+### 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](https://github.com/serenity-rs/serenity/pull/2791)) The `Channel::is_nsfw` method was wrong, useless, and served better by `GuildChannel::nsfw`
+- ([#2794](https://github.com/serenity-rs/serenity/pull/2794)) These cache methods needed arcane borrow checker dances internally, and obscure the simplicity of the cache.
+- ([#2816](https://github.com/serenity-rs/serenity/pull/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](https://github.com/serenity-rs/serenity/pull/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](https://github.com/serenity-rs/serenity/pull/2838)) `Event::PresencesReplace` does not exist, and is a relic from when serenity supported user accounts.
+- ([#2861](https://github.com/serenity-rs/serenity/pull/2861)) `TeamMember::permissions` is always `["*"]`, so is useless.
+
+### Other notable changes
+- ([#2790](https://github.com/serenity-rs/serenity/pull/2790])) Added `CreateMessage::enforce_nonce`, to prevent sending duplicate messages.
+- ([#2801](https://github.com/serenity-rs/serenity/pull/2801)) Added `EditProfile::banner`, allowing banners to be set for bots.
+- ([#2810](https://github.com/serenity-rs/serenity/pull/2810)) Added `ChannelId::get_thread_member`.
+- ([#2812](https://github.com/serenity-rs/serenity/pull/2812)) Added `Guild::partial_member_permissions_in`, which can be used to avoid fetching a `Member` in message events just to check permissions.
+- ([#2819](https://github.com/serenity-rs/serenity/pull/2819)) Added `From<User>` for `CreateEmbedAuthor`, setting the author name and icon to the `User`'s info.
+- ([#2813](https://github.com/serenity-rs/serenity/pull/2813)) Added `UserId::direct_message`, so you don't need a full `User` to direct message.
+- ([#2834](https://github.com/serenity-rs/serenity/pull/2834)) Added `Http::default_allowed_mentions` to set the `AllowedMentions` to be used with every request.
+- ([#2830](https://github.com/serenity-rs/serenity/pull/2830)) Added `Guild`(`Id`)`::bulk_ban`, allowing bulk banning without hitting rate limits.
+- ([#2836](https://github.com/serenity-rs/serenity/pull/2836)) Added support for **Message Polls**, including reading and sending them.
+- ([#2807](https://github.com/serenity-rs/serenity/pull/2807)) Added support for **User Apps**, alllowing user-installable application commands.
+- Many documentation fixes and other optimisations to improve memory and CPU usage.
