Ethereum Delayed Glamsterdam Upgrade
Ethereum developers have postponed the Monday Glamsterdam upgrade on the Hoodi test network after security researchers identified a risk to existing smart contracts. The upgrade, originally scheduled for Oct. 26 at 17:42:48 UTC, was delayed due to concerns over how a proposed change to Ethereum's gas accounting interacts with contracts already running on the main network. No replacement date has been announced.
