• Communicate with your team and organize your conversations by topics, projects, or anything else that matters to your work
• Message or call any person or group within your team
• Share and edit documents and collaborate with the right people all in Slack
• Integrate into your workflow, the tools and services you already use including Google Drive, Salesforce, Dropbox, Asana, Twitter, Zendesk, and more
• Easily search a central knowledge base that automatically indexes and archives your team’s past conversations and files
• Customize your notifications so you stay focused on what matters

What's New

Version 3.37

Bug Fixes
• Fixed: Uploading a large video or image file would fail silently. Now it generally succeeds, and if it doesn’t, has the decency to let you know.
• Fixed: When sharing multiple photos from the Photos app, one or more would silently slip away into the void. We’ve plugged that hole, and they should all now upload as intended.
• Fixed: The buttons for some bots and apps that had stopped working now work once more.
