The steps to check for Slack desktop app updates vary across Linux devices. Some devices may be configured to use a repository for the Slack app, so when your computer updates, Slack will update, too. The ability to disable this repository or update Slack using other steps will depend on your operating system’s environment.

Note: Some IT administrators may choose to disable app updates for their organisation. If this is the case, you won’t see a badge on the  help icon when an update is available.

Security guidance for desktop app updates

Since version 4.14.0, Slack release notes will include security guidance to help customers to prioritise updating the Slack desktop app, if applicable. Here’s how to interpret different levels of guidance:

Guidance statement What it means
This release includes minor security improvements. Updating is beneficial. Minor security improvements. Upgrading will provide users with limited security benefits.
This release includes security improvements. Updating is recommended. Some security improvements. Upgrading will provide users with security benefits.
This release includes significant security improvements. Updating is strongly recommended. Significant security improvements. Users will gain significant benefits from upgrading, and should prioritise updating to the new version.

Note: Security guidance shouldn't be construed to mean that older versions of the Slack desktop app are insecure. We’re constantly working to reduce the likelihood and data security impact of security issues. We always directly inform customers of any compromise impacting the security of their Slack workspace or client applications.
