This page is to be included into all our Milestone release notes for the Confluence 3.0 release cycle

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 public development release ("Milestone") leading up to Confluence 3.0, which will be probably shipped in mid-Q2/2009. 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?

Development Releases are Not Safe

Development releases are snapshots of the ongoing Confluence development process. As such:

  • 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 DRs, or from any DR to the eventual final release. So it's possible that you won't be able to migrate any data you store in a Confluence DR to a future Confluence release.

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 all of our milestone releases even have been 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 2.10.x to this release. We strongly recommend that you backup your confluence-home directory and database before upgrading!
