While I do not see any changes in default VS tabs behavior, VS 2015 stopped support for add-ins and that required substantial internal changes in Tabs Studio. Now, instead of VS Add-in Manager, Tabs Studio is presented in VS Extensions and Updates dialog. You can disable and uninstall it from there (though to uninstall all files it is still recommended to use Control Panel):
