v60 - AHT20-F temperature sensor support, ACD1200 CO2 sensor support.
      CO2 sensor auto calibration Main device settings parameter support (off, Sensor internal, EAP v1 400 ppm baseline correction, EAP v1 400 ppm baseline correction with drift compensation).
      DI poll period decreased.

0v59 - Add more SPI flash types (now supported: AT25SF321, S25FL132K, S25FL164K, W25Q32, W25Q64, ZD25Q64B). Show SPI flash id bytes in case of unknown flash.

0v58 - Modbus RTU errors shown only if device is addressed.

0v57 - IR2 slider bit fix. RTU slave rx frame length cutting for ignore trailing zeros.

0v56 - HR_text will later work even if assigned UserVar default value was 0. After assigned UserVar change HR_text will be updated on linked HR string change.

0v55 - Removed pressed button view on main screen bottom. Do not accept frames with wrong parity.
       Modbus bus debug info on user settings screen: OK commands counter, fail commands counter, last error description (possible errors: wrong frame format / CRC / function code / reg address / data value).

0v54 - New parameter to permanent configuration: password valid time for access to user variables. ESC press cancel access (user variables locked again).
       3 new HR regs: HR236 - active brightness (100-1%), HR237 - standby brightness (20-0%), HR238 - standby brightness activation time (0.1 sec unit). Change limits for active brightness (100-1% instead of 100-20%).

0v53 - New password window behaviour: window will be hidden in case of wrong password or if no key touch within 3 seconds during password entry.

0v52 - DI are much faster now (for e.g. external buttons used for light).
       Modbus backlight brightness control (HR1, low priority: written value active only until next key press)
       New button function support: On DURING PRESS - HR set only during button active (with extension time, useful for local optical feedback of button press).

0v51 - Add 3 ms delay for SCD30 read to avoid possible I2C block by sensor (workaround from Sensirion).

0v50 - Fix only 19 chars display for HR_Text bug (now 24 chars).

0v49 - Fix SHTC3 zero values bug. Also improved SHTC3 start up check (check sensor ID).

0v48 - Custom CO2 calibration value support.

0v47 - Only HWID2623 (new PCAP): SCD30 CO2 sensor support, RH correction for HTU21, SHTC3 support. Both HWID2623 (new PCAP) and HWID2621 (old PCAP): for 16bit colors, white color will display 255,255,255 instead of 248,252,248.

0v46 - Only HWID2623 (new PCAP): clear screen before loader start. Both HWID2623 (new PCAP) and HWID2621 (old PCAP): HWID can now be readed from firmware bin file (for PC configurator bin files distinguishing).

0v45 - Add modbus mode parameter to settings menu (normal: if baudrate > 19200 -> T3.5 = 1750 us fix value, fast: calculate real T3.5 for all baudrates).

0v44 - Change HR_Text behavior (string selection from REG_H_TEXT_x depends from assigned USER_VAR value, 1..16, 0 -> do not show).
       Support text types: "Number_Percent" and "Color_Number_Percent"

0v43 - After user variable change by linked button/DI, Modbus write to corresponding register will be ignored for 3 seconds (for several Leonis synchronisation while working with PLC, e.g. for dimming one lamp). Above feature works only with last changed user variable (if user will change one variable and after 1 second will change another, first variable will be not ignored for write 2 more seconds as it should be, only second variable will be ignored for full 3 seconds).

0v42 - Fix wrong assigned DI processing (unassigned DI influence to assigned DI bug). Fix password window appear when engineering menu password value = 0 (password protection for user variables active).

0v41 - Check write value to user variable 40 (screen number). Support of user variables password protection. Fix not save values issue for 33-40 user vars in permanent mode.

0v40 - possibility for 2 DI to work like PCAP buttons.

0v39 - support text types TEXT_C_COLOR, TEXT_T_C_COLOR.

0v38 - special color code (0x04) for transparent color. Instead of the darkest green color, it will be transparent. Engineering menu lock (HR0 > 0).

0v37 - default of permanent HR changed to 0; HR permanent/volatile initialized only once

0v36 - fixed problem with access to engineering menu when standby picture is activated. Units for REG_HR_STANDBY_TIME_MS,
       REG_HR_STANDBY_PIC_TIME_MS, REG_HR_STARTUP_PIC_TIME_MS changed from 1ms to 0.1sec
