Summary

Upgrade the Registry Canister to Commit 3e64518

__Proposer__: daniel.wong at dfinity.org

__Source code__: [3e645182ac06c7b761040615db4e3d44a8349351][new-commit]

[new-commit]: https://github.com/dfinity/ic/tree/3e645182ac06c7b761040615db4e3d44a8349351

Features & Fixes

Added

  • Enforce that every hostos_version_id matches its HostosVersionRecord's registry key.

Changed

  • The engine controller canister may now set the state limits in UpdateSubnet's resource_limits

(maximum_state_size, maximum_state_delta) on CloudEngine subnets. A limit it leaves unset keeps its current value instead of being reset, and the query limits remain governance-only.

  • UpdateSubnet can now enable SEV on an existing subnet, not only at subnet creation. Disabling SEV

is still rejected, and enabling it only succeeds if the subnet's nodes all have a chip ID and its GuestOS version has launch measurements, as the SEV invariants demand.

  • replica_version_id on ReplicaVersionRecord is no longer optional in code.

Setting this field has been mandatory for some time, and any previous records with unset values have been backfilled.
