+04Nov99=======================================================================
+1. Removed ~ from the end of the PC18.
+2. Removed a hangover from duff character checking in cluster.pl
+03Nov99=======================================================================
+1. Simplified command caching so it uses anonymous subroutines, you should
+also get error messages back on the console now when developing.
+2. Allow locally connected AK1A clusters that for some obscure reason don't
+issue PC19s to still appear as connected and allow them to acquire users.
+31Oct99=======================================================================
+1. updated Minimuf.pm and show/muf.pl to the fixed versions sent to me by
+Steve Franke K9AN.
+2. Made set/badnodes work, added show/badnodes. This is an interim fix until
+input spot filtering works.
+24Oct99=======================================================================
+1. fixed announces so that nodes only get one of them (not two).
+2. Altered the select timeouts to prevent apparent excessive CPU usage on
+multiprocessor machines (or at least that is what seems to be the trouble
+here).
+22Oct99=======================================================================
+1. allow filter CALLSIGNS to be in upper or lower case.
+2. create the concept of input and output filters, input filters are of the
+form "in_$call.pl" eg: "in_g1tlh.pl" (or "in_G1TLH.pl"), output filters are
+"g1tlh.pl" (or "G1TLH.pl").
+3. all users can now filter on spots, ann and wwv (assuming the sysop has set
+the filters up - still no user creatable filters. Nodes can filter on both
+input for announces and output for all of these. I would recommend setting
+up a few filters that are likely to be wanted and then symlinking callsigns
+to them as you get requests.
+4. added callsign and length of history/position of screen stats to console.
+If you want to change the colour of the callsign you will need to copy the
+Console.pm to your /spider/local directory and change the $mycallcolor equate.
+21Oct99=======================================================================
+1. fixed reply so that reply b or reply nop generate a bulletin with the
+correct address.
+2. implemented sh/muf command.
+3. reduced privilege of catchup and uncatchup to 5. This so that, suitably
+privileged, nodes that occasionally link can rcmd a "catchup <nodecall> all"
+to the node they are connecting to and thus prevent a large tranche of,
+potentially duplicate, mail. This isn't an issue for DXSpider, but may be
+an issue for any AK1A clusters you are connected to.
+20Oct99=======================================================================
+1. Translated all the subroutines of minimuf into perl as Minimuf.pm
+2. Limited the length of an ANN that is saved for de-duping to $pc12_dup_lth
+(def 72)
+3. help command should now return stuff that you expect.
+4. reduced necessary privilege to use 'MSG' command to 6.
+5. Correct the count of spots and wwv for a merge.
+6. Allow decodes of DK0WCY-3 WWV data beacon announces
+7. rewrote send so that an SB doesn't send a buckshee bull to NOPRIVATE!
+8. Changed default colouration on console so that all spots >= 50Mhz are red
+9. Fixed init command so that PC21s are sent down non-initted channels
+10. Allow forwarding of unknown private mail. This means that you can set up
+forwarding of 'foreign' mail across to and by gateways using the same
+mechanism as bulletins (/spider/msg/forward.pl).
+11. Allow line wrapping on the console (G0RDI, G0VGS et al).
+18Oct99=======================================================================
+1. changed help command so that it works correctly with multiple title lines.
+2. added to address to the list of things a message checks to see whether it
+is a duplicate (how on earth did it take _this_ long to find this one?).
+3. Changes S CC so that the callsign it says it has sent to is the real one
+(request from G8TIC)
+21Sep99=======================================================================
+1. allow zero messages to be stored (request from G4PDQ)
+2. make DX more flexible and change spotter syntax to be consistant with
+sh/dx (request from K9AN)
+30Aug99=======================================================================
+1. remove -@ as well as \d from SSIDs for spots
+2. remove WEB and/or NET from the front or rear of callsigns in Prefix.pm
+29Aug99=======================================================================
+1. Added msg command to allow the changing of To, From, Subject and so on the
+messages. This seems particularly important just now as a whole raft of G3's
+seem to be putting out non private bulls to callsigns.
+2. While I am at set messages to TO fields that appear to be users to private
+if they have been sent as bulls.
+3. Add DISTROs, if a callsign field appears in /spider/msg/distro in upper
+use that as a list of callsigns to send further. Note this is potentially
+recursive as callsigns in a distro can be distros.
+25Aug99=======================================================================
+1. check the date of a WWV much more carefully.
