Upgrade notes
Here's a summary of changes and important notes from Jira 8.2.
Increase pool-max-size
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.
Support for Java 11
Java 11 is now officially supported! For more details, see Supported platforms.
If you're using SQL Server as the database, note that we've updated the Microsoft JDBC driver bundled with Jira to version 7.2.1. This version is required to use Java 11.
Running Jira with Microsoft SQL Server 2017
You can now run Jira with Microsoft SQL Server 2017. For more info, see Connecting Jira to Microsoft SQL Server 2017
End of support announcements
In Jira 8.2, we're making the following changes:
Removing 32-bit installers. The 32-bit installers are no longer available to download. If you need to stick to 32-bit systems, you can still install Jira by using the
zip/tar.gzarchives, as described here.Advance notice: End of support for several built-in importers. In Jira 8.4, we will drop support for built-in importers that are dedicated to specific applications, like Asana, Bugzilla, Pivotal Tracker, etc. You will still be able to import data to Jira, provided that you use the CSV or JSON format.
