574 open issues exist for TypeScript on Codeplex. https://typescript.codeplex.com/workitem/list/basic
"Please note: since we’re moving to a new issue tracker and a new codebase, we are not copying all issues over. If you have issues in the current CodePlex issue tracker, please try them against the new codebase and file them in the GitHub issue tracker if they still repro."
Github is back up to 117.
Managing an open source community is something that the TypeScript leadership still have yet to learn. They weren't concerned about coordinating with TC39 on module syntax (they shipped 1.0 with an arbitrary snapshot), they were never very interested in accepting code, and they don't value the time users take to document bugs and edge cases.
tl;dr the move to Github is lipstick on a pig. It is a distraction from the real changes they must make on order to collaborate well with others.
