Slack for iOS – release notes

Slack 22.06.25

27 June 2022

Bug fixes

Fixed: Scheduling a message to send later was displaying a confirmation in every one of your channels and DMs (rather than just the one where the message would eventually appear). Turns out no one wanted to replicate the panic of accidentally hitting “Reply All” in Slack, so we’ll make sure those messages are a bit better targeted.

Slack 22.06.20

20 June 2022

What’s new

We've made a number of improvements to our search interface. Why? To minimize the searching and maximize the finding. You'll find that keywords are highlighted, tabs are more cleanly formatted and the number of results found is displayed at the top of the list.

Slack 22.06.15

13 June 2022

Bug fixes

No one enjoys the phrase “Have you tried turning it off and on again?” And yet sometimes the channel list was refusing to load without restarting the app. To the delight of support agents and users everywhere, this has been rectified.
Fixed: If at first you don’t succeed, try, try again. Unless of course your file upload failed due to poor connectivity, in which case Slack would refuse any second chances. The app will no longer let past mistakes define it, so you should see more success with retried uploads.

Slack 22.06.10

24 May 2022

Bug fixes

Fixed: File uploads were periodically failing due to temporary file IDs being passed instead of final file IDs. You know how the DMV gives you a Learner’s Permit that’s very important until you get your actual license, at which point it’s just another piece of paper in your glovebox that has no actual value? We, uh, cleaned out the glove compartment, metaphorically speaking.
Fixed: iPad users who joined a Huddle after it had already been started were unable to mute their microphone, meaning everyone on the call would be party to construction noise or toddlers demanding lunch. Now fixed, you may again join Huddles without having to huddle under the coats in your closet.

Slack 22.05.20

23 May 2022

What’s new

When uploading a photo, pictures that you’ve marked as favorites in the Apple Photos app will now include a small heart in the upload preview. Clear UIs, full hearts, can’t lose.

Bug fixes

Fixed: Ironically, tapping the “+” icon was not displaying the full list of workflow commands in a channel. Because, in fact, additional commands were needed. Should have been a minus sign, perhaps.
Fixed: The email icon was missing from emails forwarded to a Slack channel. In case you couldn’t tell from all the Re: Re: Re:s and inspirational email signatures, we’ve added back the icon just to be safe.
Fixed: Trying to share or save Photoshop files previously resulted in a download error. If you took a screenshot of that error and Photoshopped it into a nice congratulatory message, you still wouldn’t have been able to download the Photoshop file, and we’re not sure why we’re suggesting that now.
Fixed: If Slack was set to use the in-app browser, attempting to open a link that was inside a file preview didn’t do anything. The browser and previewer could not be in the same place at the same time, like Batman and Bruce Wayne or Mrs. Doubtfire and the guy who pretended to be Mrs. Doubtfire.
Fixed: The Mentions & Reactions tab will now correctly distinguish between @mentions of your name and uses of your keywords, meaning you’ll no longer see “[person] mentioned you” when a teammate posts about tacos. Unless your display name is @tacos. Who are we to judge?

Slack 22.05.10

9 May 2022

Bug fixes

Fixed: In orgs where a mandatory mobile browser is required, the app was still defaulting to Slack’s in-app browser during sign-in. This would lead to situations where the browser would attempt to auth, be denied, then give up and sulk without providing any alternative. The appropriate browser will now be used, so if you’re locked out it’s your fault now. Probably.

Slack 22.04.20

25 April 2022

Bug fixes

Fixed: When viewing a file on iPad, the menu bar was not appearing, meaning you could not share the file, comment on it, save it for later, or any number of other actions. You could only stare at it, as if in an art gallery. We’re certain that every file you upload is an aesthetic marvel, but we also want to give you tools to work with it.
Fixed: Tapping on a notification while viewing a long thread would sometimes overload the app, leading to an unscheduled power nap. Scales have been rebalanced, energy flow rerouted, and crashes politely declined.

Slack 22.04.10

11 April 2022

What’s new

iPad users, rejoice—a major update this way comes. A new layout more closely resembles the desktop experience, the sidebar has been upgraded for improved organization and navigation, and we’ve added greater support for iOS accessibility options. Get the full rundown here: https://slack.com/blog/news/ipad-app-new-look-improved-functionality

Bug fixes

Fixed: Did you know you can use keyboard shortcuts with the iPad app? Well, now they work as intended! Use CMD + [ and CMD + ] to navigate back and forth through your recently-viewed conversations.

Slack 22.03.20

28 March 2022

Bug fixes

Fixed: Changing a channel's description in the channel details screen would actually update the channel's topic, while changing the topic would update the description. We have ascertained that it is not, in fact, “Opposite Day,” which would be the only plausible explanation for such a thing. Additionally, Opposite Day is not a real thing. Or is it, and this denial is actually a confirmation? It is (it is not), so we did not fix this bug (we fixed it).

Slack 22.03.10

14 March 2022

What’s new

When previewing a channel prior to joining, you’ll now see the channel description displayed with the channel name to provide a bit more context. For when you’re unsure whether #the-owls is a channel for ornithologists, insomniacs or fans of the show Twin Peaks.
If you’re someone whose workday doesn’t start at 9 am (or if you find Slackbot alerts first thing in the morning to be less of a pick-me-up and more of a put-me-down), you can now choose when your “Tomorrow” or “Next Week” reminders will appear. Head over to Preferences > Notifications to set the default that works best for you.

