Release notes:

New Release
Arrange memory device allocation so that it is possible to allocate up to about 3900MB of memory instead of 3500MB. (joncampbell123).
Fix S3 LFB PCI base alignment error if system memory pushes it to a higher address (joncampbell123).
Fix EGA 640x350 4-color mode (when EGA memory size is 64KB) to display correctly. Prior to this fix, 640x350 4-color only worked properly if the INT 10h Video Parameter Table was enabled. (joncampbell123).
Fix S3 VGA memory size reported through register CR36 to cap at 4MB and set the value correctly. This fixes a known issue where setting vmemsize to 8MB caused Windows 98 to report memory size as 2.5MB. (joncampbell123).
Fixed a problem when VZ Editor is resident in PC-98 mode. (nanshiki).
INT 10: SVGA mode 0x6A does not exist on plain VGA hardware. (joncampbell123).
INT 10: Fix mode 0x6A (800x600 4-color SVGA) to use a correct dot clock so that the refresh rate is >= 60Hz instead of 37Hz, and make sure mode 0x6A is a 100% clone of VESA BIOS MODE 0x102. (joncampbell123).
Fix MMX/SSE instruction decoding, correct some mistakes in MMX emulation. (joncampbell123).
IMGMAKE: Add -partofs option to allow control of where the partition begins in the image (joncampbell123).
IMGMAKE: Add -align option so that the FAT filesystem can be arranged for more optimal I/O on devices with larger sectors, such as modern 4096-byte/sector drives. (joncampbell123).
IMGMAKE: Add -label option so that the generated FAT filesystem has the specified volume label. (joncampbell123).
MDA emulation: Fix non-blink attributes 0xF0 and 0xF8 to correctly render bright green background. (joncampbell123).
Fixed crash when a CD image was loaded to an "empty" drive (maron2000)
Log loaded .conf file (maron2000)
Supress redundant screen reports in log (maron2000)
Fixed mouse capture locking by middle button (maron2000)
Fixed toggling the menu option "Autolock mouse" did nothing (maron2000)
Fixed build failure with libc++ 19 (DimitryAndric)
Fixed ful
