Here’s to the copycats who recently were unable to copy over the Slack version name from the About Slack dialog. Since we suspect you are not actually cats but rather amazing humans just trying to get your work done, we have meow fixed this issue.
This release includes minor security improvements. Updating is beneficial.
Slack 4.31.155
March 27, 2023
Bug Fixes
We tweaked some things too small to notice or too difficult to explain. We’ll return you to your regular, more interesting types of release next time (we hope).
Slack 4.31.152
March 20, 2023
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.31.150
March 20, 2023
What’s New
Starting with version 4.31, we are no longer able to support Windows 8.1, Windows Server 2012 and Windows Server 2012 R2. If you’re running one of these operating systems, you may continue to use version 4.29, but we encourage you to upgrade your OS to enjoy the latest Slack features (https://slack.com/help/articles/115002037526-System-requirements-for-using-Slack).
Organizations will be able to manage Slack desktop client settings during rollout and ongoing operations. Configurations can be deployed with industry standard tooling: Group Policies on Windows, user preferences profiles on Mac and with configuration files on Linux.
See https://slack.com/help/articles/11906214948755
Pressing the Alt key now serves as an Alternative way to open the app menu bar. We hope this change does not provoke any Altercations between you and your computer.
Bug Fixes
You might have noticed that Slack notifications weren’t coming through when you had another app in fullscreen mode (even if your Focus Assist settings should have allowed them). We’ll do a better job of getting you the notifications you need in accordance with your preferences.
Using the shortcut Ctrl + Shift + F will now toggle to Fullscreen mode, allowing you to really take in the view (or just focus a bit more).
Our notifications misunderstood the “auto-hide” setting for the Windows taskbar, thinking that they should be the ones hiding behind the taskbar while this setting was active. Have you ever seen a child playing hide-and-seek and at least 50% of the kid’s body is visible while they’re “hiding” behind a chair? It was like that, but less cute.
This release includes minor security improvements. Updating is beneficial.
Slack 4.29.149
November 14, 2022
Bug Fixes
We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.
Slack 4.29.144
October 25, 2022
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.
Slack 4.28.184
September 27, 2022
Bug Fixes
We tweaked some things too small to notice or too difficult to explain. We’ll return you to your regular, more interesting types of release next time (we hope).
This release includes significant security improvements. Updating is strongly recommended.
Slack 4.28.171
August 24, 2022
What’s New
On Sept. 1, we’ll be deprecating support for some older operating systems and outdated versions of Slack. Please visit our Help Center to get all the details: https://slack.com/help/articles/115002037526-System-requirements-for-using-Slack
Bug Fixes
Trying to capture your screen with a third-party app while also sharing your screen in Slack may have resulted in the non-Slack app crashing. We’d like to say that this was because the idea of “capture” is antithetical to “sharing,” but in truth it was just a “bug.”
Sharing your screen and then right-clicking the Slack icon in the taskbar made you the winner of a secret game. The prize was that the app would crash. Nobody liked that.
If you’re someone who uses a symlink for your %appdata% folder and noticed that Slack was crashing on startup, we have some good news: Slack won’t be crashing anymore. If you don’t use symlinks, well, this note doesn’t apply to you, but we appreciate you reading anyway.
Dragging the Slack window between multiple displays was resulting in some spooky behavior, like the window snapping to locations where you distinctly did not drop it. “Haunted Slack” launches in 2025, but until then we must insist all ghosts be unambiguously busted.
This release includes minor security improvements. Updating is beneficial.
Slack 4.27.154
June 14, 2022
What’s New
You may have noticed that with this release there’s a new, larger number at the end of the version string. Going forward, while you’ll still see the numbers laid out in a sequence, the “Build” numbers will now correspond to specific builds on our end as opposed to a small sequential number. TL;DR: A few more numbers for you, a bit more specificity for everyone.
We’ve added the most common Apple and Microsoft file extensions to our approved list so you won’t be asked to confirm each time you open a Word doc or Keynote presentation. Are you sure you’d like one less approval? YES/NO
Bug Fixes
If you had notifications disabled at the system level, Slack had very crafty ways of evading the preventative measures of Windows. Not by design, mind you—it was a bug. Can bugs be crafty? Not when they’re squished.
This release includes minor security improvements. Updating is beneficial.
