Change Log

2.2.0 (2018-03-28)

2.1.1 (2018-03-22)

• Updated external Scandit Engine library to version 5.7.
• Fixed incorrect domain name detection and verification in some particular local testing environments.

2.1.0 (2018-03-19)

• Implemented pinch-to-zoom camera functionality for devices supporting it (currently available only in Chrome).
• Added new enablePinchToZoom option to BarcodePicker.create to enable/disable pinch-to-zoom (when available).

2.0.0 (2018-03-15)

• Added new BarcodePicker.reassignOriginElement function to re-assign the BarcodePicker to a different HTML element.
