Release Notes 2.9-m2 ("Milestone 2")

Do not use this release to upgrade your production systems.

For all production use and testing of Confluence, please use the latest official release.
This release is a milestone development release for 2.9. This is a public development release (DR) leading up to Confluence 2.9. 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.

Our milestone releases aim 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 usually milestone releases even have been load- and performance-tested for a while.

However, since our milestones releases are timeboxed (i.e. they get 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, which are scheduled to be fixed in the next milestone, or completely new bugs unknown even to us.

Additionally, our performance-testing and compatibility testing for databases and application servers is not done to the full extent. So, for example, a milestone release might behave well on a small installation but show severe problems when subjected to many users.

Upgrade Procedure

Follow the normal upgrade instructions to upgrade from Confluence 2.8.x to this release. We strongly recommend that you backup your confluence-home directory and database before upgrading!


All development releases are available from Development Releases on the Atlassian website.

Issues resolved or improved in this release

Page Ordering: We have been improving the page-tree a bit, fitting in some work that was intended for Confluence 2.8 but didn't make it. The tree now has a "revert to alphabetical mode" button which will revert manually ordered nodes back to the original alphanumeric ordering. Additionally we added one small improvement which will help to battle spam: administrators will see two additional buttons on the page tree that enable easy deletion and preview of pages. We are not entirely sure yet whether (and how) these two buttons will ship, so don't raise improvement issues for those two buttons yet. (IF they ship with 2.9, then we will put in some more polish of course)

Unfortunately there are a few known (uncritical) bugs related to the revert-to-alphabetic-mode in edge-cases, which will be addressed by M3.

Search: The Search has improved internally (the ranking should be a bit more relevant than before), and also what is being searched has changed: mail and personal spaces are searched by default, and using the space key in the search boosts hits within that space.

Known problems

Some small issues, mainly with the UI, but nothing serious.
