[d10r]

permit support was already added in https://github.com/superfluid-finance/protocol-monorepo/pull/1664, is available on newer testnets

[d10r]

piggy-backed fix for non-silent verification failure (https://github.com/superfluid-finance/protocol-monorepo/issues/1654)

[d10r]

Note regarding permit: the latest version 2.2 of FiatToken (USDC) added a variant of permit where the signature is just one parameter instead of 3. This has become common, but is non-standard (not as specified in https://eips.ethereum.org/EIPS/eip-2612).

• I don't see the permit support?

  • Missing update of the changelog.

permit was already there, see comments. no changelog update because only internal tooling changed.

no changelog update because only internal tooling changed.

It is a change to the deploy-test-network flow, so adding a line in changelog wouldn't hurt for future reference.
