Is the current bug fixing leading upto 3.0.3 still taking place on the
xen-unstable.hg tree, or has it branched & moved to another tree now ?

The 3.0 tree listed on xenbits doesn't seem to have any recent updates


But xen-unstable.hg is receiving major changes that we really were not
expecting for a tree that is in freeze state. For example, the following
changeset that went into xen-unstable at the weekend will likely break
compatabilty for libvirt in quite a major way


  "Replace dom0_ops hypercall with three new hypercalls:
    1. platform_op -- used by dom0 kernel to perform actions on the
       hardware platform (e.g., MTRR access, microcode update, platform
       quirks, ...)
    2. domctl -- used by management tools to control a specified domain
    3. sysctl -- used by management tools for system-wide actions"

Is this change going into 3.0.3, or is xen-unstable now reflecting the
development for 3.0.4 ?  We've got the means to support this new format
for hypercalls in libvirt, while keeping compatability for old API 
(detectable at runtime), but if its not going to 3.0.3 we can postpone 
this dev work...
