Not so much fear as concern. One of my rules is that the good will take
care of itself it is the bad you have to plan for. In this case it is
not the nine changes that do not impact your code but the one that does.
When going through the change logs the incompatibilities are listed at
the top under the Migration to Version 9.* header. It does not take to
long to double check. If you want to save time just look at the major
version changes, i.e 9.X versus 9.X.x as incompatibilities are allowed
in major version changes. Not that they do not happen in minor releases,
but that is generally done to fix a security/major bug and I do not
recall any in the range you are looking at.
