Default kdbx version

[nicoursi]

Hi, i noticed that if i create a new database with keepassDX it'll be kdbx3.1, but if I modify it with keepassXC it becoms kdbx4.1 and keepassDX can access and modify it correctly.

My question is why, if DX can work with 4.1 format, doesn't use it as default, or at least allow to choose the format?

It just respects the conditions of the official website. It allows to make the database file compatible with more clients. As the transition from 3.x to 4.x is based on specific data, there is no point in upgrading to 4.x if these specific data are not present in the database.
