Changelog:

• Fix installation issue on 32-bit systems
  • Debugging is not supported on 32-bit systems, but that shouldn't prevent MiniCore from being installed

Changelog:

• Add support for dw-link and EDBG based debugWire debuggers. This makes "real" debugging possible using Arduino IDE 2. More info here. Huge thanks to @felias-fogg for making this possible!

Changelog:

• Fix issue where using the bootloader on an ATmega48/P/PA/PB wouldn't work because the selfprogen fuse was't set (#338)
• Fix issue where the allowed sketch size was larger than what was possible

Changelog:

• Update to Urboot v8.0 bootloaders
• Prepare for Avrdude v8.0 boards manager support

Changelog:

• Add 9.216 MHz clock option
• Fix ATmega168 and ATmega88 fuse issue

Changelog:

• Add upload bootloader speed menu option
  • Urboot has automatic baud rate detection, so the upload baud rate can be changed without flashing a new bootloader binary. The Default baud rate option should always work for the selected clock speed. However, faster or slower baud rates may be used if the baud rate error is within about ±2.5%. Use a baud rate calculator to check whenever a clock speed supports a particular baud rate.

Changelog:

• Replace Optiboot with Urboot
• Add bootloader support to ATmega48/A/PA/PA/PB
• Replace Optiboot flash library with one that supports Urboot
• Enable LTO by default
• Add -fpermissive GCC build flag but better compatibility
• Add support for EEPROM uploads directly from the sketch using Urboot or an ISP programmer
  • See README for more information
• Add 6 MHz external oscillator option
• Update toolchain to use Avrdude 7.2

Changelog:

• Fix issue where the AVRISPmkII couldn't be used

Changelog:

• Updates to MCUdude corefiles (Updates currently present in ArduinoCore-avr or certain PRs waiting to be merged)
  • Use ADC instead of combining ADCL and ADCH
  • Improve wiring_shift function
  • Remove unnecessary if branch (because length is checked in while statement below the if-clause)
  • Add bitToggle macro
  • Add parenthesis around 'bitvalue' allowing correct macro expansion
  • Add null pointer check to String destructor
  • Improvements to HardwareSerial.cpp
  • Improve how TXCn bit is cleared in USCRnA register
  • Update abi and new
  • ISO c++ doesn't support binary contants

Changelog:

• Fix the TwoWire destructor to use the array delete operator (ATmega328PB)
• Speed up 'available' function by inserting uint16_t (see arduino/ArduinoCore-avr#433 for details)
• Prevent corruption of disassembler listing command for paths w/ spaces (#235)
• Replace typeof macros like min, max, sq with template-based functions instead
  • Will fall back to the "classic" macros if in a non-c++ environment
• Fix incorrect TWBR register in twi1.c (#244)
• Add Wire timeout
  • Enable Wire timeout by adding -DWIRE_TIMEOUT as a compiler flag, or by uncommenting a line in Wire_timeout.h
• Remove unnecessarytwi_masterBuffer from twi.c (#245)
• Add Xplained Mini as a valid programmer
• Use "correct" lock/unlock byte values in boards.txt
  • Previously Avrdude tried to write 0's to reserved bits that's supposed to be 1's
• Prepare for Avrdude 7.1
  • avrdude.conf updated to fully utilize the features and improvements Avrdude 7.1 brings over the current Avrdude 6.3
