v1.51 Release Notes

Release Date: 9/16/2017

Improvements

• Interface Builder now has a "Calculator" project type. This is for single page simulations and works with models written in Python/R/SimLang.

• The file manager can now rename files.

• The property reportPer is now used in model context/config files for Vensim as a means to limit the data points displayed in graphs. Formerly there were two properties reportPer and savePer with slightly different meanings. Use this when models have time series with thousands of data points. Specifying a reportPer in the model config file will make graphs load faster.

• The model context format was changed to remove an extra level of nesting. The old format for specifying the save property on a variable was:

{
    "variables": {
        "Price": {
            "simulation": {
                "save": true
            }
        }
}

The new format is:

{
    "variables": {
        "Price": {
            "save": true
        }
}

• The list of groups can now be navigated page by page. This was released as part of Epicenter v1.50.10 on 8/26/17.

• Forio Epicenter now supports NodeJs version 6.10. This can be selected in the Project Settings / Node page. This was released as part of Epicenter v1.50.10 on 8/26/17.

• Group expiration dates and run limits can now longer be edited with individual users. While they are still enforced at the user level, the limits are only entered at the group level. This was released as part of Epicenter v1.50.10 on 8/26/17.

Bug Fixes

• Uploading a file by dragging and dropping to the file manager would often successfully upload the file but still display an error "upload failed".

• Interfaces can now acess variables with capitalization Step and Time as well as the previously existing names STEP and TIME in Vensim simulations.

• Variables from STELLA within submodels could not always be accessed from a simulation interface.

• Team end users were not able to be deleted due to a missing button. This has been fixed and was released as Epicenter v1.50.10 on 8/26/17.

• Team members can now edit the user first/last name even when the username is an email address. This has been fixed and was released as Epicenter v1.50.10 on 8/26/17.

• Sorting the group list by "Last Login" would give an error. This has been fixed and was released as Epicenter v1.50.10 on 8/26/17.

• Other updates for performance and stability, particularly with regard to the Interface Builder, User APIs, Multiplayer APIs, and SFTP capability.