Slack 4.26.3
May 31, 2022
Bug Fixes
Clicking on a notification was sometimes causing the app to stop responding, breaking its silence only to say “Slack is not responding.” No one enjoyed that, so we’ve endeavored to make sure that doesn’t happen anymore.
Slack 4.26.2
May 16, 2022
Bug Fixes
We tweaked some things too small to notice or too difficult to explain. We’ll return you to your regular, more interesting types of release next time (we hope).
Slack 4.25.2
April 11, 2022
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.25.0
March 24, 2022
What’s New
Starting today, you’ll see a confirmation pop-up when a link in Slack is prompting another program to open. If you don’t want to see these each time because you enjoy living on the edge, just check the box “Always open files of this type.”
Slack 4.24.0
February 28, 2022
Bug Fixes
Perhaps you wanted to know which version of the app you had installed. Maybe we gave you an option to copy that version number to your clipboard. It’s possible the “Copy” button did nothing at all. One might say we fixed it.
We discovered that when an update to the app failed, people were still being notified that the update was a success. There is a time and place for “fake it ‘til you make it,” but this was not one of them.
This release includes minor security improvements. Updating is beneficial.
Slack 4.23.0
December 7, 2021
Bug Fixes
Depending on how the app was installed, the “Launch on Login” option was sometimes appearing greyed-out, visible but inaccessible, like a storefront window display after closing hours. We’ve unlocked the door, flipped on the overheads and fired up the neon “Open” sign. Come on in and have your pick of all the preferences.
Some external URLs were occasionally launching within the Slack app window, but will now load in your default web browser, as is proper. Slack cannot have a little web page, even as a treat.
This release includes minor security improvements. Updating is beneficial.
Slack 4.20.0
September 20, 2021
What’s New
When opening SSH, FTP, SFTP or SMB links, you’ll now see the option to allow all future URLs from just that same domain instead of the whole wide world. A little more secure for us, a little more peace of mind for you.
Bug Fixes
Certain versions of the app were not correctly changing availability to “Away” after 10 minutes of inactivity.
While this has been fixed, we’d like to remind you that you can use your Custom Status to let your teammates know your whereabouts beyond simply Active or Away. Examples include: walking the dog, catching up after PTO, taking a mental break, or tweeting nice things to the Slack social media team.
This release includes security improvements. Updating is recommended.
Slack 4.19.3
August 25, 2021
Bug Fixes
We tweaked some things too small to notice or too difficult to explain. We’ll return you to your regular, more interesting types of release next time (we hope).
Slack 4.19.2
August 18, 2021
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.19.0
August 11, 2021
Bug Fixes
If you had the “Launch app on login” preference selected, we stopped showing a checkmark next to it after the app restarted. Strong systems require checks and balances, and we’re pleased to report ours now has one more check.
Did you know that pressing the Esc key will mark the channel you’re viewing as read? Or that pressing Shift + Esc will clear ALL of your notifications? Well, now you can do that without being pulled out of fullscreen mode. See our full list of nifty keyboard shortcuts by pressing Ctrl + / the next time you have Slack open!
This release includes significant security improvements. Updating is strongly recommended.
Slack 4.18.0
July 14, 2021
Bug Fixes
If you moved the app window between multiple monitors, notifications were slow to appear on the correct screen. After some orange slices and a halftime pep talk, notifications will be sticking with the app wherever it may go.
Certain menus were not being properly translated when switching languages in the app. You know what they say about menus — they’re most helpful when you can read them.
Slack 4.17.1
June 4, 2021
Bug Fixes
Some folks using the newest generation of processors were experiencing the app crashing. Crashes are no fun, particularly when they involve shiny new things, so this has been fixed.
Slack 4.17.0
June 3, 2021
What’s New
Bigger is better, or rather, closer is clearer. We now support additional zoom levels up to 200% to reduce the strain on your precious peepers.
Bug Fixes
Previously, you may have expected the “Launch on Login” option to do precisely that when clicked. But sadly it didn’t. Pre-flight checks have been rerun, and we are prepared to initiate countdown once more.
You can no longer select incoming notifications as a shareable screen when on a Slack Call. To anyone who noticed this was even possible before, we salute your fastidiousness.
This release includes security improvements. Updating is recommended.
