December 23, 2019 Ethereum’s announced upgrade schedule prompts developer criticism.

The “Muir Glacier” upgrade, which delays a planned increase of mining difficulty, has been scheduled for New Year’s Day, a common work holiday, by the Ethereum Foundation. Among those critical of the timing is Jorge Izquierdo, CEO of Aragon One, who, after tweeting “Now someone from my team has to work on a day that they were free,”, announced that Aragon will not be implementing the upgrade until January 2nd.
