It says May 28, but help/configuration still returns this:
‘characters_reserved_per_media’ => 23,
‘max_media_per_upload’ => 1,
‘photo_size_limit’ => 3145728,
‘short_url_length’ => 22,
‘short_url_length_https’ => 23,
So does the example at https://dev.twitter.com/docs/api/1.1/get/help/configuration.
I also wonder whether statuses/update_with_media can fully replace statuses/update. In other words, with no “media”, but everything else exactly the same.
When/if you support multiple files, can each image (and video?) be photo_size_limit large, or are we talking aggregate size of all files per update?
A list of what media types can be uploaded (preferably as MIME type), would be a nice-to-have in help/configuration.
