Release 3.1.0

Changes

• Pipeline attachments structure changed. A 'sources' layer was added to allow attachments from multiple sources to one destination object. This requires a change to AttachmentsCreate: source_name is changed to sources. sources should be a list of AttachmentSourcesCreate items, in which the source_name and mapping can be defined as before.
• Deployment version file upload (versions_file_upload) changed to revisions (revisions_file_upload), which returns a revision and build id.
• Deployment version file download (versions_file_download) changed to revisions (revisions_file_download), for which a revision_id is required. The active revision id can be obtained via versions_get.
• Deployment version status changed. It is now one of ['unavailable', 'building', 'available']. The status of the active build can be obtained using builds_get().
• Request time_last_updated changed to time_started and time_completed.
