Glimmer DSL for Web (Ruby-in-the-Browser Web Frontend Framework) version 0.6.1 has been relased with support for Component Custom Event Listeners. For example, an accordion component can signal when accordion sections are expanded or collapsed, and consumers can listen to those events and perform some actions accordingly.
