Team communication software for the 21st century

Slack for Mac

Slack for Mac

  -  98.3 MB  -  Freeware
Slack for Mac brings all your communication together in one place. It's real-time messaging, archiving and search for modern teams. Not just your messages, but all your files, images, PDFs, documents, and spreadsheets can be dropped right into Slack and shared with anyone you want. Add comments, star for later reference, and it’s all completely searchable. If you use any services like Google Drive, Dropbox, or Box, just paste the link and that document is immediately in sync and searchable too.

Connect all the tools you use to the app and avoid all that constant switching between apps. Set up your integration so that you get all your notifications directly within Slack—from support requests, code check-ins, and error logs to sales leads—all of them searchable in one central archive.

Everything in the tool—messages, notifications, files, and all—is automatically indexed and archived so that you can have it at your fingertips whenever you want. Slack for macOS also indexes the content of every file so you can search within PDFs, Word documents, Google docs, and more. With one search box and a set of powerful search operators, you can slice and dice your way to that one message in your communication haystack.

Channels
Organize your team conversations in open channels. Make a channel for a project, a topic, a team, or anything—everyone has a transparent view of all that’s going on.

Private Channels
For sensitive information, create private channels and invite a few team members. No one else can see or join your private channels.

Direct Messages
To reach a colleague directly, send them a Direct Message. It's completely private and secure.

Note: Requires Slack account and 64-bit processor.

What's new in this version:

Slack 4.41.105
Fixed:
- No big fixes to call out this week, but rest assured, there will be more in the future. Not that introducing bugs is our aim, of course. But missteps, adjustments, errors, and corrections — these are the rhythms of life and the price of growth. We hope you’re enjoying the ride, no matter where you happen to find yourself at present.


Slack 4.41.104
Fixed:
- Hard work is happening this week, but nothing we can easily describe. It’s like a duck swimming on a pond. Under the water, the duck is paddling furiously, but on top all that can be seen is the gentle gliding of a bird on water. This week, Slack is the duck.

Slack 4.40.133
Fixed:
- A little reminder as you go about your day: The world is a more unique place simply because you’re a part of it, and you’ve affected others in ways you can’t imagine. Oh, and no big changes to the app this time. Happy messaging!


Slack 4.40.128
- Change log not available for this version


Slack 4.40.126
Fixed:
- We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 4.39.95
Fixed:
- Those using a high-contrast theme at the system level (Windows Settings > Accessibility > Contrast Themes) noted that Slack was not following suit, even when the app was set to mirror system settings. The app is now better at taking direction, in contrast to how it was previously behaving.


Slack 4.39.90
Fixed:
- The app is objectively better today than it was yesterday. This is a scientifically verifiable fact that cannot be challenged or undermined. We appreciate you staying up to date!


Slack 4.39.88
Fixed:
- Users on macOS Monterey and later who were running the App Store version of Slack noticed that they were unable to share their screen, seeing prompts to enable permissions at the system level long after they had already been granted. They say it’s better to ask for forgiveness than permission. In this case, we’d like to beg forgiveness for repeatedly asking permission.


Slack 4.38.125
- This release includes security improvements. Updating is recommended.


Slack 4.38.121
- This release includes security improvements. Updating is recommended.


Slack 4.38.115
- Say hi to Slack AI! Our brand-new set of generative AI tools lets you search smarter, summarize conversations instantly, and much more


Slack 4.37.101
Fixed:
- Nothing to report this time. Well, nothing that you can see, but plenty going on under the surface. We’re working hard to make Slack better; this time it’s not so visible.


Slack 4.37.94
Fixed:
- Screen sharing during huddles on macOS 14.4 will no longer prompt a system alert to allow Slack to capture your screen and audio


Slack 4.36.140
Fixed:
- We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.


Slack 4.36.138
Fixed:
- All bugs that were fixed in this release were too small for the eye to see or too fiddly for human words to describe. Nevertheless, work was done, things tinkered with and the app became subtly better.


Slack 4.36.136
- This release includes security improvements. Updating is recommended.


Slack 4.36.134
Fixed:
- We don’t have anything in particular to call out for this release, but we thank you for staying up to date all the same


Slack 4.35.131
- This release includes security improvements. Updating is recommended.


