+- Adds support for the new [GitHub Job summaries](https://github.blog/2022-05-09-supercharging-github-actions-with-job-summaries/) API via:
+ - `danger.github.setSummaryMarkdown("[markdown]")` for the JavaScript DSL
+ - The results DSL for sub-processes now accepts `{ github: { stepSummary: "[markdown]" } }` from projects the Swift and Kotlin implementations of Danger.
+
+ This gives you the chance to leave feedback on the overview page for a PR, it won't ping people
+ in the PR thread or trigger emails which is why it's a separate attribute in the DSL. Potentially open to having the main
+ comment in the job summary if someone can make a good case for it in the Danger JS issues. [@orta]
+
