Major changes since v0.10.0:

• Add: Add support for multi-line text (via \n) for #40
• Add: support for STM32 (generic STM32F103) via Arduino_STM32 for #45
• Add: fill param to ElemXCheckboxCreate_P() to support radio buttons & checkboxes with backgrounds other than black. (Breaking API change)
• Fix: mem issue with Flash-based text
• Add: support for foreign characters (UTF-8) in SDL mode for #42

Migration notes:

• Calls to ElemXCheckboxCreate_P() have added two new params (colFill,bFillEn). Existing programs can insert GSLC_COL_BLACK,true immediately before the radio group parameter (nGroup) to match old default.

Major changes since v0.9.2:

• Enhancement: significant memory reduction for Arduino, extensive updates to handle GUI elements in Flash #32
• Modify: streamline user configuration, split Arduino & LINUX
• Add: support for nRF52
• Add: support for m5stack

Migration notes:

• Calls to many APIs may require search & replace for tsElem* to tsElemRef*. Many API calls that didn't previously include tsGui* will now require the addition of the GUI pointer as the first parameter.
• GUIslice_config.h has now been replaced by two separate configurations, depending on the device platform (ie. GUIslice_config_ard.h and GUIslice_config_linux.h). The parameters within these configurations have changed in some cases, so one should update to the new defaults and then customize as required.
• LINUX examples moved from /tests to /linux
