+=head1 BACKWARDS COMPATIBILITY CHANGES
+
+=head2 EXTENSION_ARGS v EXTENSIONS
+
+B<NB>: The extensions were previously configured under the key C<extension_args>. They are now configured under C<extensions>. This prevents the need for double configuration but it breaks extensions in your application if you do not change the name. The old version is supported for now but may be phased out at any time.
+
+As previously noted, L</EXTENSIONS TO OPENID>, I have not tested the extensions. I would be grateful for any feedback or, better, tests.
+
+=head2 FATALS
+
+The problems encountered by failed OpenID operations have always been fatals in the past. This is unexpected behavior for most users as it differs from other credentials. Authentication errors here are no longer fatal. Debug/error output is improved to offset the loss of information. If for some reason you would prefer the legacy/fatal behavior, set the configuration variable C<errors_are_fatal> to a true value.

+=head2 EXTENSIONS TO OPENID
-These are set in your realm. See above.
+The Simple Registration--L<http://openid.net/extensions/sreg/1.1>--(SREG) extension to OpenID is supported in the L<Net::OpenID> family now. Experimental support for it is included here as of v0.12. SREG is the only supported extension in OpenID 1.1. It's experimental in the sense it's a new interface and barely tested. Support for OpenID extensions is here to stay.
