[stevie-]

npm error Conflicting peer dependency: semantic-release@19.0.5
npm error node_modules/semantic-release
npm error   peer semantic-release@">=16.0.0 < 20" from semantic-release-github-pr@6.0.3
npm error   node_modules/semantic-release-github-pr
npm error     dev semantic-release-github-pr@"*" from the root project

currently using semantic-release@24.2.0

Is this an option and how fast can this be implemented?
