v1.45
==================================================
- Presets: Battery Type is now saved and recalled with presets.
- RF Menu: Renamed "SEND" button to "SAVE\nSEND" to clarify functionality.

v1.44
==================================================
- Minor UI tweaks.
- Added missing TC voltage to presets.

v1.43
==================================================
- Configuration Presets:
  * Added system preset management accessible from Settings -> PRESETS.
  * Save and recall up to 3 complete configurations including all transmitter settings (frequencies, names, encryption), RF power level, group code, ZaxNet frequency, and timecode settings.
  * Customizable preset names.
  * Confirmation warning popups when saving or loading presets to prevent accidental overwrites or unexpected setting changes.

v1.42
==================================================
- Low Battery Warning:
  * Adjusted critical low-battery overlay opacity to for improved background visibility while warning is active.

v1.41
==================================================
- Battery Calibration USB Safety Interlock:
  * Disables battery calibration adjustments and displays an on-screen warning when the unit is powered via USB, preventing inaccurate ADC voltage calibration from USB power rail variation.

- Battery Chemistry & Gauging Improvements:
  * Updated 2xAA Lithium Primary discharge curve based on empirical battery rundown test data for more accurate capacity readings.
  * Changing battery type in settings now immediately updates system battery chemistry.

- Various performance and stability improvements.

v1.40
==================================================
- Battery Gauge & Monitoring Improvements:
  * Added boundary hysteresis to the battery status icon and color to eliminate flickering near level transitions.
  * Updated 2xAA alkaline discharge curve based on empirical battery rundown data for improved capacity estimation.
  * Lowered critical battery warning threshold to 5% to avoid premature warnings while maintaining safe shutdown margin.

- Various performance and stability improvements.

v1.39
==================================================
- Serial Number Display:
  * The Firmware screen now displays the hardware serial number above the firmware version when configured.

- Various Performance and usability fixes.

v1.38
==================================================
- Transmitter Power Screen Global Wake Handling:
  * Selecting GLOBAL WAKE mode now automatically locks the target ID to global ("ALL" / ID 0) and disables the ID +/- buttons.
  * Entering the Power screen while GLOBAL WAKE is active automatically defaults the target unit ID to "ALL" (ID 0).
  * Issuing a Global Wake command overrides and resets individual power mode states in the transmitters themselves, clearing individual power modes so all units follow the global mode going forward.

v1.37
==================================================
- Performance & Stability Enhancements:
  * Enhanced internal task synchronization and memory access for improved system stability and responsiveness.
  * Optimized background communication routines and data handling efficiency.

v1.36
==================================================
- Timecode Transmission Safety & Control Locks:
  * Added a confirmation warning dialog when disabling Timecode TX, notifying that transport control and global power mode commands will also be disabled.
  * Main menu REC/STOP transport button is disabled and grayed out when Timecode TX is disabled.
  * Global ("ALL" / ID 0) power mode selection is locked out in the Power screen when Timecode TX is disabled, defaulting to individual transmitter IDs.

- Confirmation Dialog Navigation:
  * Pressing the hardware ENTER key now confirms active popup confirmation dialogs.

v1.35
==================================================
- Confirmation Popup UI Styling:
  * Updated confirmation popup button text to "PRESS [OK] KEY".
  * Updated button styling to a black background with white text to look like an instruction label instead of a button.

v1.34
==================================================
- Dim Settings UI Redesign:
  * Added dedicated +/- buttons for Dim Level and Dim Delay, allowing direct adjustments without toggling between fields.
  * Added button hold auto-repeat for fast value adjustments.
  * Capped maximum auto-dim delay to 250 seconds.
  * Improved layout and label alignment on the Dim Settings screen.

- Transport & Audio Menu Updates:
  * Standardized Transport screen button indicator colors (Record highlighted in Red, Stop in Green).
  * Renamed "AUDIO GAIN" button and screen title to "TX AUDIO GAIN" for consistency across transmitter menus.
