General notes

The release notes are divided into version sections.

Each section has a version number and contains the changes or adaptations that have been implemented in the CALC4XL software with this version.

Note:

You can determine the CALC4XL version you are currently using in the CALC4XL menu under the "License" item. 

The CALC4XL version number, example V 3.0.0.20 is composed as follows:

1st position: number of the major release 
2nd position: Minor version
3rd position: Patch version
4th position: Build number

Users who use CALC4XL versions with the same main version number can exchange their calculations with each other. A user with a lower main version number must update their CALC4XL version before opening calculations created with a higher main version number.

The use of a separate compatibility number is no longer necessary.
