slack-go/slack v0.32.0

on GitHub

This release expands Slack Code support with channel views, context bars, and canvas collaboration, and fixes permission diagnostics, slash-command decoding, and workflow-button validation.

Breaking changes

• Update interfaces, mocks, and function values that use the old canvas creation
  signatures. CreateCanvas and CreateCanvasContext now accept
  options ...CreateCanvasOption. Existing direct calls still compile, but these
  methods no longer satisfy interfaces with the old fixed signatures. Add the
  variadic parameter to interface and mock declarations; adapt stored function
  values or wrap the call in a function with the old signature.
• Use field names when initializing Properties, SlackResponse,
  KickUserFromConversationSlackResponse, or SlackErrorResponse. New fields
  make positional literals fail to compile. Existing keyed literals still work.

Added

• Show code diffs, HTML reports, Block Kit interfaces, and canvases in Slack Code
  channels. Use SetAgentConversationView to publish or update a view,
  ListAgentConversationViews to discover attached views, and
  RemoveAgentConversationView to remove them. All have Context variants.
  Slack documents pull-request views too, but live requests have returned
  invalid_view_type; publish a unified diff with AgentViewTypeDiff if that
  happens.
• Give a code channel useful context. Set context-bar links, action items,
  a summary message, and external resource details with
  SetAgentConversationProperties or its Context variant. Read session status,
  title, assigned agents, origin message, context-bar ownership, summary, and
  managed views through Properties.AgentSession and Properties.CodeChannel
  in conversation responses.
• Read and revise canvases attached to code channels.
  GetAgentConversationCanvas retrieves markdown and comment threads, including
  replies and optional resolved threads. SetAgentConversationCanvasContent
  replaces the markdown while preserving section IDs and comment anchors on
  unchanged sections. Both have Context variants.
• Create a canvas directly in a channel, including in free workspaces that
  require a channel. Pass CreateCanvasOptionChannelID(channelID) to
  CreateCanvas or CreateCanvasContext (#1623).
• Try the new examples/slack_code CLI for channel
  setup, context bars, views, canvases, commands, metadata inspection, and archival.
  It includes sample HTML, Block Kit, markdown, and unified-diff files.

Fixed

• See which scopes are missing when an API call fails. Slack's needed and
  provided values are now preserved in responses and SlackErrorResponse, even
  for methods that return only an error. Use errors.As to inspect Needed and
  Provided; the error text is unchanged.
• Discover code-channel views even when Slack returns an empty legacy views
  array. ListAgentConversationViews also preserves session_views, including
  view types, names, and owner IDs.
• Receive slash commands when Slack omits is_enterprise_install. JSON
  decoding now accepts absent or null values, including observed Slack Code
  context-bar action deliveries over Socket Mode.
• Send workflow buttons without an action ID. An empty
  WorkflowButtonBlockElement.ActionID is omitted from JSON so the button passes
  Slack's block validation. Populated IDs are preserved.

Documentation and testing

• Clarify that Slack documents raw_number table cells for publishing. If a
  workspace rejects them with invalid_blocks, send the number as a
  TableRawTextCell. Null cells remain a received-only representation.
• Add regression coverage for code-channel lifecycle events, Block Kit view
  interactions, and agent slash commands through the existing HTTP and Socket
  Mode parsers and handlers.
