You'll also need to commit the Cargo.lock changes, and be sure to maintain borsh's dependency on hashbrown to 0.12.3, otherwise on-chain programs can't build.

Otherwise, this is good to go!

Ah darn, we'll have to update the script to work with the new crate names. I put in #4698 to fix that up

Suggested change

	solana-rpc-client = "1.16.1"
	solana-rpc-client = "1.16.2"

I think this change is relevant -- #4703
I'm not sure if sticking with particular version of hashbrown is better than adding getrandom or not. If this getrandom custom doesn't break anything, than I would argue that sooner or later we will have to upgrage hashbrown and, hence, getrandom. Maybe there is something else I'm not aware of
