@itemize

+@strong{Incompatible} encrypted and eblob packet format change: AEAD
+encryption mode with 128 KiB blocks is used now, because previously
+@command{nncp-toss} did not verify encrypted packet's MAC before feeding
+decrypted data to external command. Older versions are not supported.
+@item
+Dependant libraries are updated.
+@item
+Minor bugfixes.

+@itemize
+@item
+@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller} check
+if @file{.seen} exists and treat it like file was already downloaded.
+Possibly it was transferred out-of-bound and remote side needs to be
+notifier about that.
+@item
+If higher priority packet is spooled, then @command{nncp-daemon} will
+queue its sending first, interrupting lower priority transmissions.
+@item
+Simple packet rate limiter added to online-related tools
+(@command{nncp-daemon}, @command{nncp-call}, @command{nncp-caller}).
+@item
+Ability to specify niceness with symbolic notation:
+@verb{|NORMAL|}, @verb{|BULK+10|}, @verb{|PRIORITY-5|}, etc.
+@item
+Changed default niceness levels:
+for @command{nncp-exec} from 64 to 96,
+for @command{nncp-freq} from 64 to 160,
+for @command{nncp-file} from 196 to 224.

+@itemize
+@item
+@strong{Incompatible} @emph{bundle} archive format changes and
+@command{nncp-bundle} workability with Go 1.10+. Bundles must be
+valid tar archives, but Go 1.9 made them invalid because of long paths
+inside. NNCP accidentally was dependant on that bug. Explicit adding of
+@file{NNCP/} directory in archive restores workability with valid tar
+archives.

+@strong{Incompatible} plain packet format changes. Older versions are
+not supported.
+@item
+Ability to queue remote command execution, by configuring @option{exec}
+option in configuration file and using @command{nncp-exec} command:
+ @itemize
+ @item
+ @command{nncp-mail} command is replaced with more flexible
+ @command{nncp-exec}. Instead of @verb{|nncp-mail NODE RECIPIENT|}
+ you must use @verb{|nncp-exec NODE sendmail RECIPIENT|}.
+ @item
+ @option{sendmail} configuration file option is replaced with
+ @option{exec}. @verb{|sendmail: [...]|} must be replaced with
+ @verb{|exec: sendmail: [...]|}.
+ @end itemize
+@item
Ability to override @option{via} configuration option for destination
node via @option{-via} command line option for following commands:
-@command{nncp-file}, @command{nncp-freq}, @command{nncp-mail}.
+@command{nncp-file}, @command{nncp-freq}, @command{nncp-exec}.
+@item
+Chunked files, having size less than specified chunk size, will be sent
+as an ordinary single file.
+@item
+Exec commands are invoked with additional @env{NNCP_NICE} and
+@env{NNCP_SELF} environment variables.
+@item
+Files, that are sent as a reply to freq, have niceness level taken from
+the freq packet. You can set desired niceness during @command{nncp-freq}
+invocation using @option{-replynice} option.
+@item
+@command{nncp-toss} command can ignore specified packet types during
+processing: @option{-nofile}, @option{-nofreq}, @option{-noexec},
+@option{-notrns}.
+@item
+@command{nncp-file} command uses
+@option{FreqMinSize}/@option{FreqChunked} configuration file options
+for @option{-minsize}/@option{-chunked} by default. You can turn this
+off by specifying zero value.
