• V3.00 Maxduino OTLA as reference name for this version. Check https://github.com/rcmolina/otla_tzx for some testing.

• V2.03 OTLA working with tzx id15 My own otla of HoH at 12600 bauds (29s) vs old turbo at 5800 bauds with z802tzx using compression zx7b (62s). About half of time as expected: https://github.com/rcmolina/otla_tzx/blob/main/hoh8_zx.zip https://github.com/rcmolina/z802tzx3/blob/master/HoH8%5B5800%5D.tzx

• V2.02 Oled driver optimizations.

• V2.01 aka "San Fermin". Fixed oled corruption and new cartoon8x16 font.

• V2.00.x New maxduino stable and tested reference version.

• V1.77.x SEE VERSION.H FOR MORE DETAILS first rolling version with automatic version numbering. See git commit history for changes: https://github.com/rcmolina/MaxDuino/commits/master See version.h (and the Menu "Version..." option) to display what version you currently have. V1.77 uses semantic versioning : MAJOR.minor.patch.sha (build is incremented for each commit, and sha corresponds to the first few characters of the github commit hash) e.g. 1.77.1234.ffca means this is v1.77 , patch number 1234 (based on number of changes), commit HEAD ffca

• "New MaxDuino": No version Numbers due to collaborative new contributions for the project 26/06/2022 Oric: Fixed pointer bug when loading some tap programs (Pulsoid, @desUBIKado). 24/06/2022 Assisted Oric tap multiblock loading with automatic pausing when setting Skip_BLK2A flag to off in menu. 18/06/2022 SAMD21 Support (@David), tested Arduino Micro and new pin definitions (@Rafa) 14/06/2022 SdFat much improved, now userconfig7.h with all options activated, and also until 10 subdirs and max filelength 256. David is your hero! 11/06/2022: ZX:inject the real filename into the fake ay header + Refixed inversion for zx polarity loading. zx81:Removed initial pause from zx81 loading to avoid inversion problems.

• V1.76 New option to trace ID15 blocks #BLOCKID15_IN. Support variable baudrate on the fly for Amstrad CPC ID11 blocks (like TSXControl). A bunch of bugs solved: At last solved memory corruption problem when reconfiguring options due to wrong buffer overflow , also reoptimized size to free more space. Changed also logic for searching extension when reading file (thanks to David Hooper alias stripwax). Double font i2c_start syntax error (@alferboy).

• V1.75 New option to handle more than 255 block in Blockmode if needed. Decrease block count in Blockmode to skip some blocks thus matching live oled block count.

• V1.67 End of file adjustments, better loading in Camputerx Lynx tzx id15. Removed Oric final pause, for testing, forgot to remove it. Some changes in STM32 for handling the clock.

• V1.66 aka "Beast Nano". New userconfig option for optional oled on screen print, so more space for nano to include oric and uef in the same upgrade. Fixed bug when dragon to msx switching without reset.

• V1.65 Code rearrangement for esasier pinout modification. Support for the new Maple miniduino (STM32) from Antonio Villena.

• V1.64 Thinary PCB support (cheap arduino nano every). Many thanks to Ricky El-Qasem for his help and his perseverance for this to work !!

• V1.63 New Logos. Fixed side-effect on MSX cas when implementing Oric native tap files loading.

• V1.62 aka "Marble". New StandardFont (8x8) pack. DoubleFont (8x16) support. Improved speed loading in oled marble mode (XY2force) @alferboy. MenuBLK2A option in userconfig, no dependencies from UEF (@merlinkv).

• V1.61 Graphic 128x64 and text 128x32 combined mode for Oled screens. Optional 8x8 bold font. Better XY2 thanks to @alferboy.

It's posible to select RECORD_EEPROM and LOAD_EEPROM both for better testing when selecting new logos in userconfig.h, pressing MENU simulates a reset to show logo again.

• V1.43 aka "Mar Menor". Implemented half-interval (logarithmic) search for dirs and block selection. Now ROOT button used as pivot. Menu functions now activated with ROOT + STOP, new half-interval search with ROOT + UP/DOWN.
