-ENVI-met is subject to continuous substantial model development. Simulations run in a version may therefore differ from those run with earlier versions, as is normal for any major release of a physical model. Results from earlier versions remain valid as documented outputs of the model version used. For comparisons between scenarios, we recommend running all variants with the same version.

-  * **Absolute air temperature** is now the primary temperature in result files, listed ahead of potential temperature, and air pressure is referenced to the actual site elevation rather than a fixed standard value. Scripts that read result variables by position need to be updated (see note above).+  * **Absolute air temperature** is now the primary temperature in result files, listed ahead of potential temperature, and air pressure is referenced to the actual site elevation rather than a fixed standard value.

   * **Building indoor climate & air-conditioning heat:** Set an indoor temperature per building and choose whether the heat its air conditioning removes is released into the surrounding air, letting you study the outdoor warming that cooling demand produces. Allow natural ventilation of buildings based on thermal indoor/outdoor thresholds and usage periods.    * **Building indoor climate & air-conditioning heat:** Set an indoor temperature per building and choose whether the heat its air conditioning removes is released into the surrounding air, letting you study the outdoor warming that cooling demand produces.
