What's new

v4.8 [Jul 24, 2020]
Bug fixes:
- Sometimes after an update, the Slack icon would disappear from the system tray. We got some stronger glue, so it should now stay put.
- In rare cases, Slack would simply fail to start altogether. While we’re sure we could all use a coffee break, we know you could also use an application that runs. So we fixed that.
- We made the screen you see when you have connection problems more useful. We also spruced it up a bit with a fresh coat of paint.
- Our notifications system sprung a leak, so we brought it in for a tune-up. Everything should be running smoother now.

v4.3 [Dec 17, 2019]
Bug fix: A more intuitive error page for the unfortunate situation when Slack cannot connect to the internet.

v4.2 [Nov 24, 2019]
Bug fixes: “What is this—a video player for ants?” YouTube videos embedded in Slack can now be expanded to play in full-screen mode, which we’re told is at least three times bigger.

v4.1 [Sep 4, 2019]
Slack 4.15.0
April 12, 2021
Bug Fixes
Previously, clicking on a notification in Windows Action Center didn’t bring you to the message in Slack — basically the opposite of walking into a room and forgetting what you came for, but no less confusing.
Sometimes when the Windows app was launching, it instead decided to hit the Snooze button and just hang there for a while. We gave it a polite talking-to, and it will now be more punctual.
Security Guidance
This release includes minor security improvements. Updating is beneficial.

v3.1 [Feb 16, 2018]
- We got so excited about your emoji we kept requesting them, particularly at the moment you switched channels. This caused all manner of slowness. We've since bottled our enthusiasm, and now request emoji exactly one (1) time.

v3.0 [Oct 28, 2017]
Another important security update.

v2.6 [Apr 21, 2017]
What's New
We revamped video calls, making the experience more intuitive, and more attractive. As a bonus, they're more resource efficient and now let you change audio devices during a call. If that's the kind of thing you need to do.
Remove thine shackles from thine eyes, and behold: gloriously legible text, regardless of your display scaling!
We'll no longer clear notifications from the Action Center automatically, but if you're on the Windows Creators Update we'll bundle them up so that it's easier for you to do.
Fixed
A rare bug that turned Slack into a process hydra: receiving notifications or switching channels would spawn new processes seemingly without end.
The Launch on login preference should be more reliable this time around (for the technically inclined: it now uses the registry instead of a Startup shortcut).
We paved over a series of potholes that were strewn about the app, making crashes far less likely.
Should you ever wish to say goodbye to one of your teams, a right-click > Remove from the sidebar will do the trick now more reliably than before.
Switching teams using the numbered shortcuts is noticeably faster. We would say "37%" if we were forced to put a number on it. Fortunately, we aren't, and we won't.
Opening a context menu won't freeze videos or gifs playing in the app.
We dusted off the cobwebs in the app menu and composted a few menu items that weren't useful when signed into one team.
The default window size is a smidgen larger. You won't notice, because your window will keep being the same size it's always been. That's just the way it is, and we don't want it to change.
Our spellchecker would occasionally mark correctly spelled words as incorrect. It had ONE job. It now performs it.
With surgical precision, we cut out the frame border that appeared when the app window was maximized.

v2.5 [Feb 15, 2017]
- We made the act of signing in more reliable for teams using SSO.
- It transpired that folks who downloaded our installer from slack.com were added to the beta program. If you wanted to be in the beta, you would have said so.
- A crash on startup for Linux customers with a non-English keyboard has been dispatched with a flea in its ear. Because that's just not cricket.
- For the times when Slack just... doesn't: try Help > Clear Cache and Restart. It has all the nougaty goodness of Reset App Data, without the stale aftertaste of losing your teams.

v2.3 [Nov 15, 2016]
Fixed a small bug in Calls.

v2.2 [Sep 17, 2016]
Rather than reloading the whole app, View > Reload now reloads just your current team.
Blank white apps as a result of network troubles should be a rare circumstance.
Launching the app from the Windows command prompt should work more reliably.

v2.1 [Jun 29, 2016]
It was rebuilt the ability to spell-check from the ground up. This edition is steadfast in its red-lining, is flexible if you happen to switch languages apropos of nothing, and should keep you from typing pure nonsense.
Fixed:
- A pesky focus issue that had some customers typing their email or password into the message input if they had tabbed away from the app during sign in has been, thankfully, remedied.
- If you were signed into multiple teams, we were doing one additional redirect for some of them. This expenditure, though small, was unnecessary and so we whittled it away.
- A crash on startup that would happen if someone dropped a folder into the app's log directory. Why would a person do such a thing? We're not sure, but we are humbled by their bravado.
