HTTP/2

HTTP was created by Sir Tim Berners-Lee, the founder of the World Wide Web, back in 1989. The first version, HTTP 1.0, was introduced in 1996, followed by HTTP 1.1, which was introduced in 1997. HTTP 1.1 is still the most common version of HTTP out there.

In May 2015, HTTP/2 was released, which provided several improvements and enhancements to the old HTTP 1.1 protocol, such as server-to-client push messages and binary data support, to name just a couple. Ever since, it has been adopted by many websites and is slowly becoming the standard version of choice for websites.
