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.

Mac, Windows†, and Linux | At least 3 months from the time the manufacturer stops OS support |
