+-------------------------------
+Preview of the Upcoming MESSAGEix-Materials Release
+
+This upcoming release of MESSAGEix-Materials introduces significant enhancements to the current model.
+It features improved calibration and updated parameterization, drawing on the latest statistics and findings from recent literature.
+Most of these updates reflect developments made during the ScenarioMIP project.

+- Trade representation for alumina has been implemented
+- The aluminum has been fixed in 2025 independent of SSP setting
+- The 2020 aluminum demand was slightly revised in some regions
+- The energy intensity of alumina refining was revised and differentiated by region based on IAI data
+- The fuel use for alumina refining in 2020 was calibrated based on IAI data
+- The energy intensity of aluminum smelting was revised and differentiated by region based on IAI data
+- The historical smelting capacity was calibrated based on an accurate global capacity data set
+- The historical smelting and refining activity in 2020 was calibrated based on BGS statistics
+- The maximum recyclable aluminum scrap ratio is now differentiated by SSP
+- The heat requirement and cost for aluminum scrap preparation is now differentiated by SSP