+24Aug99=======================================================================
+1. Prevented spots with lowercase callsigns being forwarded. This opens a
+much bigger can of worms which I shall have to address later.
+17Aug99=======================================================================
+1. all protocol except PC29 containing %XX characters will be dumped.
+2. Changed console.pl so that if you start typing it moves the top window
+back to the bottom.
+19Jul99=======================================================================
+1. Added iota and qra clauses to sh/dx as well, these take optional arguments
+and will look for the appropriate strings.
+17Jul99=======================================================================
+1. Started database integration.
+2. added qsl clause to sh/dx that searches for qsl or via in the dx info
+16Jul99=======================================================================
+1. drop frames with 'illegal' characters in them (but pass frames with
+embedded %XX characters).
+15Jul99=======================================================================
+1. Changed grepdbg to accept a regexp. More useful (to me anyway).
+2. Altered init command so that it doesn't send PC21s down the initted
+channel.
+10Jul99=======================================================================
+1. added an explicit disconnect from my side for already connected calls. This
+appears to have fixed a problem where if two consoles connect at the same time
+with the same (sysop?) callsign the cluster would stop.
+2. added some debugging in the Message handler to allow more state to be seen.
+3. Message handler now seems to work better for longer and doesn't spew out
+PC42 aborts with quite such gay abandon.
+05Jul99=======================================================================
+1. added stat/msg and stat/cluster commands to allow me to poke about inside
+the msg and cluster node tables.
+04Jul99=======================================================================
+1. removed silly 'new message has arrived' to connected nodes
+2. added a ! command to the console.pl program; works like the bash shell.
+01Jul99=======================================================================
+1. Altered priv to 5 for connect.pl to match disconnect for nodes
+29Jun99=======================================================================
+1. fixed merge command that I broke.
+2. added some randomness in waittimes for aborted outgoing messages
+3. Message Queuing now only occurs every 5 minutes (configurable if anyone
+wants to write the command for doing it) and on receipt of a PC16. This is
+a further attempt at sorting the crossing of messages!
+4. a PC33 will cause another attempt at queuing. If you are on a roll, keep
+going!
+28Jun99=======================================================================
+1. console.pl now works with history and editting.
+2. added scrolling to stuff sent by the cluster.
+3. added colours to things.
+27Jun99=======================================================================
+1. added WWV filtering
+2. added timeouts to for forwarding Messages, also added a waiting time for
+failed (stalled) outgoing messages.
+3. Incoming messages will now have priority over outgoing messages to the
+same node.
+4. Added 'catchup' command which will 'catchup' messages to date for a node.
+This means that when you start forwarding to a node, it doesn't get all the
+messages queued up that are probably old.
+5. added 'uncatchup' which does the opposite of the above.
+6. fixed kill full and PC49 handling so that it actually works.
+7. Fixed local aliases so they add to the front of the standard ones. This
+means you only need to add your specials or override the system ones you need
+to.
+21Jun99=======================================================================
+1. changed regex for cluster->client msgs so that strings like |---| are no
+longer ignored.
+20Jun99=======================================================================
+1. prevented a merge to myself (causes a loop)
+18Jun99=======================================================================
+1. fixed a problem with DXLogPrint repeating log entries.
+2. altered the permissions on disconnnect so that priv 5 users can disconnect
+clusters, but still require priv 8 to disconnect users.
+3. made sure that an incoming PC18 clears out all the cluster info for
+that channel before re-initialising.
+4. add init command.
+5. disconnect users before nodess on shutdown
+15Jun99=======================================================================
+1. added grepdbg program (so you can search your debug files and get times
+and dates of incidents).
+2. Moved DXVars.pm to DXVars.pm.issue to force new users to cp it to their
+local directory.
+3. added $allowzero to DXProt to allow thru PC19s with zero protocol versions.
+14Jun99=======================================================================
+1. changed IO::File in help and apropos to IO::File
+2. added a check for isa('DXNode') for PC50s
+08Jun99=======================================================================
+1. Started work on the curses based operator console.
+03Jun99=======================================================================
+1. cluster seems to have a memory leak, put DESTROY functions in where
+appropriate.
+2. try to make sure that PC21 commands are not issued inappropriately and
+also reformat PC19 for onward broadcast so that nodes coming in on loops are
+dropped from those broadcasts.
+3. make sure PC16,17,19,21 doen't affect locally connected nodes.
+4. Changed all instances of FileHandle to IO::File.
