Background Information on the 7.2 Upgrade

The invisible improvements

As part of the Treesoft Office 7.2 upgrade, we migrated the Qt framework from version Qt 4.8.6 to QT 5.15.2. Such a migration always involves a tremendous amount of work, as countless lines of source code have to be modified. Although the necessary changes are usually only marginal, with millions of lines of source code, the effort still takes several weeks. The implemented unit tests ensure the technical functionality of the individual modules. In order to maintain our high overall quality standards, we also carried out extensive and time-consuming practical tests.

In Treesoft CRM, we updated the TX Text Control we use from version 13 to version 29.

The text, email, fax, and letter editor has been completely redesigned using the updated TX Text Control. In the process, we have revised and reassigned all the names of the variables that you can use in the texts.

In addition, we have ported the entire mailing function from Delphi to QT, which is equivalent to a new development.
All drawing frames have been revised and we have introduced English variable names and variables for page numbering.
A total of 628,474 lines of source code have been edited for this upgrade – that’s equivalent to about 42 books of 500 pages each!

With all the changes documented here, we have nevertheless ensured that you can get started right away. The old variables are automatically converted when you open the texts, completely unnoticed by you, and the evaluation in Treesoft CAD also takes into account the old drawing frames with the German variables as before. If you reimport an old project, no changes are necessary.

Only if you want to use the new page numbering functions is it necessary to adjust the drawing frames. But even that is relatively easy, and if you don’t have time for it, no problem—just give us a call and for a flat fee of EUR 99.00, we’ll take care of everything.

With Treesoft CAD, you can still import and edit circuit diagrams that you created over thirty years ago with our software—and that’s unique in the market. We deliver upgrades that you can sit back and enjoy—just install them and get started. And that’s how it will stay, we promise.
