Security guidance for desktop app updates

Starting with version 4.14.0, if Slack has made any security-specific improvements to a new desktop app version, the desktop app release notes will include security guidance to help customers to prioritise updating the Slack desktop app. Here’s how to interpret different levels of guidance:

Guidance statement What it means
This release includes minor security improvements. Updating is beneficial. Slack has made minor improvements to the security of the desktop app. Upgrading to this new version will provide users with limited security benefits.
This release includes security improvements. Updating is recommended. Slack has made improvements to the security of the desktop app. Upgrading to this new version will provide users with security benefits.
This release includes significant security improvements. Updating is strongly recommended. Slack has made improvements that are expected to greatly improve the security of the desktop app. Users will gain significant security benefits from upgrading and should prioritise adoption of this new version.

Note: Security guidance should not 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 our customers of any compromise impacting the security of their Slack workspace or client applications.
