    Fixed problem when a LNet device is disconnected, the fault status was not stable.
    Fixed problem where device fault was reported for a few seconds when the manager was disconnected.
    Fixed a problem where network faults were reported for some time after startup.
    Fixed a problem where live audio is interrupted every couple of seconds when the gnet ring is broken.
    Fixed some situations where reconnecting the Gnet cable still kept the remote fault status active on some devices.
    Fixed a problem where events could not be started when the gnet monitoring was turned off and the gnet ring was broken.
    Fixed a problem where line faults where reported on the C500, while the monitoring was turned off and a sw6 was connected.
    Fixed a problem that could cause a cpu fault, when a large number of zones was activated at the same time.
    Fixed a problem with zone state activation when Lnet devices from a remote master were disconnected.
    Fixed a problem where the C500 bridged amplifier in combination with the Sw6 only had half the expected voltage.
    Improved scanning of devices via manager. (Old versions of the manager will no longer be able to find the devices with this firmware. Only this or a newer version of the manager will work)
    
4Evac Manager Version 5.3K
    Added "class A wiring" setting to SW6 devices. This means that each pair of outputs is used as a loop.
    Added "Keep general fault status until reset" general setting. This makes sure the fault state stays active in the system, even when the fault itself is gone already (This function will only activate 100 seconds after startup).
    Fixed deactivation of lamp test on the expander device from the C500 device. It could stay on with some button combination.
    Fixed a problem where the SW6 was not activating messages after a C500 device had a mains fault.
    
4Evac Manager Version 5.4
    Added initial support for maze devices
    Added a new device type: AM448 that should be used with maze amplifiers, instead of the SW6.
    Added fallback method for the network bootloader in network bootloader V1.8 to force a device to the bootloader mode. This uses the USB bootloader detection.
    Added files to upgrade a network bootloader to a newer version of the network bootloader.
    Added confirmation message in the network flasher and network bootloader flasher for the number of found devices.
    
    Removed general message 17, this is replaced to support maze zone functions.
            
    Fixed a problem with touchscreen sometimes giving a long beep on user actions.
    Fixed a problem with partially rejected zone settings. This was not processed properly on touchscreen devices.
    Fixed a problem with activation of zones when the touchscreen IFM was used. It would not always return the proper zone state after the IFM was deactivated.        
    Fixed a problem with activation of events and zone syncing from LNet devices.
    Fixed a problem with activation of events and zone syncing when the event was triggered from a remote device.
    Fixed a problem where some devices could remove zone faults when stopping zone states
    Fixed some problems with event triggering via inputs after reboot of the system.
    Fixed a problem where a message with a limited number of playbacks would not continue playing if the input stayed active.     
    Fixed a problem with impact amplifier communication after a reboot.            
    Fixed a problem with reading calibration values for the C500 after a reboot.                  
    Fixed a problem where LNet devices sometimes show a gnet fault in the live monitoring.
    Fixed a problem where GPIO gpo connections were removed incorrectly when the gpio device was edited.
    Fixed a problem where editing C500 evac input settings could clear C500 gpi input settings.
    Fixed a problem where some input functions could not be selected based on the connected event ids.
    Fixed a problem where the SW6 output settings where not loaded properly when it was an uneven column (only when class a wiring was unchecked)
    Fixed a problem where the network flasher and network bootloader flasher could not recognize the binaries when the filepath included some special characters.
    
    Updated version names for usb and network bootloaders, so live monitoring can show what kind of bootloader a device has. firmware ending with _U is USB and firmware ending with _N is NETWORK bootloader.
    Updated live monitoring for C500 and added a command to retrieve stored impedance values.
    Extended time for reboot indication (power led blinking) so it more closely matches the time needed for the system to start.
    
4Evac Manager Version 5.4A (Only the Controller, AM448 and the Manager software are changed when compared with version 5.4) 
    Fixed a problem with amplifier version fault after startup. Sometimes version number was not received properly and the system would stay in fault status. This could happen more frequently with a bigger system.
    Fixed a problem where maze amplifier could be selectable as speakerline when used as backup amp. (this should not be allowed)
    Fixed a problem where maze amplifier charger group was not saved properly.
    Fixed a problem with editing output connections. All options were deselected when select all was used followed by deselection of 1 or more checkboxes.
    Updated device ids in the generated text file. It should show the hex id in the text file instead of the decimal number.
