    Version 4.7.0

    Automatically archive completed and aborted releases

    XL Release now archives completed and aborted releases older than a configurable amount of time. This improves performance and makes the repository faster and more efficient.

    Archived releases appear in reports such as the release automation report and the release value stream report. You cannot modify archived releases, but you can download any files that are attached to them.

    You can configure the duration after which XL Release will archive a completed release in the general settings.

    Important: For important information about how archiving works immediately after you upgrade to XL Release 4.7.0, refer to the version-specific upgrade notes.

    The archiving feature replaces the purging feature that was introduced in XL Release 4.6.0. Purging is no longer available in XL Release.

    Note: Starting with XL Release 4.7.0, all reports only show the data of archived releases (except the releases at risk report). For example, if you configuring archiving so that releases are archived 7 days after completion, releases that were completed in past 6 days will not be taken into account in reports.

    For information about moving the database where XL Release stores archived releases, refer to Configure the reporting database.

    Support Jython-based export hooks

    XL Release now supports hooks that you can use to export information about completed releases to an external reporting database. Export hooks are written in Jython and can be added to XL Release as a JAR file or by placing files in the XL Release classpath.

    You can define export hooks in two ways: generic export hooks that you can use to export information to any type of storage, and JDBC export hooks that can export data to an SQL database.

    A sample export hook implementation is available on GitHub.

    Upgraded Jython and Spring Security

    XL Release has been upgraded from using Jython version 2.5 to 2.7 and from using Spring Security version 3.2.5 to 4.0.1. For information about these upgrades, refer to the version-specific upgrade notes.

    Restart a phase from a specific task

    You can now restart a phase in a running release, either from the beginning of the phase or from a specific task in the phase.

    When you restart a phase, the release is automatically paused, and you can choose whether to resume it right away or to wait until later. This gives you the opportunity to update variables, change task assignees, adjust due dates, and make any other changes that are needed.

    Automatically purge completed and aborted releases

    XL Release can now automatically purge completed and aborted releases that are older than a configurable amount of time. This improves performance when you have many completed and aborted releases.
