We just released the new 4.0.5 of PDFsam Basic, you can download it from the download page.
We updated the bundled jdk to the latest version 11.0.5, updated translations and fixed an issue some users where getting when launching PDFsam on Windows:
Exception in thread “WindowsNativeRunloopThread” java.lang.NoSuchMethodError: at com.sun.glass.ui.win.WinApplication.staticScreen_getScreens(Native Method) at com.sun.glass.ui.Screen.initScreens(Screen.java:412) at com.sun.glass.ui.Application.lambda$run$1(Application.java:152)
For those interested in this issue there is some discussion on Stackoverflow, the openjfx-dev mailing list and the bug report we opened.
Enjoy
