01History
KTechLab was first developed by David Saxton, who worked on it until 2007. The design ideas and a lot of the current code have been developed by him. He released various versions, up to version 0.3.6.
When David Saxton stated that he would not be able to continue developing the software, KTechLab stalled for a while before others continued his work, releasing version 0.3.7, with more components and bug fixes.
In January 2019, KTechLab was ported to Qt and KDELibs4. The new priority changed to port KTechLab to Qt5 and KF5, accomplished by version 0.50.0.
