Mattermost dot release 4.0.2 for Team Edition (TE) and Enterprise Edition (EE) is now available for download.

If your deployment is affected by issues this dot release fixes, upgrade is recommended. Otherwise, you can upgrade to the next monthly release which also includes these fixes.

This version resolves the following bugs in theĀ Mattermost 4.0 release:

  • Fixed issue when using single-sign-on with GitLab (and in Enterprise Edition with SAML, Office365 and G Suite), where using a non-English language option in Account Settings may result in a login failure (#7231).
  • Fixed issue with custom slash commands not working in direct message channels (#7193).
  • Fixed GitLab and SAML single sign-on in mobile apps redirecting to a browser page (#7258).
