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 @command{nncp-call} has ability to download only specified packets.
23 Dependant libraries are updated.
32 @command{nncp-daemon} can be run as @command{inetd}-service.
39 @command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
40 if @file{.seen} exists and treat it like file was already downloaded.
41 Possibly it was transferred out-of-bound and remote side needs to be
44 If higher priority packet is spooled, then @command{nncp-daemon} will
45 queue its sending first, interrupting lower priority transmissions.
47 Simple packet rate limiter added to online-related tools
48 (@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
50 Ability to specify niceness with symbolic notation:
51 @verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
53 Changed default niceness levels:
54 for @command{nncp-exec} from 64 to 96,
55 for @command{nncp-freq} from 64 to 160,
56 for @command{nncp-file} from 196 to 224.
63 @strong{Incompatible} @emph{bundle} archive format changes and
64 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
65 valid tar archives, but Go 1.9 made them invalid because of long paths
66 inside. NNCP accidentally was dependant on that bug. Explicit adding of
67 @file{NNCP/} directory in archive restores workability with valid tar
75 Ability to disable relaying at all using @verb{|-via -|} command line option.
82 @strong{Incompatible} plain packet format changes. Older versions are
85 Ability to queue remote command execution, by configuring @option{exec}
86 option in configuration file and using @command{nncp-exec} command:
89 @command{nncp-mail} command is replaced with more flexible
90 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
91 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
93 @option{sendmail} configuration file option is replaced with
94 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
95 @verb{|exec: sendmail: [...]|}.
98 Ability to override @option{via} configuration option for destination
99 node via @option{-via} command line option for following commands:
100 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
102 Chunked files, having size less than specified chunk size, will be sent
103 as an ordinary single file.
105 Exec commands are invoked with additional @env{NNCP_NICE} and
106 @env{NNCP_SELF} environment variables.
108 Files, that are sent as a reply to freq, have niceness level taken from
109 the freq packet. You can set desired niceness during @command{nncp-freq}
110 invocation using @option{-replynice} option.
112 @command{nncp-toss} command can ignore specified packet types during
113 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
116 @command{nncp-file} command uses
117 @option{FreqMinSize}/@option{FreqChunked} configuration file options
118 for @option{-minsize}/@option{-chunked} by default. You can turn this
119 off by specifying zero value.
126 @strong{Incompatible} encrypted/eblob packet format changes. Older
127 versions are not supported.
129 Twofish encryption algorithm is replaced with ChaCha20. It is much more
130 faster. One cryptographic primitive less.
132 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
133 another cryptographic primitive less (assuming that BLAKE2X is nearly
134 identical to BLAKE2).
141 @strong{Incompatible} encrypted packet format changes. Older versions
144 @command{nncp-bundle} command can either create stream of encrypted
145 packets, or digest it. It is useful when dealing with stdin/stdout based
146 transmission methods (like writing to CD-ROM without intermediate
147 prepared ISO image and working with tape drives).
149 @command{nncp-toss} is able to create @file{.seen} files preventing
150 duplicate packets receiving.
152 Single background checksum verifier worker is allowed in
153 @command{nncp-call}. This is helpful when thousands of small inbound
154 packets could create many goroutines.
156 Ability to override path to spool directory and logfile through either
157 command line argument, or environment variable.
159 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
160 @file{.part}, @file{.lock} and temporary files.
164 @section Release 0.12
167 Sendmail command is called with @env{NNCP_SENDER} environment variable.
171 @section Release 0.11
174 @command{nncp-stat}'s command output is sorted by node name.
178 @section Release 0.10
181 @command{nncp-freq}'s @file{DST} argument is optional now. Last
182 @file{SRC} path's element will be used by default.
189 Fix @option{-rx}/@option{-tx} arguments processing in
190 @command{nncp-call} command. They were ignored.
197 Little bugfix in @command{nncp-file} command, where @option{-minsize}
198 option for unchunked transfer was not in KiBs, but in bytes.
205 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
206 temporary file for that.
209 Chunked files transmission appeared with corresponding
210 @command{nncp-reass} command and @option{freqchunked} configuration file
211 entry. Useful for transferring big files over small storage devices.
214 @option{freqminsize} configuration file option, analogue to
215 @option{-minsize} one.
218 @command{nncp-xfer}'s @option{-force} option is renamed to
219 @option{-mkdir} for clarity.
222 @option{-minsize} option is specified in KiBs, not bytes, for
226 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
227 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
228 common prefix and are grouped together for convenience.
231 @command{nncp-cfgenc} command appeared, allowing configuration file
232 encryption/decryption, for keeping it safe without any either OpenPGP or
236 Cryptographic libraries (dependencies) are updated.
242 @item Small @command{nncp-rm} command appeared.
243 @item Cryptographic libraries (dependencies) are updated.
249 @item Trivial small fix in default niceness level of @command{nncp-file}
250 and @command{nncp-freq} commands.
256 @item Small fix in @command{nncp-call}, @command{nncp-caller},
257 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
259 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
260 shorter and more convenient to use.
261 @item @command{nncp-mincfg} command appeared: helper allowing to create
262 minimalistic stripped down configuration file without private keys,
263 that is useful during @command{nncp-xfer} usage.
268 Fixed compatibility with Go 1.6.
273 @item @strong{Incompatible} packet's format change (magic number is
274 changed too): size field is encrypted and is not send in plaintext
276 @item @option{-minsize} option gives ability to automatically pad
277 outgoing packets to specified minimal size.
278 @item @command{nncp-daemon} and
279 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
280 packets appearance in the background while connected. Remote side is
281 immediately notified.
282 @item @option{-onlinedeadline} option gives ability to configure timeout
283 of inactivity of online connection, when it could be disconnected. It
284 could be used to keep connection alive for a long time.
285 @item @option{-maxonlinetime} option gives ability to set maximal
286 allowable online connection aliveness time.
287 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
288 @item @command{nncp-pkt} command can decompress the data.
