Changes in 2.6.5 (June 1, 2014):

Brief summary :
- CPU: extra 5-10% emulation speedup with new trace linking optimization
- CPU: implemented new instructions (e.g. AVX-512, SHA, XSAVEC)
- CPUDB: added 2 new CPU models
- Bugfixes for CPU emulation correctness (including some critical ones)
- Gui debugger output window now can be used as a log viewer
- Added built-in slirp (user-mode networking) support (ported from Qemu)
- Added global sound config option and volume control support to the devices
- Added new experimental gui 'vncsrv" using the LibVNCServer library
- Rewrite of the bximage utility in C++ for image creation, conversion and resize

Detailed change log :

- CPU
- Bugfixes for CPU emulation correctness (critical fixes for XSAVE, VMX, TBM/BMI and RDRAND instructions)
- Implemented FCS/FDS Deprecation CPU feature
- Implemented SHA instructions emulation
- Implemented XSAVEC instruction emulation and XINUSE optimization in the XSAVEOPT instruction
- Implemented AVX-512 instructions emulation (experimental)
! CPUDB: Added Intel(R) Core(TM) i7-4770 CPU (Haswell) configuration to CPUDB
! CPUDB: Added AMD A8-5600K APU (Trinity) configuration to CPUDB

- Replace 'SSE' and 'AVX' .bochsrc option with single 'SIMD' option which controls presence
of all CPU SIMD extensions from SSE to AVX-512

- Extra 5-10% emulation speedup with new trace linking optimization. The optimization
is enabled by default when configuring with --enable-all-optimizations option,
to disable trace linking optimization configure with --disable-trace-linking.
The optimization require to compile Bochs with at least -O2 optimization level on gcc.

- Bochs Debugger and Instrumentation
- Added disam for Bochs internal instruction representation, especially useful for instrumentation
- Updated definition of instrumentation callbacks, see description in
instrumentation.txt / Fixed instrumentation examples
- added capability to use the gui debugger output window as a log viewer

- General
- Increased max. device log prefix size to 6 and added / modified prefixes
- plugin version now uses the native DLL handling code for all Windows ports
- critical bugfixes in save/restore functionality

- Configure and compile
- configure and compilation fixes for Cygwin and Visual Studio environment
- configure option --enable-cdrom now only controls the presence of
platform-specific code for device access
- building plugin version with MSVC nmake now supported

- Config interface
- Added global sound control option for the driver and wave input/output
- Added new bochsrc option to control the speaker output mode
- Added support to specify the initial time for 'clock' option in ctime(3) string format
- Added support for the LTDL_LIBRARY_PATH variable with MSVC plugins
- All SB16 / ES1370 options are now changeable at runtime
- textconfig: added menu item for saving configuration at runtime
- Added bochsrc option for the Voodoo Graphics emulation (experimental)

- I/O Devices
- Hard drive / CD-ROM
- seek latency implemented for ATA/ATAPI read commands
- portable ISO image file access now available on all platforms
- Networking
- added built-in slirp (user-mode networking) support (ported from Qemu)
- removed the "slirp backend" support (required external slirp binary)
- slirp/vnet: all supported TFTP extension options implemented now
- Sound
- SB16 / ES1370: added volume control support for wave output
- SB16: fixed audio distortion when playing stereo wave files
- ES1370: added 'wavemode' support similar to the SB16
- soundwin: added capability to specify the ID of the MIDI device to use
- Serial
- Serial mouse detection fixes
- Busmouse
- Non-functional device rewritten to make it work in DOS and Win95 guests
(use --enable-busmouse to configure and "mouse: type=bus" at runtime)

- ROM BIOS
- PS/2 mouse function: allow setting mouse packet size to 4 for wheel support

- GUI and display libraries
- Added new experimental gui 'vncsrv" using the LibVNCServer library
- RFB: set maximum resolution to 1280x1024 (same as vncsrv)
- RFB: don't wait for client connection on startup if timeout is set to 0
- Added mouse wheel support to the rfb, vncsrv and wx guis
- wx: added viewer window for the Bochs log output
- win32: fixes and improvements for the fullscreen mode

- Tools
- bximage utility rewritten in C++ for image creation, conversion, resize
and redolog commit. Now vmware4 and vpc images can be created.
