Release Notes 2.10-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 2.10 ("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?
Development releases are not production ready. Development releases are snapshots of the ongoing Confluence development process. While we try to keep these releases stable, they have not undergone the same degree of testing as a full release, and could contain features that are 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 a final release. You may 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!

Issues resolved or improved in this release
"Did you mean?"
Dave Loeng's auto-suggest feature is the first major 20%-project to make it into Confluence. Try it out by mistyping a search, and you will find a link suggesting more relevant searches. This is an actual example of me typing way too fast: 
Try misspelling someone's difficult surname, like say, 'fraggemnan'.
User management
Confluence Hosted developer Jens Schumacher has been very busy hacking on Confluence again, this time he improved the user-management a lot - so much more convenient than before.
- Improved Search
- Adding and removing users when viewing a group
- New table styles
- Improved User Picker
Avatar cropping and deletion
Another, smaller 20%-project also made it into this release: Charles Miller and Dmitry baranovskiy enabled Confluence to allow cropping of uploaded avatar-images, and while they were at it the highly desired "delete images you never intended to upload in the first place" issue got solved too in order to make another 23 voters happy.
Backend changes
The Engine Room team has implemented several important backend changes in this milestone:
- Integrated the first version of Plugins 2.0, including an initial migration the Confluence plugin repository to Plugins 2. An updated version of this plugin and a converted dynamictasklist are planned for the next milestone.
- Trusted authentication and other Seraph-based authentication methods are now available for calls to the Confluence RPC methods (Release Notes 2.10-m2 ("Milestone 2")). This makes it practical to write Confluence gadgets which use the remote API to retrieve data. Tom Davies is using this to implement his Crucible Confluence review plugin.
