===================== Development Changelog ===================== .. changelog:: :version: v3.5.0 :released: pending .. change:: :tags: postprocessing, bugfix :pullreq: 1467 **Date**: 2025-08-12 Title: Gracefully handle failures in upgrades Description: Failures in upgrades are treated as if the upgrade didn't apply, and we copy baseline results for that building. Previously, if there were failures in any building in any upgrades, we removed those buildings from all upgrades.
