Slack support lifecycle for operating systems, app versions, and browsers

To allow for innovation and keep customer data safe and secure, Slack updates its system requirements every six months in March and September. Read on to learn about our support lifecycle policy and see a list of operating system (OS), app, and browser versions that have recently reached or will soon reach the end of support. If you're using any of the versions listed, upgrade to continue using Slack.

Support lifecycle policy

Slack supports app versions, browsers, and OS for different periods of time, taking into account development cycles and our customers' needs:

OS, app version, or browser Length of support
Slack desktop and mobile apps 12-18 months from release
Browsers 12-18 months from release
Mac, Windows*, and Linux At least 6 months from the time the manufacturer stops OS support
iOS 2.5-3 years from release
Android 4.5-5 years from release

*The support cycle for Windows follows Microsoft’s Enterprise lifecycle schedule, excluding support for LTSC/LTSB.

Note: To keep Slack current in the rapidly evolving market, support lifecycles are subject to change at the sole discretion of Slack, with or without advanced notice.
