This is the first and hopefully the last release candidate for 6.x-1.3. If no blockers show up in a week or so, this will become the official 6.x-1.3.

Bug fixes:

• #364965: Node Radioactivity fatal error on cached pages when using i18n. This is a fix for long-withstanding incompatibility with i18n in certain cases.
• #651060: Incompatibility with PHP 5.3. Fixes some warnings in votingapi-modules.
• #403426: Undefined index: subclasses. Fixes some notices
