We do not have any references to the C SDK 2.0.5. However, you can always look into the Unity SDK 2.0.5 reference, since that version pretty much mirrored the C SDK method-by-method.
For even older versions, we do not have any available documentation. Naturally, we recommend that you upgrade, but if you have good reasons not to do that, reach out to us (Discord or email), and we will see what we can do.
