Still unfixed in master

Nothing, hurrah!

Fixed in rc1

• Compile failures if libnfs is enabled
• net/netmap.c broken on FreeBSD [1]
• don't use 8-byte atomic access on 32-bit platforms (fixes freebsd, ppc32, etc)
• ensure chardev socket backends are in non-blocking mode [2]
• cannot connect resolve client hostnames on FreeBSD [3] (broken since 2.4.0 by commit 3de3d698d942d1116152417f882c897b26b44e41)

Fixed in rc2

• add i82801b11 missing migration data
• tests/bios-tables-test: fix assert (make check will fail for newer iasl without it)
• reentrancy problems for dataplane/aio (fixed in pull 8227e2d16705b8c94df93f465d4e1659c28c69ce)
• compilation failure when --enable-tcg-interpreter is used (Stefan Weil has patch posted)

Fixed in rc3

• Networking is broken on Windows hosts
• pflash block/io.c bdrv_co_do_pwritev during migrate (typically EFI setup)
• NBD features added in 2.6 don't quite follow protocol [4] [5]
• buffer overrun in cadence_uart
• cuda: fix off-by-one error in SET_TIME command [6]
• Update language files in po/. As there were changes in ui/gtk.c, the line numbers need an update.
• gluster data corruption after io errors
• fix pv-grub booting with xenfb [7]
• wrong r0 on kernel boot on raspi2/xilinx-zynq/highbank/midway
• TCG performance 15% regression due to assert()

Will be fixed in rc4

• nbd: Don't mishandle unaligned client requests
• performance regression since 2.4 on AArch64 due to not using transparent huge pages
• While committing snapshot qemu crashes with SIGABRT [8] (wants 'block: Fix assertion failure at mirror exit' series)

Not planned to be fixed for 2.6

• compilation failure on 3.20 gtk (fedora 24) - deprecated functions (not a failure for release tarballs, workaround for building from git tree is to use --disable-werror; we will fix this in 2.7)
• iscsi: cannot associate -drive driver=iscsi with -iscsi args to get authentication credentials when iSCSI IQN contains a ':' (which essentially all of them do). Needed to fix CVE-2015-5160 in libvirt https://lists.gnu.org/archive/html/qemu-devel/2016-04/msg03387.html
