We did a similar change in commit 47925fbab, and we were getting a
warning in Rails 6.0:
DEPRECATION WARNING: render file: should be given the absolute path to a
file
Since using `render file:` would ignore views in custom folders, we're
using `render template:` instead.
Using the `_html` suffix in an i18n key is the same as using `html_safe`
on it, which means that translation could potentially be used for XSS
attacks.
Dashboard routes have been refactored. Now instead of having resources
for dashboard and routes inside a dashboard namespace the proposal
routes contain a dashboar singleton containing everything related to it.
