What version of Drupal is your site using?
June 22, 2010 | 
Katy A new project I'm working is upgrading www.Fightwriter.com. It has 2500 articles about boxing. The original site was created in Drupal 4.5 and will be upgraded to Drupal 6.
See my blog post at http://www.seascapewebdesign.com/blog/keep-your-website-healthy-and-secu...
At first I didn't know how to determine what version of Drupal the current site is in. It does not have a CHANGELOG.txt file. Or a Drupal version constant like Drupal 5 and 6 has.
However, the current version of Drupal 6 does have a list of the major changes that went into each new release beginning with 4.x. I consulted this file called CHANGELOG.txt and using a process of elimination, I discovered that the current site is built with Drupal 4.5. Here are some tips for you:

Download the most recent version of Drupal and read the CHANGELOG.txt. It lists the the major changes that happened with each of the major releases of Drupal.
1. First thing to do is to read the CHANGELOG.txt file. It’s located in the root directory of your Drupal website. All versions of Drupal from 4.5-present have this file. Check the top entry in this file. It will have the Drupal version number. Unfortunately for our purposes today, many developers delete this file on live sites because it is perceived as a security risk.
2. Second thing to do is to check the VERSION constant in modules/system.module. This was added in Drupal 5.0.
3. If you can’t find the VERSION constant in modules/system.module then your version number is most likely 4.7 or earlier. In Drupal 4.7, the site 'offline for maintenance' feature was added.
4. In Drupal 4.6, a site-wide contact form (modules/contact.module) and search block were added.
5. In Drupal 4.5, all GIF’s in the default themes were replaced with PNG’s. If you can’t find the modules/contact.module, then your site is most likely Drupal 4.5.
6. You can actually download the 4.x versions on Drupal.org. Then you can compare the files in more detail. This article covers the major releasees and not the minor releases. For example upgrading from 4.51-4.52, is called a minor release.

Use PHP code to display your Drupal Version number
Here is how you can display your Drupal Version number without having to check the Available Updates page. I often turn this off because I find the warning messages to update very annoying.
- Add a block. Title it "Drupal Version".
- Choose PHP Input format.
- Use plain text editor to add this code:
<?php
print VERSION;
?>
- Click Save
- Configure your block so that only you, the Admin, sees it.
Let me know how it works for you.