Slack 4.16.1
May 6, 2021
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.16.0
May 4, 2021
Bug Fixes
Images and notifications were sometimes sharing real estate...inelegantly. We have given them both a talking-to, and they have agreed to joint custody of that section of the screen.
This release includes security improvements. Updating is recommended.
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.
This release includes minor security improvements. Updating is beneficial.
Slack 4.13.0
February 16, 2021
Bug Fixes
When you move or resize Slack, we assume you are indeed trying to move or resize it — and so the crash that was regularly happening, instead, was unwelcome. We’ve fixed this. Here’s to properly-sized screens!
We’ve fixed several accessibility issues. Making Slack more accessible is a continuous journey, and we’re quite grateful that you’re along for the ride!
Slack 4.12.2
January 8, 2021
Bug Fixes
We tweaked some things too small to notice or too difficult to explain. We’ll return you to your regular, more interesting types of release next time (we hope).
Slack 4.12.1
January 7, 2021
Bug Fixes
We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.
Slack 4.12.0
December 14, 2020
What’s New
È pronto! Italian language support has landed!
You can now attach recently used files–in one click–from the paperclip menu. Hasty screenshotters, the world is yours.
Bug Fixes
Some small but important accessibility improvements for those navigating with VoiceOver or a screen reader.
As a dancer gracefully recovers from a minor tumble, so shall our app gracefully reload whilst throttled by network failures.
Repeat after me: the app window will not change size after clicking a notification.
Slack 4.11.3
November 25, 2020
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.11.1
November 11, 2020
Bug Fixes
We tweaked some things too small to notice or too difficult to explain. We’ll return you to your regular, more interesting types of release next time (we hope).
Slack 4.11.0
November 9, 2020
Bug Fixes
We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.
Slack 4.10.3
October 15, 2020
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.10.0
October 6, 2020
Bug Fixes
Sometimes, you could not exit full screen mode with escape on windows, which was wrong, because that’s literally what escape means. Now, it works.
We fixed some issues that caused window resizing of Slack to be difficult. We never want to be difficult.
Quickly switching workspaces caused problems. Switching workspaces should only cause opportunities, so we fixed that.
There were a few little bugs that caused crashes, like bugs do. We fixed those, and we’ll fix the next ones too.
Slack 4.9.0
September 2, 2020
Bug Fixes
We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.
Slack 4.8.0
July 23, 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.
Slack 4.7.0
July 2, 2020
What’s New
We’ve upgraded all the backend stuff that the apps run on, resulting in better performance and fewer bugs.
Slack 4.6.0
May 21, 2020
What’s New
Batten down the hatches! The app sandbox is now enabled for all web content. This is a fancy way of saying we’ve dialed up the security of the app. It wasn’t unsafe before, but it’s double safe now.
A preference that allows you to choose a unique save location per download, instead of choosing a folder for all of them. For the choosy types.
Bug Fixes
Your notifications should be tidily grouped by workspace when shown in the Action Center.
A tricky case where some users were unable to get to the browser to add their first workspace.
The Launch on login preference showing the wrong value, when the app was installed from the MSI package.
If you found yourself, in some distant past, trying to start a song on Spotify with your keyboard’s play button, and it did not respond to your command while Slack was front and center, pesky hardware media keys were the problem. And this version is the cure.
The app should be less spicy to your CPU when you’re viewing certain network error pages.
When a download completes, we’ll show an in-app prompt rather than a bothersome system notification.
Slack 4.5.1
May 11, 2020
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.5.0
April 21, 2020
What’s New
We’ve upgraded all the backend stuff that the apps run on, resulting in better performance and fewer bugs.
Our spell checker has been swapped out for a newer model that’s faster, leaner, and capable of fixing your typos in… wait, can this be right? “Multiple languages at the same time”! Open the “Language & Region” preferences to choose your languages. And for whoever it is out there requires that functionality: our hats are off to you. We can barely type in one language right now.
Slack 4.4.2
March 31, 2020
Bug Fixes
We're always working on performance improvements - and this release repairs a previously broken performance diagnostic tool. You won't notice a difference, but we'll have an easier time improving Slack.
Slack 4.4.0
March 18, 2020
Bug Fixes
Fixed: Windows Action Center notifications were unable to display certain characters, like < or ‘ for example.
