+## Major changes
+
+### All Processing Operators Updated to Column-Based Events
+
+All processing operators now use the column-based event format, leading to better performance. 
+However, some sources and sinks for connectors still use the row-based event format. 
+Additionally, a few functions continue to rely on the row-based event format.
+
+### MongoDB Source Support
+
+This release adds support to read data from MongoDB, this includes using 
+MongoDBs change stream to directly react on data changes.
+
+### SQL Server Support for Stream State Persistence
+
+You can now store the stream state in SQL Server. For setup instructions, refer to the documentation:
+https://koralium.github.io/flowtide/docs/statepersistence#sql-server-storage
+
+### Timestamp with Time Zone Data Type
+
+A new data type for timestamps has been added. 
+This ensures that connectors can correctly use the appropriate data type, especially when writing. 
+For example, writing to MongoDB now uses the BSON Date type.
+
+
+## Minor Changes
+
+### Virtual Table Support
+
+Static data selection is now supported. Example usage:
+
+```
+INSERT INTO output 
+SELECT * FROM 
+(
+  VALUES 
+  (1, 'a'),
+  (2, 'b'),
+  (3, 'c')
+)
+```
