New Update Rufus 4.x changelog updates

Rufus 4.8 BETA​

  • Switch to wimlib for all WIM image processing:
    • Greatly speeds up image analysis when opening Windows ISOs
    • Can speed up Windows To Go drive creation (But won't do miracles if you have a crap drive)
    • Might help with Parallels limitations on Mac (But Rufus on Parallels is still unsupported)
    • Enables the splitting of >4GB files with Alt-E (But still WAY SLOWER than using UEFI:NTFS)
  • Switch to using Visual Studio binaries everywhere, due to MinGW DLL delay-loading limitations
  • Add more exceptions for Linux ISOs that restrict themselves to DD mode (Nobara, openSUSE, ...)
  • Improve reporting of UEFI bootloaders in the log, with info on the Secure Boot status
  • Fix an issue with size limitations when writing an uncompressed VHD back to the same drive
  • Fix a crash when opening the log with the 32-bit MinGW compiled version
