April 28, 2026 · Permalink

We are pleased to announce the availability of MySQL v8.4 Long-Term Support (LTS) on UpCloud's Managed Databases Service.

What's New

As the first Long-Term Support release in MySQL's updated release lifecycle, MySQL 8.4 focuses on long-term stability, security patches, and critical bug fixes. It introduces refined engine defaults, performance optimizations for InnoDB workloads, and strengthened cryptographic standards. For comprehensive information about new features and structural modifications, please refer to the official MySQL 8.4 release notes.

Deployment Options

You can deploy MySQL 8.4 database instances through the following methods:

Create a new database instance via the UpCloud Control Panel
Upgrade an existing instance to MySQL v8.4 through UpCloud Hub or through the UpCloud API.

UpCloud Managed Databases Service version upgrade, as displayed in the details card of the overview tab in UpCloud Hub — In-place upgrade of an UpCloud Managed Database from MySQL 8.0 to MySQL v8.4

UpCloud Managed Databases Service version upgrade confirmation modal in UpCloud Hub — Confirmation modal for the upgrade of an UpCloud Managed Database to MySQL v8.4

Important Notes

Upgrades are irreversible: Major version upgrades modify data directories permanently. We highly recommend testing the upgrade path on a clone of your service before applying it to your production environments.
Authentication & Legacy Compatibility: MySQL 8.4's has moved on the caching_sha2_password authentication mechanism. However, to ensure seamless, zero-downtime upgrades for existing applications that still rely on legacy drivers, the mysql_native_password plugin remains loaded and available by default.
