“Plone 2.5.3 includes fixes for the recently discovered potential Zope XSS vulnerabilities, and is a mandatory update for all Plone 2.5 users. Please apply this update as soon as you can. The potential security issue only affects sites that allow untrusted users to register.”

The release also includes improvements to the upgrade/migration code, i18n, and a number of minor bug-fixes. If you are upgrading from an earlier release, migration will now be somewhere between 2-6 times faster, depending on which release you’re upgrading from.
