Given a copy of WordPress installation, how do I find out what version it is from the source code?


You can find the version in wp-includes/version.php, the $wp_version variable.

It can also be found in the readme.html file in the root of the WordPress folder.

    If you happen to be looking at a development version of WordPress, the number in readme.html may not be accurate. For example, in the WordPress 3.6 development versions, readme.html continued to show "3.5" until Release Candidate 1. – Ben Miller - Reinstate Monica Aug 2 '13 at 17:05

    Seems like the version is no longer included in readme.html. I am using wordpress 5.2. – Alex Jun 2 '19 at 3:40

open your site and in meta tag with name="generator" for example

<meta name="generator" content="WordPress 3.5.2" />

    though a valid way of finding the version, this is not from the source code, rather its from the output of running the source code. – icc97 Aug 2 '13 at 12:39
