 /** Changelog:
+ * 2023-10-03 tonhuisman: Optimizate alignment of settings struct, exclude some logging if BUILD_NO_DEBUG is defined
  * 2023-02-27 tonhuisman: Implement support for getting config values, see AdafruitGFX_Helper.h changelog for details
  * 2022-07-30 tonhuisman: Add commands to set scroll-options (settext, setscroll, setstep, setspeed, setempty, setright)
  *                        Fix issue that on startup the display wasn't cleared (unit reset should turn off the display)
