## [2.9.0] 2023-04-05 ### Added - Enabled XCC for mainnet release by [@birchmd]. ([#694]) - Added `set_owner` contract method which sets the owner of the contract by [@hskang9]. ([#690]) - New variant of submit function `submit_with_args` which accepts additional arguments along with the transaction such as the max gas price a user is ready to pay by [@aleksuss]. ([#696]) - Added the ability to create and fund XCC sub-accounts from external NEAR accounts by [@birchmd]. ([#735]) ### Changes - Replaced `rjson` with `serde_json` by [@aleksuss]. ([#677]) - Changed owner intended contract methods to now require owner or the contract itself by [@hskang9]. ([#676]) ### Fixes - Fixed nonce incorrectly being incremented on an out of fund failure by [@joshuajbouw]. ([#671]) - Fixed a check in promise results before executing cross contract calls (XCC) callbacks by [@birchmd]. ([#693]) - Fixed a reachable panic in `receive_erc20_tokens` by [@0x3bfc]. ([#709]) - Fixed a lack of minimum size checks when instantiating a new `EthGas` object by [@lempire123]. ([#722]) - Fixed a lack of division by 0 checks in `EthGas::Div()` by [@lempire123]. ([#718]) - Fixed the validation of the return of `exports:storage_remove` by [@0x3bfc]. ([#712]) - Fixed missing account validations of NEAR account IDs by [@0x3bfc]. ([#703]) - Fixed a reachable panic in the `exitToNear` and `exitToEthereum` precompiles if the input amount is greater than 1^128 when cast from a `U256` to `u128` by [@0x3bfc]. ([#681]) - Fixed a reachable panic in `modExp` due to arithmetic overflow by [@0x3bfc]. ([#688]) - Fixed the ability attaching values to Aurora specific precompiles, this no longer is possible, by [@0x3bfc]. ([#714]) - Fixed a return error if an ecrecover signature length is not exactly 65 by [@0x3bfc]. ([#717]) - Fixed size checks on input array passed to `exitToNear` and `exitToEthereum` precompiles by [@0x3bfc]. ([#684]) - Fixed missing gas costs in `exitToNear` and `exitToEthereum` precompiles by [@lempire123]. ([#687]) - Fixed a reachable panic due to out of memory in the `modExp` precompile by [@0x3bfc]. ([#689]) - Fixed an assurance that the `sender_id` has a balance greater than the amount in `ft_transfer_call` by [@0x3bfc]. ([#708]) - Fixed returning `0x` when a length cannot be cast as `usize` instead of returning an error in the `modExp` precompile by [@birchmd]. ([#737]) - Miscellaneous minor fixes by [@0x3bfc].
