How to get more information about the models available for gpt4all?

[DamirTenishev]

I can see the list of models, but I can't find:

1. When the model was created and when it was updated last time. I just want to know how old the data it trained on to compare models in terms of applicability to my questions related to some nowadays things.
2. I haven't seen any "Update" button for a particular model at all. Does it mean that models never get updated?
