 Light Color Modes
 -----------------

-color modes for lights. For the most part it mainly fixes issues that have come up with the

+:ghuser:`oxan` has been at it working hard on getting the all of the light code up to scratch and working
+really well with the latest changes to Home Assistant. This is mostly an internal change, but ESPHome has

+
+DSMR
+----
+
+:ghuser:`glmnet` and :ghuser:`zuidwijk` have worked together to bring DSMR support to ESPHome.
+This platform allows you to read your DSMR smart meter via the P1 port. Check out the
+`repo <https://github.com/zuidwijk/dsmr>`_ with more info on the hardware required for this.
+
+
+Thermostat Breaking changes
+---------------------------
+
+:ghuser:`kbx81` Has made a few changes to the :doc:`thermostat</components/climate/thermostat>` climate platform
+in :esphomepr:`2032`, :esphomepr:`2073` and :esphomepr:`2114` to allow for the many different use cases that everyone has.
+Unfortunately this means you might need to make some changes to your YAML configuration to utilize the new code.
+
+ - ``hysteresis`` has been replaced with ``cool_deadband``, ``cool_overrun``, ``heat_deadband`` and ``heat_overrun``.
+ - Climate action timers now govern how quickly climate actions may be called:
+
+   - ``min_idle_time`` is required for all configurations.
+   - ``min_cooling_off_time`` and  ``min_cooling_run_time`` are required where cool_action or dry_action is used.
+   - ``min_heating_off_time`` and ``min_heating_run_time`` are required where heat_action is used.
+   - ``min_fanning_off_time`` and ``min_fanning_run_time`` are required where fan_only_action is used.
+   - ``min_fan_mode_switching_time`` is required where any ``fan_mode`` actions (ex.: ``fan_mode_auto_action``, ``fan_mode_on_action``) are used.
