go-algorand 5.0.0-stable Release PR

[Algo-devops-service]

Overview

This consensus upgrade release brings post-quantum (Falcon-1024) account signatures, support for larger "big" transactions with per-byte fee pricing, support for larger app sizes, and AVM v13. It also removes the long-deprecated dryrun REST endpoint and tealdbg tool in favor of simulate.

What's New

• Post-quantum accounts: native Falcon-1024 account signatures, PQ delegated LogicSigs, and new algokey pq commands for PQ key management
• Big transactions: larger transactions (notes up to 4KB, up to 7 extra program pages, larger LogicSigs) priced via a per-byte fee surcharge, with simulate reporting fee usage
• AVM v13: poseidon2 hash function, app_params_set, new box params and "foreign" box opcodes, variable-length branches, and automatic salting of v13 programs to avoid on-curve LogicSig hashes
• New node API: GET /v2/node/peers endpoint and goal node peers command
• Removed: dryrun and tealdbg (use simulate instead)

Protocol Upgrade

This release contains a protocol upgrade.

Indexer and conduit runners will need to update their installations to support the new consensus upgrade. You can find binaries here:
