# Release of the final version of PVS\-Studio 4\.00 and end of public beta\-testing

Today, a month later we started public testing of the beta\-version of PVS\-Studio 4\.00, we announce a new final version released \(numbered 4\.00\.6\)\.

During the month of public testing, we released 5 intermediate versions, which allowed us to fix a lot of errors, implement many user preferences and improvements by the release of the final version\. \([What's new?](https://pvs-studio.com/en/docs/manual/0010/)\)\.

Let's once again point out the advantages of PVS\-Studio 4\.00 over PVS\-Studio 3\.64:

* A new set of general static analysis rules\. At present, it includes about sixty rules but their number will significantly rise in time\.
* Changes in the licensing policy\. Now there are three simple and clear license types with fixed prices: Single User License, Team License, Site License\.
* A new PVS\-Studio Output Window for diagnostic messages generated by the analyzer\.
* Performance increase both of the analyzer itself and its user interface\.

When announcing the release of the beta\-version, we said that we were planning to make the general analyzer free\. Due to various reasons, we failed to benefit from this approach during the time of public beta\-testing as we had planned\. That is why we will make the analyzer a completely commercial product and, of course, we will provide the trial\-version too\. To learn about the reasons why the free version has not proved to be a reasonable solution, see the post [here](https://pvs-studio.com/en/blog/posts/0089/)\.

Users of PVS\-Studio 3\.XX may use PVS\-Studio 4\.XX versions within the scope of the license they have purchased before\. However, these users will have only the trial\-mode of the general analysis unit\. To be able to use these diagnostic rules too, please write to us to learn about the terms\.
