So, if you are talking about updates in the projects according to the new technologies that emerge in the industry then I would say there is one project where earlier the technology that was used was a 90s framework and since there wasn't any major update for that after one last release a few years ago we had to update it to a more sophisticated platform or framework that provided better solution to our problem. So, the problem was UI and the software was Tkinter. There aren't any major updates in Tkinter so we updated to PyQt and PyQt is complete in itself for smaller grade applications. It can also be used for larger grade applications but our use case was smaller.
