It will be one of the X/Y releases, like 12.3(7)XI.

The 2nd CPU doesn't help to scale the control plane, so you are still
limited to 2-16k sessions depending on your CPU type. However, the
data plane forwarding performance has increased, so if you were CPU
limited because of your traffic profile, you will probably be able to
increase the number of sessions you can terminate for a given traffic
pattern.

So say you had a NPE-G1 which could do 100kpps of L2TP traffic and
your users averaged 20pps. The NPE-G1 could do 16k sessions, but the
CPU would only support 5k sessions before maxing out. Say we doubled
the performance with MPF to 200kpps, then theortically, you could do
10k sessions at 20pps each. BTW, I don't really know how much
improvement we are publicly advertising in regards to MPF, so I don't
want to set the wrong expectation. I guess you'll know soon enough. :)
