 アップグレード ノート

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 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. 


New monitors for Jira Data Center

We've created a brand new set of monitors and alerts to help you analyze performance bottlenecks and avoid outages. Now you can monitor slow HTTP requests, slow jobs, high pool utilization, slow and complex JQL and database, and abandoned connections.

The JQL monitors are available also for Jira Server. 

For more information, see Data Center monitoring.



データのセキュリティを最大限に高めるため、初期設定ではパブリック共有機能はオフになっています。また、機密データのセキュリティが維持されるように、フィルター、ダッシュボード、ユーザー権限を確認することをお勧めします。「匿名ユーザー アクセスの制御」を参照してください。

Extra security for Jira 


ユーザー キーの生成が初期設定に

新規ユーザー用にユーザー キーを生成するための新しい方法を導入しました。これによって、ユーザーの個人データを保存する場所の数を減らせます。 

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 ID10100.

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.

新しい Oracle バージョン、新しい JDBC ドライバー

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.

Data Center 向け の Aurora のサポート

Jira Data Center 向けに Aurora PostgreSQL のサポートを追加しています。 

PostgreSQL 9.3 のご利用の終了

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.


Tomcat のアップグレード

We're upgrading Tomcat to version 8.5.42.


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?params has 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...

  • 事前告知: Internet Explorer 11 のサポート終了について

    アトラシアンでは、最新の Web 標準を引き続き活用して、すべての製品で改善された機能と最高のユーザー エクスペリエンスを提供できるようにするため、Internet Explorer 11 のサポートを終了することにしました。 

    Jira 8.5 will be the last version to support Internet Explorer. 

    See End of support announcements for full details.
