Changes to features for Confluence (22 March 2022)

We will remove the Usage Stats plugin in Confluence 8.0.

The Confluence Usage Stats plugin provides basic page view tracking in Confluence Server. We know that usage tracking is important to you, however the current implementation has long been disabled by default as it can have a noticeable impact on your site's performance.

Significant work is required to make this feature compatible with Confluence 8.0, and the functionality is largely superseded by Analytics, which was added in Confluence Data Center 7.11.

Analytics provides a significantly better analytics experience, and will continue to be available for Data Center customers in Confluence 8.0.

Deprecated browsers for Confluence (2 February 2021)

In January 2020 Microsoft released a new Microsoft Edge browser based on Chromium. This new version is compatible with all supported Windows versions, and replaces the previous version, now known as Microsoft Edge Legacy. Read more about the difference between the new Microsoft Edge and Microsoft Edge Legacy on the Microsoft support site. 

As Microsoft have announced plans to end support for Microsoft Edge Legacy, we have also decided to end support for Microsoft Edge Legacy. 

End of support means we will not fix bugs specific to Microsoft Edge Legacy, and will begin to introduce features that aren't compatible with this browser.

When is this happening?

• Confluence 7.12 is the last version to support Microsoft Edge Legacy. 
• Confluence 7.13 and subsequent versions will not support Microsoft Edge Legacy.  

What this means for you

We recommend switching to one of our supported browsers, such as the new Microsoft Edge (Chromium), Google Chrome, or Mozilla Firefox.

In 2015 Microsoft released Edge as the browser to supersede Internet Explorer, and in recent times Microsoft has discouraged the use of Internet Explorer as a default browser.

Deprecated macros for Confluence (12 March 2019)

We will end support for the following macros in Confluence 7.0, and hide them from the macro browser. Any existing instances of these macros will still work, but you won't be able to insert these macros into the editor using the macro browser: 

• IM Presence macro
• Netwok macro
• Search results macro
• Space details macro

End of support means Atlassian will not fix bugs related to these macros in Confluence 7.0 or later versions. We will remove these macro entirely in a future Confluence release, and will provide more information at that time.

To check whether a macro is used in your site, go to   > General Configuration  > Macro Usage. Some macros will be listed under the system app that provides them. 

IM Presence macro

The IM Presence Macro shows when a given user is online in a selected chat service. The macro only supports a small number of chat services, and we feel that most modern chat tools provide better ways to see this information.

If you have questions or concerns, please comment on this issue  CONFSERVER-57596 - Getting issue details... STATUS .

Network macro

The Network Macro allows you display the people a particular user is following, or people who are following that user. Following someone is a useful way to get notifications about their activity, and this network information is also available on each user's profile page.

If you have questions or concerns, please comment on this issue  CONFSERVER-57597 - Getting issue details... STATUS .

Search results macro

The Search Results Macro allows you to display the results of a keyword search on a page. We are making some great changes to Search over the next few releases, and have observed that this macro is rarely used.

If you have questions or concerns, please comment on this issue  CONFSERVER-57598 - Getting issue details... STATUS .

Space details macro

The Space Details Macro allows you to display basic information about the current space on a page. This information is available at all times from Space Tools > Overview.

If you have questions or concerns, please comment on this issue  CONFSERVER-57599 - Getting issue details... STATUS . 

Deprecated Gadgets in Confluence (12 March 2019)

We will end support for the following Gadgets in Confluence 7.0, and hide them from the macro browser. Any existing instances of these gadgets will still work, but you won't be able to insert these gadgets into the editor using the macro browser:

• Activity Stream
• Confluence Page Gadget
• Confluence Quick Nav Gadget
• News gadget

End of support means Atlassian will not fix bugs related to these gadgets in Confluence 7.0 or later versions. We will remove these gadgets entirely in a future Confluence release, and will provide more information at that time.

