Many criticized the developers ' decision to implement the update during the holidays. According to Ethernodes, support for Muir Glacier has not yet been announced by Coinbase, Bitfinex, Polonius and some other exchanges. At the time of writing, 14.5% of the nodes have not updated the SOFTWARE to the latest version.
The Ethereum community did not expect that the "complexity bomb" would begin to affect the time of block generation so quickly, but the calculations were wrong. In order not to delay the hard fork Istanbul to include the relevant changes, the developers have proposed a separate upgrade.
The "complexity bomb" on the long road to Ethereum 2.0 is being postponed for the third time.
Recall that on December 31, the developers of the Parity client discovered a bug that prevents the correct synchronization of full nodes with the Ethereum network.
