NEW
- Added compatibility for CSP (Content Security Policy).

IMPROVED
- Optimized workflow for QRCode/DataMatrix/Aztec code recognition. A QRCode/DataMatrix/Aztec barcode zone will be submitted to the deblurring process when its decoding results vary with different binarization arguments.
- Reduced the error rate of 1D barcode recognition, resulting in a higher chance to successfully confirm a 1D barcode result whose confidence is not extremely high.
- Reduced the possibility of conflicts with neighbour barcodes, improving the precision of the zone to be deleted when a barcode is recognized successfully.
- Super large-size (4096x4096 pixels) images can be processed and decoded.
- The license key can be written in the script label.
Fixed
- Enhanced the robustness of the image processing algorithm. This resolved segmentation faults when a 0-size image is passed to our SDK or when there are a few small barcode zones which require spatial transformation.
- Small fixes and tweaks.
