21.1.0_ETA_function_def
- ∙ The processing of large function files, such as wind records, has been made more efficient for speed and storage.
- ∙ Functions can be added or modified after the analysis is run and the model is locked.
- ∙ More control has been given to locating function files on the local computer or network.
