Version 3.7.6 (2022/09/05)

General change

The integer types used throughout the SDK are now based on the standard types defined in <cstdint> and the UTF-16 character type is now char16_t from c++11. This is not an ABI change, all types have the same size as before, and old compiled plug-ins will still load without any issue in all hosts on all supported systems. But implementations may have to be adopted especially on Windows where the tchar/char16 type was directly used for Windows API's. There are simple casting functions in pluginterfaces/base/fstrdefs.h (see wscast) for easy adoption.
