ChainCatcher message, the Sui mainnet has been upgraded to version V1.22.0, and the Sui protocol has been upgraded to version 42.

It is reported that the key points of this upgrade include: providing more accurate rounding calculations in the Deepbook accessor function (read-only), adding support for the serialize-signed-transaction and serialize-unsigned-transaction flags, fixing a bug where the sui client verify-bytecode-meter incorrectly returned the tick used by the last function to be verified as the tick used by the last verified module, and enabling EC (Elliptic Curve) operations in Move, etc.
