Environment Version

This protocol requires a different protocol environment version than Oxford. It requires protocol environment V11, compared to V10 for Oxford.

Smart Rollups

• The smart_rollup_originate operation now also takes an optional whitelist of public key hashes. This whitelist cannot be used yet (the sc_rollup.private_enable flag has to be set to true). (MR !9401)

• The transferring parameter from smart rollup client command get proof for message <index> of outbox at level <level> is now optional. (MR !9461)

• Enable the latest version of the WASM PVM (2.0.0-r3). Existing smart rollups will see their PVM automatically upgrade, and newly originated smart rollups will use this version directly (MR !9735)

Bug Fixes

• Fix reporting of gas in traced execution of Michelson scripts. (MR !6558)

Minor Changes

• Arithmetic errors on Michelson mutez type have been exported so they can now be caught outside of the protocol. (MR !9934)

Internal

• Register an error’s encoding: WASM_proof_verification_failed. It was previously not registered, making the error message a bit obscure. (MR !9603)

• Move some Michelson elaboration and erasure functions to the gas monad. (MR !10071)
