New WinOLS Version 4.69 / 5.14 published.



New: WinOLS® is now a "Registered Trademark".



Another important step has been taken: The common code base of WinOLS4 and WinOLS5 has now been separated so that both can go different ways in the future. For this reason, updates will no longer be published at the same time in the future.

In WinOLS4, no more new features will be added, only errors that occur will be corrected. As a result, the stability will of course get better and better.

WinOLS5, on the other hand, is being developed dynamically as always and adapted to the changing engine control units.

Checksum DLLs are being further developed in parallel so that no differences can occur here.

The compatibility of the project files, especially for the reseller system, is retained for as long as possible.
