Errors upgrading from metaplex 0.15.0 to 0.18.0

The following code works perfectly on metaplex 0.15.0:

let createOutput = await metaplexNFTs.create({
  uri: uploadResponse.uri, 
  name: "Token name",
  sellerFeeBasisPoints: 0, 
});

(original code also has .run() which I understand is no longer necessary and have removed)

However I'd like to move to a newer and better supported metaplex release.

I have downloaded the latest metaplex JS 0.18.0 and ran it on my local validator - can I confirm I need to do this? I imagine the on-chain app needs to be upgraded when the JS package does.

solana program dump -u m "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s" metaplex_token_metadata_program.so
solana-test-validator --bpf-program "metaqbxxUerdq28cj1RbAWkYQm3ybzjb6a8bt518x1s" on-chain-programs/metaplex_token_metadata_program.so

In Metaplex JS 0.18.0 the code gives the following output:

  $ npx jest -t 'identity token for Alice'

By the way, it's quite possible I've missed something else I need to do after a Metaplex upgrade - I can see https://github.com/metaplex-foundation/js/releases and the README but things like upgrading the metaplex program above I'm just guessing at. Happy to send PRs if the docs just need to be written.
