+@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.

+@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.

+@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.
