- Update to 8.0.30:
Functionality Added or Changed
* X DevAPI: For document-modifying methods that are chained
after modify() and take a document path expression as one of
its arguments (that is, set(), unset(), arrayInsert(),
arrayAppend()), Connector/J now throws an error when the

collations prefixed with utf8_ are now prefixed with utf8mb3_
instead. To go with that change, Connector/J has updated its
character set and collation mapping accordingly in this
release, and users are encouraged to update to Connector/J
8.0.30 to avoid potential issues when working with MySQL
Server 8.0.30 or later.
* A few links in the CONTRIBUTING.md file in the distribution
packages were broken. They have now been fixed or removed.
* The description for the connection property
rewriteBatchedStatements has been corrected, removing the
limitation that server-sided prepared statements could not
take advantage of the rewrite option.
* A spelling error has been fixed in the source file for the
PropertyDefinitions class. Thanks to Weijie Wu for
contributing the fix.
* DatabaseMetaData.getTypeInfo always returned false for
AUTO_INCREMENT for all data types. With this fix, Connector/J
returns the correct value for each data type. Also, the
