# Version 2.0.0 - Major Upgrade  - 07 - 2025

The Solution and its scope were simplified. Previous versions of the Solution are no longer supported or maintained.

* **Removed Cold Start from the scope**: “Cold” products are those for which there is little historical sales data.
  * Having 2 model objects in the Solution, for “cold” and “warm” products (as was the case previously) creates complexity in the Flow and in the Dashboards. Defining “cold” adds complexity in the Dataiku Application. 
  * Focusing on time series with 1 year of data or more makes it possible to use the models from Visual Time Series.
  Modeling cold start also makes it more challenging to simplify the solution while retaining good accuracy (the VTS approach may not provide very accurate forecasts when there is little sales history).
* **Replaced Regression model with a Time Series model**:
  * Feature engineering  is now being done implicitly within Time Series Forecasting algorithms, which simplified the Flow.
