Yes it does, however, checking what version of MODX your site is running on is simple and important. Something to keep in mind - don't get "version" confused with "Evolution" versus "Revolution". Those are actually two different platforms and completely separate code bases. For example, Evolution may be at version 1.0.6 and Revolution at 2.2.1. We hope this clears up any confusion between MODX versions, and Evolution versus Revolution.
The first step in finding your MODX version is to login into the MODX Content Manager typically found at www.yourdomain.com/manager. Are logged in now? Good. Let's keep rolling.
You can find your current version of Revolution in the upper-left corner of the screen.

In Evolution, it's in the upper-right corner of the Manager. If you are used to editing pages from a front-end manager (editing while you can see your web pages), you are likely using Evolution and will need to click on the "Manager" button along the top in order to access the manager area.

Updates like these happen all the time across the open source community, but most updates are platform enhancements and aren't necessarily vital. Because Evolution is an older code base that is primarly being maintained rather than expanded on, updates will occur less often but are likely to be quite important, such as the most recent upgrade to 1.0.6 that cleared up some vulnerability issues. Revolution changes are occurring more often as MODX expands on it's newest code base.
Whenever large changes occur in versions, particularly when vulnerabilities are found, we like to notify our clients and let them know upgrading is a good idea. Clients under maintenance agreements with us will automatically get scheduled for testing and the upgrade. Others are welcome to contact our support team to perform the upgrade.
