Changes in MySQL Connector/J 8.0.21 (2020-07-13, General Availability)

Version 8.0.21 is the latest General Availability release of the 8.0 series of MySQL Connector/J. It is suitable for use with MySQL Server versions 8.0, 5.7, and 5.6. It supports the Java Database Connectivity (JDBC) 4.2 API, and implements the X DevAPI.

In the documentation for MySQL 8.0.21, we have started changing the term “master” to “source”, the term “slave” to “replica”, the term “whitelist” to “allowlist”, and the term “blacklist” to “blocklist”. There are currently no changes to the product's syntax, so these terms are still present in the documentation where the current code requires their use. See the blog post MySQL Terminology Updates for more information.

• When trying to set a parameter for a PreparedStatement using the method PreparedStatement.setObject(parameterIndex, "false", Types.BOOLEAN), the value was set to true instead of false. (Bug #30911870, Bug #98237)
