Hello developer community, The Pagoda protocol team would like to announce a couple of minor RPC API changes. We plan to sunset the support of 2 experimental RPC methods: EXPERIMENTAL_check_tx and EXPERIMENTAL_broadcast_tx_sync. Both of these methods exist in the codebase, but were never included in our documentation due to their experimental nature. While we do not expect that they have real usage at this point, we want to be transparent about applying a breaking backwards compatibility change. The sunsetting will be active starting from nearcore version 1.37, which we estimate will be released in mid January 2024. In case you use any of these methods, there are other API methods you can use instead: * EXPERIMENTAL_check_tx can be replaced with tx method; * EXPERIMENTAL_broadcast_tx_sync can be replaced with broadcast_tx_commit or the new send_tx method (see info below). We plan to add an additional check to broadcast_tx_commit method. Right now, we check that the transaction and all the corresponding receipts were executed. Starting from 1.37, we will also check that all the blocks which include the transaction/receipts are the part of the canonical chain. This additional verification allows us to offer improved, stricter guarantees. However, the response time might increase by a small amount of time. Starting from 1.37, we will introduce a new method, send_tx, which allows you to guarantee the minimal level of execution, e.g., if you need to be sure that the transaction is included into the canonical chain, and you don't want to wait for the receipts, you can use send_tx with the INCLUDED_FINAL option.
