Server vs Data Center
We've updated the names of our Confluence editions on the downloads page.
- Confluence Server is the standard, non-clustered edition.
- Confluence Data Center is the clustered edition, specifically for large enterprises.
Reducing noisy notifications
Notifications will no longer be sent when a page is moved.
Shared home directory for clustered installations
We have introduced the concept of a shared home directory for clustered installations. All cluster nodes will now need to be configured with a path to a directory that is shared between all nodes.
When upgrading from an existing cluster to Confluence Data Center some additional steps apply.
Cache configurations are now stored in:
<confluence-home>/shared-home/config/cache-settings-overrides.propertiesin Confluence Server (standalone)
<confluence-shared-home>/config/cache-settings-overrides.propertiesin Confluence Data Center (clustered)
These files were previously named
Changes to setenv.sh and setenv.bat
Confluence now uses the CATALINA_OPTS environment variable, rather than JAVA_OPTS to pass Java runtime options to Tomcat. The system properties themselves have not changed, but some command line arguments have changed, including memory and garbage collection.
When reapplying any previous customizations you should use the CATALINA_OPTS variable, and take into account that the default garbage collector is now G1 and that detailed GC log files are now generated.
Incorrect license message in footer
If you have a Confluence Starter license and upgrade to Confluence 5.6 you will see the following incorrect message in the footer "EVALUATION LICENSE Are you enjoying Confluence? Please consider purchasing it today". Other license types (commercial, developer, etc) are not affected. See - CONF-34780Getting issue details... STATUS . This issue only affects the appearance of the footer and is not a problem with your license.
We have now released Confluence 5.6.1 which resolves this issue.
Some translations not available in 5.6
Translations for some new features are not available in this release. We hope to make these translations available shortly after this release (in a bug fix release). If you use a language pack other than English, we do not recommend you upgrade to Confluence 5.6 yet.
End of support announcements
- End of support for Tomcat 6.0.x
As previously announced, from this release onward we no longer support Tomcat 6.0.x.
- End of support for Internet Explorer
As previously announced, from this release onward we no longer support Internet Explorer 8.

To help us to make Confluence a more robust and scalable application, we have decided to stop providing an EAR/WAR distribution. This means that the only supported application server will be will be the version of Tomcat that is bundled with each release.
This release (Confluence 5.6) will be the last release to include a EAR/WAR edition.
