Upgrade notes 

Upgrading to 7.17.4

Due to changes required for  CONFSERVER-78179 - Getting issue details... STATUS in Confluence 7.17.4, you won't be able to perform a rolling upgrade to this version. Downtime will be required. 

You must wait for node 1 to start completely after upgrading before you attempt to start the next node, or Confluence will fail to start with an 'Unexpected bytes from remote node' error. If this happens, restart your first node. 

It is always good practice to wait for a node to start up completely before starting the next node. 

Configuring Confluence as an OAuth 2.0 provider

You can now configure Confluence as an OAuth 2.0 client and provider. If you’d like to switch to OAuth 2.0, you’ll need to update your current integrations that use OAuth 1.0 or build new ones compatible with Confluence. To understand what OAuth 2.0 flows are available and what data you need, see the Confluence OAuth 2.0 provider API.

If your integrations are ready to go, learn how to link to other applications.

Change to JMX monitoring

You can now turn JMX monitoring off from the Monitoring page. Previously this was done using the confluence.jmx.disabled system property. 

You won't be able to enable JMX monitoring through the UI on any nodes that have this system property set. 

If you prefer to keep JMX monitoring disabled, we still recommend removing the system property, and instead using the UI to disable JMX. This will allow you to enable it in the future without needing to restart Confluence. 

Faster permissions service

You can now access the faster permissions service from the admin console. You should read the Faster permissions service documentation before enabling this service.

Minor improvements to calendar restrictions

We've made some small changes to the calendar restrictions dialog to make it easier to use and understand. The way restrictions work has not changed.  

Invalid license check

If a Confluence Data Center or Server license isn't valid, system administrators will now see a banner prompting them to contact their license issuer to confirm. 

Upgrading PostgreSQL on older sites

If your Confluence instance previously ran on PostgreSQL 8.x or earlier, it's possible that some of your tables were created with Unique Object Identifiers (OIDs). PostgreSQL 12 removed the special behavior of OID columns.

To avoid problems when upgrading your database, see How to check for unique object identifiers (OIDs) before upgrading to PostgreSQL 12 or later.

Supported platform changes

Added support for PostgreSQL 12, 13, and 14. 

End of support announcements

End of support for Microsoft SQL Server 2016

As previously announced, Microsoft SQL Server 2016 is no longer supported.

Advance Notice: End of support for PostgreSQL 10

Confluence 7.17.x will be the last release to support PostgreSQL 10.

Advance Notice: Removal of Usage stats 

We will remove the Usage Stats feature in Confluence 8.0. 

For more information on these notices, see End of Support Announcements for Confluence

Upgrade procedure

Always test the upgrade in a test environment before upgrading in production.

To upgrade Confluence to the latest version:

  1. Go to Administration  > General Configuration > Plan your upgrade and select the version you want to upgrade to. This will run the pre-upgrade checks.
  2. Go to Administration  > General Configuration > Troubleshooting and support tools to check your license validity, application server, database setup, and more.
  3. If your version of Confluence is more than one version behind, read the release notes and upgrade guides  for all releases between your version and the latest version.
  4. Back up your installation directory, home directory, and database.
  5. Download the latest version of Confluence.
  6. Follow the instructions in the Upgrade Guide.

Update configuration files after upgrading

The contents of configuration files such as server.xml, web.xml , setenv.bat /, and change from time to time. 

When upgrading, we recommend manually reapplying any additions to these files (such as proxy configuration, datasource, JVM parameters) rather than simply overwriting the file with the file from your previous installation; otherwise you will miss out on any improvements we have made.
