I noticed the following change in the Blogger Data API:

"The current version of Blogger now also supports Google's Account Authentication for Installed Applications system (also known as ClientLogin), so if your client is a desktop application, it should support that authentication system in order to work with both versions of Blogger."

Not sure when this happened but it must have been relatively recently. However, in trying to post to an old account using this method just now, I'm getting a "404 resource not found" response. Meanwhile, I am still able to post successfully to an old account using basic authentication.

Questions:

1. Is ClientLogin Account Authentication now in fact enabled for old accounts? (If so, I'll start looking for the bug in my code.)

2. When will basic authentication be disabled for old accounts?

3. Is there a way to programmatically distinguish between old and new accounts? I expect this distinction will be moot once ClientLogin Account Authentication is functional for old accounts. Still, if there were a more reliable way to distinguish, it might help simplify some coding issues.

4. Now that Blogger is out of beta, can we expect the url to which http requests are posted to be stable as http://www2.blogger.com?

If there is a page answering these questions, I'll be happy to be directed there.

In the meantime, anyone who has tested out my Greqo library for PHP, be advised that it is broken until I can resolve these issues. I apologize for any inconvenience.
