I’m counting the days until the holidays, how about you?! 🦃⛄ As things start to wind down, I always find I have a bit more mental space (and time!) to tackle those projects that I’ve left on my to-do list. Perhaps now is the best time to finally launch that idea you’ve been simmering on since summer. 🚀
So grab your coziest blanket, settle in with those autumn vibes, and let’s see what we’ve been cooking up. 🍁✨

We’ve introduced a new suite of features to help Slack apps provide an end-user experience typical of LLM tools:Slack apps can now stream in their responses to the end user using three new API methods.
There are new Block Kit components to allow end users to quickly interact with AI responses.
The Node and Python SDKs have new utilities to streamline integration of these new features.
Check out the full changelog post and see how you can integrate these new features into your AI Slack apps!
- Introducing Work Objects
One of the primary ways to share external content within Slack is by posting URL links in conversations. However, links in their primitive form don’t provide a lot of information. That’s why we originally introduced link unfurling, so that Slack apps could provide rich previews and actions inside of conversations without requiring users to click the link. With Work Objects, apps can take the unfurling experience even further.
Work Objects allow you to represent and collaborate on data from third-party services where the work is already happening, right in Slack. To learn how it all comes together to create a seamless experience for your users check out the full documentation.
- Announcing the redesigned Oauth page
Installing with OAuth is a major point of entry for users installing Slack apps. This flow guides users through configuring the various options their apps require to be installed successfully both at the workspace and org level, as well as the permissions their apps need from the workspace or org prior to installation.
The new and improved page replaces the old single-column OAuth experience with a brand new double-column, fully responsive view – making all of the configuration options and permissions details easier to read and understand while stepping through the OAuth flow.
To try out the new experience for yourself, install any app that you like onto your workspace. We hope you like it!
