Overview
This release version includes a coordinated protocol update that shuts down Olympia mainnet (which is estimated to be enacted on or about 2023-09-27, at which time mainnet will migrate from Olympia to Babylon).
The protocol update requires 79% of an active validator set to signal their readiness and can be enacted between epochs 32718 and 32723. Refer to https://docs.radixdlt.com/main/node-and-gateway/coordinated-protocol-updates.html for more information on coordinated protocol updates.
This release also includes changes to the /olympia-end-state Core API endpoint: it is no longer a part of the Core API. Instead, it runs on its own http server, which allows to expose it on an external address, while keeping the Core API internal.
It can be configured using the following parameters: api.end-state.bind.address/api.end-state.port (default 0.0.0.0:3400).
Core API now defaults to 127.0.0.1:3333 (which can be changed using api.bind.address/api.port).
If you haven't already, you will need to run a Babylon node after the switchover. If you wish to have your nodes automatically update, please see the introduction to the Olympia Babylon migration.
