MRC88 Firmware v2.22
• Fixed a problem with macros under the Vol+ and Vol- keypad buttons not being executed when using the MRCREM remote (instead, the MRC88s volume would ramp as if there was no macro under the button).
• Added support for accessing the Vol+ and Vol- keypad button macros using the RS232 "Digital" interface protocol. Specifically, the "Execute Keypad Button" command (!{z#}MK{k#}X{i#}+) now accepts a 1 (Vol+) and a 2 (Vol-) for the keypad button parameter.
• RS232 output commands in macros will now be repeated when the button is held down (in a similar fashion to how an IR command will be repeated). The repeat rate for RS232 strings is 4 times per seconds (every 250ms). This now makes the MRC88 behave the same as the latest XTR39 and SPLCD firmware.

MRC88 Firmware v2.11
• Added support for the iPort^TM.
• Added support for only using output 1 of the Xantech Dual-Tuner.
• Added support for the XMusic Server.
• Now supports the XDT and XMS on router ports.
• Will now process all RC68+ codes when the zone is off.

MRC88 Firmware v2.09
• Added support for XIR2-type IR. This is the IR type created when learning on the SPLCD and XTR39.
• Boosted the Zone Audio Inputs by 6.25 dB, to better match the normal audio inputs.
• When the pre-amp outputs are set to be fixed, attenuated them by 7.5 dB to more closely match the original input signal.
• Added support for source button presets.
• When using a sense input to trigger a page, the system will now run any macro associated with that sense input in addition to triggering the page.
• Removed the volume ramping logic when paging. This provides a massive speed-up in effective paging response time.
• Now supports macros under the keypad VOL+ and VOL- buttons.
• Added support for the MRC88 remote.
• Now handles faster RS232 input better.

MRC44 Firmware v3.13
• Eliminated unintentional system muting when using pulse IR codes.

MRC44 Firmware v3.12
• Improved management of Control Outs so that, in Expanded Mode, the Control Out on the Primary Controller/Amplifier will be ON if any zone in the system is on, otherwise it is OFF. The Control Out of the Secondary Controller/Amplifier will always be OFF.
• Improved operation of the ALL OFF controller/amplifier command so that in all modes (including expanded mode), source devices maintain correct power state.
• Removed support for the ZONE SET CONTROL STATUS controller/amplifier command.

• Upon startup, the firmware will now automatically run the macro associated with RS232 trigger macro #127 (if it exists).
• Made some modifications to the generation of XIR2-type IR in order to better support multiple button presses (such as when user attempts to enter a channel number via a numeric keypad).
• Numerous changes to support newer Compact Flash memory cards in the 6.4 units that were previously causing display anomalies.
• Improved the font rendering. Text drawn by the unit now has better spacing between characters.
• Fixed an issue with communicating with the original Compact Flash card on very old 6.4's that was introduced in version 2.01.
• Cleaned up the ellipsis handling on text boxes with strings that are too long to fit in the box.
• Fixed a bug in the text boxes that are less than one line of text tall. The bug only shows up when attempting to display text that is longer than will fit in the box.

SPLCD Firmware v1.70
• When a text box is not tall enough for a single line of text, the SPLCD now will draw the text vertically clipped to the box boundaries. Previously in this situation nothing would show up at all in the box.

SPLCD Firmware v1.69
• Added support for the next generation video chip, as current version has been discontinued.

SPLCD Firmware v1.65
• Fixed some issues with XIR-2 IR that would cause the buttons to sometimes be sluggish, and also possibly cause the IR code to fail to control the device.

SPLCD Firmware v1.62
• Fixed issue with XIR-2 (IR Library) IR generation.

SPLCD Firmware v1.59
• Fixed a problem with the colors of the password page on 3.9 and 5.7

• Fixed a problem where some XIR2-learned codes would run too long.
• Fixed some text formatting issues in the MRC88 Information box.

• Now all text boxes and bar objects support different color values for the box outline versus the text/bar itself. Use of this feature requires support in Dragon.

SPLCD Firmware v1.53
• Fixed problem that occurs when changing a Data Dictionary memory location from a Text Value to a Data Value
• Now when starting up if the system detects a possible problem with the project it will ask the user if they want to abort loading the project, otherwise it will go ahead and load it. This is designed to address the situation where an installed system will appear to lose the project when the power goes out.

• Added a new Dragon command that will erase the existing project from the device and reset all the options to the defaults.

• Fixed a problem with RS232 Queries that was introduced in version 1.50. All queries except the new dynamic data queries were returning ERROR

SPLCD Firmware v1.52
• Fixed a display problem in the 6.4's that under certain circumstances would cause the currently selected source button to not display correctly (you could see both the up and down state of the source button at the same time).
• Fixed a problem in the bar display code that would cause the SPLCD to lock up if the minimum and maximum values were not set correctly in Dragon.
• Added support for the MRC88 keypad query "keypad type". This allows the MRC88 to correctly report the SPLCD firmware version to Dragon, when the SPLCD is used as a MRC88 keypad.
• Added support for a "Go to Home Page" navigation button
• Fixed problem with the "Backlight OFF" internal command that was causing the backlight to go off then immediately back on. (Tech Support ISSUE ID: 32305)

XTR39 Firmware v1.36
IMPORTANT NOTE: The RF2IR support in this firmware will only work with RF2IR firmware version 1.13 and higher. Attempting to use it with older firmware versions of the RF2IR will cause the RF2IR to incorrectly.
Massive changes to the rotary wheel button code to address issues found during new manufacturing QA/Usage testing. These buttons should now be more reliable and responsive. This should be most noticeable when waking the unit from sleep mode by touching the wheel itself.
Fixed some issues with RF-based commands. They should now be more consistent.
Fixed some issues with the touch panel buttons. It should be easier now to perform multiple button presses, such as entering in a 3-digit channel number.
• Touch Buttons will now stay in the depressed state while the system is busy executing the macro under the button. This should help improve the overall user experience.

XTR39 Firmware v1.35
IMPORTANT NOTE: The RF2IR support in this firmware will only work with RF2IR firmware version 1.13 and higher. Attempting to use it with older firmware versions of the RF2IR will cause the RF2IR to behave incorrectly!
• Fixed a problem with learning IR, where sometimes it would cause Dragon to lock up.

XTR39 Firmware v1.28
• RS232 repeats enabled. Will repeat the string approximately 4 times a second.

XTR39 Firmware v1.19
• Added write-protection for the boot loader. This will keep the unit from losing the boot loader when a bad Dragon transfer occurs. (Prevents unit from locking up when an incorrect firmware is loaded to the XTR39.)
