+4.4.0 Release notes (2020-03-26)
+=============================================================
+
+Swift 4.0 and Xcode 10.3 are now the minimum supported versions.
+
+### Enhancements
+
+* Allow setting the `fileUrl` for synchronized Realms. An appropriate local
+  path based on the sync URL will still be used if it is not overridden.
+  ([PR #6454](https://github.com/realm/realm-cocoa/pull/6454)).
+* Add Xcode 11.4 binaries to the release package.
+
+### Fixed
+
+* None.
+
+### Compatibility
+
+* File format: Generates Realms with format v9 (Reads and upgrades all previous formats)
+* Realm Object Server: 3.21.0 or later.
+* Carthage release for Swift is built with Xcode 11.4.
+
+4.3.2 Release notes (2020-02-06)
+=============================================================
+
+### Enhancements
+
+* Similar to `autoreleasepool()`, `realm.write()` now returns the value which
+  the block passed to it returns. Returning `Void` from the block is still allowed.
+
+### Fixed
+
+* Fix a memory leak attributed to `property_copyAttributeList` the first time a
+  Realm is opened when using Realm Swift. ([#6409](https://github.com/realm/realm-cocoa/issues/6409), since 4.0.0).
+* Connecting to a `realms:` sync URL would crash at runtime on iOS 11 (and no
+  other iOS versions) inside the SSL validation code. (Since 4.3.1).
+
+### Compatibility
+
+* File format: Generates Realms with format v9 (Reads and upgrades all previous formats)
+* Realm Object Server: 3.21.0 or later.
+* Carthage release for Swift is built with Xcode 11.3.
+
+### Internal
+
+* Upgraded realm-sync from 4.9.4 to 4.9.5.
+
