Plone 5.2 Release

Plone 5.2 is here! This is the 'futureproof' release - we've finally integrated the various Zope forks and got to the latest points releases of all our Python!
Plone 5.2 Release

Plone 5.2 is the latest version of the most fully-featured, open source web content management system. Plone 5.2 is the culmination of over 3.5 years of development that was driven by the looming deadline of January 1, 2020: the impending end of support for Python 2.x.

Python 3 Compatibility

Plone is written in Python, the programming language that has taken the world by storm and is popular for learners, scientists, web-developers and machine-learning alike. Support for Python 3.6, 3.7, and 3.8 is now included with Plone 5.2, opening up the future for Plone’s continuing 20 year reputation for unrivaled security and stability.

Plone 5.2 ships with Zope 4, which itself comes with Python 3 compatibility, Web Server Gateway Interface (WSGI) support, and a new look.

Work on Plone 5.2 began to take shape in January 2016, with a Plone Improvement Proposal (PLIP) to update its dependencies to use early Zope4 versions and culminated in the completion of the proposal to port to Python 3 in February 2019.


Once available as a separate add-on, a REST API is now also included in Plone 5.2, making it even easier to use Plone with modern JavaScript front ends such as Volto (based on React) and to integrate Plone with other applications.

User-Facing and Developer-Focused Changes

But Plone 5.2 isn’t just a backend upgrade: it includes user-facing features such as new dropdown menus, configurable redirects (customizable URL shortening and content linking).

Developers will also find a more pluggable and customizable login mechanism and a modernized virtualenv-based buildout.

Community-driven development

For almost 20 years now, the Plone software has continued to innovate and evolve with the times, and its world spanning community maintains a dynamic schedule of collaborative sprints and an annual conference bringing together its integrators and users, which include corporations, universities, all levels of governments and well-known government agencies.

Feature-rich and ready-to use

Plone is unsurpassed in the out of the box experience it provides for collaboratively creating, maintaining, and managing large amounts of content. Some of its feature highlights include:

  • customizable workflow for controlling how content gets reviewed and published
  • built in content history and version control
  • content rules that automatically take actions, such as notify users or move content based on customizable conditions
  • sophisticated, fine-grained security through permissions, roles, users, groups, and folder- and object-level sharing authorization
  • accessibility compliance, meeting WCAG 2.1 AAA
  • integration with enterprise authentication and authorization via LDAP/ActiveDirectory
  • deployments that scale, whether Docker, on-premise, or in the cloud

We are shipping Plone 5 out of a separate repository,Plope 5 (for Zope and Plone). As we still support Plone 4, we have a huge range of tools and expertise to support your migration of Plone4 assets and infrastructure to Plone5. We would be happy to discuss your requirements and assist you with getting to the latest Plone!
