OS/2 installer no logner locks up on splash screen on PS/2 Model 70 and 80, fixes #400.
Fixed several Amstead bugs, GEM no longer crashes on the Amstrad 1640, fixes #391.
Ported John Elliott's Amstrad fixes and improvement from PCem, and fixed the default language so it's correctly Engliish, fixes #278, fixes #389.
Fixed a minor IDE timing bug, fixes #388.
Fixed Toshiba T1000 RAM issues, fixes #379.
Fixed EGA/(S)VGA overscan border handling, fixes #378;
Got rid of the now long useless IDE channel 2 auto-removal, fixes #370;
Fixed the BIOS files used by the AMSTRAD PC1512, fixes #366;
Ported the Unicode CD image file name fix from VARCem, fixes #365;
Fixed high density floppy disks on the Xi8088, fixes #359;
Fixed some bugs in the Hercules emulation, fixes #346, fixes #358;
Fixed the SCSI hard disk mode sense pages, fixes #356;
Removed the AMI Unknown 386SX because of impossibility to identify the chipset, closes #349;
Fixed bugs in the serial mouse emulation, fixes #344;
Compiled 86Box binaries now include all the required .DLL's, fixes #341;
Made some combo boxes in the Settings dialog slightly wider, fixes #276.

Finished the 586MC1;
Added 8087 emulation;
Moved Cyrix 6x86'es to the Dev branch;
Sanitized/cleaned up memregs.c/h and intel.c/h;
Split the chipsets from machines and sanitized Port 92 emulation;
Added support for the 15bpp mode to the Compaq ATI 28800;
Moved the MR 386DX and 486 machines to the Dev branch;
Ported the new dynamic recompiler from PCem, but it remains in Dev branch until after v2.00;
Ported the new timer code from PCem;
Cleaned up the CPU table of unused stuff and better optimized its structure;
Ported the Open-XT and Open-AT from VARCem, the Open-AT is in the Dev branch;

Added the AHA-1540A and the BusTek BT-542B;
Moved the Sumo SCSI-AT to the Dev branch;
Minor IDE, FDC, and floppy drive code clean-ups;
Made NCR 5380/53C400-based cards' BIOS address configurable;
Got rid of the legacy romset variable;
Unified (video) buffer and buffer32 into one and make the unified buffer 32-bit;
Added the Amstead PPC512 per PCem patch by John Elliott;
Switched memory mapping granularity from 16k to 4k (less than 1k not possible due to internal pages);
Rewrote the CL-GD 54xx blitter, fixes Win-OS/2 on the 54x6 among other thing;
Added the Image Manager 1024 and Professional Graphics Controller per PCem patch by John Elliott and work done on VARCem;
Added Headland HT-216, GC-205 and Video 7 VGA 1024i emulation based on PCem commit;
Implemented the fuction keys for the Toshiba T1000/T1200/T3100 enhancement;
Amstrad MegaPC does now works correctly with non-internal graphics card;
The SLiRP code no longer casts a packed struct type to a non-packed struct type;
The Xi8088 and PB410a no longer hang on 86Box when PS/2 mouse is not present;
The S3 Virge on BeOS is no longer broken (was broken by build #1591);
OS/2 2.0 build 6.167 now sees key presses again;
Xi8088 now work on CGA again;
86F images converted from either the old or new variants of the HxC MFM format now work correctly;

Further improved the 808x emulation, also fixes the noticably choppy sound when using 808x CPU's, also fixes #355;
OS/2 installer no logner locks up on splash screen on PS/2 Model 70 and 80, fixes #400.
Fixed several Amstead bugs, GEM no longer crashes on the Amstrad 1640, fixes #391.
