MainNet and TestNet have been updated to 2.7.1 today, Wed May 26, 2021 10:30 AM EDT (14:30 UTC)

Protocol Upgrade

This release will require a protocol upgrade.

This release contains a consensus protocol upgrade, which implements the following spec:

Spec PR: #2286

Highlights

This release represents a major milestone in smart contract functionality, as well as serves as a vote for the future of governance on chain.

In this release:

• Governance vote - see Blog
• Algorand Virtual Machine (AVM) v0.9
  • Control Flow
    • New OpCodes: callsub, retsub
    • Allow backward jumps or indirect jumps
    • Dynamic cost accounting
  • Opcodes: Math related
    • New OpCodes: shl, shr, divmodw, exp, expw, sqrt, log2
    • Byteslice arithmetic
  • Contract-to-contract composability - allow contracts to share scratch space in a transaction group
  • Createable IDs in gtxns (they are not really deterministic, but rather new app/asset idx are available for subsequent apps within a transaction group)
  • Increased Program Limits
    • Ability to pay for extra pages
    • Pool fees - as long as fees in a covered in a gtxn, allow 0 fee txns
    • Increase ASA URL size from 32 bytes to 96 bytes (better IPFS support for NFTs)
    • Combine clear and approval limits
    • Combine schema key/value sizes
  • Optimize int/byte constant in assembly
• Participation key registration improvements (e.g. check valid ranges)
• Miscellaneous optimizations and test improvements

Changes

1. AVM

• New Features
  • Control flow (callsub, retsub; backward/indirect jumps; dynamic cost accounting)
  • New math opcodes (shl, shr, divmodw, exp, expw, sqrt, log2) and byteslice-oriented math
  • Add ability to pay for more program space
  • Allow future app call transactions to read the scratch space of previous transactions in the same transaction group for contract to contract composability
  • Combine Clear and Approval Program size limits
  • Combine app state key/value size limits
  • Expose creatable IDs to AVM code within the same group
  • Pool fees in a transaction group and allow one user to pay all fees
• Enhancements
  • Allow AVM code to access a max number of foreign refs
  • Increase ASA URL size from 32 bytes to 96 bytes to support NFTs with longer IPFS URLs
  • Optimize constant assembly
  • Regularize access to "foreign" references
• Bug Fix - check setbyte length properly

2. REST API

• New Feature - add the AppsTotalExtraPages account field to the response returned by the /v2/accounts/{addr} endpoint
• Enhancement - make account endpoint produce deterministic JSON
• Bug Fix - make extra-program-pages and apps-total-extra-pages optional in order to do not exposing them before the protocol switch
