Release Notes 2.10-m1 ("Milestone 1")

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 2.10 ("Two Ten"). This is a public development release (DR) leading up to Confluence 2.10. 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 2.9.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

It's all about small improvements this time.

During thhe last weeks we have fixed a whole bunch of bugs, worked on major functionality, and done a lot of planning. Therefore the M1 is a rather small release - it contains the bugfixes, but no major work yet. We have developed a new feature and two great smaller improvements which are almost done, but didn't make it into this Milestone, so expect a lot more in M2 in two weeks.

But wait, there is one small new feature that might have a big impact on EAC. Jens Schumacher, developer on Confluence Hosted, has been working on a top secret mission, and his new feature means you now can store CSS per space and for the whole installation.

Inside Atlassian we now have a small competition going with developers competing for the nicest/coolest/weirdest CSS-based design to be delivered within the next two weeks.

The competition only started yesterday, but there are some funky screenshots available already (smile) Obviously Confluence still has areas that are completely hardwired and not stylable yet, but we are working on this as we go.