Bug fixes

Fixed: Tapping on a message link from an app would always take you to the parent message, as opposed to a specific threaded reply. That was about as helpful as asking for directions to the Liberty Bell and being told it’s somewhere in Philadelphia. We took another crack at the design and recast it into something more appealing.

Slack 22.02.20

28 February 2022

What’s new

A friendly heads-up: In order to keep up with the growing capabilities of newer operating systems, this is going to be the last version of Slack that supports iOS 13. You’ll still be able to use Slack, but to receive new updates you'll first need to upgrade to iOS 14.
We fixed a host of small bugs around creating messages and lists with Korean characters. What is the proper name for a group of bugs? A bundle? A bandolier? We fixed a benediction of bugs.
Ever reply to a thread only to realize you should have sent that reply back into the main channel? Us too. That’s why you can now retroactively share your threaded messages with the rest of the channel. Just press and hold on the message in question, then select “Send Reply to This Channel” to give it the attention it deserves.
Menus, begone! Now you can turn that text into a hyperlink by simply highlighting and pasting your URL right on top of it. Same old words with a brand new tappable destination.
The first time you send someone a direct message, you’ll now see their pronouns displayed at the beginning of the conversation. We hope it’s a small step that will help foster respect among colleagues.

Bug fixes

Fixed: Expanding the message composition view to full screen was not actually changing the size of the text box. It was an illusion, like those tricky pictures of vases and faces, or the idea of “just one more episode.” Enjoy composing on a larger canvas once more.
Fixed: Starting a Zoom call in a channel by tapping the channel name and scrolling down to “Start a Call” was not working. At all. Not even the momentary ring of a canceled pocket dial, or an immediate hang-up like when you got dared to phone your crush at a sleepover. Well, now it works. Please Zoom responsibly.

Slack 22.02.10

15 February 2022

Bug fixes

Fixed: When sharing a file to Slack from another app, Group DMs were missing names altogether, showing only blank spaces and commas. As exciting as it was to treat file sharing like the throwing of a bouquet at a wedding, sending messages at work requires a great deal more precision.
Fixed: If you were viewing someone’s profile in the mobile app, we were sometimes displaying long and ungainly URLs instead of clean, tappable links. These did not spark joy, so we have tidied up with a spirit of gratitude.

Slack 22.01.30

31 January 2022

What’s new

You can now sort your conversations by Recent Activity! Tap the button in the top-right corner of your Home tab to see the tidy new timeline.

Bug fixes

Some folks were reporting being stuck in an SSO loop, repeatedly being asked for authentication like the worst kind of merry-go-round. A dismal-go-round. You can now get into the app and off the ride.
The “Call” option was missing when viewing a teammate’s profile. Contrary to popular belief, this was not due to an “always text before calling” design philosophy, but was simply a mismatch of code.

Slack 22.01.20

18 January 2022

Bug fixes

Fixed: If you were viewing details about an app in your workspace and then tried switching to the Messages tab, the app would load for an uncomfortably long time. It was like a lengthy silence in the middle of a story, where you’re not sure if the speaker is pausing for effect, has lost their train of thought, or has become entranced by a squirrel passing by the window.

Slack 22.01.10

3 January 2022

Bug fixes

Fixed: When the app was in dark mode, hyperlinks were displaying in a low contrast color that was hard to read. Dark mode was designed to make things easy on the eyes, not to simulate reading by candlelight, so we bumped the brightness up a few notches.

Slack 21.12.10

6 December 2021

Bug fixes

Fixed: Feel like life (specifically in GIF and emoji form) has been passing by too quickly? That was actually a bug affecting Slack on the iPhone 13 Pro. Moving images will once again animate at the proper speed.
Fixed: When delivering notifications for channels in which there were only 2 members, our system was being a touch informal and dropping the conversation name altogether. Titles have been reinstated so you’ll know whether that message is coming from #you-and-i or #just-the-two-of-us.
Fixed: If you start a Zoom meeting by typing /zoom, you will find that the “Join” button now works as intended, meaning you can no longer blame this bug for being late to your call. We’re sorry / you’re welcome.
Fixed: The official Apple symbol (option + shift + K on a Mac keyboard) was not displaying correctly in all areas of the iOS app. Worry not, these were simply a few bad apples, fallen too far from the tree.
Fixed: Bulleted lists with punctuation were sometimes being sent with unexpected line breaks, making each statement feel isolated and a teeny bit passive-aggressive. That’s not what we were going for, and we’re sorry for any lists that seemed extra confrontational on our account.

Slack 21.11.20

15 November 2021

What’s new

The channel list just got easier to command! Tap and hold on any channel or DM in the Home tab to mark a conversation as read, mute notifications, copy the channel name or leave it entirely. All this with the press of a finger.

Bug fixes

Fixed: Custom status information was not reliably showing up in all corners of the app, meaning you might have been halfway through writing a message before noticing the person you were DMing was on a plane. Or walking their dog. Or they had the :coffee-parrot: emoji as a status and you know that when Brian is :coffee-parrot: it’s not the best time to ask about meditation apps. Well, now that status will be visible no matter where (or how caffeinated) you are. How’s that for peace of mind?

