 >The `activity` and `iob` concepts plotted here are expressed in percentage terms and are used to scale the `treatment.insulin` dosage amounts, so the units for the `activityContrib` and `iobContrib` variables are *units of insulin per minute* and *units of insulin remaining at each minute*, repectively. Because the `activity` and `iob` variables in [oref0/lib/iob/total.js](https://github.com/openaps/oref0/blob/master/lib/iob/total.js) are just the sums of all insulin treatments, they're still in the same units of measurements: *units of insulin per minute* and *units of insulin remaining each minute*.

 # Understanding the New IOB Curves Based on Exponential Activity Curves
 
-As mentioned at the top of this page, the next OpenAPS release will have new activity curves available for users to use. 
+As of 0.6.0 OpenAPS has new activity curves available for users to use. 
 
-In the new release, users will be able to select between using a "bilinear" (looks like what was  plotted above: /\) or "exponential" curves. Unlike the bilinear `activity` curve (which varies only based on `dia` values in a user's pump), the new exponential curves will allow users to specify both the `dia` value to use AND where they believe their `peak` insulin activity occurs.
