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)
