The Apache 2.4.x web server family continues to improve, albeit in incremental step forward. Apache 2.4 first debuted in February 2012, becoming the leading edge of Apache HTTTP server releases. With the Apache HTTP 2.4.17 update in October 2015, Apache added support for HTTP2.
Now with the new Apache HTTP 2.4.20 update, there are some incremental improvements, most notably in HTTP2 support.
