February 2025 (2025-02) — pik-piam/mrremind: Key features delivered, notable changes, and business impact focusing on data model alignment and release governance for the R package.

November 2024 monthly summary: Implemented a high-impact bug fix in remindmodel/remind that corrects the lower bound calculation for industry subsector energy demand in policy scenarios by using the maximum of 2015 and 2020 specific energy demands. The change applies across all regions and subsectors, improving modeling stability and preventing unrealistically low 2015 values. This work enhances policy scenario credibility and supports more reliable planning inputs.
