### Enhancements * Add support for React Native 0.80.0, by migrating to a pure C++ TurboModule. ([#7029](https://github.com/realm/realm-js/pull/7027)) * 16KB page size support for Android 15+ ([#7019](https://github.com/realm/realm-js/pull/7019)). If you are using Android Gradle Plugin (AGP) 8.5 or lower, you will need to [enable legacy packaging](https://developer.android.com/guide/practices/page-sizes#update-packaging). ### Fixed * Fix numerous crashes on Android, by explicitly setting C++ standard (C++20) when building pre-builds. ([#7027](https://github.com/realm/realm-js/pull/7027), since v12.11.0) ### Compatibility * React Native >= v0.71.4 * Realm Studio v15.0.0. * File format: generates Realms with format v24 (reads and upgrades file format v10). ### Internal * Upgrade React Native version in the test app to 0.80.0. * Upgrade NDK to 27.1.12297006 and Android API level 24, to match React Native latest. * Upgraded Realm Core from v14.13.5 to v14.14.0 <!-- * Either mention core version or upgrade --> <!-- * Using Realm Core vX.Y.Z --> <!-- * Upgraded Realm Core from vX.Y.Z to vA.B.C -->

### Fixed * Fix setting `List` values from themselves (either through assignment or the `Realm#create` method). Before this fix, the list would be emptied before being iterated, resulting in elements being removed from the list.

### Fixed * Closing and opening a realm before a token refresh is completed, would result in two sync sessions both try to start synchronizing the realm when the refreshes do complete, leading to a crash with a MultipleSyncAgents exception. ([realm/realm-core#8064](https://github.com/realm/realm-core/issues/8064)) * Migrating primary key to a new type without migration function would cause an assertion to fail. ([realm/realm-core#8045](https://github.com/realm/realm-core/issues/8045), since Realm JS v10.0.0) * Committing a subscription set prematurely released a read lock, which may have caused a BadVersion exception with an error like `Unable to lock version XX as it does not exist or has been cleaned up` while changing subscriptions. ([realm/realm-core##8068](https://github.com/realm/realm-core/pull/8068), since Realm JS v12.13.0) ### Compatibility * React Native >= v0.71.4 * Realm Studio v15.0.0. * File format: generates Realms with format v24 (reads and upgrades file format v10). ### Internal * Upgraded Realm Core from v14.13.1 to v14.13.5.

([#6908](https://github.com/realm/realm-js/issues/6908) since React Native v0.76.0). * Fix build failure from duplicate libreactnative.so files. I.e. "2 files found with path 'lib/arm64-v8a/libreactnative.so' from inputs" ([#6918](https://github.com/realm/realm-js/issues/6918), since v12.13.2) * Having a query with a number of predicates ORed together may result in a crash on some platforms (strict weak ordering check failing on iphone) ([realm/realm-core#8028](https://github.com/realm/realm-core/issues/8028), since Realm JS v20.0.0) ### Compatibility * React Native >= v0.71.4 * Realm Studio v15.0.0. * File format: generates Realms with format v24 (reads and upgrades file format v10). ### Internal * Refactored Android filesystem platform helpers.