Fixed: Switching notification types on Windows would cause both types of notifications to be shown until the app was restarted.
Fixed: On Windows, if users landed on our error page, the main menu wasn’t available, which was an error in itself. The error on the error page is now de-errored.
Fixed: If you zoom way in or zoom way out, and then open the About Slack window, the About Slack window would also be zoomed way in/out, which was a little intense.
Fixed: Once in a while, users would receive a flood of notifications for old messages. This was not a bad case of deja vu: it was a bug. And now, a fixed one.
Slack 4.3.4
February 10, 2020
Bug Fixes
A more intuitive error page for the unfortunate situation when Slack cannot reach the internet.
Slack 4.3.2
January 21, 2020
What’s New
We've tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Bug Fixes
Slack would sometimes crash when the user right-clicked to see the context menu. In context, that was unhelpful. So it no longer does that.
When maximized, the app had developed a bit of a distracting flicker. That flicker is now part of Slack history.
Occasionally, a restart would result in connectivity issues for Slack… now you should be back online and back to work lickety-split.
Slack 4.3.0
December 16, 2019
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.2.0
November 26, 2019
What’s New
Our newest, fastest, best-performing, shiniest, most nutritious and delicious version of Slack is now fully rolled out, so that’s the one you’re now using. Brilliant.
Like zooming in and out? Use a numpad? Great news. You can now do these things, on that.
Bug Fixes
Notifications looked weird if your workspace name was long. Now, no matter your team name, notifications look lovely.
Some messages were being marked as read when Slack was hidden behind applications, or not visible on screen. Now we won’t mark it as read until you’ve actually seen it. Which seems fair.
Slack 4.1.2
October 18, 2019
What’s New
We added support for Windows 10 Focus Assist priority list. So now our built-in and Action Center notifications will respect your Focus Assist settings, staying as quiet (or as loud) as you want them to be.
A new menu for the system tray lets you take control of how and when Slack launches on booting up (even, randomly, if you are not signed in to any teams.)
Bug Fixes
Receiving a gif in a notification could mess with your notifications.
Long workspace names now no longer appear as incredibly long in menus.
Slack menus should now be showing up at the right language (meaning the one that is right for you).
Spellchecker stopped working for a small count of users, leading to a shorp uptick in avoidabull erratz. With spellcheck now fully back online for those users, any remaining typos are officially not our fault.
There was a slim chance things weren’t finishing up properly when closing Slack. We’re working on making all this perfect, but in the meantime, it is, at least, better.
Restarting when clearing cache now works again.
No longer do you have to ask “Update.exe? What IS that?”: We now show with our actual name (which is “Slack”, for reference) in Startup entries for Taskmanager and Settings.
Slack could go into a state where getting notifications (even if you couldn't see them) would prevent you from clicking on the right side of your monitor… at all. Sorry for any understandable frustration this caused — your notifications (and your ability to use your mouse) are now working as intended again.
Slack 4.1.1
October 8, 2019
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.1.0
October 1, 2019
What’s New
Thanks to a few tweaks to the engine, a polish of the pistons, and recalibrated valves, the app should be running smoother and faster, than before.
Spellcheck, revamped, is now a much better version of its old self (and back on Linux, to boot) — now it supports Greek, Portuguese and British English. So now spelling correctly should come more naturally to us all (which is good, because “correctly” can be a difacult word to spell).
Bug Fixes
For a quicker connection, and less frustration, checking for network connectivity is more reliable than it was before.
After uploading a video into Slack some found it would give an infinite circle of loading, but not play, which was never our plan. Now: it works! It plays; no more circle! Because, it turned out, all circ and no play made Slack a null ‘ploy.
Slack 4.0.2
August 19, 2019
Bug Fixes
Videos in channels were found to be the cause of a minor (but pesky) memory leak that has now been well and truly plugged.
It's taken a few tries, but the app should now crash less often when connected to an external display. Hopefully.
On opening your computer, the app is now, thankfully, more likely to launch properly every time. And, if you're using the direct download version, you can choose whether that launch is in the background, or front and center.
We spruced up the notifications a little so now they'll not only show up every time you need them to, they'll show up looking like whatever theme you wear proudly on your sidebar. Neat.
