 # 4.3.0
+- Removed default value USE_DEFAULT_FEEDBACK_LED_PIN for last parameter of IRsend::begin(bool aEnableLEDFeedback, uint_fast8_t aFeedbackLEDPin).
+    Therefore IrSender.begin(DISABLE_LED_FEEDBACK) will not longer work!
 - Added convenience function isIRReceiverAttachedForTinyReceiver().
 - Added Extended NEC Protocol macro to TinyIR by Buzzerb.
 - Fixed sendSamsung() / sendSamsungLG() bug.
 - Added functions stopTimer(), restartTimer() and restartTimerWithTicksToAdd().
 - Added rawlen and initialGap to IRData.
 - Added ReceiveAndSendHobToHood example.
-- Removed default value USE_DEFAULT_FEEDBACK_LED_PIN for last parameter of IRsend::begin(bool aEnableLEDFeedback, uint_fast8_t aFeedbackLEDPin).
 
 # 4.2.1
 - Fix wrong type of tEnableLEDFeedback in IRSend.hpp and IRReceive.hpp.
