Slack's deprecation schedule

To ensure that we can deliver a consistent experience for our customers, Slack deprecates support for app versions, browsers and operating systems (OS) every six months, on or around 1st February and 1st August. There will be a one-month grace period between end of support (when an app version, browser or OS is no longer supported) and end of life (when it is deprecated completely). This article contains the most up-to-date information on upcoming deprecations and a full record of past deprecations.

Tip: To see which OS and Slack app versions we currently support, visit Minimum requirements for using Slack.
