+vNext (TBD)
+------------------
+
+NOTE!!! You will need to upgrade your Realm Object Server to at least version 3.11.0 or use Realm Cloud. If you try to connect to a ROS v3.10.x or previous, you will see an error like Wrong protocol version in Sync HTTP request, client protocol version = 25, server protocol version = 24.
+
+### Enhancements
+* Download progress is now reported to the server, even when there are no local changes. This allows the server to do history compaction much more aggressively, especially when there are many clients that rarely or never make local changes. ([#1772](https://github.com/realm/realm-dotnet/pull/1772))
+* Reduce memory usage when integrating synchronized changes sent by ROS.
+
+### Fixed
+* Fixed a bug that could lead to crashes with a message such as `Assertion failed: ndx < size() with (ndx, size()) = [742, 742]`.
+
+### Compatibility
+* Realm Object Server: 3.11.0 or later.
+* APIs are backwards compatible with all previous releases in the 3.x.y series.
+* File format: Generates Realms with format v9 (Reads and upgrades all previous formats)
+
+### Breaking Changes
+* The deprecated method `realm.SubscribeToObjectsAsync` has been removed in this version. ([#1772](https://github.com/realm/realm-dotnet/pull/1772))
+
+ ### Internal
+* Upgraded Sync from 3.9.2 to 3.14.11 and Core from 5.8.0 to 5.12.7.
