What's New in Version 3.23.1

- Congratulations to the eagle-eyed winners of this week’s Spot the Difference competition, who noticed that we’d subtly updated the app icon, but had forgotten to mention it. You win our heartfelt admiration, and the pleasant, warm, tingling sensation of having been right all along.
- Fixed: You can now go back and enable notifications for Slack, even if you initially disabled them. Then, you can disable them again. Then re-enable. Up to you.
- Fixed: A crash which could occur when first launching the app, now can’t. Because we fixed it.

Want to see *your* favorite bug featured in this list? We would too. Send along any feedback to, and we’ll see what we can do.

Customer Reviews

Finally, a killer business app!

Long time user of newsgroups, user forums and collaboration software at work (<cough cough> Lotus products <cough>) and have tried numerous applications since social networking hit the mainstream, so when Slack came around I was at first reluctant and dubious of its applicability to my work. After a week or so of using it, I was quite pleased and it has truly enriched my cross-team collaboration, even with colleagues across the oceans and spanning multiple time zones. My team is more productive and we've got the recorded history of the activities for future reference. The search seems pretty robust but we haven't built a huge dataset to pick through yet. I must admit I have yet to crack open a help file or look anything up about its full capabilities, so it's like an adventure when I try something else out and find it is already in the product. Keep up the good work!

Awesome team collaboration application

I so wish my teams would leave mail and get totally into Slack for the work we do. Slack has gotten so much better over the years, especially with the inline threads and emojis, that I'm not sure why any business, group, our team would waste time using emails. For example, like a few times a week I'll get a reply email that simply thanks me for sending something. In Slack that could be done with a simple emoji. Then there's those back and forth emails to make decision. That too can be done in a Slack thread. I can thank of dozens of ways why Slack is ten times better than email. Wish that Apple would more directly integrate with Slack.

Can't live with it, can't live without it

I cannot believe how quickly Slack replaced email, in our company.

It had changed the way we work -- properly used, Slack had increased productivity, helped build stronger bonds with remote workers and allowed closer collaboration. But there is a learning curve to understand what types of discussions are better in email or in person as well as to figure out the right balance of public versus private conversations.
