KPI Analyzer: The KPI hierarchy models now support changing hierarchy equations over time. This is necessary to handle M&A
situations at companies, or changes in segment reporting. Currently, hierarchies remain curated internally by Exabel.
KPI Analyzer: New spread model type. This is analogous to the ratio model, but instead of modeling the ratio between the KPI and
the data, we model the difference (spread) between the KPI and the data. For more information, see the
documentation.
