Confluence 7.10 Upgrade Notes

Here are some important notes on upgrading to Confluence 7.10. For details of the new features and improvements in this release, see the Confluence 7.10 Release Notes

On this page:

Upgrade notes 

Managed Synchrony memory increase

The default maximum heap size (Xmx) allocated to Synchrony has been increased from 1 GB to 2 GB, so you may need to increase the memory available to Confluence. You can change this default using the synchrony.memory.max system property.  

XStream upgrade

In this release we upgraded the version of Xstream bundled with Confluence. This is a major upgrade that may have an impact on custom apps you may have developed.

See XStream 1.4 upgrade for full details.

You may find that some Marketplace apps are not compatible with Confluence 7.10 on release day. We recommend upgrading Confluence in a test environment, and checking that all your apps start up and work as expected, so you don't get any surprises when you upgrade. If you do find an app doesn't start up, contact the app vendor for assistance.

PostgreSQL driver upgrade

We've upgraded the PostgreSQL driver bundled with Confluence from 42.2.6 to 42.2.16. We don't expect there to be any impact. See the PostgreSQL JDBC driver changelog if you want more details. 

Login with query parameter no longer supported

From Confluence 7.10 we will prevent you from using the os_username+os_password query parameter to log in.

If you have any custom integrations that use this method, you should switch to basic authentication, or consider a more secure option, such as personal access tokens.

If you need more time to update your integrations, you can set the atlassian.allow.insecure.url.parameter.login system property to true as a workaround.

Upgrade procedure

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

To upgrade Confluence to the latest version:

  1. Go to  > General Configuration > Plan your upgrade and select the version you want to upgrade to. This will run the pre-upgrade checks.
  2. Go to  > 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 / setenv.sh and confluenceinit.properties 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.