Gadgets were designed to allow you to display information dynamically from sources like iGoogle or Jira, for example, in Confluence. The first gadgets were introduced in Confluence 3.1, and much of the technology they were based on is now superseded or obsolete. Since then we have also implemented a number of better ways to display dynamic information using macros and other integration points.

Activity Stream gadget

The Activity stream gadget shows a list of recently changed content in your site. We recommend using the Recently Updated macro as an alternative in Confluence. 

Confluence Page Gadget

This gadget displays the contents of a Confluence page. We recommend using the Include Page macro as an alternative in Confluence.  

Confluence Quick Nav Gadget

This gadget provides a search field that can be used to search for page titles in Confluence. We recommend using the Livesearch macro as an alternative in Confluence. 

News gadget

This gadget previously displayed blogs and other news from Atlassian. It has not been displaying content for some time. We will remove this gadget completley in 7.0.  

If you have questions or concerns, please comment on this issue  CONFSERVER-57614 - Getting issue details... STATUS .

Changes to features in Confluence (12 March 2019)

Shortcut links

Shortcut Links were introduced in Confluence 2.3 and provided a quick way to add links to websites in wiki markup. Shortcut links can only be configured by an administrator, are not easily discoverable, and seldom used by end users.

Trackback and external referrers

We will remove the trackback and referrers features completley in Confluence 7.0.

Trackback enables Confluence to send and receive trackback pings when pages are linked to. External Referrers appear on the Page Information view of a page, and list clicks from external websites to the page. Trackback is no longer widely used in modern websites, and because it relies on accepting unauthenticated requests to a particular URL, is a spam vector.

If you have questions or concerns, please comment on this issue  CONFSERVER-57611 - Getting issue details... STATUS .

Orphaned pages screen

We will remove the Orphaned pages screen in the default theme in Confluence 7.0.

The Orphaned pages screen provided a list of all pages that Confluence considers orphaned pages (not a child of a space homepage, and not linked to by any other page). Since the introduction of the Confluence 5 default theme, the orphaned pages screen has been less useful because it's always possible to see all pages in a space via Space Tools > Reorder pages.

If you have questions or concerns, please comment on this issue  CONFSERVER-57601 - Getting issue details... STATUS .

Hipchat integration

We have discontinued development on all chat products. Hipchat Cloud services were shut down in February 2019, and Hipchat Data Center and Server will both reach end of life within the next year.

We will end support for all bundled Hipchat plugins in Confluence 7.0. These will be disabled by default for new installations. This will have no impact on existing installations, and can be easily enabled if required.

End of support means that Atlassian will not fix bugs related to Hipchat integration in Confluence 7.0 or later versions. 

If you have questions or concerns, please comment on this issue  CONFSERVER-57602 - Getting issue details... STATUS .

Deprecated databases for Confluence (2 October 2018)

We will end support for the JUnit Report macro with the release of Confluence 6.6. This macro is used to display the results of JUnit tests on a Confluence page and, based on our research, is rarely used.

End of support means that Atlassian will not fix bugs related to this macro past the support end date for your version of Confluence. We will remove this macro entirely in a future Confluence release, and will provide more information at that time.

To check whether this macro is used in your site, go to Administration  > General Configuration > Macro Usage. The JUnit Report macro will be listed under Advanced Macros if it's used.

If you have questions or concerns, please comment on this issue CONFSERVER-53942 - Getting issue details... STATUS .

Deprecated driver for Microsoft SQL Server

We are replacing the open source jTDS driver for SQL Server with the official Microsoft JDBC Driver for SQL Server. This new driver is bundled with Confluence 6.4 and later.

Atlassian will end support for the jTDS driver in Confluence 6.6. End of support means that Atlassian will not offer support for, or fix bugs related to, installing and running Confluence 6.6 or later with this driver.

• Confluence 6.5.x will be the last major release to bundle the jTDS driver.

Atlassian will end support for the default browser provided with Android 4.0.3 (Ice Cream Sandwich) in Confluence 6.0. End of support means that Atlassian will not fix bugs related to this browser past the support end date, except for security related issues. This means:

• Confluence 5.10 will be the last major release that supports the default browser provided with Android 4.0.3 (Ice Cream Sandwich).
• Confluence 5.10.x and earlier versions will continue to work on the default browser provided with Android 4.0.3 (Ice Cream Sandwich).

