Hi Rohit, thanks for this, but in this case, we just want to remove the symbols from the export list. These functions used to exist, but were moved into prepare!. This is a bit confusing no doubt, sorry.

@aviks I wasn't aware of the functions being removed as they are still in the docs. If they do not exist now.. Should the docs be updated to reflect that and mention the usage of prepare! instead of these functions?

[aviks]

Yes, the docs should be updated to mention prepare!. It's a big problem that it hasn't yet been.

@aviks Can this be merged now?
