Release 1.4.1 (2018-02-20)
==========================

This release is mostly bug-fixes, but a few enhancements have made it in too:

* Added ``curve_left`` and ``curve_right`` parameters to :meth:`Robot.forward`
  and :meth:`Robot.backward`. (`#306`_ and `#619`_)
* Fixed :class:`DistanceSensor` returning incorrect readings after a long
  pause, and added a lock to ensure multiple distance sensors can operate
  simultaneously in a single project. (`#584`_, `#595`_, `#617`_, `#618`_)
* Added support for phase/enable motor drivers with :class:`PhaseEnableMotor`,
  :class:`PhaseEnableRobot`, and descendants, thanks to Ian Harcombe!
  (`#386`_)
* A variety of other minor enhancements, largely thanks to Andrew Scheller!
  (`#479`_, `#489`_, `#491`_, `#492`_)

Release 1.4.0 (2017-07-26)
==========================

* Pin factory is now :ref:`configurable from device constructors
  <changing-pin-factory>` as well as command line. NOTE: this is a backwards
  incompatible change for manual pin construction but it's hoped this is
  (currently) a sufficiently rare use case that this won't affect too many
  people and the benefits of the new system warrant such a change, i.e. the
  ability to use remote pin factories with HAT classes that don't accept pin
  assignations (`#279`_)
* Major work on SPI, primarily to support remote hardware SPI (`#421`_,
  `#459`_, `#465`_, `#468`_, `#575`_)
* Pin reservation now works properly between GPIO and SPI devices (`#459`_,
  `#468`_)
* Lots of work on the documentation: :doc:`source/values chapter
  <source_values>`, better charts, more recipes, :doc:`remote GPIO
  configuration <remote_gpio>`, mock pins, better PDF output (`#484`_, `#469`_,
  `#523`_, `#520`_, `#434`_, `#565`_, `#576`_)
* Support for :class:`StatusZero` and :class:`StatusBoard` HATs (`#558`_)
* Added :program:`pinout` command line tool to provide a simple
  reference to the GPIO layout and information about the associated Pi
  (`#497`_, `#504`_) thanks to Stewart Adcock for the initial work
* :func:`pi_info` made more lenient for new (unknown) Pi models (`#529`_)
* Fixed a variety of packaging issues (`#535`_, `#518`_, `#519`_)
* Improved text in factory fallback warnings (`#572`_)

  simple servo motors (`#248`_)
* Lots of work on supporting easier use of internal and third-party pin
  implementations (`#359`_)

  included but a full fix is in the works (`#385`_)

Not quite as much as we'd hoped to get done this time, but we're rushing to
make a Raspbian freeze. As always, thanks to the community - your suggestions
and PRs have been brilliant and even if we don't take stuff exactly as is, it's
always great to see your ideas. Onto 1.4!

Release 1.2.0 (2016-04-10)
==========================

* Added :class:`Energenie` class for controlling Energenie plugs (`#69`_)
* Added :class:`LineSensor` class for single line-sensors (`#109`_)
* Added :class:`DistanceSensor` class for HC-SR04 ultra-sonic sensors (`#114`_)
* Added :class:`SnowPi` class for the Ryanteck Snow-pi board (`#130`_)
* Added :attr:`~Button.when_held` (and related properties) to :class:`Button`
  (`#115`_)
* Fixed issues with installing GPIO Zero for python 3 on Raspbian Wheezy
  releases (`#140`_)
* Added support for lots of ADC chips (MCP3xxx family) (`#162`_) - many thanks
  to pcopa and lurch!
* Added support for pigpiod as a pin implementation with
  :class:`~gpiozero.pins.pigpio.PiGPIOPin` (`#180`_)
* Many refinements to the base classes mean more consistency in composite
  devices and several bugs squashed (`#164`_, `#175`_, `#182`_, `#189`_,
  `#193`_, `#229`_)
* GPIO Zero is now aware of what sort of Pi it's running on via :func:`pi_info`
  and has a fairly extensive database of Pi information which it uses to
  determine when users request impossible things (like pull-down on a pin with
  a physical pull-up resistor) (`#222`_)
* The source/values system was enhanced to ensure normal usage doesn't stress
  the CPU and lots of utilities were added (`#181`_, `#251`_)

And I'll just add a note of thanks to the many people in the community who
contributed to this release: we've had some great PRs, suggestions, and bug
reports in this version. Of particular note:

* Schelto van Doorn was instrumental in adding support for numerous ADC chips
* Alex Eames generously donated a RasPiO Analog board which was extremely
  useful in developing the software SPI interface (and testing the ADC support)
* Andrew Scheller squashed several dozen bugs (usually a day or so after Dave
  had introduced them ;)

As always, many thanks to the whole community - we look forward to hearing from
you more in 1.3!
