Since 1.2.0:

• The Jenkins launcher is replaced with Gearman launcher. An internal Gearman server is provided, and there is a Gearman plugin for Jenkins, so migration to the new system should be fairly straightforward. See the Launchers section of the documentation for details.
• The custom parameter function signature now takes a QueueItem as the first argument, rather than the Change. The QueueItem has the full context for why the change is being run (including the pipeline, items ahead and behind, etc.). The Change is still available via the "change" attribute on the QueueItem.
