+1. Make sure than *every* channel has an IP address. Thank you (I think) Kin
+ for pointing out that PC92 A records were not going out with IP addresses.
+ I'm guessing that other things (like spots) had a similar problem.

+1. Fix strange errors for carp on missing route_*_cache files on startup.
+14Jan23=======================================================================
+1. Fixed route PC11 promotions so that a new PC61 is actually generated and
+ also sent instead of the original PC11 (to PC61 capable nodes).
+13Jan23=======================================================================
+1. Periodically store Routing tables and, if they are young enough (def: 3hrs)
+ autotically restore them on restart of the node. This will short circuit
+ the need to rebuild the routing tables from scratch on every restart -
+ which is normally for something like software update.
+2. Fix pc11 debugging stats with the correct figures. Sigh... Also move some
+ of the totals to a different place.
+3. Add show/spotstats command which gives the current spot statistics shown
+ during pc11 debugging (which means you don't need to set/deb pc11 unless
+ you really want that extra noise).
+12Jan23=======================================================================
+1. Regularise 'set/debug pc11' output to track all the routes through PC11 and
+ PC61 processing and statistics.
