Release Notes 3.0-m4 ("Milestone 4")

Milestone release advisory

For testing use only

Do not use this release to upgrade your production systems.

This release is a public development release ('milestone') leading up to the next Confluence major release. Development releases are a snapshot of our work in progress, allowing our customers and especially plugin developers to see what we're up to.

Who should upgrade?

Please note the following

  • Development releases are not safe. Development releases are snapshots of the ongoing Confluence development process. For that reason:
    • While we try to keep these releases stable, they have not undergone the same degree of testing as a full release.
    • Features in development releases may be incomplete, or may change or be removed before the next full release.
  • No upgrade path. Because development releases represent work in progress, we cannot provide a supported upgrade path between development releases, or from any development release to the eventual final release. Thus, it is possible that you will not be able to migrate any data you store in a Confluence development release to a future Confluence release.
  • Atlassian does not provide support for development releases.

In supplying milestone releases, our aim is to provide plugin developers with an opportunity to see the latest changes in the code.

Each milestone release has passed all our automatic tests and has been used for one week on our official internal Confluence server. Most of the issues solved have been reviewed too, and all of our milestone releases even have been performance tested for a while.

However, since our milestones releases are timeboxed (that is, they are released every two weeks, no matter how far we have come implementing features and bugfixes) there is always a chance that we have new known bugs that are scheduled to be fixed in the next milestone, or completely new bugs unknown even to us.

Additionally, we have not completed our performance testing and compatibility testing for all supported databases and user management systems. So, for example, a milestone release may behave well on a small installation but show severe problems when subjected to many users.

Upgrade Procedure

Follow the normal upgrade instructions to upgrade your test instance to this release. We strongly recommend that you backup your Confluence home directory and database before upgrading!


All development releases are available from the development releases page on the Atlassian website.

Issues resolved or improved in this milestone since Confluence 3.0 Milestone 3

Experimental Macro Browser

The Macro Browser is now available in the wiki markup editor, however it is currently not in a state for proper use. It is quite buggy and has been included for QA and the dev team, so please do not raise any issues against it yet.


User Hover Fixes

A lot of outstanding issues with User Hover were fixed for m4.

First Cut of User Profiles

The profile tabs have been rearranged into a more intuitive order, with general and email preferences moved to a separate "Settings" tab:

Additional fields have now been added to your user profile.

Performance Improvements

We did the following small performance improvements:

Although the performance improvement hasn't been as dramatically as in M2, but we still see a solid trend towards shorter and less varying response times. The overall performance improvement is around 10%-15% with more to come in the next milestones.

Known issues

  • Performance issues with frequently updated attachments. One of the performance tweaks in M4 can cause issues if you have attachments with thousands of versions. (Release Notes 3.0-m4 ("Milestone 4"))
  • The Macro Browser is very fresh and contains many bugs.
