This package contains various visual components for Plone, such as viewlets and general views.
- the 2.2.x series is for use in Plone 4.2
- the 2.3.x series is for use in Plone 4.3 (versions below 2.3.2 may also work with Plone 4.2)
- the 2.5.x series is for use in Plone 5.0
- the 2.8.x series (currently master branch) is for use in Plone 5.1
Using other combinations might work, but you may find getting support for that harder.
If you are using Plone < 4.3.5 and you are using dexterity items and plone.app.contenttypes, you might want to pin the latest 2.3.x version of this package.
