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).
