At this point, changes like you experienced should be the exception.
But, occasionally they will happen. We really try to document them when
they occur but this relies on those of us who make the changes making
adequate note about them.
When the version jumps to 1.1, then there may be more incompatibilities
but they should be documented.
Thanks for the note and the reminder.
