Jira Core 8.4.x upgrade notes
Here are some important notes on upgrading to Jira Core 8.4.
For details on the new features and improvements in this release, see the Jira Core 8.4.x release notes.
Here's a summary of changes and important notes from Jira 8.4.
Increase pool-max-size on upgrade
If you're upgrading from Jira 7.x to Jira 8.x we recommend changing the pool-max-size parameter to 40 in your dbconfig.xml before the upgrade. Leaving the default of 20 can sometimes lead to “ResultSet Closed” errors during re-indexing on 8.x. For information on implementing the change, see Tuning database connections.
Email notifications batched by default
Email notifications are now batched by default. This means that your users will no longer receive separate notifications for every event, but instead get a summary of notifications for recent events. You can read more about this feature here.
Important: If you customized how your notifications look by editing the Velocity templates, your customizations will no longer work. That’s because batched notifications are using different templates. You will need to reapply your changes to these new templates. But worry not. You do not need to restart Jira after editing the templates.
Here’s how to do it:
- Customizing email content (batched notifications)
- Adding custom fields to emails (batched notifications)
Updates to permissions required
To maximize the security of your data, we’ve made the Public Sharing feature OFF by default. We also recommend that you revise your filter, dashboards and user permissions so that sensitive data remains secure. See Control anonymous user access.
Extra security for Jira
We’ve introduced extra security measures to make sure issue attachments and issue keys are safe and inaccessible for anonymous users.
Generating user keys becomes default
We have introduced a new way of generating user keys for new users. The reason behind it is that we want to reduce the number of places where we store users’ personal data.
Up to now, the user key has been the same as username, lowercased. For example, user
Admin got a user key
admin. If there’s been a naming conflict, the user key has been set to a value like
We’re now changing this approach so that all user keys for new users (no changes for existing users) have the following format:
JIRAUSER10100. This approach becomes the default in Jira 8.4 and is no longer a dark feature.

New Oracle versions, new JDBC driver
We've added support for new Oracle versions — 18c and 19c. If you want to use these versions, see Connecting Jira to Oracle to make them work with your Jira.
While working on this, we've upgraded the JDBC driver that we're using to test Jira with Oracle to JDBC 19.3 (ojdbc8). To be safe, you should also upgrade your driver. This applies to all Oracle versions. You can get the driver here. For more info on what's supported, see Supported platforms.
Support for Aurora for Data Center
We’re adding support for Aurora PostgreSQL for Jira Data Center.
PostgreSQL 9.3 will no longer work
We’ve stopped supporting PostgreSQL 9.3 back in Jira 8.0, but it was still possible to use it with Jira. If you’re one of those who stayed with this database version, now it’s time to upgrade, as Jira 8.4 does not work with PostgreSQL 9.3. For the list of supported databases, see Supported platforms.
We're upgrading Tomcat to version 8.5.42.
End of support announcements
In Jira 8.4, we're making the following changes:
- Deprecation of Jira native importers. We have dropped support for several native importers that used to be available as part of Jira Importers Plugin (JIM). As of Jira 8.4 we're only supporting import from CSV and JSON.
Advance notice: createmeta REST endpoint will soon be removed. This endpoint is commonly used when Atlassian products are integrated to create issues in Jira from a Confluence, Fisheye, or Bitbucket instance. However,
/jira/rest/api/2/issue/createmeta?paramshas been reported to cause issues especially on larger instances. That is why we decided to remove this endpoint in Jira 9.0. In Jira 8.4 we'll make other calls available to mitigate the issue. Read more...
Advance notice: end of support for Internet Explorer 11
To allow us to continue to take advantage of modern web standards to deliver improved functionality and the best possible user experience across all of our products, we have decided to end support for Internet Explorer 11.
Jira 8.5 will be the last version to support Internet Explorer.
