Nice! Is there a sample output of the subwasm results? Could we maybe generate a draft release off this branch to trigger the workflow to see the results?

[peterwht]

@evilrobot-01 Absolutely! Here is some test output on fork:

• https://github.com/peterwht/extended-parachain-template/releases/tag/test-v8
• https://github.com/peterwht/extended-parachain-template/actions/runs/6305423211/job/17118818501

Excellent! I see the subwasm info artifacts are attached to the action run and not the release. Just checking whether this is intentional?

[peterwht]

@evilrobot-01 Good catch! I will add those in as well
