+1. Fix odd (and old) regression dx command (line ending 59+++) '++' being the
+ culprit.
+06Mar23=======================================================================
+1. Fix filter error reporting, including incrementing concurrent error count
+ if there are actually any detected parse errors.
+2. Fix warnings on difft.
+3. Add the origin of any incoming SP if it is emailed to the recipient.
+4. Oops I accidently restored one path of the node being disconnected that I
+ fixed below (because of changes to filtering).
+04Mar23=======================================================================
+1. Fixed regression caused by too many command errors in (startup) script
+ files. This is caused by much stricter checking of commands entered both
+ by users AND scripts. If there more concurrent errors ie. greater than
+ $DXChannel::maxerrors (default 10) then that user will be disconnected.
+
+ Unfortunately this could include the $mycall (node) channel if there were
+ too many command users in the startup script. The example I looked at had
+ a load of HTML pasted into it.
+
+ For various reasons the only manifestation of this problem was that pings
+ no longer worked.
+
+ This has been fixed. I am grateful to Fulvio HB9DHG for letting me break
+ his node for an hour or so until I worked out what was going on.
+03Mar23=======================================================================
+1. Fix DXDebug::DXDebug not found errors in rarely used functions. This is
+ also an interaction with differing versions of Mojolicious. Clearly this
+ has never happened to me (sigh).
+2. Allow non-privileged users to use ping (no arguments) and get 'PONG nn'
+ where nn is an incrementing counter or if there is an argument it will
+ return 'PONG <argument>' - all in UPPER CASE. See help ping for more
+ details.
+02Mar23=======================================================================
+1. Fix sh/dx/30 problem. I.e. allow old style version of sh/dx 30.
