Changelog

Sourced from github.com/slack-go/slack's changelog.

[0.29.0] - 2026-08-15

Fixed

• slackevents: AppMentionEvent and MessageEvent now expose the Data Access API action token through a new ActionToken field, which reads action_token from the event object itself. Slack sends the token there on app_mention and message events, but both types only modelled it nested inside assistant_thread, so the token was silently dropped and bot-token calls to assistant.search.context failed with invalid_action_token. The existing AssistantThread field is unchanged (#1577, #1580).

[0.28.0] - 2026-08-15

Added

• Block Kit: Add support for container block through ContainerBlock, with a NewContainerBlock constructor, fluent With* builders (WithTitle, WithRichTextTitle, WithSubtitle, WithIcon, WithWidth, WithCollapsible, WithHeaderDivider, WithBlockID), an AddChildBlock helper and a Validate method (#1574).
• PostMessageWithResponse and PostMessageWithResponseContext return the full Message object from the chat.postMessage response alongside the channel and timestamp, giving access to response-only fields such as Message.ThreadTimestamp (#1572).
• CompleteUploadExternalParameters and UploadFileParameters now take Channels, which shares a single uploaded file with up to 100 conversations in one files.completeUploadExternal request (#1579).
