Hi there, I am wondering where I can access the old Hail 0.1 docs? I need to be able to update some data using the old system. However when trying to access them through Hail’s website i get a 404 error. Many thanks

They’re not currently published anywhere. I’ll fix that today.

Just keep in mind that we don’t support 0.1 anymore, so we can’t really answer questions about it and it may have bugs. Updating to 0.2 would give you much better performance as well.
