Release 4.0.0-beta.5

4.0.0-beta.5 (2025-08-28)

‼️ Upgrade Guide

• Since MMKV is now a fully native HybridObject, it's now longer new MMKV(...), but createMMKV(...).
• For performance and safety reasons, the core MMKV library no longer supports 32-bit. (See MMKV: Prerequisites) So in your gradle.properties, remove the 32-bit architectures and just keep the 64-bit ones:

  - reactNativeArchitectures=armeabi-v7a,arm64-v8a,x86,x86_64
  + reactNativeArchitectures=arm64-v8a,x86_64

  On iOS, 64-bit has been the default for years.
• react-native-mmkv is now a Nitro Module - so you need to install react-native-nitro-modules too.
• The MMKV.delete(...) method has been renamed to MMKV.remove(...) (because delete is a reserved keyword in C++)

✨ Features

• Add useMMKVKeys() (#867) (e2fa9f9)
• Rewrite to a Nitro Module (#862) (60b2d6b)

🐛 Bug Fixes

• Also clear memory cache in trim() (30e48c9)
