Updated Plone Release Schedule and Policy

As of January 15, 2024, Plone has published an updated timeline of maintenance and support for Plone releases.

Changes from the previous Release Schedule

Release schedule includes Plone releases 5.2, 6.0, 6.1, 6.2, and 7.0.

  • All Plone 6 minor versions get security support until 2027-12-31, 5 years after Plone 6.0.0 was released.

  • Plone 6.0.x with Volto 16.x gets maintenance support until 2024-12-31, 2 years after Plone 6.0.0 was released. Use this for your site when your primary concern is stability.

  • Maintenance support for Plone 6.1.x stops once 6.2.0 is released. Maintenance for Plone 6.2.x stops once 7.0.0 is released. Use this for your site when you want the latest features and most modern approaches.

  • Plone 5.2.x is out of maintenance support. It gets security support until 2024-10-31. Older Plone versions are unsupported.

Changes from the previous Release Policy

Release policy includes Security support, Maintenance support, and Volto.

  • Support for Volto (the default frontend in Plone 6) is integrated in the Plone release policy.

  • Instead of dropping security support on all but the last minor version once the next major version is released, we give security support to all minor versions within a major release until the same end date.

  • The first minor version, for example 6.0.x, now has longer maintenance support, with a fixed duration of 2 years from the date of its release.

  • Other minor releases (for example 6.1.x and 6.2.x) will drop maintenance support when the next minor or major version is final, instead of having an overlap. They get security support during the same period as the first minor version.
