# Release-0.4.1
* Minor build and documentation changes required to note that we now need to
  pin builds to `nightly-2022-10-22` until Rust-AVR code generation is fixed.

* Storage drivers for composite chips (devices with multiple chips that
  present as multiple I2C addresses)
* Buffered storage driver overlay
* Simple filesystem - SNaFus - that works with our storage drivers.
* Graphics driver and rendering syssystem in new `avrox-display` crate.
* Support for DisplayVisions EA-W096016 OLED display.
* Support for Adafruit 128x128 greyscale OLED display.
* Trivial Bitmap File Format (TBFF) support - see [AVRoxide Utils](https://gitlab.com/snowgoonspub/avrox-utils) for a simple converter app.
* No longer needs a custom built toolchain, `nightly` will do

* TWI (Two-Wire Interface) master driver (both HAL and userland)
* Serial EEPROM driver in the `avrox-storage` crate for the Rohm `BR24T1M-3AM`

* Configurable power-saving with `power_low` and `power_med` feature flags
* Arduino Uno/ATmega328p support started - basic pins, serial support.
* Fix huge bug with TX Complete interrupt eating all the CPU time.
* Workarounds for LLVM interrupt code generation bugs.

* Persist macro works for structs with anonymous fields.
* New serial port flags:  `echo`

* The Persist trait can now be derived for basic structs and enums using the
  derive macro provided by `oxide_macros::Persist` 
* We can now set a stdout device using `avr_oxide::stdout::set_stdout()`,
  and can use print! and println! macros, using the `ufmt` crate :-).
* WallClockTimer now supports scheduling events in the future using the
  `after_delay()` method.
* EEPROM access driver, and also a very basic persistence trait implementation.
* Serial port Read methods now implemented.

# Version 0.1.0
* A stable event handling model I think I'm happy with! :-D
* Bugfixes to the allocator, which is now reliable :-).
* Serial port HAL device now flushes more intelligently.
* Serial port abstract device can now be configured to do things like CRLF
  translation and automatic flush on end-of-line.
* Much nicer event handling model with on_event() callback interface on the
  various device drivers.  (Requires heap memory allocation to work though;
  the old mechanism still works for no-heap use.)
* Implemnentation of a driver for the AVR RTC device.
* We can debounce pin inputs now by wrapping the Pin with a Debouncer

Re-release hopefully with fixed docs generation

# Version 0.0.6
* Use custom build toolchain to work around LLVM bugs
* `[avr_oxide::main]` macro for declaring application entrypoint.
* Added source identities to the Oxide events.
* Codesize improvements, and ability to enable individual drivers with feature
  flags.
* Dynamic memory allocater (enabled with `alloc_` feature flags)

Adds device mocks to support local unit testing, as well as Serial Port abstractions.

Various timer fixes/improvements.

Release 0.0.3, with interrupt/event handling
