v0.11.3

• Added optional teamId parameter to IConversationsApi.Create.
• Added support for message metadata.
• Added MessageMetadataPosted, MessageMetadataUpdated, and MessageMetadataDeleted events.
• Added BotId, AppId, and BotProfile properties to MessageEvent.
• Added TeamId, Deleted, and Updated properties to BotInfo.
• Added RichTextInput and fixed posting messages with RichTextBlocks.

Metadata

When posting a message to Slack, you can specify the metadata in one of two ways:

await slack.Chat.PostMessage(new Message
    {
        Channel = "#general",
        Text = "My message",

        // Use your own metadata object. It will be serialized with the standard Slack conventions,
        // and the event_type will be the name of the class in snake case.
        MetadataObject = new MyMetadata("my info"),

        // Specify the metadata JSON explicitly. This will take precedence over MetadataObject.
        MetadataJson = new MessageMetadata
            {
                EventType = "my_metadata",
                EventPayload = JToken.Parse("""{ "custom_info": "my info" }""") // Get your JToken from wherever you like  
            }
    });

Messages retrieved from Slack will have a Metadata property that contains the event type and JSON as a JToken. To deserialize the JSON using the standard Slack JSON conventions, use the ToObject method on MessageMetadata, not the ToObject method on JToken:

var myMetadata = message.Metadata.ToObject<MyMetadata>();

Potentially breaking changes

• If you were passing a CancellationToken to IConversationsApi.Create as a positional argument, you'll need to either add null as the teamId argument, or specify the cancellationToken parameter name.
• Added a SlackJsonSettings parameter to the ChatApi constructor. If you're constructing ChatApi manually, you can pass in Default.JsonSettings(), or your own customized settings.
• Pushed the InitialValue property of TextInput down to its sub-classes, to account for RichTextInput's different type of value.

v0.11.2

• Renamed SnoozeEndTime on SnoozeResponse and OwnDndResponse so it deserializes properly.
• Added SnoozeIsIndefinite to SnoozeResponse and OwnDndResponse.

v0.11.1

• Added missing IsExtSharedChannel property to EventCallback.
• Incoming requests are logged when using SlackNet.AspNetCore.
• Default ASP.NET logger logs with the specific SlackNet category (e.g. SlackNet.Error instead of just SlackNet).

When using the default logger with ASP.NET, individual SlackNet log categories can be enabled in appsettings.json with:

"Logging": {
  "LogLevel": {
    "SlackNet.Data": "Trace",
    "SlackNet.Serialization": "Trace",
    "SlackNet.Internal": "Debug",
    "SlackNet.Request": "Information",
    "SlackNet.Error": "Error"
  }
}

Setting a category to a higher level will filter out logs from that category.

v0.11.0

• Added the UserHuddleChanged, UserProfileChanged, and UserStatusChanged events.
• Added logging for serialization. Useful for debugging serialization issues, but otherwise I'd recommend filtering out LogEvents in the Serialization category.
• Added Attachments property to MessageSearchResult.
• Added Unsafe property to RichTextLink.
• Added ThumbWidth, ThumbHeight, OriginalUrl, ServiceName, and ServiceIcon properties to Attachment.

Breaking Changes

• Removed the stars API and associated classes. See this Slack announcement for more details.
