The configuration and CPU subsystems were reworked, allowing you to enable or disable CPU options at runtime through .bochsrc. Bugs were fixed for CPU emulation correctness and stability. X2APIC extensions were implemented. Intel VMXx2 extensions were implemented. New features include Extended VMX capability MSRs, APIC Virtualization, X2APIC Virtualization, Extended Page Tables (EPT), VPID, Unrestricted Guests, and new VMX controls. The PCLMULQDQ AES instruction was implemented. The Bochs internal debugger functionality was extended. USB HP DeskJet 920C printer device emulation was added.
此版本修正了在wxWindows的可能段错误，在CD - ROM read_toc（）函数为* BSD的，从CD启动为NetBSD的光盘，在CMOS校验和“刷新位”在场内的行为。它还修正。bochsrc解析，显卡调整/重绘问题，编制的问题，在IRIX和Tru64，一些MMX公司/上证所的错误，并在仪器的错误。

Minor bugfixes
This release fixes a possible segfault in wxWindows, the CD-ROM read_toc() function for *BSD, booting from CD-ROM for NetBSD, the CMOS checksum, and the "refresh bit" behaviour in pit. It also fixes .bochsrc parsing, VGA resize/redraw problems, compilation issues on Irix and Tru64, some MMX/SSE bugs, and bugs in instrumentation.
This release features a speedup for the emulation by 2x, and new plugin devices and GUIs. Now you can compile with many more options, and choose between them at runtime. Emulation of AMD x86-64, MMX, SSE, and SSE2 instructions was added, along with a wxWindows port and an SVGAlib port. There are improvements to many I/O devices: Bochs now supports up to 8 hard disks/CDROMs, a TUN/TAP network interface, and 360k floppies. The MacOSX/Carbon interface was improved and the MacOS9 port was updated. The GDB remote stub allows symbolic debugging with Bochs simulation.
