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