2012-11-02Added general yield()-hook for cooperative scheduling development (part 2)Cristian Maglie
2012-04-19bugfix for configuring PWM on D6 and D13 too early. (thanks to Limor Fried)Zach Eveland
was starting PWM on these pins too soon - in init() instead of when analogWrite() was called. as a result doing output on port registers directly failed.
2011-12-18fixed digitalWrite on timer 4 pins (D6 and D13)Zach Eveland
2011-12-11fixed TIMER4 use on LeonardoZach Eveland
ATMEGA32U4 has major differences in TIMER4 registers compared to ATMEGA1280 and 2560. turnOffPWM, analogWrite, and initialize routines had wrong registers, bit names, etc.

2009-11-21Improving third-party hardware support:David A. Mellis
- moving back to multple cores per platform - using target instead of platform - moving per-board and per-programmer preferences out of Preferences.java and into a new Target class - adding a new "target" preference - support for platform:value values in board preferences for bootloader path and core - XXX: need to support platform:value syntax for board upload.using preferences.

2009-05-12Optimizing the timer0 overflow handler (for millis()), based on work by ↵David A. Mellis
WestFW and help from mikalhart. Increasing precision of math constants.
2009-03-25Adding support for the Arduino Mega (ATmega1280) to the core and bootloader.David A. Mellis

ATmega328.
2008-11-01Switching tests for __AVR_ATmega168__ to tests for __AVR_ATmega8__ so that ↵David A. Mellis
less changes are needed to support other processors.
2008-07-02Adding ADXL3xx accelerometer example; minor comment changes.David A. Mellis
2008-04-18Fixing millis() overflow: changing millis() and the timer 0 overflow handler ↵David A. Mellis
so that the millis count is updated in the interrupt, and so we don't need to do a conversion inside millis(). Updated to do list.
