Upgrading to version 4

Hi community I need your help again,
We are using the 3.15 version, our forms and tests need to be reviewed to get forms validated and tests passed
If we modify the forms and tests in order to get them passed with version 4 I’m pretty sur that the modified forms and tests will work also in 3.15
could you confirm this point ?

In general the answer is yes, it is possible (and intended) to have a config that works with both 3.15 and 4.x. The main caveats to that are:

  • You cannot use newer features (that only exist in 4.x)
  • There are some known differences in form behavior, mostly affecting very specific edge cases. Still, basically all the required changes can be done in a way that remains backwards compatible with 3.x.
