Release Notes for MariaDB Connector/J 3.1.1
MariaDB Connector/J is a lightweight JDBC driver (Type 4) for building applications on top of MariaDB database products with Java 8, Java 11, and Java 17.
This release is compatible with JDBC 4.2.
MariaDB Connector/J 3.1.1 was released on 2023-01-11. This release is of General Availability (GA) maturity.
When Connector/J performs an SSL Handshake, it sets the
CLIENT_SSLcapability flag in the SSL Connection Request Packet, but not in the Handshake Response Packet. (CONJ-1023)
In previous releases, the
CLIENT_SSLcapability flag is not required to be set in the Handshake Response Packet, so this issue is only noticed when inspecting the network traffic.
Starting with this release, Connector/J sets the
CLIENT_SSLcapability flag in both the SSL Connection Request Packet and in the Handshake Response Packet.
When running the client on a machine with a non-fixed-offset timezone, the
timezone=autoJDBC option fails with the error: (CONJ-1026)
``Setting configured timezone 'auto' fail on server.``
When mapping the deprecated arguments
disableSslHostnameVerificationto the new
sslModeargument, there can be issues due to different handling of case sensitivity in code that handles argument names. (CONJ-1032)
org.mariadb.jdbc.client.socket.impl.PacketWriter.writeAscii(), the string can be written to the buffer twice. (CONJ-1036)
