What's New

Version 3.2.0

What’s New
• Myriad improvements for the people of Enterprise Grid, including quicker Quick Switching, better proxy support, and direct message draft syncing across multiple workspaces (meaning that whichever workspace you started typing that message in, you can finish in another.)

Bug Fixes
• Unread badges were occasionally unreliable or inconsistent, so we tweaked a few doohickeys to improve them. It worked.
• Smoothed some wrinkles in the loading of Slack calls and boosted general under-the-hood call performance while we were in there.
• We tinkered with the workspace sign-in flow, updating how we handle errors and improving magic link support.
• Copying email links now does what you’d expect (as long as you were expecting it to copy the email link. If you were expecting it to do something like file your taxes for you, you are still out of luck).
• Slack will no longer interrupt macOS when restarting or shutting down.
• After changing displays, pinch-to-zoom gestures will no longer insist on continuing to zoom the app when you pinch.
• Twelve crashes have been fixed. Yes. 12. If you were unlucky enough to experience the full dozen, please accept a) this imaginary medal and b) our sincere apologies.

Slack: Customers asked for feature since 2014, but let's make fun of them for asking


Slack is an okay app, but the team behind it appears to loathe their customers. This is a bold claim, but when you have a company that has known it users wanted "night mode/dark theme" since 2014 (check their Twitter for 10 Nov 2014), not added it yet because "doing accessibility is hard" for 4 years, and then has a Product team with the nerve to harass its customers on Twitter (Kump on 8 Jun 2018) for expecting them to follow through like a quality Mac app - what is the right way to categorize this attitude?

Maybe your Product team should spend more time fixing the accessibility issues you appear to find "unsolvable" for 4 years instead of scoring snarky Internet points.

EDIT: Around a month later & reading both the Developer Response as well as Slack's own Twitter, it seems even clearer to me that the company still doesn't value its customers. The inability to not only provide a temporary solution, providing takedowns on solutions like Sblack that work around your non-delivery, and the lack of a firm commitment on a date on which you'll have any solution due to "rearchitecture" just makes this crystal clear. I for one will be pushing my company to move to other solutions like HipChat or Discord.

Developer Response

Thank you for taking the time to share with us, we appreciate your honest feedback and can definitely understand your frustration around this. We've had to make the difficult choice to focus on certain improvements before others, and we believe that a more accessible Slack is a better Slack for everyone. We're committed to making that vision a reality. We're sorry that Slack isn't better serving you right now, and we hope you'll stick with us while we work to make the experience better for everyone. We're hopeful about the work we're doing now to improve Slack for the future.

Good but could be great :)


Like this chat app a lot. Saves me a lot of time with its built-in features as well as the available integrations. Also a big fan of the styling, makes work chat less boring!

However, noticed with recent update that the "Slack Helper" processes are chugging CPU time, so much so that the fans on my top-spec Macbook Pro run on medium to high. Didn’t have this issue before so I’m sure this is an optimization they just need to make.

One thing I would LOVE to see is the ability to “sleep” a group, so that it didn’t have to be always running in the background. For someone like me, who uses Slack for 9 different groups, having each of those chats actively run leads to each spinning up a Slack Helper process that consumes a fair amount of CPU. Would love to be able to “sleep” less important chats e.g. disable background updates for those groups until I explicitly “un-sleep” it. This would primarily be used for chats of lower priority than others.

Developer Response

Interesting idea about "sleeping" a workspace! You've given us some great food for thought here— thanks for sharing this with us!
