v5.0.4

• iOS fixes:
  • Fixed some issues related to internal camera management

v5.0.3

• iOS fixes:
  • Fixed problems with string localizations

v5.0.2

• iOS fixes:
  • CFBundleSUpportedPlatforms removed from Info.plist files
  • Applying affine transformation to PPQuadrangle now correctly assigns points.
  • When using both Direct API and PPCameraCoordinator, scanning results will now be correctly outputted to PPCoordinatorDelegate and PPScanningDelegate respectively
  • Fixed crashes related to camera permissions and added dummy view when camera permission is disabled
  • Fixed issues related to topLayoutGuide on iOS6

v5.0.1

• iOS updates:
  • Added option to mirror input images to PPCameraSettings
• iOS bugfixes:
  • ITF reader now accepts barcode sizes ranging between [6,50]

v5.0.0

• iOS updates:
  • Implemented PPCameraCoordinator. PPCameraCoordinator assumes the role of PPCoordinator from previous versions while new PPCoordinator is used for Direct API (image processing without camera out management).
  • Increased speed of scanning for barcode type recognizers.
  • Implemented PPImage. When using Direct API you can wrap UIImage and CMSampleBufferRef into PPImage to ensure optimal performance.
  • Improved performance of Direct API. In addition, you can now use Direct API with your own camera management without any performance drawbacks.
  • Added method isCameraPaused to PPScanningViewController.
  • Added option to fllip input images upside down for processing with cameraFlipped property of PPCameraSettings.
  • Implemented PPViewControllerFactory for managing creation of PPScanningViewController objects.
  • PPImageMetadata now contains PPImageMetadataType property, which describes which image type was outputted.
• iOS bugfixes:
  • New Direct API fixed possible deadlocks when sending large amounts of data

v4.3.0

• Added better integration for Swift

  - Added Nullability Attributes
  - Added modulemap file
  - Added sample app in Swift
  

• Refactored PPMetadataSettings

  - Added debug metadata settings for debugging payslip detection and image processing
  - `successfulScanFrame` renamed to `successfulFrame`
  - `currentVideoFrame` renamed to `currentFrame`
  

• Exposed PPModernViewfinderOverlaySubview overlay subview class in public headers. This enables you to more easily recreate default overlay UI in your custom Overlay view controllers.

• in PPCoordinator, renamed method isScanningUnsupported: to isScanningUnsupportedForCameraType:error:. This was introduced to provide more granularity in checking if scanning is supported.

• PPOverlayViewControllerchanged the way Overlay Subviews are added to the view hierarchy. Instead of calling addOverlaySubview: (which automatically added a view to view hierarachy), you now need to call registerOverlaySubview: (which registers subview for scanning events), and manually add subview to view hierarchy using addSubview: method. This change gives you more flexibility for adding views and managing autolayout and autoresizing masks.

• Localization Macros MB_LOCALIZED and MB_LOCALIZED_FORMAT can now be overriden in your app to provide completely custom localization mechanisms.

• Increased speed of scanning cancellation when Cancel button is pressed.

v4.2.2

• Fixed several issues in USDL parsing
  - implemented special cases for barcodes which don't have keys according to the AAMVA version written in the barcode
  - implemented heuristics for extraction of firstName, middleName, lastName, address, and other fields, if they can be determined based on the other fields.
• Bugfixes and tweaks in camera management code
  - fixed potential deadlock when multiple instances of PPCoordinator objects are instantiated.
  - exiting from the scanning when user presses "cancel" button is now faster
  - fixed race condition which potentially crashed the scanner when user exited and entered camera screen consecutively very fast.

v4.2.1

• Added new callback method to PPScanDelegate which is called when license key is invalid: scanningViewController:invalidLicenseKeyWithError:

v4.2.0

• Added bitcode support for Xcode 7
• Updated USDL parsing. Added better handling of FullName, FullAddress, Height and Weight of cardholder. Added full support for Magnetic PDF417 standard.
• Small performance improvements in iOS camera management.

v4.1.1

• Added special case for scanning some British Columbia DLs
• Stability improvements in USDL scanning
