radixdlt/babylon-node v1.1.3.1

Anemone (v1.1.3.1)

on GitHub

Summary

This is the v1.1.3 node, introducing a number of new features and improvements to the APIs.

This release is an optional update and fully Anemone-compatible. The key change is adding Engine State API (beta), which is a low-level, comprehensive API for reading state from the engine.

Details for node set-up are on the docs site here. There should be no need for configuration changes as part of updating to this release. For those running natively, you should update both jar and native library from the attached assets. For those running in Docker, the new image is available on dockerhub.

Please note also:

• It is impossible to go back to v1.1.2 once you've updated to v1.1.3.
• When v1.1.3 starts for the first time, it needs to generate indexes for the database, which may introduce downtime. As a result, this may cause your validator node to miss proposals. You may wish to swap to a back-up node, or unregister for this hour or two, to mitigate this.
