1. Added all UPS status and setting datapoints available on the LCD to the RDU101 web-interface and SNMP/other protocols.
2. Added a new user-configurable alarm, "Replace Battery Soon", which can be set to alert the user 2, 3, or 4 months before the time the UPS calculates a new battery will be needed, allowing time for replacement batteries to be ordered.
3. Added the ability to adjust [Dischg protect time] and [Guaranteed Shutdown] settings on the CLI.
4. Improved the downloadable 'Event Log.csv' by replacing the catch-all "General Unspecified Event" with each UPS alarm as reported on the UPS LCD.

2020-10-12 RELEASE

FILES:
GXT5-MCU-V190-DSP-V190(500-3K)(LV,HV,I).bin

1. Enhanced the security of the firmware update procedure by using encrypted firmware files. This prevents the use of potentially non-authentic firmware.
2. Improved the [Max charge curr] setting to only show valid options for the installed UPS/EBC configuration.
3. Added the ability to change the LCD settings menu and maintenance menu passwords via the CLI.
4. Added the ability to execute a delayed shutdown from 0-999 seconds via the CLI.
5. Added Czech language option to the LCD.
6. Improved the fan performance by making the speed more stable and smoothing the transition between speeds.
7. Added the DSP firmware kernal version number to the LCD About tab.
8. Changed the setting name of [Temperature type] to [Temperature unit].
9. Changed the default temperature display from  C to  F for HV, MV, and LV models.
10. Increased the low line transfer point on GXT5-3KL620 and GXT5-3KL630 models from 160V to 176V to prevent the input breaker from tripping during a low-line condition at 105% load for an extended period of time.

2020-05-30 RELEASE

FILES:
GXT5-MCU-V180-DSP-V180(500-3K)(LV,HV,I).bin

1. Increased the power rating of the GXT5-3KL620RT2UXL from 2700W to 3000W.
2. Expanded the output voltage selections on the GXT5-3KL620RT2UXL and GXT5-3KL630RT2UXL models to 200/208/220/230/240VAC.
3. Changed the user setting and factory default value of [Guaranteed Shutdown] to "disabled" to reflect the use-case of the majority of customers. 
4. Changed the user setting and factory default value of [Battery Periodic Test] to "enabled" to allow automatic battery self checks.  The default interval for battery self checks is 8 weeks, but this can be changed in the settings menu.
5. Improved the behavior of [Any Mode Shutdown] by checking the state of the dry contacts during power up after a utility outage and return.  If the contacts are cleared during the outage, the UPS will now power back on automatically when the utility returns.
6. Improved the complete local UPS shutdown procedure by adding step-by-step instructions to the LCD when a full shutdown is initiated.
7. Added a warning message to the RDU101 web interface showing when the UPS detects a disconnected external battery cabinet. (RDU101 v1.4 required.)
8. Added support for Vertiv's new Power Assist tool.
9. Improved the responsiveness of the status updates reported through the USB HID / Windows OS.
10. Added ability to switch the temperature readings from C to F.
11. Added Italian language to the LCD.
12. Changed the name of the setting [Battery Replacement Time] to [Battery Last Replaced] and updated the default time from 2017-12-14:00:00:00 to the date/time of production.
13. Corrected the issue where "unavailable" was being displayed in the [Battery Temperature] field in the RDU101 web interface.
14. Added legacy GXT4 datapoints to the RDU101 interface: BatteryCharger, BatteryFloatVoltage,  DeviceManufactureDate.  (RDU101 v1.4 required.)
