+### New features
+
+#### mikroSDK
+
+Added following macro patterns:
+
++ `GPIO_Pxy`
+  + Replaces `Pxy`
++ `GPIO_PIN_x`
+  + Replaces `PIN_xy`
++ `GPIO_PORT_x`
+  + Replaces `PORT_xy`
+
+All use of the old macros has been changed by new ones. This affects all board and mcu packages as well.
+
+> Note that old macros shall be left in the SDK for a couple of upcoming versions, giving users time to make adequate changes to any code they might have.
+
+#### CORE
+
+All `mcu.h` header file for XC8 supported MCUs have the following change applied:
+
++ Changed all occurrences of `Pxy` to `_Pxy`
+  + Where `x` i a letter from A to Z and `y` is a number from 0 to 9
+
+> Note that these changes shall be reverted once the old pin definitions are removed from the SDK.
+
 ### NEW HARDWARE
