New default Solidity version and new default EVM version

Is it my fault or your fault? No, its just the default! OK stop groaning…and notice that Remix is up to date with the coming network upgrade.

The default compiler is Cancun and the default Solidity version is 0.8.24.

Uniswap v4 Template

We have had the Uniswap v4 template in Remix — but it was previously called Uniswap v4 Periphery. So now we have renamed it to something that you can identify more easily.

To load this template in the File Explorer, click the hamburger menu and then select Create. You’ll see it in the Uniswap V4 section.
