The PHP team released PHP 7.4 today, bringing a few bigger new features and many small refinements.
PHP preloading can yield a significant performance boost, especially for large frameworks using a lot of libraries.
PHP extensions can be loaded directly from userland, meaning this can be done without configuration on the server.
Arrow functions, like in JavaScript, allow for shorter syntax when you define closure functions. Class properties can be type hinted. You can use the spread operator (...) in arrays.
