------------------

**Fixed**

  exists on Python 3.7+.

7.1.1 (2021/02/02)
------------------

**Added**

- Add method :meth:`~.Subreddits.premium` to reflect the naming change in Reddit's API.

  :meth:`.Reddit.info`.
- A check to see if PRAW is running in an asynchronous environment and will advise the
  user to use `Async PRAW <https://asyncpraw.readthedocs.io>`_. This also adds a
  configuration option to disable the check.

**Changed**

- Drop support for Python 3.5, which is end-of-life on 2020-09-13.
- :class:`~.BoundedSet` will now utilize a Last-Recently-Used (LRU) storing mechanism,
  which will change the order in which elements are removed from the set.
- Improved :meth:`~.Subreddit.submit_image` and :meth:`~.Subreddit.submit_video`
  performance in slow network environments by removing a race condition when

**Fixed**

- An issue where leaving as a moderator fails if you are using token auth.

  in every case.

------------------

**Added**

- :class:`.Rule` to represent one rule of a subreddit.
- :class:`.SubredditRules` to get and add rules.

  PRAW 8.0.

**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.
- Instances of ``BadRequest``\ s captured by PRAW that do not contain any detailed JSON
  data are re-raised as the original ``BadRequest``.
- :meth:`~.Subreddit.submit_image` and :meth:`~.Subreddit.submit_video` will throw

------------------

**Added**

- ``config_interpolation`` parameter for :class:`.Reddit` supporting basic and extended
  modes.
- Add :meth:`.Redditors.partial_redditors` that returns lightweight redditor objects
  that contain only a few fields. This is useful for resolving Redditor IDs to their
  usernames in bulk.
- :meth:`.User.friends` has a new parameter ``user`` that takes either an instance of
  :class:`.Redditor` or a string containing a redditor name and returns an instance of
  :class:`.Redditor` if the authenticated user is friends with the user, otherwise
  throws an exception.
- :meth:`.SubmissionModeration.flair` has the parameter ``flair_template_id`` for
  applying flairs with template IDs.
- :meth:`~.Emoji.update` supports modifying an emoji's permissions.
- :meth:`~.SubredditEmoji.add` now supports optionally passing booleans to set an
  emoji's permissions upon upload.
- 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.
- The parameter ``text`` for methods :meth:`.SubredditLinkFlairTemplates.update` and
  :meth:`.SubredditRedditorFlairTemplates.update` is no longer required.
- There is a new method, :meth:`.Subreddit.post_requirements`, to fetch a subreddit's
  post requirements.
- Method :meth:`.SubmissionModeration.sticky` will now ignore the Conflict exception
  generated by trying to sticky the same post multiple times.
- A new method :meth:`.CommentModeration.show` will uncollapse a comment that was
  collapsed because of Crowd Control
- Methods :meth:`.Subreddit.submit_image` and :meth:`.Subreddit.submit_video` will throw
  :class:`.TooLargeMediaException` if the submitted media is rejected by Reddit due to
  the size of the media.
- Class :class:`.Reddit` has an attribute, ``validate_on_submit``, that can be set after
  class initialization that causes methods :meth:`.Subreddit.submit`,
  :meth:`.Subreddit.submit_image`, :meth:`.Subreddit.submit_video`, and
  :meth:`.Submission.edit` to check that the submission matches a subreddit's post
  validation rules. This attribute will be functionally useless once Reddit implements
  their change. This attribute will be deprecated on the next release after Reddit's
  change, and will be removed on the next major release after Reddit's change.

.. warning::

    In May-June 2020, Reddit will force all submissions to run through a subreddit's
    validation rules.

- Introduced a data class, :class:`.RedditErrorItem`, to represent an individual error
  item returned from Reddit.
- Class :class:`.RedditAPIException` now serves as a container for the
  :class:`.RedditErrorItem`\ s. You can access the items by doing
  ``RedditAPIException.items``, which returns a list.
- :class:`.APIException` is an alias to :class:`.RedditAPIException`.
- Parameter ``discussion_type`` to methods :meth:`.Subreddit.submit`,
  :meth:`.Subreddit.submit_image`, and :meth:`.Subreddit.submit_video` to support
  submitting as a live discussion (set to ``CHAT``).
- 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.
- PRAW now handles ratelimit errors returned as instances of
  :class:`.RedditAPIException`.
- :class:`.Reddit` has one new parameter, ``ratelimit_seconds`` . The parameter
  configures the maximum amount of seconds to catch ratelimits for. It defaults to 5
  seconds when not specified.