Slack 4.35.130
Fixed:
- 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 4.35.126
Fixed:
- When the app couldn’t connect, it was failing to display the menu where you could download logs or restart the app. All trouble, no shooting. Those menu options are once again accessible, even if the app (temporarily) is not.


Slack 4.35.121
Fixed:
- Virtual machines were causing actual problems for Slack when both were running simultaneously. We're virtually certain we've eradicated the problem with this update.


Slack 4.34.121
- This release includes security improvements. Updating is recommended.


Slack 4.34.119
Security Guidance:
- This release includes security improvements. Updating is recommended


Slack 4.34.115
Fixed:
-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 4.33.90
Fixed:
- We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.


Slack 4.33.84
- This release includes minor security improvements. Updating is beneficial


Slack 4.33.73
Security Guidance:
- This release includes minor security improvements. Updating is beneficial.


Slack 4.32.127
- We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.

Slack 4.32.126
Fixed:
- We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 4.32.122
- This release includes minor security improvements. Updating is beneficial.


Slack 4.31.156
- Change log not available for this version


Slack 4.31.155
Fixed:
- We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.


Slack 4.31.152
Fixed:
- We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 4.29.149
Fixed:
- We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again


Slack 4.29.144
- Change log not available for this version


Slack 4.28.184
- Change log not available for this version


Slack 4.28.182
- This release includes significant security improvements. Updating is strongly recommended.


Slack 4.28.171
New:
- On Sept. 1, we’ll be deprecating support for some older operating systems and outdated versions of Slack

Fixed:
- 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.

Security Guidance:
- This release includes minor security improvements. Updating is beneficial.


Slack 4.27.154
- 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 <MAJOR.MINOR.BUILD> 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

Fixed:
- 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.


Slack 4.26.1
Fixed:
- We tuned up the engine and gave the interiors a thorough clean. Everything is now running smoothly again.


Slack 4.26.0
Fixed:
- If you tried to re-download a file that was already present in your Downloads folder, the app would pretend to download it again without actually producing a new file. Duplicitous duplication was never part of the plan—sorry about that.

Security Guidance:
- This release includes minor security improvements. Updating is beneficial.


Slack 4.25.0
- 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 4.24.1
New:
- If you've been wanting to use a virtual camera on a video call in Slack, well, now you can! Plug in a custom video feed from your computer, or use a fancy digital camera for crystal clear picture. Daguerreotypes and hand-cranked movie cameras are not supported as input sources at this time.

Fixed:
- 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.

Security Guidance:
- This release includes minor security improvements. Updating is beneficial.


Slack 4.23.0
Fixed:
- 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.


Slack 4.22.0
- This release includes security improvements. Updating is recommended.


Slack 4.21.1
Fixed:
- We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 4.21.0
- This release includes minor security improvements. Updating is beneficial.


Slack 4.20.0
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.

Fixed:
- 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.


Slack 4.19.0
Fixed:
- 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!

Security Guidance:
- This release includes significant security improvements. Updating is strongly recommended


Slack 4.18.0
Fixed:
- 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 4.17.0
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

Fixed:
- 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.


Slack 4.16.2
Fixed:
We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 4.16.0
Fixed:
- 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.

Security Guidance:
- This release includes security improvements. Updating is recommended


Slack 4.15.0
Fixed:
- 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.


Slack 4.14.0
Fixed:
- We improved the restart experience when you’ve gone offline or are having loading issues
- We all have to sign out sometimes. If you sign out of all of your workspaces, you should have an easier time signing back in
- Hopefully you’ll be able to ask “Can you see my screen?” a little less these days. The green border that lets you know you’re screen sharing is back


Slack 4.13.0
Fixed:
- 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
- Change log not available for this version


Slack 4.12.0
New:
- È pronto! Italian language support has landed
- We inspected our app menus and decided they were due for a re-jigging. Give them a whirl and let us know what you think.
- 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


Slack 4.11.3
- Change log not available for this version


Slack 4.11.2
- Change log not available for this version


Slack 4.11.1
- Change log not available for this version


Slack 4.11.0
Bug fixes:
- We’ve tuned the engine and given the interior a thorough clean. Everything is now running smoothly again


Slack 4.10.3
Bug fixes:
- We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 4.10.2
- Bugs fixed


Slack 4.10.0
New:
- Use files? Us too! If you’ve recently used or linked to them on your device, Slack will be slicker at swooping them up and snatching them into your grasp in Slack.
- Updates mean that Big Sur is totally supported in a very holistic, west coast, chill way. It’s, like, totally gnarly. Or sick! Whichever means “good”, basically.

