# Connector/R2DBC 1.2.0 Release Notes

## Overview

MariaDB Connector/R2DBC is a non-blocking interface between Java applications and MariaDB Server. MariaDB Connector/R2DBC enables the development of Java 8+ applications for MariaDB database products.

**Release date:** 23 Feb 2024

MariaDB Connector/R2DBC 1.2.2 is a [***Stable***](https://github.com/mariadb-corporation/mariadb-docs/blob/main/community-server/about/release-criteria.md) ***(GA)*** release.

This release is compatible with MariaDB Connector/R2DBC 1.1 and will therefore also be the maintenance path for version 1.1. This release is compatible with [R2DBC 1.0.0](https://r2dbc.io/spec/1.0.0.RELEASE/spec/html/) specification.

## Notable Changes

* New timezone option ([R2DBC-93](https://jira.mariadb.org/browse/R2DBC-93))
  * The new timezone option can have 3 types of values:
    * disabled (default) : connector doesn't change timezone
    * auto : connector will set timezone connection variable to java default timezone
    * : connector will set connection variable to the specified timezone. Compared to auto, this avoids having some additional exchange with the server at connection creation
    * Examples:

r2dbc:mariadb://user:pwd\@localhost:3306/db?timezone=+5:00r2dbc:mariadb://user:pwd\@localhost:3306/db?timezone=autor2dbc:mariadb://user:pwd\@localhost:3306/db?timezone=America/New\_York

* The recommended setting for timezone is auto.
* Add support for connection redirection ([R2DBC-66](https://jira.mariadb.org/browse/R2DBC-66))
  * With MariaDB Community Server 11.3.1 a new global variable redirect\_url value has been added, supported format:

```
{mariadb/mysql}://[<user>[:<password>]@]<host>[:<port>]/
```

* When set, all existing connections will be redirected to the designated URL values when appropriate. A connection will only be redirected when no transaction is active.
* Example for enabling the redirection:

```sql
SET @@global.redirect_url="mariadb://somehost:3306/"
```

* The redirection feature is enabled by default. It can be disabled by setting the new option permitRedirect to FALSE, which will result in ignoring the redirection URL.

## Issues Fixed

* Properly end connection (in place of RST TCP packet) ([R2DBC-92](https://jira.mariadb.org/browse/R2DBC-92))
* Failover High availability mode r2dbc:mariadb:\[sequential|loadbalancing]:... wrongly parsed ([R2DBC-86](https://jira.mariadb.org/browse/R2DBC-86))
* Compatibility with [mariadb 11.1.1](https://mariadb.com/docs/release-notes/community-server/old-releases/11.1/11.1.1) ([R2DBC-87](https://jira.mariadb.org/browse/R2DBC-87))
* Java 8 compatibility regression ([R2DBC-88](https://jira.mariadb.org/browse/R2DBC-88))
* Ensure respecting server collation ([R2DBC-91](https://jira.mariadb.org/browse/R2DBC-91))
* Session tracking wrong implementation when multiple system variable changes ([R2DBC-94](https://jira.mariadb.org/browse/R2DBC-94))
