After much consideration, we've decided to remove Mercurial support from Bitbucket Cloud and the API. Mercurial features and repositories will be officially removed from Bitbucket and its API on June 1, 2020. What used to be a very fragmented version control software market has rapidly matured. Mercurial usage on Bitbucket is steadily declining, and the percentage of new Bitbucket users choosing Mercurial has fallen to less than 1%. At the same time, Git has become the standard. According to a Stack Overflow Developer Survey, almost 90% of developers use Git, while Mercurial is the least popular version control system with only about 3% developer adoption. Given that Git has emerged as the version control system of choice for the industry, we have decided to focus our priorities and roadmap on building the best possible experience for the market and our users. Read on to learn more about what led to this decision, timeline, and migration resource support.