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
- Bug fixes: we’ve tuned the engine and given the interior a thorough clean. Everything is now running smoothly again


Slack 4.8.0
Bug fixes:
- 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
- Upgraded all the backend stuff that the apps run on, resulting in better performance and fewer bugs


Slack 4.6.0
New:
- Batten 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:
- Downloading app updates is less prone to timing out on slow networks, as we’ve extended the timeout to something reasonable
- The Close button has returned to its rightful place on notifications, for all your dismissing needs
- 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
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
- 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
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 4.4.1
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 4.3.3
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 4.2.0
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.

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.
- Using three finger swipes to navigate channel history on touchpad now works again. And for those who never knew it could work in the first place: it does!


Slack 4.1.2
Bug Fixes:
- 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


Slack 4.1.0
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).

Fixed:
- 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 4.0.3
New:
- We’ve updated all the background things to ensure that whenever a new OS update may arrive, Slack will continue to work perfectly. Or, at least, work as expected.

Bug Fixes:
- Now, when we check for network connectivity, it’s more reliable than it was before. Making for a quicker connection, and less frustration.


Slack 3.4.0
What’s New:
- When you lock your device, your status will now, as you might expect, set you as away. Because you are.

Bug Fixes:
- Launch (and Hide) on Login now works better than once it did. Where by "once" we mean "five minutes ago before you updated your version of Slack"
- Our Slack app icon was missing smaller icon sizes, which was both problematic and aesthetically bad. It now renders as it should
- Slack would occasionally crash while you were restarting your computer. We looked at the bug causing this, turned it off and on ag ain, and now it works
- Some people were seeing sidebar icons from other teams they were signed into instead of the icons they were expecting. They will now show correctly
- Any keyboard and cursor actions you may have experienced behaving badly have been shown the error of their ways


Slack 3.3.8

New:
- In a slight change to the way you sign in on desktop, you'll now sign in in the browser rather than directly inside the app.

Bug Fixes:
- The new app icon was looking a little fuzzy on some docks, which simply wouldn't do. It should be much crisper now.
- Equally, the new loading animation was looking a little stretched, or a little squished, depending on how you looked it. It's now practically perfect in every way.
- If you have had problems logging in using SSO (single sign-on), you should no longer encounter those problems.
- We fixed a problem wherein the "Open the Slack App" button in the browser did not, in fact, open the app. Honestly: it had *one* job. It now performs that job.


Slack 3.3.7

New:
- From today, you'll notice a shiny new app button that matches our new logo. You can read more about it on our blog at SlackHQ.com. Change! Everyone loves it. (Having said that, nothing about Slack or how you use it has changed. Just the button.)

Bug Fixes:
- Users signing in with Single Sign-On would see the same message twice when logging in.
- Users signing in with Single Sign-On would see the same message twice when logging in. This will not happen any more.
- When trying to select a portion of a code-formatted block of text (text formatted with ` or ``` at either end), some characters were proving slippery and hard to select. Please copy and paste to your heart's content.
- Several crashes — occurring rarely, and seemingly randomly, on launch and at other times — have been eliminated. More random and rare crashes inevitably exist, of course, and as soon as we know what they are, we'll eliminate those too.
- When downloading particular audio or video files from Slack, the download window will no longer misbehave or look weird.
- If you were running macOS Mojave, we sometimes wouldn’t ask you for permissions for microphone and video even though we needed to, which meant we couldn’t use them. We now will and can (with your blessing, of course).


Slack 3.3.6
- Change log not available for this version


Slack 3.3.3
- Bug Fixes: All updates are important, of course. This one contains security updates, and as we know, they’re the most important kind of all


Slack 3.3.1

New:
- If you're having graphical issues, you can now use the "Disable Hardware Acceleration” in preferences to make things better.

