The Stellar public network successfully upgraded to Protocol 13, introducing new features like fee-bump transactions and fine-grained asset authorization. Developers must update their software to avoid compatibility errors.
The Stellar network completed its upgrade to Protocol 13 following a coordinated vote by validating nodes. The upgrade introduces two immediately usable features: fee-bump transactions, which simplify fee handling, and fine-grained asset authorization for better access control. Developers using outdated Stellar SDKs, Horizon, or Stellar Core may experience XDR errors, ledger ingestion failures, or catchup loops. The Stellar Development Foundation provided comprehensive documentation and guides to help the ecosystem prepare, including detailed specs (CAP-15 and CAP-18) and tutorials for implementing the new features.
