Flexible sync subscription state will change to SyncSubscriptionState.pending (RLMSyncSubscriptionStatePending) while waiting for the server to have sent all pending history after a bootstrap and before marking a subscription as Complete. (#5795)
Add custom column names API, which allows to set a different column name in the realm from the one used in your object declaration.
```
class Person: Object {
    @Persisted var firstName: String
    @Persisted var birthDate: Date
    @Persisted var age: Int

    override class public func propertiesMapping() -> [String: String] {
        ["firstName": "first_name",
         "birthDate": "birth_date"]
    }
}
```
This is very helpful in cases where you want to name a property differently from your Device Sync JSON schema. This API is only available for old and modern object declaration syntax on the RealmSwift SDK.
Flexible sync bootstraps now apply 1MB of changesets per write transaction rather than applying all of them in a single write transaction. (Core PR #5999).

Fix a race condition which could result in "operation cancelled" errors being delivered to async open callbacks rather than the actual sync error which caused things to fail (Core PR #5968, since the introduction of async open).
Fix database corruption issues which could happen if an application was terminated at a certain point in the process of comitting a write transaciton. (Core PR #5993, since v10.21.1)
@AsyncOpen and @AutoOpen would begin and then cancel a second async open operation (PR #8038, since v10.12.0).
Changing the search text when using the searchable SwiftUI extension would trigger multiple updates on the View for each change (PR #8038, since v10.19.0).
Changing the filter or search properties of an @ObservedResults or @ObservedSectionedResults would trigger up to three updates on the View (PR #8038, since v10.6.0).
Fetching a user's profile while the user logs out would result in an assertion failure. (Core PR #6017, since v10.8.0)
