In the C# API, methods have been renamed, changed to properties, or made to
return interfaces instead of classes. Some parameters have different defaults.
Very little of the implementation has changed.
Lua API hasn't changed at all, but Comm/Input/SaveState libs are now in
Client.Common (and Comm now delegates to IComm).
Changed param clear of IGui.DrawNew from bool? to bool (default value remains
true), made IGui and GuiLuaLibrary inherit IDisposable, added
GetDefaultTextBackground to IGui, applied fix from 6b3071d8a to
GuiApi.DrawString, replaced background box drawn by Lua API
gui.drawString/gui.drawText with what I think is a shadow (now matches
GuiApi.DrawString)
