Release notes for Magnolia CMS 6.3.10

LTS release • Delivered on June 26, 2025 • Page updated on July 24, 2025 • Changelog: 17965

Do not upgrade to Magnolia 6.3.10 from Magnolia 6.3.8 and earlier.

Upgrading to Magnolia 6.3.9, 6.3.10, 6.3.11, or 6.3.12 initiates a Marketing Tags version handler task that may cause instances to become unresponsive if the repository contains a large number of versions. See the Known issues page for more information.

The issue has been resolved in the Magnolia 6.3.13 release.

Magnolia 6.3.10 enhances functionality with a new CKEditor 5 General HTML Support plugin, YAML environment variable substitution, and a separate IP security filter. Workflow dialogs now support i18n site-awareness.

This release also fixes security issues, Content-Type header for binaries, REST filter OR operator, UI responsiveness, item order preservation, and SpaRenderer error logs.

Improvements

MAGNOLIA-7918 Extract ipSecurity functionality out of uriSecurity filter to a separate filter

For more, see IP security.

MAGNOLIA-9659 Support environment variable substitution in YAML decoration files

For more, see Interpolate environment variables in light modules.

Any secrets that are substituted in YAML files may be exposed in the Definitions App. Substitutions are turned off by default, and you must be careful when setting the magnolia.yaml.envsubst feature flag to true, especially when you substitute sensitive data.

MGNLCKE-40 Add GeneralHtmlSupport plugin

For more details about the plugin and how to configure it, see CKEditor 5 customization: General HTML Support plugin.
MGNLWORKFLOW-556 Show changes a dialog needs to be site-aware for i18n

Security improvements

MAGNOLIA-9550, MGNLPN-830, MGNLPN-837, MGNLUI-9211

New `allowVariants` property in REST API

MGNLPN-837 introduces a new property called magnolia.personalization.rest.allowVariants, which enables direct retrieval of variant nodes via the REST API. The default value is false. For more details and recommendations, see Retrieving variant nodes.

Third-party library updates

This release comes with third-party library updates, see the Magnolia Third-party library BOM 6.3.10.

Notable updates

BUILD-1025 Upgrade to SnakeYAML 2

There are several changes between SnakeYAML 1.x and 2.x which are explicitly noted as backwards-incompatible or have the potential to break existing code due to altered behavior.

These include API changes, changes in default behavior, and security-driven restrictions. The breaking changes primarily affect:
- Low-level API users (for example, custom parsers or tag handling).
- Applications serializing JavaBeans with read-only properties.
- Code deserializing untrusted YAML without explicit constructor configurations.
If you are using SnakeYAML in your project, consider the changes if you need to update. For more details, see snakeyaml / Changes on Bitbucket.
BUILD-1405 Update info.magnolia.beanutils2:commons-beanutils2 to 2.0.1-magnolia
