# We released a new version of PVS\-Studio code analyzer \- PVS\-Studio 3\.52

We released a new version of PVS\-Studio code analyzer \- PVS\-Studio 3\.52\.

* New online help has been added\. The previous help system integrated into MSDN\. It was not very convenient for some reasons \(both for us and users\)\. Now PVS\-Studio will open the help system on our site\. We refused to integrate it into MSDN anymore\. As before, the pdf\-version of the documentation is also available\.
* We stopped supporting Windows 2000\.
* The settings page "Exclude From Analysis" was deleted, there is now the page "Don't Check Files" instead\.
* Work in Visual Studio 2010 was improved\.
* We eliminated the issue of integration into VS2010 whenreinstalling\.
* We fixed work of the function "Mark As False Alarm" with read\-only files\.
