A new model version, GHGenius 5.0a, is available to fix two bugs that have cropped up.
About versioning. Going forward we intend to keep our version numbers more meaningful than in the past. Lettered versions of the model such as 5.0a are intended to be strictly bug fix releases that do not add any new data or pathways. They will be used for bug fixes with macros, labels, or small fixes to pathways.
If any bug fixes are far reaching or impacting default pathway settings they will be pushed to a decimal incremented release such as 5.0.1 or 5.0.2. Our plan is to have lettered versions almost entirely cross compatible, and decimal versions with small updates. Larger, probably annual, updates will be labelled as 5.1.0 or 5.2.0.
