This is an important update. We know some of our customers have been using our software on every day basis during the past 10 or even 15 years. Some of the customers already retired and their children continue to run the business.
The databases grew in size. On some windows like Orders or Clients the software may display the lists quite a long time (up to several seconds).

With this update we did a major update of our internal library used for database access. And we did many speed optimizations on the windows with long lists of data. As the result the speed of displaying Orders, Clients and other such windows may be in increased 5 or even 10 times. You may not notice the speed increase on small databases. But it will be really visible on large databases. The speed increase will be also noticeable on computers working in network with two or more computers are working on the same database.
Therefore we encourage every user to upgrade into the latest version.
