I should have mentioned that the version is always available
in the HTTP Server header, for example:

     MythTV/0.28-pre-3094-g349d3a4 Linux/3.13.0-66-generic UPnP/1.0

and

     Linux 3.13.0-65-generic, UPnP/1.0, MythTV 0.27.20150622-1

ChannelID.

It calls ChannelUtil::UpdateChannel:

     https://code.mythtv.org/cgit/mythtv/tree/mythtv/libs/libmythtv/channelutil.cpp#n1559

and down on line 1590 is the WHERE chanid= line. Also note 1591-6 for fields
that won't be updated if they're not passed. Makes life a tad simpler.
Be careful not to use the IconURL in the Get to set the Icon in the
Update.

Another handy POST endpoint: Myth/BackupDatabase
