PRAW follows semantic versioning.

Added

• :meth:`~.SubredditLinkFlairTemplates.reorder` to reorder a subreddit's link flair templates.
• :meth:`~.SubredditRedditorFlairTemplates.reorder` to reorder a subreddit's redditor flair templates.
• :func:`.stream_generator` now accepts the continue_after_id parameter, which starts the stream after a given item ID.
• Support for new share URL format created from Reddit's mobile apps.

Fixed

• An issue where submitting a post with media would fail due to an API change.

Changed

• Drop support for Python 3.7, which is end-of-life on 2023-06-27.

Fixed

• An issue with replying to a modmail conversation results in a error.

Added

• :meth:`.delete_mobile_banner` to delete mobile banners.

• :meth:`.upload_mobile_banner` to upload mobile banners.

• Experimental :meth:`~.Submission._edit_experimental` for adding new inline media or editing a submission that has inline media.

  !DANGER!

  This method is experimental. It is reliant on undocumented API endpoints and may result in existing inline media not displaying correctly and/or creating a malformed body. Use at your own risk. This method may be removed in the future without warning.

  This method is identical to :meth:`.Submission.edit` except for the following:

  • The ability to add inline media to existing posts.
  • Additional preserve_inline_media keyword argument to allow PRAW to attempt to preserve the existing inline media when editing a post. This is an experimental fix for an issue that occurs when editing a post with inline media would cause the media to lose their inline appearance.

Fixed

• An issue with iterating :class:`.ModNote` when a user has more than a hundred notes.
• Removal reasons are now returned in the same order as they appear on Reddit.

Changed

• Revert :meth:`~.Comment.edit` positional argument deprecation.

Added

• :meth:`.me` will no longer return None when called in :attr:`.read_only` mode starting in PRAW 8. A :py:class:`DeprecationWarning` will be issued. To switch forward to the PRAW 8 behavior set praw8_raise_exception_on_me=True in your :class:`.Reddit` call.

Fixed

• Asynchronous check will no longer fail in Python 3.6 multithreading edge cases.

Changed

Fixed

• An issue where certain subreddit settings could not be set through :meth:`.SubredditModeration.update`, such as welcome_message_enabled and welcome_message_text. This change also removes the need for PRAW to track current subreddit settings and send unmodified ones in the update request.

• :meth:`~.Subreddit.submit_image` and :meth:`~.Subreddit.submit_video` will throw :class:`.MediaPostFailed` when Reddit fails to post an image or video post.

• Methods :meth:`.SubredditLinkFlairTemplates.update` and :meth:`.SubredditRedditorFlairTemplates.update` contain a new parameter, fetch, that toggles the automatic fetching of existing data from Reddit. It is set to True by default.
• Values in methods :meth:`.SubredditLinkFlairTemplates.update` and :meth:`.SubredditRedditorFlairTemplates.update` that are left as the defaults will no longer be over-written if the fetch parameter is set to True, but will fill in existing values for the flair template.

This attribute will be functionally useless once Reddit implements their change.

• Instances of :class:`.Trophy` can be compared for equality with each other.
• :class:`.Reddit` has a new configurable parameter, timeout. This defaults to 16 seconds. It controls how long PRAW will wait for a response before throwing an exception.

• Calling :meth:`~.Comment.refresh` previously could have resulted in a AttributeError: "MoreComments" object has no attribute "_replies" exception. This situation will now result in a :class:`.ClientException`.

Removed

• Iterating directly over :class:`.SubredditRelationship` (e.g., subreddit.banned, subreddit.contributor, subreddit.moderator, etc) and :class:`.SubredditFlair` is no longer possible. Iterate instead over their callables, e.g. subreddit.banned() and subreddit.flair().
• The following methods are removed: Subreddit.mod.approve, Subreddit.mod.distinguish, Subreddit.mod.ignore_reports, Subreddit.mod.remove, Subreddit.mod.undistinguish, Subreddit.mod.unignore_reports.
