Version 1.3 supports Atom 0.3

Version 1.3 supports Atom 0.3 working draft. It no longer supports Atom 0.1, 0.2, or the unofficial 0.2.1. Old Atom feeds will fail with an "ObsoleteVersion" or "ObsoleteNamespace" error.
This release also features better validation for urn: and tag: URIs, which are commonly used in <id> elements in Atom feeds.
There was one behavioral change to the RSS validation in this release. Previous versions of the RSS Validator would attempt to flag relative URLs within <description>, <content:encoded>, and <xhtml:body>. This rule was wildly unpopular and was not supported by spec text. It was felt at the time that the issue was important for interoperability, and that the spec would soon be updated to address it, but neither of these assumptions turned out to be true. The check has been removed; relative URLs in those elements will no longer be flagged.
