Breaking changes

• Drop Python 3.6 support. Python 3.7 is now the minimum required version.
• Twitter, Instagram, Mastodon:
  • Drop get_activities cache kwarg's support for App Engine memcache interface. It's now only used as a plain dict. get_activities will now make many small modifications, so if you pass an object that implements those as API calls, you'll probably want to batch those separately.

• Atom:
  • Switch to converting AS1 id (instead of url) to Atom id.

• ActivityStreams 2:
  • Translate both url and urls from AS1 into multi-valued AS2 url field.
• Move a number of utility methods from the Source class to a new as1 module: object_type, merge_by_id, is_public, add_rsvps_to_event, get_rsvps_from_event, activity_changed, append_in_reply_to, actor_name, original_post_discovery.
• as1.original_post_discovery: remove deprecated cache kwarg.

Non-breaking changes

  • Fix spec compliance bug: icon and image are singly valued, not multiply valued.
  • Add new is_public method and PUBLIC_AUDIENCE constant.
  • Prefer "objectType": "featured" first in the image field when converting from AS1, last in the icon field. This matches the ActivityPub (Mastodon) convention of using icon for profile pictures and image for header images.

  • to_as1: if an attachment's mediaType is image/..., override objectType and set it to image.
• Twitter
  • Trim alt text in line between post preview and creation
  • Correctly trim Twitter alt text

  • Scraping: extract post id and owner id from data-ft attribute and _ft_ query param more often instead of story_fbid, which is now an opaque token that changes regularly. (facebook-atom#27)
• Instagram
  • Add new Instagram.scraped_json_to_activities method.
• GitHub
  • create and preview: convert profile URLs to @-mentions, eg https://github.com/snarfed to @snarfed (bridgy#1090).
    • get_activities with activity_id now supports fetch_replies and fetch_likes.
• Reddit
  • Add cache support to get_activities.
• REST API
  • Add new /scraped endpoint that accepts POST requests with silo HTML as input. Currently only supports Instagram. Requires site=instagram, output=... (any supported output format), and HTML as either raw request body or MIME multipart encoded file in the input parameter.
• microformats2
  • Add new extra and body_class kwargs to activities_to_html.
  • When converting u-featured images to AS1, add new non-standard "objectType": "featured" field to distinguish them from u-photo.

Breaking changes

• Drop Python 3.5 support. Python 3.6 is now the minimum required version.

Non-breaking changes

• Add new include_shares kwarg to get_activities, implemented for Twitter and Mastodon. Defaults to True. If False, shares (retweets in Twitter, boosts in Mastodon) will be discarded and not returned. Also add a corresponding shares query param to the REST API.
• RSS:
  • Add support for RSS input via new rss.to_activities function.
• Instagram (scraping):
  • Handle media items with no user object, add new fetch for comments.
  • Add Instagram.merge_scraped_comments().
• ActivityStreams 2:
  • Handle error when type isn't a string.
• Reddit:
  • Implement get_activities() to fetch posts by the current user or a user specified with user_id.
• Facebook scraping:
  • Skip "Suggested for you" posts.
  • Add log_html kwarg to get_activities; defaults to False.
  • Miscellaneous bug fixes.
• JSONFeed:
  • Handle malformed items.author element.

Notable changes

• Source.original_post_discovery: add new include_reserved_hosts kwarg, defaults to True.
• Facebook:
  • Scraping: handle pictures, videos, link attachments, and text links in timeline/news feed posts.
• Mastodon:
  • Bug fix for get_activities() with fetch_mentions=True: handle notifications with status: null. Maybe happens when a status is deleted?
  • create/preview_create: support bookmarks. (Nothing special happens with them; their content is posted as a normal toot.)
• microformats2:
  • Stop rendering image.displayName as visible text in HTML, since it's already in the <img>'s alt attribute.
  • Add bookmark-of support.
  • Add prefix_image_urls() function.
  • Handle null content in AS1/2 objects.
  • json_to_object bug fix for composite bookmark-of properties.
• Twitter:
  • create/preview: support large videos via async upload. We now pass media_category=tweet_video to the chunked upload INIT stage, and then make blocking STATUS calls until the video is finished processing. (bridgy#1043)
  • create/preview: allow bookmarks. (bridgy#1045)
  • create/preview: allow non-Twitter replies, ie activities that include inReplyTo URLs even if none of them point to a tweet. (bridgy#1063)
  • get_activities: support list ids as well as slugs.
  • Bug fixes for removing t.co links to quoted tweets.
  • Bug fix for multiple instances of the same link in tweet text.
  • get_activities(): raise ValueError on invalid user_id.
• REST API: ported web framework from webapp2 to Flask. No user-visible behavior change expected.
