Apricot Phase 6

This is a mandatory security upgrade. Please upgrade your node as soon as possible.

The changes in the upgrade go into effect at 4 PM EDT on September 6th, 2022 on both Fuji and Mainnet. You should upgrade your node before the changes go into effect, otherwise they may experience loss of uptime.

You may see some extraneous ERROR logs ("BAD BLOCK") on your node after upgrading. These may continue until the Apricot Phase 6 activation (at 4 PM EDT on September 6th).
