- Added RDF support:
* Modules can declare RDF namespaces which are serialized in the tag
for RDFa support.
+- Search engine optimization and web linking:
+ * Added a rel="canonical" link on node and comment pages to prevent
+ duplicate content indexing by search engines.
+ * Added a default rel="shortlink" link on node and comment pages that
+ advertises a short link as an alternative URL to third-party services.
+ * Meta information is now alterable by all modules before rendering.
- Field API:
* Custom data fields may be attached to nodes, users, comments and taxonomy
terms.
