v2.1.0 / 2025-02-18

Happy Chinese New Year!
This is a breaking change version for the Android/OHOS platform. Read the change log bellow and upgrade carefully.

Changes for All platforms

  • Add the NameSpace feature that easily supports customizing a root directory.
  • Add protection from bad disk records of MMKV files.
  • Fix FileLock not being unlocked on destruction.
  • Improve directory creation on ReadOnly mode.

Android

  • Breaking change: Migrate legacy MMKV in a custom directory to normal MMKV. Historically Android/OHOS mistakenly use mmapKey as mmapID, which will be problematic with the NameSpace feature. Starting from v2.1.0, MMKV will try to migrate them back to normal when possible.
    It's highly recommended that you upgrade to v2.0.2/v1.3.11 first with forward support of normal MMKV in a custom directory.
  • Supports using MMKV directly in C++ code.
  • Improve inter-process locking by using F_OFD_SETLK instead of F_SETLK.
  • Add experimental protection from bad disk records of MMKV files.

HarmonyOS NEXT

  • Breaking change: Migrate legacy MMKV in a custom directory to normal MMKV. Historically Android/OHOS mistakenly use mmapKey as mmapID, which will be problematic with the NameSpace feature. Starting from v2.1.0, MMKV will try to migrate them back to normal when possible.
    It's highly recommended that you upgrade to v2.0.2/v1.3.11 first with forward support of normal MMKV in a custom directory.

  • Improve inter-process locking by using F_OFD_SETLK instead of F_SETLK.
  • Add experimental protection from bad disk records of MMKV files.

iOS/macOS

  • Upgrade to iOS 13, macOS 10.15, and watchOS 6 to support the NameSpace functionality.
