1.12.10
  • New feature:

    Secure Sockets Layer (SSL) encryption is supported for dedicated proxy endpoints.

  • Bugs fixed:
    • The bug that causes SSL connection exceptions on an RDS instance is fixed. These exceptions occur if the RDS instance runs MySQL 8.0.
    • The bug that prevents the enabled dedicated proxies from properly routing new requests to an RDS instance is fixed. This exception occurs if the RDS instance is restored to normal from an abnormal state.
1.12.7
  • New features:
    • The SHOW FULL PROCESSLIST statement is supported.
    • The syntax for XA transactions is supported.
  • Bugs fixed:
    • The bug that causes errors in executing the SHOW PROCESSLIST statement on an RDS instance is fixed. These errors occur if the RDS instance runs MySQL 8.0.

1.11.12
  • New feature:

    The transaction connection pool feature is supported. For more information, see Connection pool.

  • Bugs fixed:
    • The bug that prevents new requests over the previous persistent connections to an RDS instance from being routed to the RDS instance is fixed. This exception occurs if the RDS instance is restored to normal from an abnormal state. The bug is fixed by optimizing the mechanism that is used to balance loads among persistent connections.
    • The bug that prevents the PREPARE statement from being sent in unicast mode is fixed by optimizing the syntax of the PREPARE statement.
    • The bug that causes failures in connecting MySQL 5.7 databases to MySQL 5.6 databases is fixed. These failures occur if the Deprecate EOF feature is enabled.
    • The bug that causes disconnections to an RDS instance is fixed. These disconnections occur if stored procedures are invoked to modify the RDS instance.
    • The bug that causes a client to report the Packets out of order error is fixed. This error occurs if the size per line exceeds 16 MB for large packets in a result set.
    • The bug that causes failures in terminating transactions on a read-only RDS instance in a timely manner is fixed. These failures occur if the transactions are started by using the SET autocommit=0 statement.
    • The bug that causes a statement to be routed to a read-only RDS instance is fixed. This exception occurs if the statement has LOCK IN SHARE MODE specified.
    • The bug that causes the SELECT handler FROM abc statement to be routed to a read-only RDS instance is fixed. This exception occurs if the statement has FOR UPDATE specified.
    • The bug that causes failures in authenticating a user from more than one host is fixed.
