# GitHub Changed (default) Base Branch from "master" to "main"

### Issue <a href="#issue" id="issue"></a>

[As of Oct 1st, 2020, Github has changed their (default) base branches from "master" to "main"](https://github.com/github/renaming) . Any new repos created by users will now use "main" as the (default) base branch.**Existing repos are unaffected.**

Artifacts and dinghyfiles coming from GitHub will need to be adjusted by adding additional configuration, until updates to Spinnaker are released to accommodate these changes.
