 * Fixed an error where performing a query like "{1, 2, 3, ...} IN list" where the array is longer than 8 and all elements are smaller than some values in list, the program would crash. ([realm/realm-core#6545](https://github.com/realm/realm-core/pull/6545), since v10.20.0)  
 * Performing a large number of queries without ever performing a write resulted in steadily increasing memory usage, some of which was never fully freed due to an unbounded cache. ([realm/realm-core#6530](https://github.com/realm/realm-core/pull/6530), since v10.19.0)  
 * Partition-Based to Flexible Sync Migration for migrating a client app that uses partition based sync to use flexible sync under the hood if the server has been migrated to flexible sync is officially supported with this release. Any clients using an older version of Realm will receive a "switch to flexible sync" error message when trying to sync with the app. ([realm/realm-core#6554](https://github.com/realm/realm-core/issues/6554), since v11.9.0)
+* Fix deprecated namespace method warning when building for Android ([#5646](https://github.com/realm/realm-js/issues/5646))
