The \"dev\" branch is the one where all contributions will be merged. If you plan to propose a patch, please commit into the \"dev\" branch. Direct commit to \"master\" are not permitted. Feature branches will also exist, typically to introduce new requirements, and be temporarily available for testing before merge into \"dev\" branch.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdavideuler%2Fxxhash","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fdavideuler%2Fxxhash","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fdavideuler%2Fxxhash/lists"}
