Ethereum has encouraged vendors to switch to the Berlin-compatible version earlier.

The official Ethereum blog just announced the revised version in Berlin. According to the announcement, Berlin is ready, the first update, Ropsten, will be updated on March 10 and the mainnet will start on April 14. If you are running Ethereum nodes, you should upgrade your testnet to the Berlin-compatible version as soon as possible and to the mainnet to the Berlin-compatible version by April 7. The blog post also states that Ethereum node providers must upgrade their nodes before stiff competition from the networks they want to join. Due to the constant change of the blocking time, it is recommended to carry out the adjustment a few days before the due date.