Slack 21.11.10

1 November 2021

Bug fixes

Archived channels, while showing up in the “Jump to…” menu, were sitting preserved and inaccessible in a hermetically sealed corner of the app, as if holding a grudge for having been archived. They’ve since made nice, and you can once again access those channels for the historical data contained therein.

Slack 21.10.20

18 October 2021

What’s new

If you’re using Slack Connect to share a private channel with another organization, we’ll make sure it stays private on the receiving end. That is, there is no option when accepting a private shared channel to make it public. More peace of mind for you, more security for all.

Bug fixes

Fixed: Notification sounds were always delivered with the “Device Default” sound, no matter what you had selected. It was like if a restaurant handed you a menu and then served you meatloaf regardless of your order. No offense to meatloaf.
Fixed: Some images with unique sizing (panorama photos, cropped screenshots) were not displaying properly after being uploaded. The app is now more welcoming and inclusive of pictures of all shapes and sizes.
Fixed: It was discovered that certain messages containing non-English characters and emoji would sometimes end up truncated when sent. A mystery, to be sure, but no less irritating at the end of the day. Going forward, your full and complete messages will be delivered, however they are composed.
Fixed: We regret to inform you that copying a list of bullet points from Slack and pasting it elsewhere will no longer result in the bullets turning into castle emoji.

Slack 21.10.10

4 October 2021

What’s new

You can now record video and audio clips right within Slack. Add some face time to your team updates, talk through feedback, or just say hello. Want to sing your portion of the stand-up? Best check with your manager on that one.
Channel sections can now be collapsed or expanded with a tap of your finger, making for a tidier, more focused experience.

Slack 21.09.21

27 September 2021

Bug fixes

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

Slack 21.09.20

20 September 2021

What’s new

If you’re running the new iOS 15, you’ll now see avatars for message senders on your push notifications. Because we all could use more friendly faces these days.
Slack now integrates with iOS 15's Focus Mode, so that when you need a moment of calm and re-centering we will not knock-brush you right out of it.

Slack 21.09.11

9 September 2021

Bug fixes

We’ve tuned the engine and given the interior a thorough clean. Everything is now running smoothly again.

Slack 21.09.10

7 September 2021

Bug fixes

Fixed: Adding someone to a private channel with the /invite command was dropping them right in without asking for confirmation. We have reconfirmed the inclusion of the aforementioned confirmation, and things are once again hunky-dory.

Slack 21.08.20

23 August 2021

Bug fixes

Fixed: A gnarly little bug caused a crash for some people trying to mention others in a message. We carefully captured the bug in a metaphorical paper cup and released it out the metaphorical front door, at which point our metaphorical neighbor walked by and offered us a real slice of blueberry pie, which was incredible.
Fixed: If you poked around in the settings of a Slack app, you may have seen emoji displayed as text like :this: instead of looking like the intended emoji. This has been fixed, and emoji should appear correctly. :thumbs-up: all around.

Slack 21.08.10

9 August 2021

What’s new

This will be the last version of Slack that supports iOS 12, which means this is the last version that supports devices such as iPhone 5s and 6, iPad Mini 2 and 3, iPad Air (1st generation), and iPod Touch (6th generation). In addition, starting on September 1st, you’ll need to be running iOS 13.3 or later in order to connect to Slack. We know this is potentially frustrating news, but these minimum requirements are necessary in order to ensure Slack remains as secure and seamless as we built it to be. Thank you for your understanding.

Bug fixes

Fixed: When using markup, adding a closing backtick after a period would not end the code section. You may now punctuate to your hearts’ content, safe in the knowledge that code blocks will not continue ad infinitum.
Fixed: Those of you using VoiceOver may have noticed that a recent update made it much more difficult to swipe between messages. The reasons why are about as exciting as trying to navigate through the bug itself, so suffice it to say that things should just be better now.
Fixed: A memory issue was causing the app to crash more often, primarily on older devices. There’s no way around it — crashes are frustrating. We’re doing our best to minimize their frequency, and we appreciate your patience.

Slack 21.07.20

26 July 2021

What’s new

How’s everybody doing out there? Are you getting enough sleep? Drinking enough water? Eating some vegetables here and there? We don’t have any big updates this time around, so we wanted to use this space to remind you to be kind to yourself and those around you. That’s all. Love ya.

Slack 21.07.10

12 July 2021

Bug fixes

Fixed: Copying text from a Slack message and then pasting back into Slack sometimes resulted in a crash and/or a rift in the known universe. We’ve patched this bug (as well as any outstanding wormholes), and our scientists assure us the app is once again safe to use in this timeline.
Fixed: For users of the Japanese Kana Flick keyboard, the “Smart Full width spaces” setting should now work as expected, as well as inserting new text into the middle of a message. You might say we flicked both of those bugs off the table.

Slack 21.06.32

1 July 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 21.06.30

28 June 2021

Bug fixes

Fixed: Those who had VoiceOver enabled were not able to access URLs within messages. It’s pretty frustrating when an Accessibility option makes an app less accessible, so we’ve made sure this works now.

