 # Breaking Changes
 
+## 0.43.0
+
+* In all databases except MySQL, MariaDB, and SQL Server, the `ubyte()` column now maps to data type `SMALLINT` instead of `TINYINT`, which allows the full range of 
+`UByte` values to be inserted without any overflow.
+Registering the column on a table also creates a check constraint that restricts inserted data to the range between 0 and `UByte.MAX_VALUE`.
+If a column that only uses 1 byte of storage is needed, but without allowing any non-negative values to be inserted, please use a signed `byte()` column
+instead with a manually created check constraint:
+```kotlin
+byte("number").check { it.between(0, Byte.MAX_VALUE) }
+// OR
+byte("number").check { (it greaterEq 0) and (it lessEq Byte.MAX_VALUE) }
+```
+* In all databases except MySQL and MariaDB, the `uint()` column now maps to data type `BIGINT` instead of `INT`, which allows the full range of `UInt` values to 
+be inserted without any overflow.
+Registering the column on a table also creates a check constraint that restricts inserted data to the range between 0 and `UInt.MAX_VALUE`.
+If a column that only uses 4 bytes of storage is needed, but without allowing any non-negative values to be inserted, please use a signed `integer()` column
+instead with a manually created check constraint:
+```kotlin
+integer("number").check { it.between(0, Int.MAX_VALUE) }
+// OR
+integer("number").check { (it greaterEq 0) and (it lessEq Int.MAX_VALUE) }

 * [SQLite] The table column created using `date()` now uses TEXT datatype instead of DATE (which the database mapped internally to NUMERIC type).
