Field types for page_id, page_parent_id, and page_order were corrected. The behavior of mt_text_more was fixed. A useless warning when input arrays are empty was removed. The type of user_id was changed.
The CLI version sent a page rather than a post; this has been fixed. \[ is now allowed in posts. --newmedia and --overwrite options have been added to support uploading media. --supportedstatus has been added to list supported status values for --publish. The bug that effectively removed all integer and date fields in a request has been fixed.
