10 @strong{Incompatible} plain packet format changes. Older versions are
13 Ability to queue remote command execution, by configuring @option{exec}
14 option in configuration file and using @command{nncp-exec} command:
17 @command{nncp-mail} command is replaced with more flexible
18 @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
19 you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
21 @option{sendmail} configuration file option is replaced with
22 @option{exec}. @verb{|sendmail: [...]|} must be replaced with
23 @verb{|exec: sendmail: [...]|}.
26 Ability to override @option{via} configuration option for destination
27 node via @option{-via} command line option for following commands:
28 @command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
30 Chunked files, having size less than specified chunk size, will be sent
31 as an ordinary single file.
33 Exec commands are invoked with additional @env{NNCP_NICE} and
34 @env{NNCP_SELF} environment variables.
36 Files, that are sent as a reply to freq, have niceness level taken from
37 the freq packet. You can set desired niceness during @command{nncp-freq}
38 invocation using @option{-replynice} option.
40 @command{nncp-toss} command can ignore specified packet types during
41 processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
44 @command{nncp-file} command uses
45 @option{FreqMinSize}/@option{FreqChunked} conifiguration file options
46 for @option{-minsize}/@option{-chunked} by default. You can turn this
47 off by specifying zero value.
54 @strong{Incompatible} encrypted/eblob packet format changes. Older
55 versions are not supported.
57 Twofish encryption algorithm is replaced with ChaCha20. It is much more
58 faster. One cryptographic primitive less.
60 HKDF-BLAKE2b-256 KDF algorithm is replaced with BLAKE2Xb XOF. Yet
61 another cryptographic primitive less (assuming that BLAKE2X is nearly
69 @strong{Incompatible} encrypted packet format changes. Older versions
72 @command{nncp-bundle} command can either create stream of encrypted
73 packets, or digest it. It is useful when dealing with stdin/stdout based
74 transmission methods (like writing to CD-ROM without intermediate
75 prepared ISO image and working with tape drives).
77 @command{nncp-toss} is able to create @file{.seen} files preventing
78 duplicate packets receiving.
80 Single background checksum verifier worker is allowed in
81 @command{nncp-call}. This is helpful when thousands of small inbound
82 packets could create many goroutines.
84 Ability to override path to spool directory and logfile through either
85 command line argument, or environment variable.
87 @command{nncp-rm} is able to delete outbound/inbound, @file{.seen},
88 @file{.part}, @file{.lock} and temporary files.
95 Sendmail command is called with @env{NNCP_SENDER} environment variable.
102 @command{nncp-stat}'s command output is sorted by node name.
106 @section Release 0.10
109 @command{nncp-freq}'s @file{DST} argument is optional now. Last
110 @file{SRC} path's element will be used by default.
117 Fix @option{-rx}/@option{-tx} arguments processing in
118 @command{nncp-call} command. They were ignored.
125 Little bugfix in @command{nncp-file} command, where @option{-minsize}
126 option for unchunked transfer was not in KiBs, but in bytes.
133 Ability to feed @command{nncp-file} from stdin, that uses an encrypted
134 temporary file for that.
137 Chunked files transmission appeared with corresponding
138 @command{nncp-reass} command and @option{freqchunked} configuration file
139 entry. Useful for transferring big files over small storage devices.
142 @option{freqminsize} configuration file option, analogue to
143 @option{-minsize} one.
146 @command{nncp-xfer}'s @option{-force} option is renamed to
147 @option{-mkdir} for clarity.
150 @option{-minsize} option is specified in KiBs, not bytes, for
154 @command{nncp-newcfg} command is renamed to @command{nncp-cfgnew},
155 and @command{nncp-mincfg} to @command{nncp-cfgmin} -- now they have
156 common prefix and are grouped together for convenience.
159 @command{nncp-cfgenc} command appeared, allowing configuration file
160 encryption/decryption, for keeping it safe without any either OpenPGP or
164 Cryptographic libraries (dependencies) are updated.
170 @item Small @command{nncp-rm} command appeared.
171 @item Cryptographic libraries (dependencies) are updated.
177 @item Trivial small fix in default niceness level of @command{nncp-file}
178 and @command{nncp-freq} commands.
184 @item Small fix in @command{nncp-call}, @command{nncp-caller},
185 @command{nncp-daemon}: they can segmentation fail sometimes (no data is
187 @item @command{nncp-newnode} renamed to @command{nncp-newcfg} -- it is
188 shorter and more convenient to use.
189 @item @command{nncp-mincfg} command appeared: helper allowing to create
190 minimalistic stripped down configuration file without private keys,
191 that is useful during @command{nncp-xfer} usage.
196 Fixed compatibility with Go 1.6.
201 @item @strong{Incompatible} packet's format change (magic number is
202 changed too): size field is encrypted and is not send in plaintext
204 @item @option{-minsize} option gives ability to automatically pad
205 outgoing packets to specified minimal size.
206 @item @command{nncp-daemon} and
207 @command{nncp-call}/@command{nncp-caller} always check new @emph{tx}
208 packets appearance in the background while connected. Remote side is
209 immediately notified.
210 @item @option{-onlinedeadline} option gives ability to configure timeout
211 of inactivity of online connection, when it could be disconnected. It
212 could be used to keep connection alive for a long time.
213 @item @option{-maxonlinetime} option gives ability to set maximal
214 allowable online connection aliveness time.
215 @item @command{nncp-caller} command appeared: cron-ed TCP daemon caller.
216 @item @command{nncp-pkt} command can decompress the data.