**Changed**

- ``prawcore.BadRequest`` should no longer be raised. Instead a more useful
  :class:`.RedditAPIException` instance will be raised.
- Set the default comment sort to ``confidence`` instead of ``best`` because it turns
  out ``best`` isn't actually the correct value for the parameter.

**Deprecated**

- :class:`.APIException` is deprecated and slated for removal in PRAW 8.0.

**Fixed**

- :meth:`.SubredditFlair.update` will not error out when the flair text contains quote
  marks.

**Removed**

- Converting :class:`.APIException` to string will no longer escape unicode characters.

  ``praw.models.mod_action``, or directly import ``ModAction`` from ``praw.models``.
- Methods :meth:`.SubredditLinkFlairTemplates.update` and
  :meth:`.SubredditRedditorFlairTemplates.update` will no longer create flairs that are
  using an invalid template id, but instead throw a :class:`.InvalidFlairTemplateID`.
- Method ``reddit.user.moderator_subreddits`` has been removed. Please use
  :meth:`.Redditor.moderated` instead.

  infinite loop when ``"before"`` parameter is provided.

5.3.0 (2017/12/16)
------------------

**Added**

- :meth:`.Redditor.block`

  when encountering a HTTP 451 response.

5.2.0 (2017/10/24)
------------------

**Changed**

- An attribute on :class:`.LiveUpdate` now works as lazy attribute (i.e. populate an
  attribute when the attribute is first accessed).

**Deprecated**

- ``subreddit.comments.gilded`` because there isn't actually an endpoint that returns
  only gilded comments. Use ``subreddit.gilded`` instead.

**Fixed**

- Removed ``comment.permalink()`` because ``comment.permalink`` is now an attribute
  returned by Reddit.

5.1.0 (2017/08/31)
------------------

**Added**

- :meth:`.Submission.crosspost` to crosspost to a subreddit.

**Fixed**

- Calling :meth:`~.Comment.refresh` on a directly fetched, deeply nested
  :class:`.Comment` will additionally pull in as many parent comments as possible
  (currently 8) enabling significantly quicker traversal to the top-most
  :class:`.Comment` via successive :meth:`.parent()` calls.
- 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`.
- Properly handle ``BAD_CSS_NAME`` errors when uploading stylesheet images with invalid
  filenames. Previously an ``AssertionError`` was raised.
- :class:`.Submission`'s ``gilded`` attribute properly returns the expected value from
  reddit.

5.0.1 (2017/07/11)
------------------

**Fixed**

- Calls to :meth:`.hide()` and :meth:`.unhide()` properly batch into requests of 50
  submissions at a time.
- Lowered the average maximum delay between inactive stream checks by 4x to 16 seconds.

**Added**

- :meth:`.Subreddit.submit` accepts a flair template ID and text.

**Fixed**

**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``,

  :meth:`.Redditor.message`, :meth:`.Subreddit.message`, :meth:`.select`, and
  :meth:`.unfriend` are removed as they do not provide any useful information.
- ``praw.ini`` no longer reads in ``http_proxy`` and ``https_proxy`` settings.
- ``is_link`` parameter of :meth:`.SubredditRedditorFlairTemplates.add` and
  :meth:`.SubredditRedditorFlairTemplates.clear`. Use
  :class:`.SubredditLinkFlairTemplates` instead.

4.6.0 (2017/07/04)
------------------

The release's sole purpose is to announce the deprecation of the ``is_link`` parameter
as described below:

**Deprecated**

- ``is_link`` parameter of :meth:`.SubredditRedditorFlairTemplates.add` and

**Changed**

- :meth:`~.Subreddit.submit` accepts ``selftext=''`` to create a title-only submission.

  children have been added to the :class:`.CommentForest` enabling callers of

  ``Subreddit.mod.undistinguish``, ``Subreddit.mod.unignore_reports``.
- Support for passing a :class:`.Submission` to :meth:`.SubredditFlair.set` will be
  removed in PRAW 5. Use :meth:`.Submission.flair` instead.

  and will be removed in PRAW 5.

- Fix bug where Comment replies becomes ``[]`` after attempting to access an invalid
