Products.remember is now undisruptive when present but not installed, not affecting operation of non-remember sites in the same instance. Sites that have Products.remember installed can now quick-uninstall to revert to plain operation. (The uninstall is not complete, however - see change log notes.)
Products.remember membership now provides for email-address based logins and respects "Use email address as login name" Site Setup / Security setting.
Many internal changes for Plone 4 and Membrane 2 compatibility, JS schemata/filedsets, and modernized GenericSetup and update configuration.
Products.remember is packaged using Python's setuptools package management infrastructure. Remember can be made available to your Zope instance by installing the Products.remember package into your Zope's python environment, using either buildout from pypi and/or with easy_install or 'python setup.py install'.
Products.remember is installed into a Plone site by the application of a GenericSetup extension profile. You can do this when creating a new site by selecting remember from the list of available setup profiles when you are creating the site. In an existing site, you can use Plone's regular product installation interface.
