 There are modules that can be soldered or stacked to the display that offers an I2C interface for communication instead of the 8+ digital lines that are used to send data to the display.
 
-Most of these modules use the wiring that is supported by this library's default configuration. If you use a module with a different wiring, you can use one of the class constructors which allow you to specify the pin assignments.

+## Changes Version 2.0.0 (2022-05-26)
+
+* The interface was modified to use 8-bit datatypes as supported by the underling hardware.
+* A createChar version with PROGMEM character data for AVR processors was added.
+* A constructor with pin assignments was added to allow easy adoption to other wirings than the default.
+
+Thanks to additions from @markisch.
