As the next step of a project that will continue for some time, the following Harlequin Core content is available to you alongside the v13.2 release:

  • Extensions Manual
  • API Reference Manual
  • SDK Developer’s Guide

In addition to updating any technical content and formatting, we will amend any invalid hyperlinks as we update and publish the remaining Harlequin Core documents (including Harlequin Core Technical Notes).

If you find something that doesn’t look right, please email

This is the root page for the first Confluence version of the SDK manual.
