Linaro QEMU 2014.01 is the latest release of qemu-linaro. Based off upstream (trunk) QEMU, it includes a number of ARM-focused bug fixes and enhancements.
This release has been updated to be based on upstream's recent 1.7.0 release. Interesting ARM related upstream changes include the addition of experimental virtio device support in the vexpress-a9 and vexpress-a15 boards, and a new TCG target for emulating other CPUs on AArch64 host systems.
Note that unless you require any qemu-linaro specific features (the only current such feature is OMAP3 board emulation) it is likely you will be better served by upstream's releases than by the Linaro QEMU releases currently.
