This release contains several security hotfixes, and consensus improvements:
The security hotfixes were introduced for the Move VM and block execution:
(i) Add layout validation and improve cache flushes
(ii) Fix constant size computation to match DAG-based layout construction
(iii) Fix closure load and enhance string checks
The consensus improvements were to address race conditions, and transient serialization issues.
Impact on nodes:
Validators: Upgrade required.
Fullnodes: Upgrade required.
Deposits and Withdrawals: No impact.
