Plone 5.1

As with all Plone minor version releases, 5.1 includes many bug fixes and under-the-hood improvements, with a modest selection of enhancements visible to users, editors, and site administrators.

Plone 5.1 contains these user-facing improvements:

• Plone pages load faster now with better bundling of JavaScript and CSS resources
• Plone’s built in search indexing is much faster and CPU-efficient
• Plone supports the display of higher resolution HiDPI (“Retina”) images

Content editors and site administrators will find these enhancements:

• Site administrators can create, edit, and manage portal actions (menu items and links) through a new control panel
• Direct linking to groups’ details from the Sharing tab
• New configuration registry control panel lets site administrators export, import, and add new records
• Improved HTML filtering for preventing malicious HTML
• Fine grained control over thumbnail images in portlets and display views
• Support for image rotation metadata: the image will show up with the rotation that the photographer intended
• The default order of search results is now configurable

Plone 5.1 also includes these developer-oriented changes:

• Ability to conditionally import configuration registry records (by checking on the presence or not of specific features and Plone versions)
• Removal of OpenID login support from Plone core
• Removal of the old portal_quickinstaller (may be a breaking change for add-on developers)
