Hello again Morten,
I did mean small in number of code change, which I
tried to make clear from the rest of the email, but
as discussed below, I also think the PDB occupancy
change was also small in terms of behaviour.

Almost any change impacts the user in some way.
I still feel this was a minor change (although of
course important to some, including you). This is
parsing of malformed PDF files where the user
ALREADY gets a warning (or error in strict mode,
where there would be no functional change) that
there is a problem with the occupancy data.
One reason why I specifically talked about small
commits (in the sense of a simple diff) above is
they are trivial to revert if the need arises, or as
in this case, modify:
This change was suggested and supported by
people who've been actively contributing to the
Biopython structural module for some time, so I
had reason to trust their good judgement, and as
I wrote at the time there was a clear consensus
with three people in all happy with the idea:
Changes where there isn't clear agreement are
generally discussed over a longer time period.
Note that Biopython is already relatively strict
about not breaking things and preserving backwards
compatibility (to the point where it does delay new
features). We do care about not breaking existing
scripts without warning - so when people speak up
on the list that something is likely to cause them
trouble, we do listen.
Is that any clearer?
