Changelog

Engine releases.

Engine releases follow the grid-sim repository. Corrections to published investigations are tracked separately and publicly under the Errata policy — a superseded post is banner-flagged, never silently edited.

First public release.

• Coupled energy-adequacy (half-hourly dispatch, 1985–2024 weather) and system-stability (swing-equation) engines.
