# MaxScale 25.10.3 Release Notes
Release 25.10.3 is a GA release.
**Release Date:** 15 Jun 2026
This document describes the changes in release 25.10.3, when compared to the previous release in the same series.
If you are upgrading from an older major version of MaxScale, please read the [upgrading document](/docs/maxscale/maxscale-management/deployment/upgrading-maxscale.md) for this MaxScale version.
For any problems you encounter, please consider submitting a bug report on [our Jira](https://jira.mariadb.org/projects/MXS).
## New Packages
Although a maintenance release, MaxScale 25.10.3 introduces some significant new functionality that, in order to not change the dependencies of exiting packages, are delivered in packages of their own.
### maxscale-exasol
Contains [exasolrouter](/docs/maxscale/reference/maxscale-routers/maxscale-exasolrouter.md), a MaxScale router that is capable of routing requests to an Exasol Analytics Engine.
### maxscale-maxctrl2
Contains a reimplemenation of maxctrl. The primary differences to maxctrl are
* implemented in C++, so there is no dependency on node.js anymore, and
* provides TAB-completion, which makes interactive use significantly simpler.
Otherwise it is intended to be functionally equivalent with maxctrl.
