[#version-display]
= Version display
NOTE: This feature was added in OliveTin version 3000.11.0.
OliveTin can show or hide the application version in the web interface. This is controlled by the **showVersionNumber** policy, which can be set globally or per user/group via xref:security/acl.adoc#_acls_and_policies_global[ACL policies].
== What you see
When **showVersionNumber** is enabled (the default):
* The page footer shows the application name and version, for example: **OliveTin 2024.06.02**.
* If xref:reference/updateChecks.adoc[update checks] are enabled and a newer version exists, a link to the new version may appear in the footer.
* xref:troubleshooting/server-diagnostics.adoc[Server diagnostics] includes the installed version.
When **showVersionNumber** is disabled:
* The footer shows only **OliveTin** (no version number).
* No update-version link is shown, even if update checks are on.
* In server diagnostics output, the version information is redacted, which can be useful for privacy when sharing the report.
== Configuration
The policy defaults to `true` for all users. You can change it in the **defaultPolicy** or override it per user or group in an ACL.
=== Hide version for everyone
[source,yaml]
.`config.yaml`
----
defaultPolicy:
showVersionNumber: false
----
=== Show version only for some users
To hide the version by default but show it for certain users (for example, admins):
[source,yaml]
.`config.yaml`
----
defaultPolicy:
showVersionNumber: false
accessControlLists:
- name: admins
matchUsergroups:
- admins
policy:
showVersionNumber: true
----
=== Show version for everyone (default)
If you do not set **showVersionNumber**, it is treated as `true`. To set it explicitly:
[source,yaml]
.`config.yaml`
----
defaultPolicy:
showVersionNumber: true
showDiagnostics: true
showLogList: true
----
