The NEWS file says:
** Only one of the beginning or end of an invisible, intangible region is
considered an acceptable value for point; which one is determined by
examining how the invisible/intangible properties are inherited when new
text is inserted adjacent to them. If text inserted at the beginning would
inherit the invisible/intangible properties, then that position is
considered unacceptable, and point is forced to the position following the
invisible/intangible text. If text inserted at the end would inherit the
properties, then the opposite happens.
Thus, point can only go to one end of an invisible, intangible region, but
not the other one. This prevents C-f and C-b from appearing to stand still
on the screen.
I'm not sure what it refers to, and I think it should make it more
clear in which way it's different from the previous behavior.
Also I'd like to add the following (although better working would
be appreciated), which is about a different feature (AFAIK). Any
idea how to make the two more understandable, especially w.r.t
each other ?
** The code that forced point to move out of images and composition
has been generalized to apply to overlays as well and to invisible text.
This makes it generally unnecessary to mark invisible text as intangible,
which is particularly good due to the fact that the intangible property
can often have unexpected side-effects because the property applies
to everything (including `goto-char', ...) whereas this new code is
only run after post-command-hook and thus does not care about intermediate
states.
