Introducing XL Release 4.7.0


XebiaLabs Support -

Dear XebiaLabs community,

We are pleased to announce the release of XL Release 4.7.0. In this major version:

  • The release archiving feature has been introduced to improve performance
  • Two new ways to extend XL Release have been introduced
  • XL Release has been upgraded for the newest versions of Jython and Spring Security


Download the release at the XebiaLabs Software Distribution site.

Automatically archive completed and aborted releases

XL Release can now automatically archive 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: By default, all releases are archived immediately as soon as the server is started after upgrading to 4.7.0. For information about changing this to a longer period, 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.

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 has also been upgraded from using Spring Security version 3.2.5 to 4.0.1. Please refer to Migrate to XL Release 4.7.0 for more information.
