14 Detailed change log :
15
16 - CPU
17 - Support of XSAVE/XRSTOR CPU extensions, to enable configure with
18 --enable-xsave option
19 - Support of AES CPU extensions, to enable configure with
20 --enable-aes option
21 - Fixed Bochs failure on RISC host machines with BxRepeatSpeedups
22 optimization enabled
23 - Implemented SYSENTER/SYSEXIT instructions in long mode
24 - More than 100 bugfixes in CPU emulation correctness (both x86 and x86-64)
25 - MenuetOS64 floppy images booting perfect again !
26 - Updated CPU instrumentation callbacks
27
28 - Bochs Internal Debugger and Disassembler
29 - Added memory access tracing for Bochs internal debugger, enable
30 by typing 'trace-mem on' in debugger command line
31 - Many bug fixes in Bochs internal debugger and disassembler
32
33 - System BIOS (Volker)
34 - Implemented LBA48 support
35 - Added generation of SSDT ACPI table that contains definitions
36 for available processors
37 - Added RTC device to ACPI DSDT table
38 - Added implementation of SMBIOS
39
40 - I/O devices (Volker)
41 - VGA
42 - Implemented screen disable bit in sequencer register #1
43 - Implemented text mode cursor blinking
44 - Serial
45 - new serial modes 'pipe-server' and 'pipe-client' for win32
46 - new serial mode 'socket-server'
47
48 - Configure and compile
49 - Fixed configure bug with enabling of POPCNT instruction, POPCNT
50 instruction should be enabled by default when SSE4.2 is enabled.
51 - Removed --enable-magic-breakpoint configure option. The option is
52 automatically enabled if Bochs internal debugger is compiled in.
53 It is still possible to turn on/off the feature through .bochsrc.
54 - Allow boot from network option in .bochsrc
55 - Added Bochs version info for Win32
56
57 - Display libraries
58 - implemented text mode character blinking in some guis
59 - improved 'x' gui runtime dialogs
