Students working on UCOSP or Open Academy are encouraged to have a presence in IRC 24/7, in order to be able to ask us questions, see our (possibly delayed) answers to other questions, and to generally see all other discussions taking place.
See the Sonar project page for a detailed description. Basically Review Board has always had the ability for Extensions (or even the core) to add additional fields to a review request, for example for a company to track internal metadata. Unfortunately, these fields have always been limited to text or markdown. This project will be adding support for other field types like checkboxes, date selectors, dropdowns, and even custom fields defined by an ExtensionHook.
This is an architectural change for Review Board 2.6 that affects extensions. Currently, there are some default review request actions (like "Close -> Submitted" or "Download Diff" or "Ship It!") that have been hardcoded into the template. Extensions can provide custom actions by passing dictionaries into a variety of `ActionHooks`.
