I was out most of today, so this is a few hours later than usual, but there it is, the normal weekly rc. "Steady progress towards 4.4".
The changes look fairly normal: just under 60% driver updates (of which almost half is GPU updates, this time mainly skewed due to some nouveau firmware update patches), about 25% arch updates (mostly arm, but some changes in x86, s390, powerpc, nios, mips, m68k, arc..), and about 10% filesystem updates (mostly btrfs and nfs). With the rest being "misc" (mainly header files).
The appended shortlog gives some overview of the details. I don't think there's anything particularly exciting, although that obviously depends on whether some particular issue ended up affecting you or not. Most of it is pretty tiny random fixups.
