and this project adheres to [Semantic Versioning](https://semver.org/spec/v2.0.0.html).

## [0.9.1] - 2021-08-10
### Fixed
- Call `close()` on Drop, allowing recovery from failures in `init()`.

## [0.9.0] - 2021-07-01
### Changed
- Updated the `libftd2xx` dependency from 0.29.0 to 0.31.0.

## [0.8.0] - 2021-05-29
### Changed
- Updated the `libftd2xx` dependency from 0.28.0 to 0.29.0.

## [0.7.0] - 2021-04-18
### Added
- Added checks for missing ACKs from the I2C slave.
  Missing ACKs will now return an `NakError` from the I2C traits.

### Changed
- Changed the default implementation of I2C traits to wait for a slave ACK
  before transmitting more bytes.  The previous behavior can be retained by
  calling `set_fast(true)`.

## [0.6.0] - 2021-04-10
### Added
- Added support for the FT4232H.
- Added support for the FT2232H.

### Changed
- Changed the default linking method on Linux to dynamic.
  Static linking can be enabled with the `static` feature flag.
- Changed the I2C pins to input (tri-state) when in idle mode.

### Fixed
- Fixed AD0 (SCL) pulling low when when I2C is first initialized.
- Fixed I2C AD0 & AD1 (SCL & SDA out) being pulled low when another OutputPin
  changed state.

## [0.5.1] - 2021-03-20
### Fixed
- Fixed the I2C `Read` trait not setting the read address bit.
- Fixed the I2C `Write` trait not driving SDA as an output when clocking data
  out.

## [0.5.0] - 2021-03-20
### Added
- Added checks for pin allocation, trying to take output pins 0-2 while using
  the SPI interface will now result in panic.
- Added I2C traits.
- Added `Debug` for interface structures.
- Added `with_serial_number` and `with_description` constructors.

### Changed
- Changed the FTDI MPSSE initialization to occur once globally for the device
  instead of inside the SPI device trait.
- Changed the `Delay` structure to contain dummy data for possible future use.
- Change the `Ft232hHal::with_ft` to `impl From<Ft232h> for Ft232hHal`.

### Removed
- Removed `Eq` and `PartialEq` traits on the `Delay` structure.

## [0.4.0] - 2021-03-05
### Added
- Added a `Delay` structure that implements the embedded-hal delay traits.

### Changed
- Updated `libftd2xx` dependency from 0.24.0 to 0.25.0.
  This updates the vendor library from 1.4.8 to 1.4.22 for Linux targets.
  This should fix timeout conditions that previously occurred when rapidly
  toggling GPIO pins.

## [0.3.0] - 2021-02-14
### Changed
- Improved latency for GPIOs

### Fixed
- Fixed the example code for `Ft232hHal::new`.
- Fixed pins 5, 6, 7 not being usable as outputs.

## [0.2.0] - 2020-09-13
### Added
- Added SPI non-blocking traits.

### Changed
- Updated to libftd2xx 0.17.0
- Updated to embedded-hal 0.2.4

## [0.1.0] - 2020-09-12
- Initial release
