+@command{nncp-exec} has @option{-use-tmp} and @option{-nocompress}
+options now. Uncompressed packets are not compatible with previous NNCP
+versions.
+
+@item
+@command{nncp-call}, @command{nncp-caller} and @command{nncp-daemon} commands
+have @option{-autotoss*} options for running tosser after call is ended.

+Finish all SP protocol related goroutines, less memory leak.
+
+@item
+SP protocol generates less socket write calls, thus generating less TCP
+packets.
+
+@item
+Check @option{onlinedeadline} and @option{maxonlinetime} options every
+second, independently from socket reads (up to 10 seconds).
+
+@item
+Once per minute, if no other traffic exists, PING packets are sent in
+SP-connection. That allows faster determining of connection unworkability.

+@command{nncp-toss} uses lock-file to prevent simultaneous tossing.
