Jira Software 9.5.x release notes
6 December 2022We're pleased to present Jira Software 9.5.
Upgrading from 8.x to 9.x triggers full Jira reindex that causes some downtime during the process. If you’re on 8.x now, make sure you’ve estimated the downtime and set the best time for the upgrade.

Jira migrates to Log4j2
To take the extra step and ensure continued compliance, we’ve upgraded Log4j to version 2.17.2.
Since this is a breaking change, some effort may be required to ensure that any existing custom Log4j 1.x configurations are compatible with Jira 9.5:
If you’re an admin using a custom Log4j 1.x configuration with your Jira instance, you’ll need to adjust the new
log4j2.xmlfile to include those customizations. For more information about configuring Log4j 2, see Migrating from Log4j 1.x to 2.x and Configuring Log4j 2 in the official documentation.
If you’re an app vendor and your app uses a custom Log4j 1.x configuration, you’ll need to update your code. For more information on what this means for you, see Log4j upgrade details for third-party app vendors.
Audit log improvements
We’ve updated the Audit log feature for a faster loading experience.
The site and project admins might have issues with the Audit log page loading when the database contained more than a few million events. This mostly affected the PostgresSQL and MySQL (including MariaDB) database types.
We’ve fixed this performance issue by incrementally caching the categories and summaries in new smaller database tables. The tables are used to provide options in the categories and summaries filters. The tables are also used for the excluded events selector in the settings.
Here are a few more side improvements provided by the update:
The width of the summaries filter has increased so they can be read.
The inconsistent translation of controls on the Audit log page has been fixed. Audit events, affected objects, categories, and summaries continue to be based on the system locale at the time.

In-product diagnostics updates: new user interface, REST API, and performance metrics
We’ve made several updates and improvements to the In-product diagnostics (IPD) tool to help you monitor and maintain your instance performance:
User interface: You can now manage the IPD monitoring manually in the user interface, with the In-product diagnostics monitoring toggle. By default, the feature is enabled.
The toggle will also be available in version 9.4.3. Check Jira Software release notes for updates.
A new REST API endpoint: We’ve added the
/rest/api/2/monitoring/ipdendpoint for managing the IPD monitoring.
New IPD metrics: We’ve added HTTP connection and mail queue metrics for instance diagnostics. The metrics are available through JMX and the log file
Support for Java 17 added
We’ve added support for Java 17 to boost Jira performance and strengthen instance stability.
Make sure your Jira apps are updated to work on Java 17 and feel free to set up a new environment for Jira deployment.
Because of the added support for Java 17, you might get errors when installing Jira 9.5. Here's how to prevent this
