Changed

Redesigned almost the entire site with a focus on mobile/tablet accessibility and addressing common UX complaints
Content pages are now entwined with their related discussion boards, making it easy to flip between e.g. characters and discussions about characters.
Recolored Religions from yellow to indigo to make all religion-related things easier to read.
Changelogs have been moved to a separate tab that doesn't expand when clicking the "expand all" button on content pages.
Document editor has been redesigned.
Toasts are now temporarily shown (instead of permanent on the page) and many actions have had toast messages improved/added.
Rather than picking 5 random fields to show in the quick reference tab of prompts, all fields with a value are now shown in an accordion view.

Fixed

The sidebar can now be toggled visible or not on mobile and tablet devices.
Uploaded images are no longer weirdly squished when shown on the dashboard.
Icons should no longer overlap in the navbar on mobile.
Fixed and re-enabled the quick-reference tab on the serendipitous content prompts.
The page to toggle content pages on/off has been redesigned and now works in Internet Explorer.
The sidebar now properly scrolls in Internet Explorer on small screens.
Focusing/scoping to a universe now properly automatically suggests all new content be added to that universe.

Added a half-dozen profile fields.
Documents can now be viewed also (instead of always just edited).
Added quick-access links to documents, discussions, prompts, and your profile from the dashboard.
Pages can now dictate their own colors and actions, making each section of the site feel like its own product to be improved.
Enabled the quick-create FAB on the forums (and moved the Currently Online list to accommodate).
