Sunsetting Mercurial Support in Bitbucket
It's very sad to see bitbucket dropping mercurial support. Now only Facebook and volunteers are keeping mercurial alive. 
Sometimes technically better architecture and user interface lose to a non user friendly hard solutions due to inertia of mass adoption.So a lesson in Software development is similar to betamax and VHS, so marketing is still a winner over technically superior architecture and ease of use. GitHub successfully marketed git, so git and GitHub are synonymous for most developers. Now majority of open source projects are reliant on a single proprietary solution Github by Microsoft, for managing code and project. Can understand the difficulty of bitbucket, when Python language itself moved out of mercurial due to the same inertia.Hopefully gitlab can come out with mercurial support to migrate projects using it from bitbucket.For people who believe in self hosted solution can install Kallithea (https://kallithea-scm.org) or Rhodecode open source edition. Kallithea is used by Unity engine to manage their source code internally with mercurial.
