After being stuck for a long time on version 3 of BCU, adding small improvements and fixing problems, it's finally time for a bigger update with changes to the interface.
- As you've probably noticed, there is something new under the application list - a treemap that shows installed applications by size. You can hover and click on the tree map, and it will act as if you clicked on the application list.
- Another change is the uninstallation dialog - now when you click uninstall, BCU will show a step-by-step dialog.
- All silent deinstallers will now be automatized, so if something goes wrong and a message pops up, uninstallation won't get stuck anymore.

## Thank you for all the support!

Thank you to everyone who donated, translated, tested, shared, or otherwise supported BCU this year! Without your help, feedback and support progress on BCU would be much slower, or even stop completely.

Your support helped me release new versions (relatively) regularly and let me buy software and hardware that greatly helped with the development. (Code signing certificate, more RAM to run tests in virtual machines, hosting etc.)

And for this, I wish everyone who uses BCU happy Christmas and a happy new year!
