If You’re on These Versions, Update to Continue Using Slack
Slack updates its system requirements twice a year in March and September to ensure a good experience for those who use the platform and to keep data safe and secure.
Read on to learn which apps, browsers, and operating systems will soon no longer be supported by Slack. For a full list of the operating systems and app versions that will be deprecated, see Slack’s support lifecycle.
Slack app versions and browser support
Effective Sept. 1, 2022, Slack can no longer be accessed from these app and browser versions:
- Slack desktop app: 4.19.3 and below
- Slack mobile app: 21.08.20 and below
- Browsers: Edge 89, Firefox 87, Chrome 89, Safari 14.1
If you are using an app version that will no longer be supported, you’ll receive an advance notification from Slack prompting you to upgrade. When a web browser is no longer supported you'll be blocked from using Slack in the browser. You can continue using the platform by upgrading to a supported browser.
Operating system support
Effective Sept. 1, 2022, Slack will no longer support the following operating systems (OS):
- Mac OS: 10.13 and below Windows OS: Windows 10 version 2004 and below
- Windows Server version 2004 and below
- Android OS: 8.1 and below
You can still access Slack if your operating system is not supported, as long as your app is up to date. However, you won’t receive app updates.
Improve your Slack experience
For the best experience, it’s recommended you use the most up-to-date version of Slack. See Slack’s instructions on Update the Slack desktop app to check your app version or update your app.
You may also want to see if your browser is updated to the latest version. Most browsers have a menu item that displays the version you are currently using. Before updating browsers, you’re encouraged to review University IT’s browser recommendations to ensure the latest version is compatible with Stanford's administrative applications.
