-- Reverted the default wake delay to 0ms.
+- **BREAKING** Reverted the default wake delay to 0ms.
   - In 92055d377b26fa862c43d1429de1ccbef054af01 this was bumped up to 10ms, which caused problems for several people.
   - The delay can now also be set using the build flag `-D SDI12_WAKE_DELAY=#`

 **To comply with requirements for inclusion in the Arduino IDE, the word Arduino has been removed from the name of this library!**  The repository name is unchanged.
 
-### New Features
+### Changed
 
 - Adds support for Espressif ESP8266 and ESP32
 - Add option of adding a delay before sending a command to allow the sensor to wake.  Take advantage of this by calling the function `sendCommand(command, extraWakeTime)`. This may resolve issues with some Campbell sensors that would not previous communicate with this library.  See <https://www.envirodiy.org/topic/campbell-scientific-cs-215-sdi-12-communication-issues-w-mayfly/#post-14103>
 - Adds Doxygen (Javadoc) style comments to **ALL** members of the library.  The generated documentation is available at <https://envirodiy.github.io/Arduino-SDI-12/>.

-Removed SAMD Tone Conflict
+_Removed SAMD Tone Conflict_
 
-### Improvements
+### Changed
 
 - SAMD boards will no longer have a conflict with the Tone functions in the Arduino core. AVR boards will still conflict. If you need to use Tone and SDI-12 together for some reason on an AVR boards, you must use the "delayBase" branch.
 - Examples were also updated and given platformio.ini files.

 Added processor timer for greater stability
 
-### New Features
+### Added
 
 - Changed the incoming data ISR to use a processor timer, this makes the reception more stable, especially when the ISR is controlled by an external library. This also creates some conflicts with other libraries that use Timer2.
 
-### Improvements
+### Changed
 
 - Made changes to the write functions to use the timer to reduce the amount of time that all system interrupts are off.
 - Forcing all SDI-12 objects to use the same buffer to reduce ram usage.
