This mandatory release provides updates to support proof-of-coverage 11 (PoC 11) chain variables and performance enhancements.
Prior to this release we continued to provide updates for obsolete ledger features which were costing a significant amount of time.
Validators must update to 1.3.3 or higher before Oct 04 2021 to ensure they can support the PoC 11 chain variables.
It also reduces the snapshot size by up to 40%.
