Version 0.3.1

Added

• Support for ATmega8U2 (#77 by @drmorr0).
• Support for AT90USB1286 (#80 by @khimaros).
• Convert static muts into &mut references inside #[entry] and interrupt handlers. This behavior mirrors what cortex-m-rt does (#79 by @tones111).

0.3.0

Added

• Support for ATmega4809 (#63 by @explicite).
• Support for ATtiny841 and ATtiny861 (#67 by @jaxter184).

Changed

• BREAKING: Updated the enumerated values for the SPI clock prescaler field (#64).
• BREAKING: Split the EIMSK register fields into per-bit fields on ATmega328P and ATmega328PB (#74 by @gpgreen).
• Switched to using the svd interrupts command for extracting a list of interrupts instead of parsing generated rust source files for this (#69 by @explicite).

Fixed

• ATmega64: Fixed wrong field size for UMSELn fields in USART peripherals (#64).
• (via atdf2svd v0.2.0): Removed invalid enumerated values from all fields.
• Fixed an error in the 16-bit timer documentation (#67 by @jaxter184).
• Fixed the PRR, PRR0, and PRR1 registers for ATmega328P and ATmega328PB wrongly being read-only (#73, #74 by @gpgreen)

0.2.3

Added

• Support for ATmega644
• Support for ATmega328PB

Changed

• Rewired svd-patching infrastructure to use upstream svdtools instead of the locally vendored script.

Fixed

• Made ADCSRA for ATtiny84 read-write.
• Made TIFR registers for ATmega timers read-write.

0.2.2

Added

• Support for ATmega168
• Support for ATmega48P
• Support for ATtiny84

Changed

• #[entry] causes a (readable) compile-error when attempting to build for non-AVR targets.
• PINx registers are now writeable, which enables efficient toggling of bits in the corresponding PORTx register.

Fixed

• inline-assembly is now only emitted when building for AVR targets to prevent weird compiler errors where AVR instructions are emitted on e.g. x86_64.
• Fixed an issue in the build-system in preparation for the next svd2rust release.

0.2.1

Fixed

• Fixed interrupt::free() not working as advertised, because a wrong address was read.

0.2.0

Added

• Support for ATtiny88.
• An asm module with wrapper functions for various assembly instructions.

Changed

• Various patches for ATtiny85, fixing up a lot of the remaining inconsistencies.
• interrupt::enable() is now unsafe, as it would otherwise be possible to enable interrupts safely inside a critical section.
