This page tries to list and explain all available Ubuntu Touch channels that have been currently set-up. Please remember that this information can get quickly out-of-date. All the refactored channels follow the schema specified in Touch/ChannelSchemaSpec - please read this document to understand the rationale for the following setup.
Current Channel List

Manually promoted images from ubuntu-touch/rc-proposed/*. An image from this channel once per month gets promoted to the stable channel as the new official OTA.
