The PHP development team announces the immediate availability of PHP 8.0.0. This release marks the latest major release of the PHP language.

PHP 8.0 comes with numerous improvements and new features such as:

    Union Types

Just-In-Time compilation
PHP 8 introduces two JIT compilation engines. Tracing JIT, the most promising of the two, shows about 3 times better performance on synthetic benchmarks and 1.5–2 times improvement on some specific long-running applications. Typical application performance is on par with PHP 7.4.