Slack 21.06.20

14 June 2021

Bug fixes

Fixed: Tapping on an empty input field used to show the options for “cut” and “copy,” but there was nothing to select. What do you copy when there is no text? If you copy text that isn't there, does it even exist?
Fixed: When editing a channel’s topic, changes were being saved even if you tapped “cancel,” essentially telling the app, “Yes, absolutely do that right now” instead of “Undo.” This bug has now been undone.
Fixed: Beginning a message with a “slash” would cause the shortcuts menu to open, which then had to be dismissed before you could return to composing your message. Shortcuts are for saving time, not adding to it, so our inadvertent “longcut” has been whittled down.
Fixed: Sometimes your workspace would indicate “-1” new users had joined, which was pretty spooky. While our terms of service do not have a specific clause against nonexistent individuals using Slack, we have made the executive decision to limit all workspace members to those denoted by positive integers.

Slack 21.06.11

4 June 2021

Bug fixes

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

Slack 21.06.10

1 June 2021

Bug fixes

Fixed: Attempting to send a message via Quick Reply (replying to the notification) would sometimes not send a message at all. This was frustrating for the sender, embarrassing for us, and not befitting at all of the moniker “quick.” Replies of all velocities shall now be supported.
Fixed: Previously, attempting to start a new thread would simply kick you back to the main channel view without so much as an apology or explanation. This has been rectified so that no matter where you go, there you can thread.

Slack 21.05.20

17 May 2021

What’s new

We’ve spruced up the channel list for your enjoyment. You’ll now see profile photos alongside direct messages and all the names associated with a group DM. We’ve also improved accessibility, adding support for larger text sizes, more accommodating tap targets for your fingers, and additional actions when using the VoiceOver rotor.
Small thumb update (er, the update is small, but it applies to any size of thumb or appendage) — if you follow a link from one channel to another, swiping to the right will now take you back to the previous channel instead of the channel list.

Bug fixes

Fixed: For some people, channels remained bold and unread-looking despite being very read. This was rather unpleasant and is now fixed.

Slack 21.05.11

7 May 2021

Bug fixes

We’ve tuned the engine and given the interior a thorough clean. Everything is now running smoothly again.

Slack 21.05.10

3 May 2021

What’s new

We’ve improved support for dynamic type in key iOS screens, meaning that if you’re using larger text or font settings, Slack will do a better job of making those readable. Fun fact: written language is most useful when people are able to read it.

Bug fixes

Fixed: However you choose to pronounce GIF, you can once again paste them into Slack. Let the memes flow.

Slack 21.04.20

19 April 2021

What’s new

If you’re well versed in Simplified or Traditional Chinese — or aspire to be one day — you can now use Slack in those languages. Set your language preferences in You > Preferences > Language.
A bit daft, but drafts are now available everywhere you use Slack. Start a message on your computer and finish it on your phone. Snap a photo of a whiteboard sketch, attach it on your phone and finish the message on your computer.
We’ve made it easier to express emotions or, to put it more accurately, send an emoji in Slack. The message input is now accompanied by an emoji button for you to find and select an emoji that best fits the situation.

Bug fixes

Fixed: An unfortunate bug caused the /invite slash command to crash the iPad app. You can now quickly invite people without ending the party.
Fixed: The /giphy slash command stopped working in threads. This may have left your train of thought in tatters as you were unable to weave the right GIF into the conversation at the right time. The bug has been mended and you can “/giphy thimble” in threads to your heart’s content.

Slack 21.04.10

5 April 2021

What’s new

Put the people you work with at the top of your list. Now, when you tap the “share” icon in any iOS app, your Slack DMs and MPDMs will appear right up top.

Slack 21.03.20

22 March 2021

Bug fixes

Fixed: Sometimes, setting your status to “Away” didn’t work, and your teammates thought you were screening their messages. We’ve fixed that, so now you can safely go away and be “Away.”
Fixed: It used to be that if you opened an image in Slack in full-screen mode, rotated your device to landscape, and dismissed the image, Slack would get stuck there. We’ve finally mastered going back the way we came, so dismissing the image should now take you back to good old portrait mode.

Slack 21.03.10

8 March 2021

Bug fixes

Fixed: You can once again reorder the workspace switcher with a tap, hold and drag. Everything is in its right place, including your workspaces.

Slack 21.02.20

22 February 2021

What’s new

Fans of the workspace switcher, take note: First of all, we are flattered you consider yourself a fan of the workspace switcher. Chuffed, even. Second, we’re giving it a refresh, so you can better distinguish your workspaces and switch between them more easily.
For some, search is the heart of Slack. Now, it’s also the feet, because search is moving to its own tab at the bottom of the app.

Bug fixes

Fixed: If a message from an app had a button, and that button had an emoji in it, the emoji would appear like :this: instead of showing the emoji itself. This bug was very :woman-gesturing-no:, and is now fixed.

Slack 21.02.10

8 February 2021

Bug fixes

If you were to select “People” in the workspace menu, pick someone, click “Message,” and then try to send the message, well, this used to be too much for Slack. Not anymore. Send away!

Slack 21.01.20

25 January 2021

Bug fixes

Fixed: Custom emoji appear in the picker, right where they should – as opposed to not appearing at all.
Fixed: When using one of your team’s homemade workflows, entering Japanese or Korean characters no longer adds bonus, unintended Japanese or Korean characters.
Fixed: App messages were missing the colourful line that appears alongside their buttons and forms. No longer! Colour has been returned to all the places that it should be.
Fixed: When you’re reacting to a message, Slack puts your most-used emoji up front – because that’s a helpful thing to do. Recently, and in very specific circumstances, Slack has been showing blank spaces instead of emoji. This is much less helpful. And now it’s fixed.

