By working with versions you will be able to get a more detailed view of your project for a specific time range. Since you can assign your issues to a version, you can also easily track in which version/build a specific issue was found in and in which version/build the issue was completed.
If you use resource management, you can also see summaries for time and costs for the version, as well as how many hours users are assigned to work on the version.
For a version you can get the same information as for the whole project. Please refer to the text about how to manage projects, to find information on graphs and other information that is available.
By using the Estimated time and Remaining time fields on issue you can always see how healty your project is. You can easily edit estimated times and remaining times for issues included in a version and get an updated Burn-down chart.
Automatically created release notes when an issue has been completed. The text that you fill in as release text for each issue in the version will automatically be put together as release notes for that release.
