* JENKINS-28732: Add support to the script security plug-in to Active Choices
This issue is related to security, and will change the way your scripts are evaluated in Jenkins. Right now parameters can execute any kind of code, regardless of how dangerous that code can be.
With the script-security-plugin integration, some of these scripts can be sandboxed, allowing only approved scripts to be executed.
Please, do not install this version in production. Use a test bed server, and, preferably, use a real set of jobs, as the migration from 1.4 to 1.5 is one of the most important tests for this issue.
