For those that don't particularly follow devel day-to-day, the blurb
about the XZ change is pretty uninformative. I've tried to dig back a
bit and it seems the XZ change is to pick up XZ 5.0. It seems the
rebuild was done to fix Delta RPM generation? From a package
standpoint, will that mean that F14 is incapable of reading F15 RPMs?
Does that impact mock?
The only case it hits is deltas. If you have a package that was built
in f14, and then a update happens in f15, the delta wouldn't work
right. (At least this is my understanding).
mock shouldn't be affected, nor should f14/f15 rpm read interop.
I'd be happy to flesh out the change a bit more in detail if
someone
could point me at what is really changing in terms of XZ compression
and what it means going forward. Better late than never.
Yeah, I wish I could find a good cite...
Perhaps the deltarpm and/or xz maintainers could chime in with the
exact info.
