QEMU 2.1 should be released two months from today and with it will come ARM architecture improvements and other enhancements.
QEMU 2.1 just passed the mid-point in its development cycle with the release being planned for a 29 July debut. The soft-feature freeze is expected to happen in mid-June, the hard feature freeze at the start of July, and then three release candidates before the official release. The QEMU 2.1 schedule is available via the QEMU Wiki
Among the features to be found in QEMU 2.1 include improved Allwinner SoC emulation, more complete AArch64 handling, USB support for file-sharing via MTP emulation, mouse wheel support for the SDL 2.0 interface, and many other changes. QEMU's Tiny Code Generator (TCG) also has improvements to AArch64, Alpha, IA64, and SPARC back-ends. More information on the tentative QEMU 2.1 changes are also available via the project site
