PHP 8 has been officially released to the General Availability last November 26, 2020!

This new major update brings a whole bunch of optimizations and powerful features to the language and we are excited to drive you through the most interesting changes that will allow us to write better code and build more powerful applications.

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.
