* Tighten up `datetime` conversion to match the [ATProto recommended format](https://atproto.com/specs/lexicon#datetime).

* `jsonfeed`:
* Switch from `white-space: pre` CSS to converting newlines to `<br>`s because some feed readers follow it strictly and don't even line wrap ([456](https://github.com/snarfed/granary/issues/456)).
* `mastodon`:
* Add compatibility support for [Truth Social](https://truthsocial.com/).
* Handle truncated JSON API responses.
* `microformats2`:
* `json_to_object`: drop backward compatibility support for `like` and `repost` properties. [Background discussion.](https://chat.indieweb.org/dev/2022-12-23#t1671833687984200)
* `json_to_object`: add new `rel_urls` kwarg to allow attaching `displayName`s to `urls` based on HTML text or `title` attribute ([bridgy-fed331](https://github.com/snarfed/bridgy-fed/issues/331)).

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.
* Twitter, Mastodon, Flickr, GitHub:
* `create`/`preview`: support the AS1 `favorite` verb as well as `like`. ([bridgy1345](https://github.com/snarfed/bridgy/issues/1345))
* Atom:
* Switch to converting AS1 `id` (instead of `url`) to Atom `id`.
* Reddit:
* Implement `get_actor`.
* Mastodon:
* `create`/`preview`: allow non-Mastodon replies, ie activities that include `inReplyTo` URLs even if none of them point to a toot. ([bridgy1321](https://github.com/snarfed/bridgy/issues/1321))
* Raise `requests.HTTPError` with `response.status_code` 502 instead of `JSONDecodeError` on non-JSON responses. This is synthetic, but more helpful for error handling.
* microformats2:
* `object_to_json` and related functions: handle all escaped HTML entities, not just `&amp;` `&lt;` `&gt;`.
* Unify `microformats2.prefix_image_urls` and `prefix_video_urls` into a new `as1.prefix_urls` function.
* RSS:
* Remove `itunes:category`. It has to be [one of Apple's explicit categories](https://feedgen.kiesow.be/ext/api.ext.podcast.html#feedgen.ext.podcast.PodcastExtension.itunes_category), which we aren't prepared to validate, so don't try.
* 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

* ActivityStreams 2:
* Fix spec compliance bug: [`icon` and `image` are singly valued, not multiply valued](https://www.w3.org/TR/activitystreams-vocabulary/#dfn-icon).
* 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.
* Propagate `url` values into new `PropertyValue` attachments on `Person` objects; these end up in Mastodon's "profile metadata" link fields.
* `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
* Facebook
* 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-atom27](https://github.com/snarfed/facebook-atom/issues/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](https://github.com/snarfed/bridgy/issues/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`.
* Convert `p-note` to AS1 `summary`.
* Bug fixes for converting `image` attachments to `photo`.
* `Source.original_post_discovery`: add new `max_redirect_fetches` keyword arg.

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`](https://indieweb.org/bookmark#How_to_markup) 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](https://twittercommunity.com/t/large-file-can-not-be-finalized-synchronously/82929/3) 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](https://github.com/snarfed/bridgy/issues/1043))
* `create`/`preview`: allow bookmarks. ([bridgy1045](https://github.com/snarfed/bridgy/issues/1045))
* `create`/`preview`: allow non-Twitter replies, ie activities that include `inReplyTo` URLs even if none of them point to a tweet. ([bridgy1063](https://github.com/snarfed/bridgy/issues/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.
