 in the [announcement]({% link blog/_posts/2022-07-13-scala-improvement-process-reloaded.md %}), the main changes of
 the new process are the following. First, the proposals are thoroughly discussed by a team of three reviewers, publicly
 on [GitHub](https://github.com/scala/improvement-proposals) before the whole Committee votes on them during their
 monthly meetings. Second, there is a new stage where proposals are accepted as experimental features before the Committee
 votes again to promote them to stable features.
