60 valid tar archives, but Go 1.9 made them invalid because of long paths
61 inside. NNCP accidentally was dependant on that bug. Explicit adding of
62 @file{NNCP/} directory in archive restores workability with valid tar
70 Ability to disable relaying at all using @verb{|-via -|} command line option.
77 @strong{Incompatible} plain packet format changes. Older versions are
80 Ability to queue remote command execution, by configuring @option{exec}
81 option in configuration file and using @command{nncp-exec} command:
84 @command{nncp-mail} command is replaced with more flexible
85 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
86 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
88 @option{sendmail} configuration file option is replaced with
89 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
90 @verb{|exec: sendmail: [...]|}.
93 Ability to override @option{via} configuration option for destination
94 node via @option{-via} command line option for following commands:
95 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
97 Chunked files, having size less than specified chunk size, will be sent
98 as an ordinary single file.
100 Exec commands are invoked with additional @env{NNCP_NICE} and
101 @env{NNCP_SELF} environment variables.
103 Files, that are sent as a reply to freq, have niceness level taken from
104 the freq packet. You can set desired niceness during @command{nncp-freq}
105 invocation using @option{-replynice} option.
107 @command{nncp-toss} command can ignore specified packet types during
108 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
111 @command{nncp-file} command uses
112 @option{FreqMinSize}/@option{FreqChunked} configuration file options
113 for @option{-minsize}/@option{-chunked} by default. You can turn this
114 off by specifying zero value.
121 @strong{Incompatible} encrypted/eblob packet format changes. Older
122 versions are not supported.
124 Twofish encryption algorithm is replaced with ChaCha20. It is much more
125 faster. One cryptographic primitive less.
127 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
128 another cryptographic primitive less (assuming that BLAKE2X is nearly
129 identical to BLAKE2).
136 @strong{Incompatible} encrypted packet format changes. Older versions
139 @command{nncp-bundle} command can either create stream of encrypted
140 packets, or digest it. It is useful when dealing with stdin/stdout based
141 transmission methods (like writing to CD-ROM without intermediate
142 prepared ISO image and working with tape drives).
144 @command{nncp-toss} is able to create @file{.seen} files preventing
145 duplicate packets receiving.
147 Single background checksum verifier worker is allowed in
148 @command{nncp-call}. This is helpful when thousands of small inbound
149 packets could create many goroutines.
151 Ability to override path to spool directory and logfile through either
152 command line argument, or environment variable.
154 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
155 @file{.part}, @file{.lock} and temporary files.
159 @section Release 0.12
162 Sendmail command is called with @env{NNCP_SENDER} environment variable.
166 @section Release 0.11
169 @command{nncp-stat}'s command output is sorted by node name.
173 @section Release 0.10
176 @command{nncp-freq}'s @file{DST} argument is optional now. Last
177 @file{SRC} path's element will be used by default.
184 Fix @option{-rx}/@option{-tx} arguments processing in
185 @command{nncp-call} command. They were ignored.
192 Little bugfix in @command{nncp-file} command, where @option{-minsize}
193 option for unchunked transfer was not in KiBs, but in bytes.
200 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
201 temporary file for that.
204 Chunked files transmission appeared with corresponding
205 @command{nncp-reass} command and @option{freqchunked} configuration file
206 entry. Useful for transferring big files over small storage devices.
209 @option{freqminsize} configuration file option, analogue to
210 @option{-minsize} one.
213 @command{nncp-xfer}'s @option{-force} option is renamed to
214 @option{-mkdir} for clarity.
217 @option{-minsize} option is specified in KiBs, not bytes, for
221 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
222 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
223 common prefix and are grouped together for convenience.
226 @command{nncp-cfgenc} command appeared, allowing configuration file
227 encryption/decryption, for keeping it safe without any either OpenPGP or
231 Cryptographic libraries (dependencies) are updated.
237 @item Small @command{nncp-rm} command appeared.
238 @item Cryptographic libraries (dependencies) are updated.
244 @item Trivial small fix in default niceness level of @command{nncp-file}
245 and @command{nncp-freq} commands.
251 @item Small fix in @command{nncp-call}, @command{nncp-caller},
252 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
254 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
255 shorter and more convenient to use.
256 @item @command{nncp-mincfg} command appeared: helper allowing to create
257 minimalistic stripped down configuration file without private keys,
258 that is useful during @command{nncp-xfer} usage.
263 Fixed compatibility with Go 1.6.
268 @item @strong{Incompatible} packet's format change (magic number is
269 changed too): size field is encrypted and is not send in plaintext
271 @item @option{-minsize} option gives ability to automatically pad
272 outgoing packets to specified minimal size.
273 @item @command{nncp-daemon} and
274 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
275 packets appearance in the background while connected. Remote side is
276 immediately notified.
277 @item @option{-onlinedeadline} option gives ability to configure timeout
278 of inactivity of online connection, when it could be disconnected. It
279 could be used to keep connection alive for a long time.
280 @item @option{-maxonlinetime} option gives ability to set maximal
281 allowable online connection aliveness time.
282 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
283 @item @command{nncp-pkt} command can decompress the data.
