We have couple of this kind of bug reports: https://bitbucket.org/tortoisehg/thg/issues?q=This+version+of+TortoiseHg+requires+Mercurial+version https://bitbucket.org/tortoisehg/thg/issue/1393/ubuntu-package-from-ppa-has-wrong https://bitbucket.org/tortoisehg/thg/issue/1876/better-api-mismatch-warning-dialog
Because TortoiseHg depends on internal apis of Mercurial, we cannot guarantee the compatibility with the unreleased Mercurial version. Is it possible to lower the required Mercurial version?
