zref-abspage and perpage incompatibility

Yes, I know it already and have prepared version 3.0 of zref. In zref-abspage I rename the counter to zabspage. Also I take the opportunity of the major version step to change the way, the counter is increased. Before version 3.0 the counter is increased during shipout time via \AtBeginShipout, that means that in the output routine the counter is not yet updated to the value for the page like counter page. With version 3.0 the counter zabspage shows to the next page number and it is increased after the shipout like the behaviour of counter page.

Because I have not finished the work on other parts of the bundle, the next release of my bundle will be later in the year.
