Stellar activates Protocol 28 'Adapter' upgrade on mainnet
- —Protocol 28 went live on Stellar mainnet on Sept. 16, 2026 at 17:00 UTC
- —CAP-86 introduces sparse host functions for staged contract data migration
- —CAP-85 lets developers upgrade a group of contracts via a shared executable reference
- —CAP-83 allows validators to vote before receiving the full transaction set
Why it matters: The upgrade eases data migration and bulk contract upgrades on Stellar, but developers must manually verify data compatibility.
