Mu-editor

=============

* Updated flashing in micro:bit mode so it is more robust and doesn't block
on Windows. Thank you to Carlos Pereira Atencio for issue 350 and the polite
reminder.
* Updated the mu-debug runner so if the required filename for the target isn't
passed into the command, a helpful message is displayed to the user.
* Developer documentation updates.
* Updated to the latest version of uflash, which contains the latest stable
release of MicroPython for the micro:bit. Many thanks to Damien George for
all his continuing hard work on MicroPython for the micro:bit.
* Inclusion of tkinter, turtle, gpiozero, guizero, pigpio, pillow and requests
libraries as built-in modules.
* Update to latest version of Pygame Zero.
* Fix plotter axis label bug which wouldn't display numbers if value was a
float.
* Separate session and settings into two different files. Session includes
user defined changes to configuration whereas settings contains sys-admin-y
configuration.
* Update the CSS for the three themes so they display consistently on all
supported platforms. Thanks to Zander Brown for his efforts on this.
* Move the mode selection to the "Mode" button in the top left of the window.
* Support for different encodings and default to UTF-8 where possible. Many
thanks to Tim Golden for all the hard work on this rather involved fix.
* Consistent end of line support on all platforms. Once again, many thanks to
Tim Golden for his work on this difficult problem.
* Use ``mu-editor`` instead of ``mu`` to launch the editor from the command
line.
* More sanity when dealing with cross platform paths and ensure filetypes are
treated in a case insensitive manner.
* Add support for minification of Python scripts to be flashed onto a micro:bit
thanks to Zander Brown's nudatus module.
* Clean up logging about device discovery (it's much less verbose).
* Drag and drop files onto Mu to open them. Thanks to Zander Brown for this
*really useful* feature.
* The old logs dialog is now an admin dialog which allows users to inspect the
logs, but also make various user defined configuration changes to Mu.
* Plotter now works in Python 3 mode.
* Fix problem in OSX with the ``mount`` command when detecting Circuit Python
boards. Thanks to Frank Morton for finding and fixing this.
* Add data flood avoidance to the plotter.
* OSX automated packaging. Thanks to Russell Keith-Magee and the team at
BeeWare for their invaluable help with this problematic task.
* Refactoring and bug fixing of the visual debugger's user interface. Thank you
to Martin O'Hanlon and Carlos Pereira Atencio for their invaluable bug
reports and testing.
* Various fixes to the way the UI and themes are displayed (crisper icons on
HiDPI displays and various other fixes). Thanks to Steve Stagg for putting
lipstick on the pig. ;-)
* A huge number of minor bug fixes, UI clean-ups and simplifications.

=============

* A new plotter works with CircuitPython and micro:bit modes. If you emit
tuples of numbers via the serial connection (e.g. ``print((1, 2, 3))`` as
three arbitrary values) over time these will be plotted as line graphs.
Many thanks to Limor "ladyada" Fried for contributing code for this feature.
* Major refactoring of how Mu interacts with connected MicroPython based boards
in order to enable the plotter and REPL to work independently.
* Mu has a new mode for Pygame Zero (version 1.1). Thanks to Dan Pope for
Pygame Zero and Rene Dudfield for being Pygame maintainer.
* It's now possible to run mu "python3 -m mu". Thanks to Cefn Hoile for the
contribution.
* Add support for pirkey Adafruit board. Thanks again Adafruit.
* Updated all the dependencies to the latest upstream versions.
* Various minor bug fixes and guards to make Mu more robust (although this will
always be bugs!).

=============

* Add new PythonProcessPanel to better handle interactions with child
Python3 processes. Includes basic command history and command editing.
* Move the old "run" functionality in Python3 mode into a new "Debug" button.
* Create a new "Run" button in Python3 mode that uses the new
PythonProcessPanel.
* Automation of 32bit and 64bit Windows installers (thanks to Thomas Kluyver
for his fantastic pynsist tool).
* Add / revise developer documentation in light of changes above.
* (All the changes mentioned above were supported by the Raspberry Pi
Foundation -- Thank you!)
* Update / add USB PIDs for Adafruit boards (thanks Adafruit for the heads up).
* Minor cosmetic changes.
* Additional test cases.

=============

* Fix to solve problem when restoring CircuitPython session when device is not
connected.
* Fix to solve "data terminal ready" (DTR) problem when CircuitPython expects
DTR to be set (and it isn't by default in Qt).
* Added initial work on developer documentation found here: http://mu.rtfd.io/
* Updates to USB PIDs for Adafruit boards.
* Added functionally equivalent "make.py" for Windows based developers.
* Major refactor of the micro:bit related "files" UI pane: it no longer blocks
the main UI thread.

=============

* Update "save" related behaviour so "save as" pops up when the filename in the tab is double clicked.
* Update the debugger so the process stops at the end of the run.
* Ensure the current working directory for the REPL is set to mu_mode.
* Add additional documentation about Raspberry Pi related API.
* Update micro:bit runtime to lates MicroPython beta.
* Make a start on developer documentation.

=============

* Updated Python 3 REPL to make use of an out of process iPython kernel (to avoid problems with blocking Mu's UI).
* Reverted Save related functionality to prior behaviour.
* The "Save As" dialog for re-naming a file is launched when you click the filename in the tab associated with the code.
