+## 0.6.35
+
+- Add support for unsigned integers in the `Any` driver
+- Add support for unsigned integers in the `postgres` driver
+- Add a `max_size` method to `MySqlTypeInfo` allowing to retrieve the maximum size of the type (for example, `TINYINT(1)` has a maximum size of 1)
+
 ## 0.6.34
 
 - Add support for decoding `DateTime<FixedOffset>` in the `Any` driver
