This release is a preview of the Shared Project feature which will be part of the Version 5.0 scheduled for Q1 2008. We are looking for early feedback on this feature, but as an alpha release, some bugs should be expected.
The Shared Projects feature enables multiple people to work on the same Axure RP project at the same time. It also maintains a history of revisions to the project.

For this preview, we recommend limiting shared projects to 300 combined pages and masters and up to five people working on a project.
Other features in this preview include:
- Scroll to Image Map Region (Anchors)
- Moving Dynamic Panels
- OnFocus and OnLostFocus events
More information and the download are available here.

This preview can be installed without uninstalling previous versions, but please note that files created in the Shared Projects Feature Preview will not open in previous versions of Axure RP. Files created in earlier versions will be converted to the new format.
If you have a license key that is valid for 4.6, you can use this preview without interruption. If you do not have a current license key, the preview will provide you with a 30 day evaluation.
Will this be a free update? Version 5.0 will be a free update for customers who purchased a license or a maintenance renewal for Axure RP Pro within 12 months of that release. Other customers will need to purchase a renewal before upgrading.
Please report any issues you might find to support@axure.com or in the forums.
