Upcoming Bor & Heimdall Mumbai Upgrade: v0.3.0 [No Action Required]

We are working on Bor & Heimdall upgrades that we plan to release next week on the Mumbai Testnet. We have added a new CLI in Bor and have also changed the way Bor and Heimdall are deployed to follow DevOps best practices and make it easier to manage the processes.

This upgrade is important as it is backwards incompatible. We will give validators enough time to upgrade to the new version before discontinuing critical support for v0.2.x

In our next announcement, we will also include a detailed changelog and upgrade instructions.
