 - Now there is  an **IRreceiver** and **IRsender** object like the well known Arduino **Serial** object.
 - Just remove the line `IRrecv IrReceiver(IR_RECEIVE_PIN);` and/or `IRsend IrSender;` in your program, and replace all occurrences of `IRrecv.` or `irrecv.` with `IrReceiver` and replace all `IRsend` or `irsend` with `IrSender`.
 - Since the decoded values are now in `IrReceiver.decodedIRData` and not in `results` any more, remove the line `decode_results results` or similar.
-- Like for the Serial object, call [`IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK);`](https://github.com/Arduino-IRremote/Arduino-IRremote/blob/master/examples/ReceiveDemo/ReceiveDemo.ino#L106)
- or `IrReceiver.begin(IR_RECEIVE_PIN, DISABLE_LED_FEEDBACK);` instead of the `IrReceiver.enableIRIn();` or `irrecv.enableIRIn();` in setup(). For sending, call `IrSender.begin(IR_SEND_PIN, ENABLE_LED_FEEDBACK);` or `IrSender.begin(IR_SEND_PIN, DISABLE_LED_FEEDBACK);` in setup().
+- Like for the Serial object, call [`IrReceiver.begin(IR_RECEIVE_PIN, ENABLE_LED_FEEDBACK)`](https://github.com/Arduino-IRremote/Arduino-IRremote/blob/master/examples/ReceiveDemo/ReceiveDemo.ino#L106)

+For sending, call `IrSender.begin(IR_SEND_PIN, ENABLE_LED_FEEDBACK);` or `IrSender.begin(IR_SEND_PIN, DISABLE_LED_FEEDBACK);` in setup().
 - Old `decode(decode_results *aResults)` function is replaced by simple `decode()`. So if you have a statement `if(irrecv.decode(&results))` replace it with `if (IrReceiver.decode())`.
 - The decoded result is now in in `IrReceiver.decodedIRData` and not in `results` any more, therefore replace any occurrences of `results.value` and `results.decode_type` (and similar) to
  `IrReceiver.decodedIRData.decodedRawData` and `IrReceiver.decodedIRData.protocol`.

 - Changed last uint8_t to uint_fast8_t and uint16_t to unsigned integer.
 - Improved MagiQuest protocol.
 - Improved prints and documentation.
+- Added IrReceiver.restartAfterSend() and inserted it in every send(). Closes #989
 
 ## 3.6.1
 - Switched Bose internal protocol timing for 0 and 1 -> old 1 timing is now 0 and vice versa.
