Radar Relay has moved to the 0x Protocol version 2.
This migration allows for new features to be added to Radar and will require action on the part of users.
The version of Radar Relay built on 0x v1 will be available at the same time to allow users to cancel old orders.
Disabling token allowances and cancelling orders on v1 will have no impact on v2.
Actions for users
1. Go to Radar Relay v1 and cancel all old orders
2. Go to Radar Relay v2 and re-enable token allowances
This move to the new version of Radar Relay connects to new API endpoints and involves some changes to the format of data requests for the API. These changes will not affect users going through the web interface.
