Note that your module is making heavy use of the unpublished internal
details of the perl runtime engine. You might want to add a caveat to the
pod that this this module might irretrievably break in some future release
of perl.
The merge commit which made all the changes is
9d876b687d12d77fcb1012f1b865783476f00c7a,
with the 204 commits from d4ce758 onwards being the actual changes.
The email thread starting at
http://nntp.perl.org/group/perl.perl5.porters/233631
contains the announcement, with a long description of what changed.
It also added a section to perlguts,
head1 Dynamic Scope and the Context Stack
which describes how the new (but not the old) system works.
That merge made so many changes to the detail of scope entry/exit that I'm
don't feel comfortable advising on how to make code work with the older
buggy system.
