-* 5.0.0 switches ONE and OpenAir models (based on ESP32) to the esp-idf framework, freeing up some memory and allowing other advanced features such as bluetooth_proxy and esp32_improv.  If the previous Arduino framework is desired, change the board to `airgradient_esp32-c3_board-arduino.yaml`

 ## Changes
 
-* Added optional package for using LED bar on AirGradient ONE to reflect TVOC values
-* Added examples of Home Assistant automation to disable the display and LED at a scheduled time in configuration.md
+* Added optional substitutions to implement batch-specific PM2.5 corrections using values provided by AirGradient
+  [See details in the packages.md file under the PMS5003 section.](packages.md#sensor_pms5003yaml)
+* Restored logging to default values as it no longer repeats messages about components taking too long to complete
