10 @strong{Incompatible} @emph{bundle} archive format changes and
11 @command{nncp-bundle} workability with Go 1.10+. Bundles must be
12 valid tar archives, but Go 1.9 made them invalid because of long paths
13 inside. NNCP accidentally was dependant on that bug. Explicit adding of
14 @file{NNCP/} directory in archive restores workability with valid tar
22 Ability to disable relaying at all using @verb{|-via -|} command line option.
29 @strong{Incompatible} plain packet format changes. Older versions are
32 Ability to queue remote command execution, by configuring @option{exec}
33 option in configuration file and using @command{nncp-exec} command:
36 @command{nncp-mail} command is replaced with more flexible
37 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
38 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
40 @option{sendmail} configuration file option is replaced with
41 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
42 @verb{|exec: sendmail: [...]|}.
45 Ability to override @option{via} configuration option for destination
46 node via @option{-via} command line option for following commands:
47 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
49 Chunked files, having size less than specified chunk size, will be sent
50 as an ordinary single file.
52 Exec commands are invoked with additional @env{NNCP_NICE} and
53 @env{NNCP_SELF} environment variables.
55 Files, that are sent as a reply to freq, have niceness level taken from
56 the freq packet. You can set desired niceness during @command{nncp-freq}
57 invocation using @option{-replynice} option.
59 @command{nncp-toss} command can ignore specified packet types during
60 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
63 @command{nncp-file} command uses
64 @option{FreqMinSize}/@option{FreqChunked} conifiguration file options
65 for @option{-minsize}/@option{-chunked} by default. You can turn this
66 off by specifying zero value.
73 @strong{Incompatible} encrypted/eblob packet format changes. Older
74 versions are not supported.
76 Twofish encryption algorithm is replaced with ChaCha20. It is much more
77 faster. One cryptographic primitive less.
79 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
80 another cryptographic primitive less (assuming that BLAKE2X is nearly
88 @strong{Incompatible} encrypted packet format changes. Older versions
91 @command{nncp-bundle} command can either create stream of encrypted
92 packets, or digest it. It is useful when dealing with stdin/stdout based
93 transmission methods (like writing to CD-ROM without intermediate
94 prepared ISO image and working with tape drives).
96 @command{nncp-toss} is able to create @file{.seen} files preventing
97 duplicate packets receiving.
99 Single background checksum verifier worker is allowed in
100 @command{nncp-call}. This is helpful when thousands of small inbound
101 packets could create many goroutines.
103 Ability to override path to spool directory and logfile through either
104 command line argument, or environment variable.
106 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
107 @file{.part}, @file{.lock} and temporary files.
111 @section Release 0.12
114 Sendmail command is called with @env{NNCP_SENDER} environment variable.
118 @section Release 0.11
121 @command{nncp-stat}'s command output is sorted by node name.
125 @section Release 0.10
128 @command{nncp-freq}'s @file{DST} argument is optional now. Last
129 @file{SRC} path's element will be used by default.
136 Fix @option{-rx}/@option{-tx} arguments processing in
137 @command{nncp-call} command. They were ignored.
144 Little bugfix in @command{nncp-file} command, where @option{-minsize}
145 option for unchunked transfer was not in KiBs, but in bytes.
152 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
153 temporary file for that.
156 Chunked files transmission appeared with corresponding
157 @command{nncp-reass} command and @option{freqchunked} configuration file
158 entry. Useful for transferring big files over small storage devices.
161 @option{freqminsize} configuration file option, analogue to
162 @option{-minsize} one.
165 @command{nncp-xfer}'s @option{-force} option is renamed to
166 @option{-mkdir} for clarity.
169 @option{-minsize} option is specified in KiBs, not bytes, for
173 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
174 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
175 common prefix and are grouped together for convenience.
178 @command{nncp-cfgenc} command appeared, allowing configuration file
179 encryption/decryption, for keeping it safe without any either OpenPGP or
183 Cryptographic libraries (dependencies) are updated.
189 @item Small @command{nncp-rm} command appeared.
190 @item Cryptographic libraries (dependencies) are updated.
196 @item Trivial small fix in default niceness level of @command{nncp-file}
197 and @command{nncp-freq} commands.
203 @item Small fix in @command{nncp-call}, @command{nncp-caller},
204 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
206 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
207 shorter and more convenient to use.
208 @item @command{nncp-mincfg} command appeared: helper allowing to create
209 minimalistic stripped down configuration file without private keys,
210 that is useful during @command{nncp-xfer} usage.
215 Fixed compatibility with Go 1.6.
220 @item @strong{Incompatible} packet's format change (magic number is
221 changed too): size field is encrypted and is not send in plaintext
223 @item @option{-minsize} option gives ability to automatically pad
224 outgoing packets to specified minimal size.
225 @item @command{nncp-daemon} and
226 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
227 packets appearance in the background while connected. Remote side is
228 immediately notified.
229 @item @option{-onlinedeadline} option gives ability to configure timeout
230 of inactivity of online connection, when it could be disconnected. It
231 could be used to keep connection alive for a long time.
232 @item @option{-maxonlinetime} option gives ability to set maximal
233 allowable online connection aliveness time.
234 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
235 @item @command{nncp-pkt} command can decompress the data.
