+
+This change drops support for deprecated location types which have all been replaced by the `url` type.
+There has been a deprecation warning in place since the beginning of this year so most should already be migrated and received information at this point.
+
+The now removed location types are:
+
+```
+github
+github/api
+bitbucket/api
+gitlab/api
+azure/api
+```
