Confluence 7.0 アップグレード ノート

以下は、Confluence 7.0 にアップグレードする際の重要な注意事項です。このリリースの新機能と改善点の詳細については、「Confluence 7.0 リリース ノート」を参照してください。 

On this page:

Synchrony data will be removed during the upgrade

We've added two new scheduled jobs to help you regularly evict data from the Synchrony database tables. These tables have grown very large for most customers, so when you upgrade to Confluence 7.0, an upgrade task will truncate these tables. Many customers have already been manually truncating these tables as a workaround.

The upgrade task could take some time to run. On our test site (classified as Large) it took about 30 minutes. 

Page edits that are in-progress may be deleted by this process if the changes have not been published, auto-saved as a draft, or were abandoned (for example if the user’s browser crashed while editing). Because Confluence auto-saves a draft every 30 seconds by default, the loss should be minimal. The auto-save interval is configurable, so you might want to check what it's set to in your site when planning your upgrade.

CDN dark feature removed

The unsupported Confluence CDN dark feature conlfuence.fixed.cdn.enabled has been removed. If you relied on this dark feature, you should remove it from your or setenv.bat file.  


The new pre-upgrade planning tool is provided by the Troubleshooting and Support tools app, which is bundled with Confluence. To ensure the tool displays the latest Confluence version info, it needs to be able to access

If a connection can’t be established, for example if your firewall or proxy server blocks this URL, the tool won’t be able to fetch any updates to version data, supported platforms or documentation. It will instead list Confluence versions that were available when Troubleshooting and Support tools app was last updated.

If you don't want to allow this URL you can instead go to  > Manage apps and update the Troubleshooting and Support tools app before you use the tool. 

Also, the version of the Troubleshooting and Support tools app bundled with Confluence 7.0 does not have a Data Center UI, but an updated version is already available from Marketplace that provides Data Center support.

If you're running Confluence 6.5 or later, we recommend updating the Troubleshooting and Support tools app before you upgrade, so you can use the tool to plan your upgrade to 7.0. 

Post-upgrade report

After successfully upgrading Confluence, you'll now be directed to a new upgrade report page, which shows the status of your apps and application links, and highlights any important changes that may impact your systems or users.

You can also access the report at any time from  > General Configuration > Latest upgrade report.

Changes to thumbnail and preview generation

When you insert an uploaded file into a page, Confluence generates thumbnail images of the file contents so it can be viewed inline in the page, or in the preview. Some types of files can be very memory intensive, so we've added guard rails to protect the stability of your site when people upload files.

  • We no longer generate thumbnails for TIFF or PSD (Photoshop) files. These files are often very large, and have been known to cause out of memory errors. You can choose to turn this back on using the confluence.document.conversion.imaging.enabled.tif or confluence.document.conversion.imaging.enabled.psd and system properties.
  • We've added a time limit of 30 seconds when generating thumbnails for image files and presentation files (such as Powerpoint files). This is to prevent out of memory errors affecting your entire site. You can increase the timeout using the confluence.document.conversion.imaging.convert.timeout and confluence.document.conversion.slides.convert.timeout system properties. 

The default values for these properties apply in both Server and Data Center, but the method you'll use to change the values differs if you are using Data Center, due to the way document conversion is handled by the external process pool. See Document conversion for Confluence Data Center for more information.  

Atlassian User Interface (AUI) 8 upgrade

We've upgraded our frontend library, AUI, from 7.9.7 to 8.3.4. The look and feel of Confluence is the same, but you'll notice a few small visual changes to message flags and the app switcher icon.

Trackback and referrers removed

We have removed the trackback and referrers features. An upgrade task will delete the the TRACKBACKLINKS and EXTRNLNKS database tables.

We recommend you back up the data prior to upgrading if you want to keep the historical data. 

License Details screen changes

We've made some minor wording changes to the license screen to make it easier to understand, and more consistent with other Atlassian applications. For example 'Support period' is now called 'Maintenance expiry', but the functionality remains the same. 

Change to how you configure your mail server in the Confluence distribution

If you set up your mail server in the Confluence distribution (in the server.xml file) rather than through the UI, there are now two additional jar files that you'll need to move from <confluence-install>\confluence\WEB-INF\lib to <confluence-install>\lib

  • javax.activation-x.x.x.jar
  • javax.activation-api-1.2.0.jar 

See Setting Up a Mail Session for the Confluence Distribution for the full guide. 

There's a known issue with JavaMail 1.6.2 that affects the ability to define alternate email providers. See CONFSERVER-59040 - Getting issue details... STATUS . This is resolved in Confluence 7.5. 

HipChat Server and Data Center integration

The Hipchat plugins are now disabled for all new installations. If you're upgrading Confluence and don't use Hipchat, you can disable the following system apps, which will hide all Hipchat integration options. 

  • Atlassian Hipchat integration plugin
  • Atlassian Hipchat integration plugin core
  • Confluence Hipchat emoticons plugin
  • Confluence Hipchat integrations plugin
  • Confluence Hipchat plugin

You can continue to use the Hipchat integration until Hipchat Server and Data Center reach end of life. 

Edit in Office workaround is not available

In Confluence 6.15.6 (backported to the 6.13.6 Enterprise Release) we provided a workaround for customers who are unable to use Companion app, so you could continue to use Edit in Office.

This workaround is not available in Confluence 7.0, so the dark feature flag will have no effect. 

Ultimate Permission Manager app requires an update

As you may be aware, we acquired the Ultimate Permission Manager app a few months ago, and plan to incorporate the functionality into Confluence Data Center in a future 7.x version.  

If you're already using the Ultimate Permission Manager, you'll need to manually update to the latest version of the app to use it with Confluence 7.0. 

See Ultimate Permission Manager Release Notes for a link to the updated file, and instructions on how to update this app manually.  

Confluence Source Editor

The Atlassian Labs Confluence Source Editor app is not yet compatible with Confluence 7.0. We hope to update this app in the near future. If you rely heavily on this app, you may want to wait until a compatible version is available on Marketplace before you upgrade.

Update  : a new version of the Confluence Source Editor is now available on Marketplace. This version is compatible with Confluence 7.0. 

6.3 以前からのアップグレード

Confluence 6.3 以前からアップグレードする場合、スペース ディレクトリにスペースが表示されない既知の課題があります。これを修正するには、アップグレード後にサイトを再インデックスする 必要があります。 


No changes to supported platforms in this release. 

Advance notice: Java 11 support

We'll be adding support for Java 11 in a future 7.x release. We chose Java 11 because, as a Long Term Support version, it will set you up for several years of access to regular bug fixes and security updates.


Confluence 7.0 is a platform release, and contains a number of breaking changes, for example where we have removed a feature, screen, or API.

Head to  Preparing for Confluence 7.0  to find out more about changes under the hood.
