    In the newest LEAP version 2024.2.0.0 it appears that Growth functions are no longer allowed within a time series (interp) is there a reason for this, or has anyone else tried this? A working Area now needs several modifications due to the change.

    That's right Robert. I assume you mean something like this?

    Interp(2013, Growth(-1.5%), 2018, Growth(-1%), 2030, Growth(0.2%))


    I decided to disallow this. In some cases, it was anyway causing circularity errors, but in looking at that issue I further realized it should not be allowed since growth works by looking at the value in a previous year, and previous year values can only be worked out if the Interpolated values are already sorted out (which in itself requires the results of the growth function).

    In general, if you want to have multiple growth rates you can do something like this:

    Growth(a%, 2020, b%, 2030, c%)

    Apologies for not including this in the What's new change log.