Slack 21.01.10

11 January 2021

Bug fixes

Fixed: Previously, tapping on a link from an app in Slack might have taken you to an unsettling place: nowhere. We fixed that, so now you’ll land in the right place at the right time.

Slack 20.12.10

14 December 2020

What’s new

Sharing files into Slack from outside Slack – say, from your photos app – is now much nicer than before. You’ll see your teammates’ pictures, and their full names, so it’s easy to make sure that you’re sending the right file to the right person. Should things have always been this way? Yes! And so they are.

Bug fixes

Fixed: The ‘Add a file’ button will now work as you might have expected it to, adding files aplenty to your channels and DMs.
Fixed: People who choose to auto-collapse images in Slack were occasionally seeing black squares in the place of delightful GIFs. No more! Now your GIFs will surprise, delight and inspire, at least as much as any one GIF can.
Fixed: Tapping and holding on emoji reactions now shows you the list of people who have reacted. This is an improvement on its previous behaviour, which was to crash the Slack app entirely.

Slack 20.11.21

7 December 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 20.11.20

30 November 2020

Bug fixes

Fixed: For the briefest of moments after opening Slack, DMs would sometimes appear unread even if there wasn’t a new message. It was so quick, you might not have noticed, but we fixed it anyway.
Fixed: Sometimes, if you opened the description of an app in Slack, you might encounter some ~strangely~ *formatted* _text_. These app descriptions now appear beautifully formatted, as the developers intended.
Fixed: When you step away from your computer to enjoy a sandwich, drink some water or just stare into the middle distance for a while, you can now tell Slack how long to wait before sending your notifications to your mobile device. Take your time.

Slack 20.11.10

9 November 2020

Bug fixes

Fixed: if you were invited to an audio chat and accepted the invite on desktop, sometimes the mobile app continued to ring. It wasn’t your alarm; that was us. We’re very sorry for the extra ringing in your ears, and now things have gone back to normal.
Fixed: your app may have crashed while you were in the middle of formatting a message that had hyphens and spaces. We fixed this, so that you can practise proper punctuation without pesky interruptions.

Slack 20.10.20

Slack 20.09.10

14 September 2020

What’s new

Bugs were squished, performance was improved, work was done, and the result was good. Please enjoy Slack responsibly.

Slack 20.08.30

31 August 2020

Bug fixes

Fixed: If you’ve been using an external keyboard with your iPad, you might have tried to accept an auto-correct suggestion and found that Slack sent your message-in-progress instead. Hitting enter at times like these will now accept the suggestion without sending your message early, as you’d want it to.
Fixed: When an image was viewed full-screen, swiping did not dismiss it properly. You may now swipe and dismiss images with confidence.

Slack 20.08.20

17 August 2020

What’s new

We can’t think of any references, cultural or otherwise, that involve swiping left or swiping right. But now, if a message has more than one image, you can tap one of them and swipe left or right to browse between images.

Bug fixes

Fixed: Ever tapped a search result or a saved message and ended up in the right channel, but not at the right message? No? That’s good to hear. But if you have, we’ve fixed it. No more surprise endings — now you’ll always end up exactly where you planned.

Slack 20.08.10

3 August 2020

What’s new

New: For something you’ve read but need to come back to later, you can now mark a thread as unread! Hurrah! Long-press on the message you’d like to start from, and then select the option to mark unread from the menu. Yes, you’ve been able to do it with channel messages for a long time, but now, you can do it in threads too. Useful!

Slack 20.07.20

20 July 2020

Bug fixes

Fixed: A few of our sidebar themes were taking dark mode a bit too seriously and obscuring the status bar. You’ll no longer have to choose between the comfort of your retinas and being able to check the time.
Fixed: iPad users noticed that long-pressing on a pinned or starred item in the Channel Details section caused the app to take an unforeseen nap. It’s better-rested now, so hopefully that won’t be happening again.

Slack 20.07.10

6 July 2020

What’s new

You can now customize your notification preferences on a per-day basis, which is a fancy way of saying that you can now pause interruptions with Do Not Disturb down to the day. (Looking for a feature to pause interruptions from pets, kids, or package deliveries? We feel you.)

Bug fixes

Fixed: On mobile, some messages from apps would display with missing text. It certainly was not our intention to pull a vanishing act, so we’ve fixed that.

Slack 20.06.20

22 June 2020

What’s new

This is the last version of Slack that will work on iOS 11. To get updates in the future, you’ll need to update your device to iOS 12.2 (or newer).

Bug fixes

Fixed: December 31, 1969 was a fine day (we’re pretty sure). It was not, however, a day in which you received any direct messages, regardless of what our app previously claimed.
Fixed: Some files could not be deleted, and not for lack of trying — the option to delete those files was missing from the menu. This has been fixed and all files can be deleted as desired.

Slack 20.06.10

8 June 2020

Bug fixes

Fixed: The /remove command is now working properly, so those with permission can once again remove people from channels if they need to.
Fixed: A pesky bug tried to cut your messages short. We’ve restored the limit to the intended 12,000 characters per message. Write on!

Slack 20.05.20

25 May 2020

Bug fixes

Fixed: If you were in a workspace that required secondary authentication, then previews of notifications from that workspace were always hidden (even if you wanted to be able to see them). Now, the previews will show up like normal — as long as you’re currently authenticated. (You can also, as always, choose not to show previews of the messages).

