Below, some changes.

 System emulation

Incompatible changes

   • The handling of the floppy device controller is different between
     <2.4 and >=2.4 machine types that use the Q35 chipset (e.g. "-M
     pc-q35-2.3" vs. "-M pc-q35-2.4"). This can cause problems if you
     are defining floppy drives with command-line options such as
     "-global isa-fdc.driveA=id.
   • The ARM 'virt' board default interface type has changed from IDE to
     virtio. This means that some incorrect command lines that we
     previously silently accepted will now fail with an error message
     like "qemu-system-arm: -drive file=img.qcow2,id=foo: Drive 'foo' is
     already in use because it has been automatically connected to
     another device (did you need 'if=none' in the drive options?)". As
     the error message suggests, you should add "if=none" to the -drive
     option to fix this.


 GUI

   • Support for OpenGL-based display rendering in the SDL2 and GTK+
     backend. This is preparatory work for 3D acceleration.
   • Improvements to the Cocoa front-end, fixing full-screen mode and
     adding a list of consoles to the View menu.
   • The two extra keys in Brazilian 107-key keyboards are now usable.


 Audio

   • Obsolete audio backends have been removed: esd (superseded by
     pulseaudio), winwave (superseded by dsound), fmod (not compatible
     with the GPL)

Ken is have many problems with this version, described in some posts in -dev and latest at

​http://lists.linuxfromscratch.org/pipermail/blfs-support/2015-August/076948.html

I'm reopening, to propose reverting to previous version.

I asked on one of the qemu lists (the one to which I am still subscribed) and PMM pointed my to a different list and said that if qemu brings the box down than it is a kernel problem, which is of course correct. Today I installed linux-4.2.0-rc8 and kept qemu-2.3.0 running (idle, apart from xscreensaver) for a bit over 3 hours. My guess was that 3 hours would be enough to trigger the problem with qemu-2.4.0. Came back and the screen was blank (powered off after no activity) and the box was responsive.

So, not a qemu-2.4.0 problem, I just failed to hit it with 2.3.0 in earlier usage.
