**Release date:** 20 July 2017

This is a [***Stable***](/docs/release-notes/community-server/about/release-criteria.md) ***(GA)*** release of the MariaDB\
Connector/C, formerly known as MariaDB Client Library for C.

**For a description of this library see the**[**MariaDB Connector/C**](/docs/connectors/mariadb-connector-c.md) **page.**

## Features

* Array support for prepared statements (bulk operations)
* TLS/SSL support for GnuTLS, Windows SChannel and LibreSSL
* Support for passphrase protected keys
* SHA256 authentication plugin

## New API functions

* mariadb\_get\_info and mariadb\_get\_infov (variable argument list): for obtaining general and connection specific values.
* mariadb\_get\_charset\_by\_name and mariadb\_get\_charset\_by\_nr: returns character set information for a given internal number or name of character set. These functions have been previously used internally by MariaDB Connector/ODBC and are now exported, so they can be used also within plugins.
* mysql\_reconnect which was used internally before (if the option MYSQL\_OPT\_RECONNECT was set) is now part of the API and can be used by applications and plugins to reestablish a failing connection
* mariadb\_cancel: aborts a connection immediately by making all subsequent read/write operations fail
* mariadb\_stmt\_execute\_direct: prepares and executes a prepared statement for one time execution
* mysql\_stmt\_warning\_count returns: the number of warnings from the last executed statement
* mysql\_reset\_connection: resets the current connection and clears session state
* Functions for obtaining session state changes:
  * mysql\_session\_track\_get\_first()
  * mysql\_session\_track\_get\_next()