Bug Fixes:
- Overall, stability of the app has been improved, thanks to a bevy of bug fixes.
- We appreciate it when you report issues — so we've improved the diagnostic reporting tools so that we can analyze them, and fix them, faster.
- Having multiple windows open sometimes led to you getting duplicate notifications at once. Whatever the message, it should now just be one ping per tool for y'all, one click to find them.
- Color profiles being slightly different in 3.2.0 may have caused a little flicker, which should now have been extinguished.
- The spellcheck, having had its logic tweaked, to be better at spellchecking, is now a lot bitter at chicken for erroneous spilling ersatz. In Slack.
- When you download something, we're now better at telling you so.
- In fact, notifications in general are noticeably more reliable now, too.
- One particular bug causing the app to crash upon launch has been squished. There may be more. But when we find them, we'll fix those too.
- We’ve tinkered with the internal workings and polished some rough edges. The app is now better than it was.


Slack 3.1.1
- Bug Fixes: 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


Slack 3.0.0

New:
- When you’re in a lot of workspaces, the app now uses much less memory, and starting up is faster, to boot
- And flipping between those workspaces is now faster. Not super-sonic, but certainly somewhere between a jiffy and lickety-split
- We shunted the sign-in page out of the app — it's now rerouted to a new window, for reasons of reliability
- A new-fangled lock badge subtly lets you know which workspaces you're currently signed out of. Or of which you're currently signed out. Either way
- Our start up screen, spruced-up and slimmed-down, is worth a gander — as is the helpful way that dates now stick to the top of a channel while scrolling through messages. Though if you don't notice them, but quietly feel a little bit happier for reasons you can't put your finger on, that's cool too

Fixed:
- It’s been a long time coming but brings us joy to say: 100% less reloading during drag and drop. How much? 100%. That's all the percents, people. Sorry about the previous frustration
- For those encountering a screen claiming "Something’s not working", it turns out the main thing not working was this screen: it is no more
- If you kept the app running for a long time, you might be on the receiving end of two consecutive updates. Now good things come to those who wait, one-at-a-time, as is proper
- The sidebar now scoots considerately out of the way when viewing full-screen video
- We fixed exiting full-screen video when pressing the aptly-named “Escape” key
- The blackout caused by a window being closed while full-screen, with one request confoundingly eclipsing the other, has been sunsetted
- Found: One missing Ctrl-1 / Cmd-1 hotkey. Please call 1-800-SLACKME to claim. Don't actually call that. It doesn't do anything. Unlike the hotkey (now)
- Should you forget what app you’re using, the About Slack window is all new and loads much faster than before
- Scrolling through messages is flicker-free
- There are now no more crashes in High Sierra when starting up the app
- Composing text in an IME (for Chinese, Japanese, and Korean customers) no longer inserts zero-width spaces; in other words, it’s blank-box-free
- The diacritics menu – the place where the alphabet goes to try on different hats and accents – no longer adds a duplicate letter to your input once you've chosen the one you want. We've said it before, but this time we really mëean it
- Pinch-to-zoom gestures could, sometimes, tragically, irreversibly zoom. You can now make things on your screen smaller again without resorting to moving your computer far away
- The popup that appears when you look up the definition of a word has been realigned to make more sense
- And finally, sometimes selecting text in the search box would move the window around. You could say… it was a bit of a drag


Slack 2.9.0
- 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
- A small release containing nothing but another Electron update, this one better than the last


Slack 2.8.1
- 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
- Added bonus: An Electron update improving security. A precautionary measure, but it’s always good to be up to date


Slack 2.6.3
- Fixed: Sometimes if you changed networks, we used to rouse from sleep in a bit of a daze, greeting you with a blank screen. Now, we awaken bright-eyed and bushy-tailed. Or at the very least, with your team displayed
-  Fixed: Where, in rare cases, some external links didn't end up pointing to the right place when you clicked them, they now do
- Fixed: Video playback should now be much smoother, and nicer to your network
- Fixed: On certain keyboard layouts, hitting backspace didn't actually delete the last character, which was a surprise, but a surprise of the lesser kind - there is now one fewer lesser surprise


Slack 2.6.2
- Fixed: Unexplainably, context menus and spell-check stopped working in some teams. OK: we have an explanation but we'd rather not discuss it. It's embarrassing. Rest easy knowing that it's fixed here
- Fixed: We found – and cast out – the culprit behind high resource usage while the app's sitting idle


Slack 2.6.1
- Fixed: If you were experiencing issues making calls on macOS 10.10, you should no longer. Update and keep calling


Slack 2.6.0
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

Fixed:
- 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


Slack 2.5.2
Fixed:
- 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.


