     Added support for Code_11.
     Added support for Pharmacode.
     The return value of the method getIdleInstancesCount is changed from 0 to -1 when all local instances become inactive.
     Optimized the algorithm on decoding PatchCode. The barcode reader will be able to detect the PatchCodes even when they are far away from the edge of the image.
     Optimized the read rate of GS1 Databar symbols.
     Optimized the performance of localizationMode.OneDFastScan.
     Optimized the confidence scoring system for PDF417 codes.
     Added new deformation resisting modes DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE to optimize the deformation resisting algorithm for QRCode and DataMatrix codes.
     Added function 1 symbol character code of the GS1-128 at the beginning of the barcodeText.
     Added BF_CODE_11 under Enumeration EnumBarcodeFormat to specify newly supported barcode format, Code 11.
     Added BF2_PHARMACODE_ONE_TRACK, BF2_PHARMACODE_TWO_TRACK and BF2_PHARMACODE under Enumeration EnumBarcodeFormat_2 to specify newly supported barcode format, Pharmacodes.
     Added a new error code DBRERR_PHARMACODE_LICENSE_INVALID which will be returned when the license of Pharmacode is invalid.
     Added DRM_BROAD_WARP, DRM_LOCAL_REFERENCE and DRM_DEWRINKLE under Enumeration EnumDeformationResistingMode to apply new deformation resisting modes.
     Added a parameter FormatSpecification.VerifyCheckDigit
     Added an Argument ConfidenceThreshold to the LocalizationModes mode arguments.
     Added a method InitLicense to initialize license key and activate the SDK.
     Changed value of BF_ONED under Enumeration EnumBarcodeFormat to 0x003007FF to have BF_CODE_11 combined.
     Changed value of BF_ALL under Enumeration EnumBarcodeFormat to 0xFE3FFFFF to have BF_CODE_11 combined.
     Fixed a bug that might cause a crash when using multiple threads for barcode decoding.
     Other small fixes and tweaks.
     The following items are now deprecated. They still work in this version but could be removed in the near future.
