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?
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.
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.
