Polygon PoS node out of consensus, Polygon Labs issuing emergency client upgrades

On 29 August, according to information from Polygon Labs, an emergency notification was issued that the Polygon PoS node in Austin and Kyoto, which was still running the old Bor or Heimdall, was out of consensus and needed to upgrade the client and follow up on the network. Austin is activated on the main network block 91,949,700, with the node running Bor v2.10.0 and above; Kyotto is activated on the block height 51,533,000, with the node running Heimdall v. 0.11.0 and above. Austin repaired two types of Bor resource depletion risk: L1-L2 Bridge Synchronization events that were not included in the Gas cap and could slow block processing; and TxDependency field lacked size limits, which could lead to the collapse of reciprocity。
