Changes between release 0.4.3 and 0.4.4 include, among other things:
o) The interrupt subsystem has been redesigned. This means two things:
x) Internal code cleanup, which makes the whole emulator more
maintainable. Instead of using magically encoded integers
for interrupts, strings are now used. These strings are in
the form of "paths", so that devices and busses can more
easily be connected to other busses, devices, or CPUs.
x) Some machine types which happened to work in release 0.4.3,
but were not listed in the documentation as working, may
have stopped working now. As always, the documentation should
indicate the combinations of machine modes and guest OSes that
are supposed to work.
o) SuperH (SH4) emulation is now somewhat more stable, enough to let a
NetBSD/dreamcast Live CD be usable.
o) PowerPC "G4" emulation is now stable enough to let NetBSD/macppc
run from a disk image. (Installing actually worked before, but the
NetBSD/macppc GENERIC kernel uses AltiVec instructions which were
not implemented correctly.)
o) The PICA-61 (arc) and i80321 (evbarm) emulation modes now have their
timers fixed at 100 Hz. A hardcoded speed like this is very ugly, but
it is at least better than before (when the timer wasn't really
running at any specific speed at all).
