Hey there... Just wondering if you have plans to upgrade this to the new v3 SDK? In the new SDK you're TypeTalkBot would become a TypeTalkConnector for the new UniversalBot class and it should be way simpler as all you have to do is the schema mapping work. The UniversalBot class does all of the session management now. If you're up for doing the work to port your lib to the new connector model I'm happy to answer any questions and code review your final bits.