Now whenever an app update is available, we'll send you a polite little notification to tell you so.
If you'd become used to opening Slack from a shortcut on your desktop or menu… you'll know that we broke that recently. Sorry about that. It is now unbroken once more.
While using focus assist in Windows, we'll now assist that focus further, by no longer serving you noisy notifications. Sorry about that.
Using the alt key to move focus to the menu is great… but was a little over-excitable. Should you tap it by mistake (or otherwise), it will no longer take ALL the focus, and you can continue to do other things.
Slack 4.0.1
July 25, 2019
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 4.0.0
July 8, 2019
What’s New
Slack is now a tiny bit faster all around, thanks to a bunch of little changes that each made a difference for the better.
Bug Fixes
Drag and dropping files into Slack is now much more stable.
If you ever do need to reset the app's data, it now works better. A bit better, at least.
We improved team icons alignment in the side bar for those in a lot of workspaces. It's a small thing, but much more aesthetically pleasing.
Hardware acceleration can now be turned off without foregrounding Slack. If you know what that means, you'll know it's handy. If you don't — it still is! Carry on. And thank you for reading.
Slack 3.4.3
June 6, 2019
Bug Fixes
The app was crashing more often than it should have done upon waking. Waking up is hard for all of us, but it shouldn't have been that hard. It now crashes less often than it did, and we're continuing to work toward making that "not at all".
Slack 3.4.2
May 23, 2019
What’s New
Just as day follows night and winter gives way to spring, so have we updated Electron to 4.2.1.
Bug Fixes
Tweaked the way that push notifications work between desktop and mobile to make them (hopefully) better for everyone. And faster.
Some minor tweaks to the stability of the app (to make it more stable, to be clear)
Slack 3.4.1
May 3, 2019
Bug Fixes
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.
Slack 3.4.0
April 18, 2019
Bug Fixes
Interactions with network drives are now handled with grace and panache. Or, at the very least, "better".
If you want to launch slack minimized, you now can. We will no longer stand in your way.
We've changed the look, feel and texture of our new HTML notifications. Give them a try! They're delicious.
Sometimes on Windows 10, moving the window, say, up would cause a white bar to appear. We raised the bar.
Also, moving the window would sometimes change the size of the window. Your aim was true; we no longer move the goalposts on you.
In the Apps and Features and Uninstall a Program window, the icon showing up was not the right one. It now is.
The notification and unread indicators on the taskbar are now more readable.
Blurry icons were an issue for some users with multiple displays. Now all is clear.
The Slack icon, previously appearing with an opaque background color on Windows 10 is now all the clearer for being less clear.
Some people were seeing sidebar icons for teams other than the one they were in. This was confusing, and has now stopped.
And finally, if you have been having issues with keyboard or cursor issues, you should no longer be having them.
Slack 3.3.8
March 7, 2019
What’s New
When you sign in, you'll now sign in through the browser rather than within the app.
Bug Fixes
We've fixed the tray icon to make the notification badge easier to see, because, let's face it, if you can't see a notification, it's not really doing its job.
Switching from one channel to another will now give the correct name and information of the new one, rather than the old one, as was previously happening.
The new loading animation was a little stretched, or a little squished, depending on how you looked at it. It's now practically perfect.
A few icons in menus went missing on Windows 10, and have now been retrieved.
Occasionally, the "Open the Slack App" browser button was not opening the workspace in the desktop app. Silly, really. It now does.
If you use SSO (Single Sign-on) to log in, it should now work perfectly every time.
Slack 3.0.5
January 18, 2018
Bug Fixes
Another important security update. See? We told you they were all important.
Slack 2.9.0
November 16, 2017
What’s New
Slack now officially, and fully, supports Japanese. Along with the already available French, German, Spanish, and, of course, English (of the US variety). Find them under Languages & Region in your preferences menu.
Slack 2.8.2
October 16, 2017
What’s New
A small release containing nothing but another Electron update, this one better than the last.
Slack 2.8.1
September 29, 2017
What’s New
Previously in Slack app releases: we fixed the Japanese input in 2.6.3. Then we re-broke it in 2.8.0. And now it’s fixed again. Stay tuned for the next thrilling installment.
An important Electron update improving security. A precautionary measure, but it’s always good to be up to date.
