Mattermost 4.0.3 released

Mattermost dot release 4.0.3 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 the Mattermost 4.0 release:

  • Fixed issue when using single-sign-on with GitLab where using a non-English language option in System Console > Localization sometimes resulted in a login failure (#7231 & #7306).
  • Fixed issue with AmazonS3Region config setting being ignored in Minio file storage setup (#7208).
  • Fixed issue when using high availability mode in Enteprise Edition E20 where the bind address wasn’t set correctly for the hashicorp memberlist (#7254).
