refs #9601 - refactor architecture of routing so you can define a channel - a channel is a different way of looking at your posts (a view) - a channel does not change the url of a resource Example channel ``` routes: /worldcup-2018-russia/: controller: channel filter: tag:football18 data: tag.football18 ``` - added ability to redirect resources to a channel/static route - support templates for channels - ensure we still support static routes (e.g. /about/: home) - ensure pagination + rss works out of the box
