8.0.0 (2026-08-18)

⚠ BREAKING CHANGES

• The APIs deprecated during 7.x are removed. startDfu takes androidParameters, darwinParameters and dfuEventHandler instead of the special parameter classes and individual callbacks, and DfuEventHandler.onFirmwareUploading is replaced by onDfuProcessStarted. See the "Migrating to 8.0.0" section of the README.
• resolve assets on macOS and report firmware file errors accurately (#296)
• android: Android apps must declare BLUETOOTH_SCAN and, if they scan on API 30 and below, ACCESS_FINE_LOCATION themselves. Apps relying on the plugin's declarations will stop receiving scan results until they do. See the "Android permissions" section of the README.
