Latest from the changelog

Jul 13, 2020

Previously, when a user mentioned an app that wasn't party to the conversation, the user could Invite the app to the conversation, Let Them Know, or Do Nothing. The Let Them Know button didn't work. We've fixed that mistake by removing the button, and updated our documentation on the app_mention event as well.

Jul 9, 2020

Mark messages unread for users with conversations.mark. Bespoke clients and personal utilities should use this method sparingly.

Jul 9, 2020

The URL where users manage existing installations of Slack apps is changing to https://app.slack.com/apps-manage/. You might not even notice the difference, but we’re letting you know just in case.
