# MariaDB MaxScale 2.0.2 Release Notes
Release 2.0.2 is a GA release.
This document describes the changes in release 2.0.2, when compared to
release [2.0.1](MaxScale-2.0.1-Release-Notes.md).
If you are upgrading from release 1.4.4, please also read the release
notes of release [2.0.0](./MaxScale-2.0.0-Release-Notes.md) and
release [2.0.1](./MaxScale-2.0.1-Release-Notes.md).
For any problems you encounter, please submit a bug report at
[Jira](https://jira.mariadb.org).
## Updated Features
### [MXS-978] (https://jira.mariadb.org/browse/MXS-978) Support for stale master in case of restart
In case where replication monitor gets a stale master status (slaves are down)
and maxscale gets restarted, master loses the stale master status and no writes
can happen.
To cater for this situation there is now a `set server <name> stale` command.
