*introduced

But I agree w/ Erik, this is the same as the following.

This is all for the Resource Control util subsystem. Essentially a way
to monitor the Cache and Memory Bandwidth and provide capabilities to
know what type of data points are available through the domain capabilities.

FWIW:

IDC - but I guess a long time ago I got conditioned to not supply
news.xml articles for every bz fixed. I'd be more inclined to just drop
this one especially since nwfilter binding is so new, but I'm also fine
with noting it.

This is all about LUKS encryption... Prior to 4.5 encrypted volumes was
supported though - so I'd be careful to note a version. The 4.5 change
was to "fix" the code in order to handle the multi-step processing that
qemu-img now needs to encrypt a LUKS volume. At best this is a we're now
allowing the input volume to be encrypted.
