I don't know if it's the best place to talk about that, but since it seems that Ogre 1.x developement happen mostly on GitHub, and only the 2.x branch is actively worked on BitBucket, it seemed more relevent.

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.
By June 2020 they will definitively remove all Mercurial repositories from the platform. We probably need to find a new home for Ogre development. I know some of the maintainers (notably Matias) seems to really prefer hg over git. (And we are not the only OSS project that perfer it over Git, an excelent example is the SDL library.)
I am curious to know what are your thoughts about this? This is mostly a matter and a decision that concern the main maintainers of Ogre, but I think it affects everybody anyway, notably the contribution and pull request workflow...
