Not at all. The usage of the T-Flag for dealing with
interrupts is part of the code for a very long time
(versions around 0.9). It is even documented since ever ;)
What's new, is that there is now an example for the
interrupts..

1st Options is yours. All of the CPU is mine, with the
(documented) exception of the temp registers. They can be
used without restriction, but they are not kept between
two words however.
