# Currently, Semaphore 2.0 only supports GitHub, while Semaphore Classic
# supports Bitbucket too. The payload does not have URLs for commits, tags,
# pull requests, etc. So, we use separate templates for GitHub and construct
# the URLs ourselves. For any other repository hosting services we use
# templates that don't have any links in them.
