  ## What We Shipped

  * Zap Protocol Fee Support

  ## Program: `meteora-dynamic-amm` `0.5.3`

  Program ID (mainnet and devnet): `Eo7WjKq67rjJQSZxS6z3YkapzY3eMj6Xy8X5EQVn5UaB`

  ### Changed

  * Upgrade to anchor 0.31.1
  * Add new endpoint `create_operator_account` and `close_operator_account` that allows admin to manage different operator accounts
  * Add new account `Operator`, that would stores `whitelisted_address` as well as their operational permissions
  * Add new endpoint `zap_protocol_fee` that allow operator to claim protocol fees and zap out to SOL/USDC or other token in pool and send to treasury address

  ### Breaking Changes

  * `withdraw_protocol_fees` can only be performed by an operator. The endpoint now requires `max_amount_a` and `max_amount_b` as arguments. The accounts passed in have also been changed.

  ### Fixed

  * Fixed initialization of stable swap error with `AmountNotPeg` due to the precision loss of the underlying vault exchange rate.
