Part of tools/blktap. Nothing exciting looking under there.

Parts of tools/blktap2.

24800:acf4ad70c87b "blktap2/libvhd: Build shared objects using -fPIC"
might be interesting?

23055:a73a35527763 "tools: link each shared library or binary only
against the libraries it uses" might be an ABI visible change?

The rest look like uninteresting build system tweaks and the odd fix.

tools/libfsimage/, nothing jumps out.

Newly installed in 4.2, 23075:b4351d57464b

>         libxenstore.so.3.0 -> libxenstore.so.3.0.1*

tools/xenstore contains 24376:32a3d86ae4a4
"libxenstore: Provide xs_check_watch" and 24507:19a0a2e26137 "xenstore:
New function xs_path_is_subpath"

tools/libvchan is new in this release

23619:77a235e95b47 "libxl: disks: new xlu_disk_parse function"

I did the above comparisons with 
        hg log -r 4.1.0-branched:tip <paths>

Looks like we wanht to bump libxenstore and libxlu.

Possibly the blktap2 ones too, but they are pretty internal I guess.

Don't we switch QEMU_TAG to point to the tagged name instead of a SHA
sum?

Yes, all my talk of rc0 was just me not checking what we've done before.
It's rc1 all the way.
