- CSV is such a simple format you'd think any implementation would be bug free
... think again ... squashing a number of pesky CSV bugs
- better error reporting

Scenarios!
This update adds functionality to simulate random scenarios with, making fdm ferra data models the ideal business or economic simulation tool. You can now create scenarios and view the scenario outcomes over time or as a distribution for a specific date.
To easily see e.g. the new scenarios functionality, create a new calculation and insert one of the many samples into it. Do this by adding a new project, then inserting a new calculation into it and, while editing the calculation, selecting the samples tool (the one with 'CODE' and a down arrow on it) from the editor assistant view. Then select any of the many samples to insert it and run it to see the sample output.
This update also includes documentation updates and new functions to deal with scenarios and new examples to illustrate the use of scenarios with.
The fdm ferra data models terms of use are now included in the documentation and prominently displayed the first time you use the software. Please read it carefully.
