+- Fix leak in session freelist when initial RADIUS session allocation
+ fails.
+- Don't process C_LASTSEEN unless we're a master (otherwise a crashed
+ master kills all slaves once restarted).
+- Make "show running-config" a privileged command (contains clear text
+ shared secrets).
+- Add sessionctl plugin to provide drop/kill via nsctl.
+- Add handling of "throttle=N" RADIUS attributes.
+- Fix RADIUS indexing (should have 16K entries with 64 sockets).