If you have questions or concerns regarding this announcement, please email eol-announcement at atlassian dot com.

Changes to Confluence distributions (8 June 2016)

To help us bring you new Confluence Server releases faster, we are considering only providing 64-bit installers.  Confluence 5.10 would be the last Confluence release to provide a 32-bit installer. 

Q: Can I upgrade using the 64-bit installer?

Yes. If you installed Confluence using the 32-bit installer on a 64-bit operating system, you will be able to upgrade using the 64-bit installer.

Discontinued features for Confluence (10 July 2015)

Status updates

As part of our work to make Confluence simpler and easier to use we've decided to remove the Status Updates feature in Confluence 5.9. This includes the ability to:

• update your status
• see other people's status via their profile or the User Status List macro.

Our research tells us that this feature isn't widely used, and we believe that HipChat gives your team much better ways to share their status.

We'll provide more information at the time of the Confluence 5.9 release. If you have questions or concerns, please comment on this issue  CONF-38253 - Getting issue details... STATUS .

Documentation theme

In order to better focus our development efforts on a single theme, we plan to remove the Documentation theme in Confluence 6.0.

We know that many customers use the Documentation theme because they like to have a page tree in their space sidebar. This has been available in the default theme for some time now, plus other great features like sidebar shortcuts, JIRA links, and sticky table headers.

To help you switch to the more modern default theme, we've added some of your favorite documentation theme features, including the ability to add:

• a header and footer
• custom content to the sidebar.

These new additions to the default theme are available in Confluence 5.9. As these fields will continue to use wiki markup, you will be able to drop your existing wiki markup straight from the Documentation theme into the default theme.

To help you switch themes we've put together a FAQ and step-by-step guide  which covers everything from how to turn on the default theme, find out which spaces are using the theme, and what to do if the Documentation theme is the global theme for your whole site. 

If you have any questions or concerns please comment on this issue  CONF-38256 - Getting issue details... STATUS .

Deprecated Java platform for Confluence (27 January 2015)

Deprecated distribution for Confluence (2 September 2014)

To help us to make Confluence a more robust and scalable application, we have decided to stop providing an EAR/WAR distribution. This means that the only supported application server will be the version of Tomcat that is bundled with each release.

Confluence 5.6 will be the last Confluence release to provide an EAR/WAR edition. 

Q: Do I need to use the installer?
No, the removal of the EAR/WAR distribution does not force you to use the installer. You can still use the standalone distribution, which doesn't have an install script - it's just a copy of Tomcat with Confluence configured inside it. Essentially it's a directory that you unpack and then run yourself. 

Q: What if a security problem is found in the bundled version of Tomcat?
Our security team monitors vulnerabilities in all our dependencies, including Tomcat, and fixes continue to follow our Security Bugfix Policy. If at any time you become aware of a vulnerability we've missed, please report it as described in How to report a security issue.

To allow us to dedicate resources to providing the best experience on modern browsers, Confluence 5.5 will be the last release that supports Internet Explorer 8 (IE8). The reasons behind this decision are to enable us to provide the best user experience to our customers, accelerate our pace of innovation and give us the ability to utilize modern browser technologies.

End of support means that Atlassian will not perform any maintenance on Confluence related to IE8 after the final release of Confluence 5.5.x, except for security related issues. In order to minimize the impact on you and the way your company uses Confluence, we have provided this announcement as early as possible, and hope that the subsequent 6 month period will give you adequate time to prepare for this change without disruption.

Atlassian will continue to support Internet Explorer 9 (IE9) and Internet Explorer 10 (IE10) as well as the latest versions of Chrome, Firefox and Safari. For further information, please refer to the Supported Platforms page. If you have questions or concerns regarding this announcement, please email eol-announcement at atlassian dot com.
