Overview

Go-Algorand 3.18.0 is a minor release introducing the ability for unnamed resources to be referenced from simulated transaction groups. The release also contains minor enhancements and bug fixes.

What's New

• 🔮 Simulate: Transactions can now be evaluated by simulate without specifying foreign references (without populating apps/accounts/assets/box arrays). (#5366)
• 🧱 Blocks Endpoint: Introducing Algod's /v2/blocks/{round}/txids endpoint. With this, you can now retrieve top level Transaction ID's in a given block. (#5611)
• 🪪 API Authentication: Use the DisableAPIAuth configuration option to make Algod's public API endpoints accessible without providing an Authentication token. (#5625)

Compatibility Note

Raspberry Pi ARM32 support is not available in this release due to compile issues.
