 ### Enhancements
-* None
+* ThreadSafeReference no longer pins the source transaction version for anything other than a Results backed by a Query. (Core upgrade)
+* A ThreadSafeReference to a Results backed by a collection can now be created inside a write transaction as long as the collection was not created in the current write transaction. (Core upgrade)
+* Synchronized Realms are no longer opened twice, cutting the address space and file descriptors used in half. (Core upgrade)
 
 ### Fixed
-* None
+* If an object with a null primary key was deleted by another sync client, the exception `KeyNotFound: No such object` could be triggered. (Core upgrade)
+* Fixed a race condition that could result in an assertion `m_state == SyncUser::State::LoggedIn` if the app previously crashed during user logout. (Core upgrade)
