  • Account data was rearranged to put fields that are often used with gPA first

  • The CreateGroup instruction now requires an insurance_mint account, which is used as the mint for the insurance_vault token account it creates. Pass the USDC mint address.

  • The token with token_index zero is now required to be the insurance_mint. Trying to register a different token for index zero will now fail.

  • New instruction: LiqTokenBankruptcy to resolve insurance fund payouts and socialized loss for bankrupt accounts.

  • The PerpCreateMarket instruction no longer requires a quote_token_index argument. The USDC/insurance mint is always used as quote currency for perps.

  • The UpdateIndex instruction now requires the oracle account to be passed for logging purposes.

  • New instructions: AccountEdit, TokenEdit, PerpEditMarket for reconfiguring.

  • The delegate field on MangoAccount is now used and many instructions can be called by the account delegate.

  • TokenUpdateIndexAndRate now maintains dynamic optimal and max rates for token interest rates.

  • Renamed instructions:

    • create/close_group -> group_create/close
    • create/edit/close_account -> account_create/edit/close
    • update_index -> token_update_index
    • create/set_stub_oracle -> stub_oracle_create/set
