Breaking Changes
----------------

A DAL attestation operation now contains a new ``slot`` field, while the
``attestor`` field is removed. (MRs :gl:`!10183`, :gl:`!10294`, :gl:`!10317`)

RPC Changes
-----------

Operation receipts
------------------

- To better differentiate Deposits coming from 'rewards from bakers own stakes'
  from 'the edge bakers may take from their stakers rewards', the balance updates
  field has been specialized. The field {"staker":{"baker": <delegate_pkh>}} is now
  split into {"staker":{"baker_own_stake": <delegate_pkh>}} and {"staker":{"baker_edge":
  <delegate_pkh>}}. (MR :gl:`!12258`)

Internal
--------

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