Changelog

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

[0.27.0]

Added

• Block Kit: Add support for data_visualization block through DataVisualizationBlock.
• Interaction payloads: Team now preserves enterprise_id and enterprise_name when Slack includes Enterprise org details in interaction payload team objects.

[0.26.0]

Added

• slackevents: EventsAPIEvent now unmarshals the is_ext_shared_channel field, and ParseEvent propagates it for callback events (#1564 and #1565).
• Block Kit: HeaderBlock now supports the optional level field (1-4, mapping to H1-H4 heading levels), with a HeaderBlockOptionLevel builder (#1563).
• Block Kit: CardBlock now supports the slack_icon field via the new SlackIconObject composition object (with a NewSlackIconObject constructor and WithSlackIcon builder) and the subtext field (with a WithSubtext builder). slack_icon is mutually exclusive with icon (#1562).

[0.25.0]

Changed

Added

• Block Kit: DataTableBlock for the data_table block, with NewDataTableBlock, AddRow, raw-text/raw-number/rich-text cell constructors, and WithPageSize / WithRowHeaderColumnIndex builders.

Changed

• NewTaskCardBlock and NewPlanBlock nil-guard their variadic options, matching the other block constructors (#1236).

[0.23.1] - 2026-05-10

Fixed

• NewSecretsVerifier now rejects empty signing secrets to avoid accepting forged request
