アップグレード ノート
Here's a summary of changes and important notes from Jira 8.3.
Increase pool-max-size
Jira 7.x を Jira 8.x にアップグレードする場合は、アップグレードの前に dbconfig.xml で pool-max-size パラメーターを 40 に変更することをおすすめします。デフォルトの 20 のままにしておくと、8.x でインデックスの再作成を実行する際に “ResultSet Closed” エラーが発生することがあります。変更の実装の詳細については「データベース接続のチューニング」を参照してください。
DVCS connector plugin upgrade
The DVCS connector plugin that's bundled with Jira Software has been upgraded to maintain compatibility with the GDPR changes made in Bitbucket Cloud. How the DVCS connector plugin connects to Bitbucket Cloud will change with Jira Software 8.3, and it will require the Webhooks permission. If you connect Jira Software to Bitbucket Cloud, it's important that you check your current permissions in Bitbucket Cloud BEFORE you perform the Jira Software upgrade, and if you haven't already granted the Webhooks permission, you recreate your OAuth token following the steps on the Connect Bitbucket Cloud to Jira Software Server page. If you don't do this prior to the upgrade, some of the upgrade tasks may fail. If this happens, you'll need to update the permission and reinstall the DVCS connector plugin.
AdoptOpenJDK JRE 8 is bundled with Jira
Jira is no longer bundled with Oracle's JDK, and instead comes with AdoptOpenJDK JRE 8. Note that this applies to Jira installers. If you're installing Jira manually from the archive, you need to install JDK by yourself.
Support for Oracle 12c Release 2
We have introduced support for Oracle 12c Release 2 database, which remains under Oracle's Premier Support.
atlassian-jslibs を 1.4.1 にアップグレード
We have upgraded the atlassian-jslibs plugin from version 1.2.5 to 1.4.1 and are now bundling React 16.8.6 , ReactDOM 16.8.6 factory, and Marionette 4.1.2 with Jira.
アップグレード後にカスタム変更の一覧を表示
When you upgrade you need to re-apply the changes you've made to your old Jira files to the same files in the upgraded version of Jira so that your custom changes are preserved. Up till 8.3 we were not able to tell you exactly which files you've modified. However, as of 8.3 we can. When you start your Jira after upgrade, you'll see a list of files which have been modified so that you can easily transfer the changes to the new version of the files.
Migrating from Jira Cloud to Server
To fix some issues with importing a backup from Jira Cloud into Jira Server, we needed to change the database column size. As a result, Jira might start up a bit slower just after upgrade, especially if you are using MySQL database. On the upside, the migration process finishes with no exceptions.
データベース パスワードの暗号化
You can now encrypt your database password that is stored in the dbconfig.xml file. We've prepared two encryption methods for basic and advanced users, and also a way to create your own Cipher. For more information, see Encrypting database password.
Cluster lock mechanism improved in Data Center
We improved the cluster lock mechanism in Jira DC by introducing lock timeouts. Now, when a node loses a cluster lock it will be automatically recoverable without any actions from administrator. Previously this situation could only be resolved by restarting the node. You can read more about this issue here.
サポート終了のお知らせ
In Jira 8.3, we're making the following changes:
事前告知: 一部の組み込みインポーターのサポートを終了。Jira 8.4 では、Asana、Bugzilla、Pivotal Tracker などの特定のアプリケーション専用の組み込みのインポーターのサポートを廃止します。CSV または JSON の各形式を使用して、引き続き Jira にデータをインポートできるようになります。
- Removed Jira CDN dark feature
The unsupported Jira CDN dark featurejira.fixed.cdn.enableand system propertyjira.fixed.cdn.prefixhas been removed in Jira 8.4. We recommend you turn off this dark feature, and remove the system property from yoursetenv.shorsetenv.batfile.
