Enhancements
=========
Added support for RTD temperature sensors
When cancelling a print, if cancel.g exists then run it instead of
turning heaters off
Improved file upload speed over the web interface
Chamber heater is now exempted from timeout
Pressure advance now reduces maximum extruder jerk setting by a smaller
amount when the extruder steps/mm is high
The Duet no longer reports itself as an Arduino Due and has its own
Windows driver
Added experimental "maximum average printing acceleration" feature
Try to improve speed of getting file information in Print Monitor
Bug fixes
======
Simulation mode was not working properly
External driver support code sometimes failed to enable the associated
drives
Fixed potential overflow if a user attempted to use non-existent driver
9 on a Duet 0.6
M408 status requests were not handled when in simulation mode
Removed hard coded PATH in project
Changed to CoreNG
Implemented chrishamm's latest Network and Webserver changes, including
Telnet streaming
Added S parameter to M997 command for DuetNG
Increased file read block size to 2K when getting file info
Fixed incorrect parameters for un-retraction moves when z-hop,
orthogonal axis compensation and pressure advance are all enabled
Further refactoring of SD_HSMCI library in preparation for moving hsmci,
dmac and rtc modules into CoreDuet
Merged in chrishamm's changes to Network, PrintMonitor, and his support
for firmware updates from SD card
Fixed print monitor issue that threw out the layer count and time
estimates when there was an initial extruder priming move in the start
gcode
Got rid of most of module SamNonDuePin because CoreDuet now provides the
required functionality
No need to define function watchdogSetup any more because the core no
longer calls it
Switched to the new build system that doesn't need the Eclipse Arduino
plugin and uses the CoreDuet project instead of Arduino to provide
hardware support
