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

MariaDB Connector/C 3.3.12 was not released separately but is included in [MariaDB Community Server 10.6.20](/docs/release-notes/community-server/10.6/10.6.20.md), [10.11.10](/docs/release-notes/community-server/10.11/10.11.10.md), and [11.2.6](/docs/release-notes/community-server/old-releases/11.2/11.2.6.md).

## Notable changes

* Added TLSv1.3 support for Schannel (Windows)
* Added new option -DWITH\_BOOST\_CONTEXT. CMake option -DWITH\_BOOST\_CONTEXT=ON adds boost::context as a dependency of libmariadb to provide a fallback on non-natively supported architectures. boost::context is preferred over ucontext when both are available.

## Issues fixed:

* Fixed possible crash if not default plugin was loaded.
* [CONC-730](https://jira.mariadb.org/browse/CONC-730): Undefined behavior in the reference ed25519 implementation
* [CONC-527](https://jira.mariadb.org/browse/CONC-527): Fixed error "SEC\_E\_ALGORITHM\_MISMATCH" connecting Windows client to Ubuntu
* [CONC-735](https://jira.mariadb.org/browse/CONC-735): A reconnect doesn't do node failover when using a connection string with multiple hosts
* [MDEV-34859](https://jira.mariadb.org/browse/MDEV-34859): Failed to initialise non-blocking API on OpenBSD arm64
