WSL Uses Ubuntu 14.04 with no plans to upgrade it soon. Some people have had success upgrading to 16.04, but I haven't run into enough recency issues to justify trying. It still has a lot of rough edges, but they seem to be actively working on it, so I'm hopeful this leads to a virtuous cycle of more developers using it and more investment from Microsoft.