Slack 20.05.10

11 May 2020

TL;DR: We’ve redesigned the layout of the app. Read more about the improvements on our blog at SlackHQ.com or in our help center. Here though, we’ll stick to what’s new, and what has been fixed.

What’s new

What’s new? Most things. We changed almost all of the things. So many things! Much change.

Bug fixes

Previously, it was complicated to get to the four main things people do on mobile. We’ve fixed this with a new nifty navigation bar at the bottom of the app containing: a Home view for your sidebar, DMs, (still listed most recent first), Mentions (for quickly catching up), and You (because you’re great) (and also because setting your status/preferences on mobile needed to be easier).
The quickswitcher on the desktop app is wonderful, but we discovered an issue where people weren’t using it as much on mobile. So we made the Jump To box more prominent (and smarter) to fix this. Fingers crossed!
It seemed bizarrely hard to create a new message in a channel or DM without finding that precise location first. With an application of logic, software engineering, and a new “Compose” button in the bottom right corner, this has been rectified.
Our apologies to people who have been wanting to easily set reminders, start workflows or access favourite apps in channels and conversations — it was hard to work out how to do that on the move. A new lightning bolt under the message box now gives quick access to shortcuts, and thereby solves this age-old problem.
And finally, it came to pass, as time went by, that in the old version of the app, there was a lot of swiping back and forth to get places. We’ve simplified that: Now, swiping right will reveal your workspace and preferences, and swiping left will get you back to the last conversation you were in. With this change in behavior, we hope to give you the powers of both omniscience and time travel. nbd.
And yes. We know. Change is hard! All our fingers have all built up muscle memory, but after continually adding features and functionality over the years, we needed to step back and make sure things made sense. You can find more about these improvements in our blog post, and as always, we welcome your feedback. Thank you for reading all the way to the bottom. We appreciate it, and you.

Slack 20.04.20

27 April 2020

What’s new

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 20.04.10

13 April 2020

Bug fixes

Fixed: When a message held more than 5 images, a button telling you how many more images were included but hidden (+3, for example) was… not making them any less hidden. Basically it wasn’t working. It now works.
Fixed: When sharing a file you will now only be able to share with users or channels that are active in the selected workspace (and not deactivated users, which could occasionally be selected before)
Fixed: On an iPad, tapping “Archive Channel” will now archive the channel. Instead of crashing the app. Right impulse, overenthusiastic execution.

Slack 20.03.30

30 March 2020

What’s new

Minor improvements have been made, and bug fixes taken place, but they’re the kind that are out of sight, behind closed doors, and quietly just doing their job, deep in the inner workings of the app, making things just a little bit better.

Slack 20.03.20

16 March 2020

Bug fixes

Tapping the “Tap to expand image” button was sometimes not, wait for it… expanding the image. It will now do the thing it promises. No more, no less.
Using two-factor authentication, which is a brilliant idea in general for all things, was occasionally not working if multiple types of authentication had been enabled (app, SMS, etc). Let nothing dissuade the security-minded: it now works seamlessly once more.

Slack 20.03.10

2 March 2020

Bug fixes

Fixed: Sometimes, when sharing a file to Slack, some usernames appeared, very unhelpfully, as blanks in the list of direct messages, identifying your colleagues as “@“, instead of say, “@jane”. This is now fixed.
Fixed: Sometimes an app or bot would send a long message containing beautiful formatting and links. And sometimes, the formatting didn’t render correctly or the links were untappable and that, we feared, risked angering the bots, as well as not being very helpful for the user. Now, the formatting is honoured, tapping the links works perfectly and the bots are, for now, placated.

Slack 20.02.20

17 February 2020

Bug fixes

Fixed: Sending a “/me” command that contains an emoji made things crash. /me had no idea this was a thing but is glad that it’s fixed :relieved:

Slack 20.02.10

3 February 2020

Bug fixes

Fixed: While on a call, people using bluetooth sometimes heard a loud noise not generated by the other people on their call. This was not a ghost, it was a bug (and is now fixed).
Fixed: the /msg and /dm commands that were not acting as they should, now work as expected. For those who didn’t know they existed or worked in the first place, they do, and weren’t, but now are.
Fixed: When uploading an image or file from your camera roll to a channel, multiple channels appeared to be selected. Then you couldn’t deselect them. These shenanigans have been shut down and sharing works as it should.

