Download Release Notes Changelog About MariaDB Connector/C

Release date: 12 Nov 2024

This is a Stable (GA) release of MariaDB Connector/C, formerly known as MariaDB Client Library for C.

MariaDB Connector/C 3.4.2 was not released separately but is included in MariaDB Community Server 11.4.4. MariaDB Connector/C 3.4.3 includes additional bug fixes for the Connector and is included in MariaDB Community Server 11.6.2, and 11.7.1.

For a description of this library see the MariaDB Connector/C page.

Notable Changes

  • Added option MARIADB_TLS_VERIFY_STATUS to retrieve status of peer certificate validation via mariadb_get_infov().
  • CONC-690: Due to required cryptographic functions that are part of the TLS crypto libraries the option WITH_SSL=OFF (disabling TLS/SSL) is no longer supported and will result in a build error.
  • CONC-724: Added option MARIADB_OPT_TLS_VERIFICATION_CALLBACK to specify a callback function for peer certificate testing.
  • Man pages are no longer stored in github repository. They can be build with cmake option -DWITH_DOCS=ON (requires pyhon 3 and pandoc).
  • If the environment variable MARIADB_TLS_DISABLE_PEER_VERIFICATION was set, the peer certificate verification will be skipped.
  • CONC-717: Added windows support for the parsec authentication plugin, a new plugin added to MariaDB Server 11.6

Issues fixed:

  • CONC-712: Skip host name verification on local connections
  • CONC-731: Wrong error message if incorrect fingerprint was specified
  • CONC-732: Always set verification callback function, even if peer certificate validation is disabled (OpenSSL)
  • CONC-735: A reconnect doesn't do node failover when using a connection string with multiple hosts
