Release notes for MUSE v1.3.3 (February 7, 2025)

These are the main changes in MUSE v1.3.3.

Bug fixes

Fixed an error with the LCOE and EAC outputs (#657)

• Data in these outputs was previously shown for the wrong year (e.g. LCOE values for 2025 shown as 2020). This is now fixed.

Fixed errors in the calculation of commodity supply (#585)

• Particularly in relation to multi-region models, and technologies with multiple end-use commodities

Deprecated features

Dropped the foresight and forecast parameters (#641 and #645)

These parameters previously allowed agents to forecast beyond the investment year, but this feature has been dropped since v1.3.0. Users are advised to remove these parameters from their settings files, otherwise a warning will be raised.

Optimization

Several changes aimed at improving performance and simplifying the codebase for ease of maintenance. See #647, #641, #650, #642, #645. Some of these changes may also have a subtle effect on results.
