The Kook.Net package now references the Kook.Net.Webhook package and has removed the reference to the Kook.Net.CardMarkup package. If you need to continue using the functionality for building card messages via markup language, please reference the Kook.Net.CardMarkup package separately.

Voice connection and streaming features have been changed to be implemented by an officially supported method. The newly added API for receiving voice data streams is experimental and not officially supported.

The exception thrown by Emote.Parse when an error occurs has been changed from ArgumentException to FormatException. The return result of Emote.ToString has been changed to be equivalent to the result of ToKMarkdownString. The link format provided by MessageExtensions.GetJumpUrl has been adjusted. SocketGuild.ValidBoostSubscriptions has been changed to SocketGuild.ActiveBoostSubscriptions. Tag<T> has been changed to Tag<TKey, TValue>.

Added

• Added support for custom message queues, with the default implementation being synchronous message processing. Support for setting the message queue provider by installing extension NuGet packages and configuring KookSocketConfig.MessageQueueProvider. Kook.Net.MessageQueue.InMemory is the in-memory queue support package, and Kook.Net.MessageQueue.MassTransit is the MassTransit queue support package. Refer to the examples for usage.
• Added support for Webhook mode, which is currently implemented based on the Socket implementation. The Webhook integrated by Kook.Net is the abstract class KookWebhookClient. Kook.Net.Webhook.HttpListener is the Webhook implementation package for HTTP Listener, and Kook.Net.Webhook.AspNet is the Webhook implementation package integrated with ASP.NET. Refer to the examples for usage.

Full Changelog: v0.8.0...v0.9.0

v0.8.0

Update Roadmap

Due to changes in the KOOK API, Bot users can no longer obtain all the necessary basic guild information at startup through the /guild/index API. Instead, it is now required to traverse each guild via the /guild/view API. This change can result in a significantly longer startup time and a large number of API requests for Bots that have joined many guilds. Therefore, the current version introduces the KookSocketConfig.StartupCacheFetchMode configuration item, which defines how the Bot loads the basic guild data needed at startup.

• Synchronous: In synchronous mode, after obtaining a simple list of guilds at client startup, the client fetches the basic data of each guild through the API before triggering the Ready event.
• Asynchronous: In asynchronous mode, after obtaining a simple list of guilds at client startup, the Ready event is triggered immediately, and a background task is started to fetch all the basic guild data.
• Lazy: In lazy mode, after obtaining a simple list of guilds at client startup, the Ready event is triggered immediately without proactively fetching the basic guild data. When events involving the guild are received from the gateway, the guild's basic data will be fetched through the API if it has not already been obtained.
• Auto: In automatic mode, the default setting, the client's startup mode is automatically determined based on the number of guilds the Bot has joined. If the number of guilds reaches LargeNumberOfGuildsThreshold (default is 50), it will be Lazy; if it reaches SmallNumberOfGuildsThreshold (default is 5), it will be Asynchronous; otherwise, it will be Synchronous. This determination is made each time the Bot connects to the WebSocket.

When not using Synchronous mode, after the Ready event, accessing cached guild entities might result in entities that do not fully contain basic guild data. The IsAvailable property indicates whether the guild entity has fully cached basic data through the API. In such cases, please proactively call the UpdateAsync method to update the cached guild entity through the API. The basic guild data mentioned above mainly includes the guild's channels, roles, channel permission overrides, and the current user's nickname within guilds.

The entire framework code has been updated to support nullable reference static analysis diagnostics. For the concept of nullable reference types in C#, please refer to Nullable reference types - C# | Microsoft Learn. After updating to the current version, all values that may be null will be marked as nullable types. This may cause some code to generate warnings during compilation, which should be treated as potential null reference exceptions and fixed accordingly.

Additionally, IQuote has a new implementation MessageReference, which only contains the ID of the message to be referenced and is used when calling the API in user code. Existing user code that creates Quote should migrate to MessageReference as soon as possible.

fileName has been renamed to filename; the event parameter Cacheable<SocketMessage, Guid> has been changed to Cacheable<IMessage, Guid>; SectionAccessoryMode.Unspecified is now replaced by null; Format.StripMarkDown has been renamed to StripMarkdown; and the filename parameter in the SendFileAsync overload that accepts the Stream type is now mandatory. Please note that these changes may cause compilation errors and should be fixed accordingly.

