Protocol upgrades

Stellar protocol upgrades are network-wide changes to consensus and core functionality. Validators must update their software to stay in sync. Upgrades may add new features, improve transaction performance, or strengthen network security.

The Latest

Protocol 23

CAP-0062

Allows the network to evict persistent entries from the live state BucketList to a separate BucketList containing archival state

CAP-0063

Defines a new structure for transaction sets that allows for applying Smart Contract transactions with multiple threads while maintaining bounded application time

CAP-0065

Maintain a fully-populated cache of all live WASM modules -- parsed, validated and translated -- at all times, across all ledgers, eliminating parsing and validation costs from the WASM VM instantiation process

CAP-0066

New resource type for Soroban reads, distinguishing between in-memory and disk reads and automatic restoration for archived entries via InvokeHostFunction0p

CAP-0067

Emit transfer, mint, burnt, clawback, fee, and set_authorized events in Classic in the same format as Soroban so that the movement of assets and trustline updates can be tracked using a single stream of data

CAP-0068

Soroban host function for getting the executable corresponding to an Address

CAP-0069

Soroban host functions for conversion between String and Bytes types

CAP-0070

Ledger configuration settings allowing the Stellar network to dynamically adjust ledger close times, nomination timeouts, and ballot timeouts to facilitate controlled, incremental improvements to block time performance
