Thanks @carlfink you make a good point (more later in the post for you). In this case we made a decision to improve a feature. If this does not improve your published content please help us understand your experience. This change provided what we perceived as a better experience for the screen-readers and environments we test with.
It also allowed for a frequently requested feature to be implemented (reading initially hidden text from text blocks, buttons, and shapes when shown).
We request your feedback by telling us how this change:
a) breaks your content or your content’s compliance
b) provides a less preferable experience
c) causes you unwanted rework
We appreciate your feedback and help in improving Lectora. And Carl, we are working on some in application guides that will notify users that something has changed. In this case we really should notify authors when they load an accessible title that the Aria attributes, Alt tags, and Title tags changed for Text, Buttons and Shapes, I absolutely agree with your pet peeve.
