+08Jun20=======================================================================
+1. Fix show/mydx (lack of) filtering bug.
+2. Add qra locator to prefix_data.pl.
+3. Add 4 digit qra square for spotted callsign if show/dxgrid is enabled.
+4. Fix general filtering bug where erroneous input causes crashing.
+03Jun20=======================================================================
+1. Make sure that all possible regexes get passed across to the search engine.
+2. Fix out of order logging on sh/log queries spanning more than one month.
+3. Do not read backwards on sh/dx, reading forwards seems a 1/3 quicker.
+4. Add <ms>, <tr> and <es> shortcuts to sh/dx (e.g sh/dx <tr> on 2m).
+02Jun20=======================================================================
+1. Fix the small whoopsie in sh/dx.
+01Jun20=======================================================================
+1. Fix sh/dx iota and qra. This completes the conversion of sh/dx's limited
+ "old style" parsing to using Filter style parsing with something that
+ allows expressions include brackets ( and ) as well as the 'not' keyword.
+ NOTE: the precedence rules are the same as perl's '!', '||' and '&&'
+ operators.
+31May20=======================================================================
+1. Improve links command layout slightly.
+2. Issue an *accurate* UPGRADE.mojo with all the new packages included!
+3. Fix issue with sh/dx
+30May20=======================================================================
+1. Fix sh/dx! It appears that there is a long standing problem with sh/dx not
+ actually return all the answers it should. I have also had a request to
+ allow / enable the "not" keyword (just like the filtering system dones).
+
+ Now this was one of the earliest modules that I wrote and it took quite
+ a bit of work to tease out the important bits and then use the Filter
+ module (as in acc/spot) to generate the sh/dx filtering expressions. This
+ seems to have been done.
+
+ NB This will likely not work if you are using a SQL backend to do sh/dx
+ commands. This was never actually an official feature. It is now
+ deprecated.
+29May20=======================================================================
+1. Please install Math::Round and Data::Structure::Util. Instructions are
+ available in UPGRADE.mojo.
+2. ** Withdrawn ** user file format change to json not yet committed.
+20May20=======================================================================
+1. Backport convert-users-v3-to-v4.pl to allow creation of the new json
+ formatted *text* based user file from the old v3 DB_File and Storable
+ version. This can be done either online (with the node running) or offline
+ with the node stopped. This is in preparation for the next update of the
+ mojo branch. Running this program just *BEFORE* doing your next update of
+ the mojo branch *should* ensure a seemless transition to the Storable &
+ DB_File free version of the users file.
+2. Show git branch in show/version.
+3. Add CTY-3010 changes.
+17May20=======================================================================
+1. Backport DXSubprocess to change serialisations.
+ Currently the internals of Mojo::IOLoop::Subprocess defaults to
+ using Storeable as its cross-process argument and data serialisaion
+ method. It can use others. This update reverts back to the
+ original ForkCall method of using JSON.
+10May20=======================================================================
+1. Added basic changes so that users *could* have multiple connections to the
+ same node if it is allowed. This is work in progress and is there to see
+ if it deals with some networking problems encountered on very high volume
+ sites which can see more than 1000 users (although the problems can occur
+ with many hundreds or by the practices of certain ISPs). More information
+ will be forthcoming if I get to the bottom of what's REALLY going on and
+ whether this is (or maybe just one part of) the solution. It won't be
+ ready for general use until then.
+2. Fixed the script import error reported by Joaquin (EA3CV?), by the simple
+ expedient of restoring the version from the master branch.
+09May20=======================================================================
+1. Show the route by which this PCxx came in progress debugging reports. In
+ some other words: the spot/wwv/wcy/ann message arrived first from this
+ connection.
+2. Improve progress WWV & WCY messages.
+3. Stop random node isolations (at least in one place)
+08May20=======================================================================
+1. Tidy up routing table
+2. Add new argument to show/version (ALL or list of regexes) that allow you
+ to see the version and build nos of all nodes on the system.
+07May20=======================================================================
+1. Revert changes made since 25Apr concerning IP address reconciliation.
+25Apr20=======================================================================
+1. Add maximum no of users on node to show/cluster.
+2. Add ability to show last n lines of debugging ring buffer.
+3. Remove redundant wpxloc.dat file.
+24Apr20=======================================================================
+1. Add 'progress' debugging for showing that stuff is happening in nologchan
+ a.k.a ringbuffer only mode.
+2. Fix grepdbg so that no regex argument simply lists the file.
+3. Add CTY-3008 prefixes.
+22Apr20=======================================================================
+1. Fix the module search path in update_sysop.pl
+2. Add latest prefixes CTY-3007
+3. Fix unset/startup command. This will only work for users' start up scripts
+ things like user_default or startup must be edited or removed by hand.
+21Apr20=======================================================================
+1. Finally fix the "actually tranmit" any output (like from 'logout' files)
+ to users before disconnecting. This also means that disconnecting nodes
+ now receive the (totally redundant, but hey) PC39 reason for disconnection.
+20Apr20=======================================================================
+1. Speed up sh/log (including chat, rcmd, ann etc) that search the system
+ log files, by removing a completely redundant subsystem and also leveraging
+ the core operating system utility 'tac', if it's available.
+19Apr20=======================================================================
+1. The long haul that is the mojo branch has started up again. It's something
+ to do during this lockdown.
+2. The problems and instabilities around running commands that worked in
+ forked processes, when used other than by normally logged in users (e.g.
+ in the local crontab), have been fixed.
+3. If a /spider/local_data/logout file is present then its contents will be
+ sent to the user on logout.
+4. Add the ability to sh/dx origin or ip (address).
+5. Retire the use of the deprecated Mojo::IOLoop::ForkCall in favour of using
+ the supported equivalent in Mojolicious 7.26 and above. Which means you
+ will need to upgrade Mojo to at least the version. The current version is
+ 8.36 and is known to work.
10Sep19=======================================================================
1. Improve DXSql database filtering to exclude most via <locator> type
reports.
