With which version of Vtiger CRM is PDF Maker compatible ?

At the time our PDF Maker is compatible with Vtiger CRM versions:

5.4.0,

6.1.0, 6.2.0, 6.3.0, 6.4.0, 6.5.0,

7.0.0, 7.0.1, 7.1.0, 7.2.0.

We do not recommend running PDF Maker on Vtiger 6.0 as this version of Vtiger itself its very unstable.
