 ### Breaking changes
 
+* SharedGroup class removed. New DB class added allowing you to specify the Realm file
+  only once regardless of the number of threads.
+* New Transaction class added, inheriting from Group. Transactions are produced by DB.
+* TransactionRef added to provide reference to a Transaction. This is a std::shared_ptr.
+* Old export_for_handover/import_from_handover has been removed. Handover is now direct
+  from one transaction to another, using a new method Transaction::import_copy_of().
 * 'begin' argument removed from Query::count();
 * Table::optimize replaced with explicit Table::enumerate_string_column. It will enumerate
   column unconditionally.
 * TableView::num_attached_rows() no longer available. get(), front, back()... and similar
   functions will throw `InvalidKey` if the referenced object has been deleted.
 * Removed the ability to sort a linklist according to some property of the target table. This
   operation is not supported by the sync protocol and allegedly not used in the bindings.

+* Moved `get_uncommitted_changes()` from `History` class to `Replication` class. This removes the

 * Column identifier changed from size_t to ColKey. This identifier is subsequently
   used when accessing/mutating the data and when making queries.
 * Table identifiers changed from size_t to TableKey.

-* None.
+* Parser improvements:
+    - Support subquery count expressions, for example: "SUBQUERY(list, $x, $x.price > 5 && $x.colour == 'blue').@count > 1"
+        - Subqueries can be nested, but all properties must start with the closest variable (no parent scope properties)
+    - Support queries over unnamed backlinks, for example: "@links.class_Person.items.cost > 10"
+        - Backlinks can be used like lists in expressions including: min, max, sum, avg, count/size, and subqueries
+    - Keypath substitution is supported to allow querying over named backlinks and property aliases, see `KeyPathMapping`
+    - Parsing backlinks can be disabled at runtime by configuring `KeyPathMapping::set_allow_backlinks`
+    - Support for ANY/SOME/ALL/NONE on list properties (parser only). For example: `ALL items.price > 10`
+    - Support for operator 'IN' on list properties (parser only). For example: `'milk' IN ingredients.name`
