Slack desktop client notifications now pull text from blocks first, falling back to the top-level text field only if no text can be extracted from blocks. Mobile notifications continue to exclusively use message.text.
Agent apps can now receive context about what a user is currently viewing when they send a message. When a user has a channel, DM, thread, canvas, or list open and messages your app, Slack will pass that context automatically.
* We've added a public, read-only ts property to ChatStream and AsyncChatStream, enabling users to call the chat.update API method as a fallback when the server closes a stream due to undocumented timeouts.
Version 4.4.0 of the Slack CLI is here!
Agents now support a new messaging experience, set by your app manifest:

We are excited to announce support for Proof Key for Code Exchange (PKCE). PKCE is an OAuth security extension that enables developers to build more secure Slack applications on public clients, such as desktop apps and mobile apps, without the need to embed a vulnerable client_secret.
