0.13.0

Features and enhancements

• Switch patch board layout from slots to a slot/grid hybrid.
• Add nodes quick search. Hit Edit → Insert Node, or Double click the patch
  board, or press I key to invoke it.
• Add the Helpbar. The new pane that shows contextual help for a node. Hit View → Toggle Helpbar or press H key to show it.
• Implemented panning of the patch board. Now you can navigate large patches by pressing spacebar or middle mouse button and drag.
• The terminal nodes now have their own outstanding look (circles) so that you can quickly scan a patch to find its inputs and outputs.
• Now you can set starting values for flip-flop, count, and many other simply binding a desired initial value to their outputs.
• Add few missing tooltips for UI controls in the Inspector and Project Browser.
• Browser-based IDE now shows the direct download link for the desktop IDE when trying to upload.
• The Help main menu item now goes last in the desktop IDE as it should be.

Bug fixes

• Fix upload on boards with multiple controller variants. Notably, Arduino Nano which has ATmega328 and ATmega168 versions.
• xod/core/count node now works fine with a fractional STEP’s.
• Fix compilation error saying “dtostrf is not defined” which occurred on non-AVR platforms when trying to cast a number to a string.
• Avoid false xod/common-hardware/button triggering on boot.
• Tweak buttons overlapping long node label for a selected item in the Project Browser.
• Double click on the add (+) button in the Project Browser no longer drops you to the clicked node implementation. You can still drill down if you’d click the label outside of a button.

Optimizations

• Move most of the static data in generated C++ to flash memory section. It lowers RAM consumption at the order of 2× to 3×.
• Get rid of a separate topology mapping in C++. Now all node IDs are already sorted topologically. It saves one or two bytes of RAM and Flash per native node.
• Provide API for native nodes to access values stored in their outputs directly. It saves RAM for the nodes which keep their internal state, e.g. flip-flop, count, fade, etc.

Deprecations and removals

• Rudimental support for JS-based platforms is dropped so that we can focus on C++ microcontroller platforms and support them well.