Slack 20.01.20

20 January 2020

Bug fixes

Fixed: @mentioning a user in some languages caused that mention to appear twice. In any language, one mention per message is enough.
Fixed: Translations for @channel and @here were broken in non-English languages. They now work once more in those languages and continue to work in English. Just remember, everyone – if you’re going to @channel, please @channel responsibly.
Fixed: Attempting to send a message that exceeded the character limit would show an error and then delete all of the entered text. This was both hard to trigger (those limits are high!) but very frustrating. The limits still exist, but we now no longer clear everything in the message box.
Fixed: After leaving a workspace, some users were unable to convince that workspace to leave their sidebar. It will now, gracefully, take its leave when asked to.
Fixed: Trying to sign up with a password too similar to your email address resulted in a message that simply read “Error joining team”. We still want you to have a good password… but that error message will now be clearer to point that out.
Fixed: It came to pass that typing, pasting or otherwise entering a large amount of text into the app (the app in this case meaning “the Slack app”, hereinafter referred to as “the app”) on occasion caused that app to undergo issues that would take on the appearance of disappearance or dissolution or, in common parlance, it would appear to crash and need to be restarted. This abdication of our sworn responsibility to take messages of differing length, from the very shortest (e.g. “k”) to the very longest (albeit with an error explaining the imposed character limits of messages and the need to curtail said message), was careless, if not derelict, in our duty, and we have thereby rectified it with an application of technological code that will forthwith allow the entering of large amounts of written matter in the message box of Slack, the app, without risk of unexpected app closure, thus giving free rein to the celebrated verbosity and eloquence of our users in allowing them to enter as large an amount of text as their heart desires, albeit with the expectation that one too long may result in the error message listed several items (perhaps screens?) above this one. Tl;dr: The app was sometimes crashing before as though we had some kind of problem with long pieces of text. We don’t at all.

Slack 20.01.10

6 January 2020

Bug fixes

Fixed: Workspaces were sometimes showing a default workspace icon (a letter on a coloured background) instead of the nice custom icon they had been given. Behold: they are beautiful once more. Or, at the very least, correct. Which is sometimes all we can aspire to.
Fixed: Some complex URLs were being incorrectly treated like email addresses. They will now be treated… wait for it… like URLs.
Fixed: In a message from a bot, buttons and menus configured to respond to a user’s actions weren’t actually doing that. This was not the first stage in a robot uprising: it was merely a bug. And is no more.

Slack 19.12.10

9 December 2019

What’s new

For those who love to format their messages on the move, good news, you can now get that done in a few clicks using the new formatting tool in the message field.

Bug fixes

Fixed: When loading messages containing a lot of custom emoji, the app was sometimes getting overexcited to the point of paralysis. We have calmed the app down and this should no longer happen. Emoji away.
Saving a file from Slack and then attempting to open it from the Files app was occasionally causing the app to crash (which was bad). It is now causing the file to open (which is better).

Slack 19.11.20

18 November 2019

What’s new

The size of text is now controlled in the Accessibility settings of your iOS device rather than inside Slack. We used to have a separate preference for it inside the app, but it makes a lot more sense that you would want to have the same size text whatever you’re reading.

Bug fixes

Fixed: Attempting to reorder your workspaces would occasionally result in them ending up in a completely different order than the one you put them in. The order in which you put them? Either way, they no longer belie your reasonable commands and will fall into line as requested, no longer out of order.

Slack 19.11.10

4 November 2019

What’s new

A swish new icon in the top left-hand corner of the app will show the number of notifications you have in your current workspace, as well as taking you to the sidebar, where you can swipe between your channels and conversations, as before.

Bug fixes

Fixed: Sometimes, attempts to delete a message that had failed to send (due, usually, to low connectivity) were themselves failing. Doubling down on things is great – but not, perhaps, when that thing is “failure”. Now, when one thing doesn’t work, the other will.

Slack 19.10.20

21 October 2019

Bug fixes

Fixed: On smaller devices, the text on menu items in the “Advanced” menu was unfairly clipped. We love devices great and small: and our menus now reflect that (and make more sense).

Slack 19.10.10

7 October 2019

What’s new

Dark mode users who launched the app for the first time were met with a bright white screen. That was less than ideal. Our sign-in screens now match the rest of the app.
All the default sidebar themes are now dark mode compatible – so when you shift into dark mode, your default theme will subtly shift to complement it.

Bug fixes

Fixed: Uploading multiple files at the same time is now more reliable than it was.
Fixed: In an act of overzealous ennui, sending “/shrug” without any text following it was causing the app to crash. Quite ridiculous. If there was ever a message that could stand alone, it was this. For the good of all humanity, it now works once more.

Slack 19.09.20

23 September 2019

What’s new

The app now fully supports iOS 13. In particular, and most pleasingly, we now follow the system settings for dark mode, so the app will automatically “go dark” at the same time as your other apps. Good news in dark times.

Bug fixes

Fixed: Somewhat oddly, notifications were only clearing once you’d read *all* of your mentions. The ones you’ve read will now be the only ones cleared from the notification centre when you launch the app, leaving the ones you haven’t to be read at your leisure.

Slack 19.09.10

16 September 2019

Bug fixes

Fixed: Replying to a notification works much more often than it used to. 99% of the time, in fact, which is so close to 100% we can almost smell it.
Fixed: Swiping between channels with two fingers now will now include the “Threads”view, but only, smartly, if you’ve used that view recently.
Fixed: Custom emoji weren’t always rendering correctly in bots and attachments sent via the Slack API. Now? Emoji = :100:.

Slack 19.08.21

10 September 2019

Bug fixes

We’ve tuned the engine and given the interior a thorough clean. Everything is now running smoothly again.

Slack 19.08.20

26 August 2019

What’s new

If you, like all rational people, arrange your phone screens by colour, you’ll now be in quite the quandary, as we’ve added a couple of extra background hues for the app icon. You can find them under Settings -> App icon – just under Dark mode, which is useful, as the new shades work particularly well with that.

Bug fixes

Fixed: When selecting a new profile picture, users were being asked to confirm that picture twice. We now respect your ability to recognise your own face the first time around and will not ask you again.
Fixed: Uploading slow motion videos is now 100% more successful.
Fixed: Custom emoji uploaded on desktop are now, vitally, transferred at lightning speed so that they're immediately available in the iOS app.

