修補程式

C, .NET, C++, Android, Java, Python and iOS SDK

• Fixed an issue that happens when calling initLicenseFromLTS if handShakeCode is not set.
• ThreshValueCoefficient is now deprecated. It still works in this version but could be removed in the near future. It is recommended to use ThresholdCompensation instead.

.NET SDK Only

• Fixed a bug that may cause the error ‘Failed to get the address of DBR_CreateInstance’ when initializing DBR.

Android SDK Only

• Fixed a bug when trying to build the project in the release mode with code shrinker enabled.

iOS SDK Only

• Replaced the static library with a dynamic library to avoid compatibility issues with other Dynamsoft products or third-party libraries.
