Slack for Mac 3.0

Slack has released version 3.0 of its Mac desktop client, a substantial release for the group messaging system and collaboration tool that uses less memory and starts up faster, particularly when you have a lot of workspaces. The app now flips between workspaces more quickly, badges workspaces you aren’t signed in to, improves the speed of reloading during drag-and-drop operations, moves the sidebar out of the way when viewing full-screen video, fixes some crashes experienced in macOS 10.13 High Sierra, and ensures that scrolling through messages is flicker-free. (Free from Slack and the Mac App Store, 71 MB, release notes, 10.9+)
