+## Upgrading from Spark SQL 3.5.1 to 3.5.2
+
+- Since 3.5.2, MySQL JDBC datasource will read TINYINT UNSIGNED as ShortType,
while in 3.5.0 and 3.5.1, it was wrongly read as ByteType.
Review Comment:
`3.5.0 and 3.5.1, it was wrongly read as ByteType` part seems to conflict
with the following section, `Upgrading from Spark SQL 3.5.0 to 3.5.1`'s `
TINYINT UNSIGNED as ByteType, while in Spark 3.5.0 and below, they were read as
IntegerType` line.