Slack 2.5.1
What's New:
- The way we load teams you don't view often has been changed to reduce the app's memory footprint
- Folks consistently unable to load the app will now be greeted by a troubleshooting page that offers suggestions on making their situation better. (Spoiler: it's usually to do with over-zealous antivirus software)
- Those pasting text with style into a Post then finding their text to have "no style" can now Paste & Match Style under the Edit menu
- You can see our Help Center documentation in – of all places – the Help menu. The almost over-intuitively named Open Help Center item will be your friend

Fixed:
- Waking Slack after hibernation or a system crash occasionally found all your teams missing. Thank you for your patience, and sorry for the inconvenience; it no longer should
- Some bold explorers moved their user profile off of the default drive and started the app to find nothing but a cryptic error message. We weren't prepared for this boldness, but have since girded our loins. Fine, explorers: Set your profiles free
- A rare bug where team icons shuffled out of formation in the sidebar. They're more stoic and sticky and as a bonus, rearranging them is smoother
- Customers typing in languages that use IME composition (Korean, for example) will find that the message input is 82% stickier


Slack 2.4.1
What's New:
- The shades of gray in our menu bar were so 1992 — they didn't match any of our outfits. So: we went shopping for a new window frame. This one matches your theme, and comes with a free hamburger menu!
- We discovered that removing a bunch of unnecessary processes improved app startup time. Who knew? Less really is more. Or at least, less is more-faster. Or should that be fewer? Whatever: It's better
- We simplified the way we remember your teams and app settings. This shouldn't affect much, aside from some bugs wherein we forgot your teams or app settings, which are now fixed
- For the savvy troubleshooter, a new tool: Help > Show Logs in Explorer will package up some app diagnostic files, should you ever need them

Fixed:
- Our zoom levels now match the Chrome browser, so you should feel right at home (so long as your home is Chrome)
- An infrequent crash when quitting the app has been dispatched
- A slightly more frequent crash while checking for updates; eliminated
- Signing out of teams from the right-click menu is 46.8% more reliable
- And finally, if you had multiple displays, new windows (such as a call or a Post) would appear on the primary display instead of the display that Slack was on. Rather than submit this to a physics journal for peer review, we decided to fix it. All is as it should be


Slack 2.3.3
- There was a small bug in Calls. We don’t think you saw it, but we fixed it anyway


Slack 2.3.3
- Fixed Window zoom jumping back and forth? No longer–we locked it down and threw away the key


Slack 2.3.2
- Contractions aren't causing spellcheck errors any longer, unless tehy're misspelled
- We fixed a problem with idle timing that made you look inactive and unavailable when truth be told, you were quite busy and attentive. If you were receiving a few too many mobile notifications, this was the culprit
- When typing in languages that require input composition, (Korean, for example!) switching between the input method editor and our app caused characters to go missing


Slack 2.3.0
- Summer is over and that means no more beach balls! ...Get it? Well then, how about this: the app starts a bit faster and switching channels or teams is a bit zippier.
- If you're signed into more than one team, we've removed the titlebar from the window for a streamlined, modern look. High fashion.
- A redesigned team sidebar with better support for light themes, and, as a bonus, it scrolls if you're signed into too many teams (you cosmopolitan!)
- Signing into a new team gets the same full-screen treatment as our other dialogs, because your 8th team could be just as important as your 1st.
- You're now able to approve (and then, with a lighthearted click, open) deep links from other apps.
- Use Help > Report Issue to send feedback or file a bug. It attaches your log files automatically, to make troubleshooting that much simpler.
