Latest Horizon and RPC changes

[Shaptic]

Horizon Changes

Horizon v2.31.0 made the following changes:

• New endpoint: POST /transactions_async allows asynchronous transaction submission (code: stellar/go#5188).
• Error schema change: POST /transactions now includes a the hash in its timeout response, which may or may not require code changes depending on how your SDK handles transaction submission errors (code: stellar/go#5328).

Soroban RPC Changes

RPC v21.4.0 added the following endpoints:

• getTransactions, which returns pages of transaction details (code: stellar/soroban-rpc#174).
• getFeeStats, which returns aggregated fee statistics over a few ledgers (code: stellar/soroban-rpc#172).
• getVersionInfo, which returns detailed information about the software versions the RPC server is running (code: stellar/soroban-rpc#132). Please keep in mind that this endpoint accidentally used snake_case for response fields and it will be updated to camelCase (see soroban-rpc#164) as part of Protocol 22's breaking changes when the time comes.
