-The pull request process differs for new features and bugs. Before sending a pull request for a new feature, you should first create an issue with `[Proposal]` in the title. The proposal should describe the new feature, as well as implementation ideas. The proposal will then be reviewed and either approved or denied. Once a proposal is approved, a pull request may be created implementing the new feature. Pull requests which do not follow this guideline will be closed immediately.
