Deprecations

Continuing with the deprecations started in 0.12.1, many more methods and fields have been deprecated in order to make an easier upgrade path to 0.13.

These deprecation messages include a migration path, it is recommended to go one by one using cargo check and migrate each warning to reduce the burden migrating to 0.13. Following is a list of the deprecation PRs and the justification for these changes.

• (#2791) The Channel::is_nsfw method was wrong, useless, and served better by GuildChannel::nsfw
• (#2794) These cache methods needed arcane borrow checker dances internally, and obscure the simplicity of the cache.
• (#2816) Member::highest_role_info is now strictly less powerful than the new Guild::member_highest_role and can avoid a cache lookup if used correctly.
• (#2825)
• • Guild::is_large is less accurate than Guild::large
• • Message::is_own is super simple to implement yourself
• • Message::is_private simply checks if Message::guild_id is none.
• (#2838) Event::PresencesReplace does not exist, and is a relic from when serenity supported user accounts.
• (#2861) TeamMember::permissions is always ["*"], so is useless.

Other notable changes

• (#2790) Added CreateMessage::enforce_nonce, to prevent sending duplicate messages.
• (#2801) Added EditProfile::banner, allowing banners to be set for bots.
• (#2810) Added ChannelId::get_thread_member.
• (#2812) Added Guild::partial_member_permissions_in, which can be used to avoid fetching a Member in message events just to check permissions.
• (#2819) Added From<User> for CreateEmbedAuthor, setting the author name and icon to the User's info.
• (#2813) Added UserId::direct_message, so you don't need a full User to direct message.
• (#2834) Added Http::default_allowed_mentions to set the AllowedMentions to be used with every request.
• (#2830) Added Guild(Id)::bulk_ban, allowing bulk banning without hitting rate limits.
• (#2836) Added support for Message Polls, including reading and sending them.
• (#2807) Added support for User Apps, alllowing user-installable application commands.
• (#2882) Added support for super reactions.
• Many documentation fixes and other optimisations to improve memory and CPU usage.
