MainNet and TestNet have been updated to 3.15.0 today, Wed Mar 22, 2023 10:30AM EDT (14:30 UTC). This release does not contain a consensus upgrade.

Overview

This release includes the new simulate endpoint for evaluating transactions, networking optimizations, and lays the groundwork for better configuration management and conduit support.

:warning: Minor breaking change for goal users: The goal node catchup functionality when run with no arguments has changed. You will now be prompted to confirm the action if a catchpoint label is not fed as an argument to the catchup command. Please revisit any automation around fast-catchup a node and ensure they are properly adapted.

What's New

  • Connection deduplication: improved networking code
    • Relay Runners – enable this feature by setting the node PublicAddress config.json value to its public endpoint address (eq. to SRV address including port number) to optimize its bandwidth usage
  • Simulate endpoint: local evaluation of transactions
    • Ever wondered what effects your transaction could have on the blockchain state? This feature is for you! Now you can evaluate your transactions before sending them out to the network. See here for more information.
  • Profiles for algocfg: a set of profiles for configuration defaults
    • Node configurations can be tricky! Use this feature to get started on properly configuring your node.
  • Algod follower mode: a new operation mode for use with upcoming conduit release
  • New private network default template and automatic start
    • Executing goal network create --rootdir "ANY_DIRECTORY" --start will create and start a private network using the default private network template. This is great for testing your dApps on a private network before deploying them on a public network.

Refer to our developer release article here for more information on these features!
