--- title: "GitLab 8.5.6 Released" date: 2016-03-15 16:00 categories: releases author: GitLab author_twitter: gitlab filename: 2016-03-15-gitlab-8-dot-5-dot-6-released.markdown --- Today we are releasing version 8.5.6 for GitLab Community Edition (CE) and Enterprise Edition (EE). This version includes one LDAP fix. Read on for all the details! - **CE/EE:** Obtain a lease before querying LDAP ([!3181]) [!3181]: https://gitlab.com/gitlab-org/gitlab-ce/merge_requests/3181 ## Details about the LDAP fix Before the LDAP fix above it could happen that a single GitLab user triggered multiple simultaneous LDAP checks due to a race condition. On large LDAP-enabled GitLab servers, especially with GitLab Enterprise Edition, this could generate unnecessary load on the GitLab server. We now use a 10-minute “lease” in Redis to ensure that at most one LDAP check is started per user during this time interval. ## Upgrade barometer This version does not include any new migrations, and should not require any downtime. Please be aware that by default the Omnibus packages will stop, run migrations, and start again, no matter how “big” or “small” the upgrade is. This behavior can be changed by adding a [`/etc/gitlab/skip-auto-migrations` file](http://doc.gitlab.com/omnibus/update/README.html). ## Updating To update, check out our [update page](/update). ## Enterprise Edition Interested in GitLab Enterprise Edition?
