Tencent/MMKV v1.3.6

on GitHub

v1.3.6 / 2024-07-05

Changes for All platforms

• The Core library now upgrades the C++ standard from C++17 to C++20 to make the most of morden C++ feature such as Concept & unordered containers with std::string_view as key. From now on, if you build MMKV by source (iOS, Windows, POSIX, etc), you will need a C++ compiler that supports the C++20 standard. If you only use MMKV in binary (Android, OHOS, etc), this upgrade of the C++ compiler is not required.
• The key type changes from std::string to std::string_view, to avoid unnecessary string construction and destruction when the key is a raw string.

Android

• Use the latest ashmem API if possible.
• Use the latest API to get the device API level.

Flutter

• MMKV will try to load libmmkv.so before Dart code, to reduce the error of loading library in Android.

HarmonyOS NEXT

• Fix a bug that a String value might get truncated on encoding.
• MMKV returns undefined when a key does not exist, previously a default value of the type (false for boolean, 0 for number, etc) is returned.
• Add the feature to encode/decode a float value.
• Add the feature to encode/decode a TypedArray value.
• Support encoding a part of an ArrayBuffer.

iOS/macOS

• Hide the default NSObject.initialize() from Swift/ObjC to prevent potential misuse.

POSIX

• Support encode/decode std::vector<T> or std::span<T> values, with T as primitive types.
• Fix a compile error on Linux env.
• Fix a compile error on the GNU compiler.
• Fix a compile error with some old version of zlib (on CentOS).

Python

• Python now runs on Windows. Check out the latest wiki for instructions.