Additions

• KookSocketConfig adds the StartupCacheFetchMode, LargeNumberOfGuildsThreshold, and SmallNumberOfGuildsThreshold configuration items to customize how the Bot's Socket client fetches the basic guild data needed at startup via the API.
• Two new configuration properties AutoUpdateRolePositions and AutoUpdateChannelPositions have been added to KookSocketConfig, defaulting to false. When enabled, the client will automatically fetch data via the API upon receiving related events to maintain the cached role and channel sorting information.
• Embed adds CardEmbed.
• Card entities and builders now implement IEquatable<T>.
• SocketSelfUser now implements IUpdateable.
• Added IGuild.RecommendInfo.Certifications.
• IQuote has a new implementation MessageReference, which only contains the ID of the message to be referenced and is used when calling the API in user code.
• Support for the event types embeds_append, sort_channel, updated_server_type, batch_added_channel, batch_updated_channel, batch_deleted_channel, live_status_changed, PERSON typed updated_guild, add_guild_mute, delete_guild_mute, unread_count_changed has been added, but it is not yet confirmed whether these events will actually be dispatched.

Fixes

• Fixed the issue where the author of private messages was incorrect.
• Fixed the issue where SocketUserMessage.Quote.Author could be null.
• Fixed the issue where Tags were missing corresponding values when referencing nonexistent entities in messages.
• Fixed the issue where the voice client failed to handle undefined events, causing stream crashes.
• Fixed the issue where parsing newly introduced mixed media messages failed.
• Corrected the behavior of updating user nicknames.

Changes

• Enabled nullable reference types feature. For the concept of nullable reference types in C#, please refer to Nullable reference types - C# | Microsoft Learn.
• Various validations for the card builder are now deferred to the Build call.
• The types of properties involving lists in cards have been changed to IList<T>.
• Quote.Empty and its public constructor have been marked as Obsolete, and MessageReference should be used instead.
• fileName has been renamed to filename.
• The filename parameter in the SendFileAsync overload that accepts the Stream type is now mandatory.
• BaseSocketClient._baseConfig has been renamed to BaseConfig.
• The event parameter Cacheable<SocketMessage, Guid> has been changed to Cacheable<IMessage, Guid> to address the issue of entity download failure.
• SectionAccessoryMode.Unspecified has been removed; please use null instead.
• Format.StripMarkDown has been renamed to StripMarkdown, and the original method has been marked as Obsolete.
• Format.StripMarkdown now removes hyphens -.

Others

• Added a reference to PolySharp on .NET 7 and earlier target frameworks to support the implementation of some new features on older frameworks.
• Added integration tests for some Socket events.

Full Changelog: v0.7.0...v0.8.0

v0.7.0

Update Path

The KOOK client now supports sending messages within voice channels. As a result, the following APIs have been modified:

• CreateVoiceChannelProperties now inherits from CreateTextChannelProperties.
• ModifyVoiceChannelProperties now inherits from ModifyTextChannelProperties.
• IVoiceChannel now inherits from ITextChannel.
• The value of ChannelPermissions.Voice now includes permissions for text channels.
• The SocketTextChannel.GetMessagesAsync series of methods are now virtual methods, to be overridden by SocketVoiceChannel.

It's important to note that, due to limitations in the KOOK API, fetching message history and pinning messages are not supported within voice channels via the API. Therefore, calling GetMessagesAsync and GetPinnedMessagesAsync methods from IMessageChannel on voice channels is not supported.

Additionally, while voice channels support operations on Topic and SlowModeInterval at the API level, the KOOK client currently does not reflect these capabilities.

Creating channels does not immediately support specifying a Topic. The Topic property in CreateTextChannelProperties has been removed and does not take effect. Please use the ITextChannel.ModifyAsync method to modify the channel after creation.

Added

• Added support for defining card messages via XML. (#9 by @LiamSho)
• IVoiceChannel now inherits from ITextChannel, with relevant implementations updated.
• Added SentRequest event to BaseKookClient.
• Added non-null result prompts for parsing card message-related Try* methods.

Fixed

• Corrected the issue with ConnectionManager incorrectly updating State when Disconnected.

Changes

• Removed the Topic property from CreateTextChannelProperties.

Misc

• Marked the project as not supporting AOT and assembly trimming.
• Added example project Kook.Net.Samples.CardMarkup. (#9 by @LiamSho)
• Added documentation for defining card messages via XML. (#9 by @LiamSho)
• Added Logo.

New Contributors

• @LiamSho made their first contribution in #9

Full Changelog: v0.6.0...v0.7.0
