• sp7 has an important fix for missing prototype generation.
• Standalone shareable Web debugger updated (Experimental)
• GDB debug disconnect forces gdb to exit. Cleaner shutdown.
• Support precompiled=true, link .a/.so files discovered in the library [mcu name] folder.
• Extend check to ignore special case missing prototypes for setup() and loop() where (void) is declared as an argument to the two methods.
• Fix: Resolve new python location for recent changes in the esp8266 package. Visual Micro spiffs (web server data files) upload now supports both older and newer esp tool chain versions.
• Fix: Unabe to create new Arduino projects in Atmel Studio 7. Either failed or caused a hang/lockup of the IDE.
• Insertion of the auto generated missing prototypes (using CTags) is updated to also cater for 1st method in an .ino other than the project_name.ino. This will avoid many compile issues when user types are defined in the .ino code and subsequently used in method sigantures that have missing prototypes. Reminder: CTags are only used for missing prototype generation if "deep search for libraries" (Gcc-E) is enabled. 
• Inserting soft debug breakpoints on 1st line of the setup() or loop() is now supported.
• CLI fixes and new properties
• GDB Hardware Debugging - Programmer/Upload Config updates (check selections after update), OpenOCD Updated to 2020-02-13
• Experimental - Export local web debugger. pre-alpha option to export a self contained portable debugger. Allow a board that is already programmed with visual micro soft debugger break and/or trace points to be connected to another pc that does not have an IDE  (visual studio or visual micro) installed. Applies to software debug only! "vMicro>Debugger>Export Web Debugger". tip: Close the serial terminal after soft debug starts and review the Micro Build output window for usage instructions.

• Fix: Automatic prototype insertion before first method in .ino files (in previous releases the prototypes were inserted before the first code line which required manual insertion of prototypes)
• Fix: Software debugging did not work if the setup() and loop() methods were not in the project_name.ino
• Fix: Software debugging breakpoints were ignored if placed on the first line of a method (on the method name or the line with the methods opening brace)

• Atmel Studio 7 - New menu item "vMicro>General>Automatic Attempt to Set Atmel Studio Project Device". Affects intellisense and which processor/device AS7 believes is being used by the current project. There is no direct correlation from Arduino board names to AS7 therefore switching off this option allows you to be accurate with the selection. (does not affect build/compile). Example: Enables Adafruit Feather M0 to be configured as ATSAM21A18A instead of the default ATSAMD21E18A
