Release: Slack CLI v4.10.0

October 13, 2026

Version 4.10.0 of the developer tools for the Slack platform has landed! The slack create --app command now automatically syncs the manifest from app settings to your local project. We've made a small change to the output of the sandboxes list command: status and type previously displayed lowercase, and now Type: basic will be displayed for basic sandboxes (previously we only showed the type label for partner sandboxes, to differentiate from developer sandboxes).

Slack Code for developers

October 7, 2026

Slack Code enables even more collaboration between humans and agents in Slack by creating dedicated channels for deeper work. Agents can now create ephemeral channels from existing conversations, providing agents and their human collaborators a shared, visible place to work. Your agents manage the space: create a new code channel when a user’s request entails more work than a quick reply, and add bookmarks and artifacts so users can see your agent’s work. As the work progresses, your agent can post updates and convey status, and even archive the channel when work is complete.

Release: Slack CLI v4.9.0

October 2, 2026

Version 4.9.0 of the Slack CLI is here! We've added support for the settings.app_level_token_rotation_enabled app manifest property, which opts your app in to rotating app-level tokens. We fixed an issue where an expired login with an invalid refresh token caused the CLI to retry token rotation on every command. The CLI now asks you to run slack login again. We fixed an issue where the slack activity --tail and slack run commands kept requesting activity logs after the login token became invalid. The command now exits with the auth error.

Release: Slack CLI v4.8.0

September 15, 2026

Version 4.8.0 of the Slack CLI is here! The CLI falls back to manifest.json when the get-manifest hook is unavailable. We've added the slack manifest sync command to sync the app manifest between project and app settings. We've added a --manifest-source flag to the run and deploy commands. We've added support for the code_channels app manifest feature. We fixed an issue where interactive selection prompts left lingering rendered lines on screen after a selection is made.

Release: Slack CLI v4.7.0

August 31, 2026

Version 4.7.0 of the Slack CLI has been released! We've added the slack app request command, which checks the status of your most recent request to have an app approved for install. We've added support for custom app icons. The slack run and slack deploy commands can now be used to upload an icon file. We've fixed the help template so hidden subcommands are no longer listed under their parent command.

The next wave of Agent messaging experience

August 20, 2026

We're rolling out a wave of updates to agents on Slack, along with an important heads-up about the road ahead for the Assistant messaging experience. Agent updates and the deprecation of assistant_view The Assistant messaging experience (assistant_view) will be deprecated in February 2027. The assistant-related methods that power it are being replaced by a new set of API methods: the Agent Sessions API. Agent sessions let users manage their conversations with your agent in one place, with a status, a title, and a stop button. The agents.sessions.setStatus and agents.sessions.rename API methods replace the assistant.threads.setStatus and assistant.threads.setTitle API methods, respectively. For now, your existing calls keep working through a compatibility bridge. See the Agent sessions guide to get started. The Agent messaging experience (agent_view) is already available, and we recommend moving to it now. If your app still uses assistant_view, follow the migration guide to move to the new experience. Read more in the guide to developing agents. What's new for agents Alongside this announcement, we're releasing a set of improvements to the agent experience: Upgraded Tools tab: a n

Announcing Slack Code

August 20, 2026

An agent can answer a question in a thread, but some tasks become bigger than a single question. A coding agent may need to implement a change, share a prototype, and iterate on it. A research agent may need to gather information and work through decisions with the people involved. This kind of work needs more than a single response. Slack Code is how agents and people work together to build with AI in Slack, creating dedicated channels for more involved work. A channel is created from an existing conversation, context is carried forward, and agents and collaborators have a shared, visible place to work. Within a session, agents can publish artifacts for people to oversee and iterate on: Code diffs, so people can review what changed Block Kit views, for structured interactive experiences HTML previews, for prototypes and generated interfaces Canvases, for longer-form content and collaboration The work becomes multiplayer: teammates can join channels, review work, add context, and help make decisions, all while collaborating in the same session and with the same artifacts. Your agent manages the lifecycle, creating a channel when a task warrants one, sharing updates as the work prog
