Release 0.12

- fix reading firmware name
- fix typo in keyword argument `accept_unknown_hardware`
- use product id read from device instead of hardcoded one, this fixes connecting to unknown hardware
- fix I2C_rdwr transfers using SMBus

0.11

Release 0.11:

- removed unsupported commands for memBlock hardware
- fix setting receive timeout on Linux and Windows, be aware on Linux access to the USB device as non-root user needs to be configured using udev rules
- exclude macOS system serial ports by default, this fixes a huge slow-down on macOS using ECUManager
- added type hints
- this library now requires Python 3.8 or above

0.10

Release 0.10:

- fixed SMBus.i2c_rdwr not transmitting data correctly
- handle USB exceptions when device becomes unavailable
- hardware: added new microcontroller variant for memBlock ECUs
- added flag to allow connecting to unknown hardware IDs with default set of available commands

0.9

Release 0.9: faster communication over USB

- Configurable communication delay when transmitting responses over USB, defaults to 75 µs. This was previously 2
ms (default value of hardware), now communication takes 2 ms less time
- Added libusb_package dependency, required for configuring the communication delay
- ECUManager now skips already open serial ports by default, this allows several instances of the ECUManager to be
used across different Python programs at the same time
- ECUManager now supports excluding serial ports from being scanned
- Fixed `calibration_to_file` not saving calibration values
- Fixed typo in `enabled_all` method
- Report UUID and product ID of unidentifiable ECU hardware
- Added DIGITALINPUT command
- Only reset serial port read buffer when communication fails, this speeds up communication
- Started implementing CP2102N (USB-Serial chip used in ECUs) with pyusb without requiring the proprietary SiLabs
VCP driver
- Added MIT license information to source files

0.8

Release 0.8: better I2C controller support

* fix detecting hardware in bootloader mode
* added 30ms delay between command retries to allow ECU firmware to detect timeout
* added i2c_get_smbus method that returns an SMBus-like object for transparent I2C communication with ECU in controller mode
* added i2c_speed attribute to configure I2C clock speed for ECU in controller mode
* added command write and response read times to debug logging

0.7

Release 0.7: minor bug fix

0.6

Release 0.6: faster connecting to new device and support for custom hardware and commands

* added product_id property to help identify hardware variants
* I2C: fix communication when using smbus2 library
* doc: overview of hardware variants
* new hardware variants: ECU-PCON-mp6single, ECU-PCON-mp6quad, ECU-PCON-ABP2LAN and ECU-PCON-SLF3
* improved connecting to new device, this speeds up the process significantly
* added `send_raw_command` to allow sending custom commands and parsing the response
* `channel_info`: it now also return high and low side output voltages
* serial: clear buffers before sending command
* refactored parsing response data
* refactored definition of hardware variants

0.5

Release 0.5: documentation, new hardware support and ECUManager improvements

* doc: added Getting Started guide
* doc: documented serial protocol
* new memBlock hardware revision 1.1
* new ECU-PCON-mp6quad hardware
* added I2CCONTROLLER command
* ECU: made short form of UUID (8 characters) the default
* ECU: added attribute 'serial_port'
* ECUManger: .get_by_uuid() now uses the short form (8 characters)
* ECUManager: sort found ECUs by their UUID

0.4

Release 0.4: Added ECU-P8 rev. 1.1

* fixed push button configuration command
* catch all serial exceptions in ECUManager
* new ECU-P8 hardware revision
* added reading analog inputs from ECU-P8

0.3

Release 0.3: Added ECU-P2 hardware variant to library.

0.2

Release 0.2

- Fixed communication with CP2102N when using newer Windows drivers
- Apply custom timeout when initially connecting to the ECU-P (not only when sending commands from the user)
- Improved error message when communication with ECU-P fails

0.1
