Scheduled - Flow mainnet will undergo another height-coordinated upgrade.

The upgrade will NOT cause any network downtime except for transaction execution being paused for a few minutes while the execution nodes restart.

Resolved - The issue has been resolved and transaction execution has resumed.
However, one of the execution nodes run by the Foundation has been stopped as we are still investigating the root cause.

Update - Reminder - Mainnet HCU tomorrow.
Jun 13, 00:37 UTC
Update - The mainnet HCU has been postponed to Thursday, 13th June 8:00 AM Pacific (3:00 PM UTC) (instead of Tuesday).
Jun 8, 16:48 UTC
Scheduled - Flow mainnet will undergo a height co-ordinated upgrade (HCU) on Tuesday, June 11, 2024 at 8:00 AM Pacific (3:00 PM UTC)

The upgrade will NOT cause any network downtime except for transaction execution being paused on mainnet for a few minutes while the execution nodes restart.

The upgrade will introduce the following two changes to the Flow Virtual Machine:

1. Add support for the 'dependencyCheck' in preparation for the Cadence 1.0 launch
The 'dependencyCheck` allows the chain to track contracts which have not yet been staged for Cadence 1.0 upgrade. For more information see this pull request - https://github.com/onflow/flow-go/pull/5908/files.
The service account contract will also be updated that day right before or after the HCU (see forum post - https://forum.flow.com/t/upgrade-coming-to-flow-service-account-smart-contract-to-track-non-updated-cadence-1-0-user-contracts/6131).

2. Skip throwing an error from GetBlock function in Candence. For more information see this pull request- https://github.com/onflow/flow-go/pull/6022.

Thank you
