API Changes for January 12, 2009

[Matt Sanford]

Here are the changes launched today, 2009-01-12:

Fixed: some methods were defaulting to JSON when no format was
specified. A format must be specified for all API calls.

Security: it was possible to discover the currently logged-in user via
an unauthenticated call to the /statuses/user_timeline method. This is
a potential privacy concern, and was disabled.

Fixed: Atom feeds for timelines incorrectly reported all user profile
pictures as image/png. This may take up to a day to propagate through
all of our caches.

Fixed: Requests with &id= and no value returned a user rather than an
error. Now an error is returned.

Thanks;
