SKM Power*Tools for Windows, Version 11.0.0.7 ________________________________________________________ IMPORTANT UPGRADE INSTALLATION NOTES: Please check your current version and revision prior to installing updates. You can determine the Version and Revision from the "Help menu > About PTW". The first two digits represent the Version and the last two digits represent the Revision. For example, Version 11.0.0.1 indicates Version 11.0 and Revision 0.1. All of the Revisions within the same Version are forward and backward compatible with other Revisions. When you are upgrading from one Version to another, the formats of the Project Database and the PTW Library are modified and aren't backward compatible. When you open a Project in a new Version, the project and library files are converted to the new format automatically; once this occurs, neither the Project nor the Libraries can be opened by an older Version of PTW. Therefore, we recommend that you make backup copies of your projects using the Project>Backup function prior to installing any new PTW Version. The project backup function will automatically copy your libraries, Datablock formats and query files used in the project. ________________________________________________________ WHAT'S NEW IN VERSION 11.0.0.7 (April 11, 2025): 1.
