+01.10.2020
+
+Driver Library		:SpiWriteReg, SpiReadReg, SpiWriteBurstReg and SpiReadBurstReg change to public. Allows additional modifications from sketch.
+
+Driver Library		:Setrx no longer has to be set to receive.(internal transmission methods)
+
+Driver Library		:Gdo pins are now set to input / output with set gdo instead of Init.
+
+Driver Library		:Added new sending method. Allows sending without a gdo0 pin.
+
+notes			:The new internal send and receive methods now work completely without an additional gdo pin.
