Schedule of Release

🗓️ MainNet Deployment

This release is scheduled to be deployed to MainNet on September 21, 2022, at 9AM PDT. We estimate the block height at that time to be 842,800.

We expect some amount of downtime during the upgrade, no greater than 2 hours.

At the conclusion of the deployment, MainNet will remain at Block Version 0.

Check out the block explorer to follow along with the upgrade!

What's New

🚨 Breaking Changes

  • Block Versioning allows for protocol evolution. Clients will need to keep up with these changes in order to read new blocks on the chain going forward.
  • mobilecoind will exit on startup when a ledger migration is necessary, unless the new --ledger-db-migrate command line argument is used, in which case it will migrate automatically. This flag does not do anything if the Ledger DB does not exist.
