Highlights

  • Stateful Smart Contracts: Algorand Smart Contracts (ASC1) offer the foundational attributes of security, scale, and decentralization found in Algorand’s Layer-1 protocol, allowing developers to take advantage of the network’s speed, cost-effectiveness, and simplicity. Enabling complex governed transactions with simplified tools that can build a wide range of applications, and removing the technical barriers that undermine blockchain adoption. Algorand’s Smart Contracts are highly flexible, reliable in that they are executed on a tamper-proof (trustless) network providing the transparency needed, with error-free, immutable, and accurate applications.
  • Rekeying Support: Algorand's Rekeying offers a seamless, easier experience for users and custody providers by allowing flexible changes of Private Spending Keys anytime without changing Public Addresses, giving Public address more continuity, and reducing operational overhead with the changes of Private Spending Keys.
  • Fast Catchup: Fast Catchup is a new feature and will rapidly update a node using catchpoint snapshots. A new command on goal node is now available for catchup. The entire process should sync a node in minutes rather than hours or days.
  • Performance Improvements and Bug Fixes: Note that there is a one time long startup time to re-encode the accounts database, which will take an additional few minutes to complete.

Protocol Upgrade

This release contains a consensus protocol upgrade, which implements the following spec:
https://github.com/algorandfoundation/specs/tree/3a83c4c743f8b17adfd73944b4319c25722a6782

Other Notes

A database migration is included this release, which will add a one-time startup delay of a few minutes. This is for re-encoding of the accounts database, if needed. Note: the database schema will remain compatible with the previous release. Please plan your upgrade accordingly.
