1.5.1 (2026-11-09)
This release fixes scripts going missing when Firefox users upgrade from 0.16 to 1.x. External Access can now run background/scheduled scripts and read their logs through sctl, the log page supports copying and exporting, and the @support metadata key is recognized.
🚀 Major New Features
