Hi,
the kernel 4.3 was released yesterday, the btrfs-progs will follow at the end
of this week. I've tagged an rc1 from current devel branch. There are a lots of
small invisible changes and one change in the defaults:
* mkfs: mixed mode is not forced anymore for devices smaller than 1 GiB
I've updated manual pages for mkfs, balance, btrfstune, convert and inspect,
I'd be glad if somebody could proofread them.
Otherwise bugfixes and small-sized patches are still welcome.

It says one change in the /defaults/, but then it says mixed mode isn't
/forced/ anymore under a GiB.
Which is it, a change in the /defaults/, under a gig now defaults to
separate data/metadata, or same /defaults/, but now there's a way to
overrule them and do separate data/metadata under a gig, so while mixed
remains the default, it's no longer /forced/?
If the /defaults/ changed, is mixed mode still /recommended/ for small
filesystems?

Well, it may be a loose definition of 'default'. I meant a change in the
current behaviour without further tuning.

Yes it is, where small remains < 1 GiB.

Thanks. Useful information, now more important to know than ever, since
it's no longer the under-a-gig no-additional-options default.

Why?
If it's still recommended to use mixed for small device, why not keep
it the default and just permit the user to manually specify something
else?

I think the reasoning here is that leaving it as the default would
require adding another option (possibly, I don't know if -O !mixed-bg
works to override the default). Of course, properly educating people
that they should be using this on small devices is going to be a much
longer and more involved task than just adding an option...
