MainNet and TestNet Update: Go-Algorand 3.19.0

MainNet and TestNet have been updated to 3.19.0 today, Wed Oct 25, 2023 10:30AM EDT (14:30 UTC). This release does not contain a consensus upgrade.


In this release we add support for hot and cold data directories for algod, enhance the simulate endpoint by returning app initial states, and speed up starting up private networks by allowing pre-generation of keys. Backend support for future features are also included - stay tuned!

What's New

  • Hot/Cold data directories: Support for specifying different destinations for data instead of just a single data directory
  • Pre-generated private network keys: Speed launching new private networks for development by re-using pre-generated keys
  • Simulate: Return application initial states accessed during simulation
  • Config: Add MaxBlockHistoryLookback option