Slack 19.08.10

12 August 2019

Bug fixes

Fixed: When viewing your starred items, unstarring an item will now remove it from the view rather than making you close and reopen the list.
Fixed: A crash that could occur when a message contained a highlight word, an @-mention and certain non-English characters. We’ve fixed it, completely.

Slack 19.07.30

29 July 2019

Bug fixes

Occasionally, some users were unable to sign in. Given that that's the very first thing we want people to be able to do, we squished the bugs we knew about… but if you ever find more, let us know.
Fixed: Many Slack apps that use BlockKit show confirmation dialogues to allow you to confirm your action and, in some cases, those weren't working. They are now.
Fixed: Users who attempt to confirm their email address after their original email link has expired can now resend that email and then confirm it, and thus log in. Again, people being able to log in to an app is a very important part of the user experience. We’re committed to ensuring they can do that. Back in business!

Slack 19.07.20

15 July 2019

What’s new

As of this update, we’ve removed 3D Touch functionality from a few places inside the app – channel names and DMs – where, let’s be honest, it simply wasn’t doing what it should do. 3D Touch still works on the icon on the home screen and when quick-replying to a notification, as it’s perfectly up to scratch there. (N.B. “Scratch” is not a valid gesture, please don’t go scratching your device on our account.)

Bug fixes

Fixed: When viewing the channel details screen in dark mode, the area showing the channel title is now, like everything else, also in dark mode.
Fixed: Where two channels or users had the same name, they’ll no longer randomly switch places with each other in the channel/DM list.
Fixed: Opening a thread containing a message with a link that contained certain characters made everything crash. And yes, seeing as you asked, that one was satisfying to hunt down. And to fix.

Slack 19.07.10

1 July 2019

What’s new

The first message in a channel or direct message now includes a date header, so you can tell what day it is (or was).

Bug fixes

Fixed: Where sharing a file from Slack to another app did not on occasion work, it now works.
Fixed: And sometimes, when sharing a file did work, it would change the file name from words to a series of numbers. Great for robots, terrible for humans.
Fixed: Messages that included the same custom emoji more than once with no space between them were only displaying that emoji once. So :emoji::emoji: was only appearing as :emoji:. You now receive all the emoji you desire, and no fewer than you deserve.

Slack 19.06.20

17 June 2019

Bug fixes

Fixed: Where you were promised the ability to add a link to an emoji through the Slack API so that people could tap that emoji and be transported to the link, we were not making good on that promise. We’ve fixed the bug preventing it from working and everything’s rosy now.
Fixed: Some custom bot names were not being displayed correctly, but now they are.
Fixed: The list of apps in a group conversation would sometimes show the list of users instead of apps. And apps aren’t people, are they?
Fixed: Some message buttons wouldn’t display a confirmation dialogue when tapped, which was a bit odd and slightly confusing. Now it’s been fixed.

Slack 19.06.10

3 June 2019

What’s new

Typing Cyrillic characters now allows you to find users or channels containing those characters as easily on iOS as it has been for a while on desktop.

Bug fixes

Fixed: When starting a group conversation that included one or more single-channel or multi-channel guest users, sometimes previously selected users were being deselected. Not any more. Now you’re all in that together.

Slack 19.05.21

28 May 2019

Bug fixes

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

Slack 19.05.20

20 May 2019

What’s new

Want to upload multiple images at the same time from the message box? In both channels and threads? Of course you do. And now, you can! Hurrah.

Bug fixes

Fixed: In some fonts, using asterisks to make part of a sentence bold would result in all of the text after the bold words *also* being in bold. While we like to believe that fortune favours the bold, it has come to our attention that this is not what that phrase means. So we fixed it.

Slack 19.5.1

6 May 2019

What’s new

This is the last release that will support iOS 10 and therefore the last version that will run on 32-bit devices such as the iPhone 5, iPhone 5c and fourth-generation iPad. To continue receiving Slack updates, please upgrade to iOS 11.1 or later.

Slack 19.4.2

23 April 2019

What’s new

Olá, hola and nice to see you (to see you nice). From today, Slack supports three new languages: Brazilian Portuguese, Latin American Spanish and UK English. You can change this in the settings menu under, not unexpectedly, “Language”. Jolly good! Carry on, everyone.

Slack 19.4.1

8 April 2019

Bug fixes

Links in some Slack app buttons were not working, taking you nowhere instead of the expected somewhere. They now whisk you away to the URL you thought they would take you to in the first place.

Slack 19.3.2

25 March 2019

Bug fixes

Fixed: Screenshots and other .png images sent over Slack were looking blurry. We applied a little focus and now we’re in the clear. If the blurriness persists, you might want to consider an eye test.

Slack 19.3.1

11 March 2019

What’s new

Dark mode can now be switched on (or off) in the Settings menu. Yes, it’s been a long road, but there’s finally dark at the end of the tunnel. N.B. This is mobile-only for now, with desktop coming later – thank you for both bearing with us and for continuing to expect more of us.

Bug fixes

Fixed: The text welcoming you to Slack the very first time you launched the app didn’t quite fit the screen on smaller devices. Not the biggest problem in the world (literally), but first impressions count.
