ETHEREUM BERLIN MAINNET UPGRADE 4/15/2021

https://blog.ethereum.org/2021/03/08/ethereum-berlin-upgrade-announcement/ 

As an Ethereum user or Ether holder, is there anything I need to do?

If you use an exchange (such as Coinbase, Kraken, or Binance), a web wallet service (such as Metamask, MyCrypto, or MyEtherWallet), a mobile wallet service (such as Coinbase Wallet, Status.im, or Trust Wallet), or a hardware wallet (such as Ledger, Trezor, or KeepKey) you do not need to do anything unless you are informed to take additional steps by your exchange or wallet service.

********************************************************************************

What this means (Notice from Crypto.Com):

Crypto.‌com is supporting the upcoming Ethereum Berlin Upgrade, which will take place on 1‌5 Apr‌il 20‌21. To ensure the safety of users’ funds during and after the upgrade, we will suspend deposits and withdrawals of ETH and all ERC20 tokens (e.g. USDT, USDC, etc.) in the Crypto.‌com App, Exchange, and DeFi Wallet roughly 1 hour before the target block height 12244000.

So all ETH coins and ERC-20 tokens WILL BE LOCKED FROM MOVING DURING THIS TIME PERIOD.

********************************************************************************

Continued from the Ethereum.org post:

• Berlin is ready to be deployed!
• We’re moving fast: the first testnet to upgrade, Ropsten, is scheduled to upgrade on March 10th. Mainnet is scheduled for April 14th.
• If you are running an Ethereum node, you should upgrade it to a Berlin-compatible version ASAP for testnets and before April 7th for mainnet.
• See below for the list of Berlin-compatible client versions and details on the EIPs included in the upgrade.
• The Besu client has reported a bug in their previous Berlin release. Besu users should upgrade to version 21.1.2.

Berlin Timing

After months and months of planning, Berlin is finally here! The upgrade, which follows the Istanbul and Muir Glacier upgrades, is scheduled to go live on the Ethereum mainnet at block 12 244 000. We expect this to happen around Wednesday, April 14, 2021, but because of block time variability, the exact date may change.

Prior to being deployed on mainnet, the upgrade will go live on the Ropsten, Goerli, and Rinkeby testnets. The entire release schedule is as follows:

Ethereum node operators should upgrade their nodes prior to the fork block on the networks they want to participate in. Due to block time variability, it is recommended to update several days before the expected date. See the section below for the appropriate client versions to upgrade to.
