Rufus 4.9 [BUGFIX RELEASE]

• Fix downloads from https://rufus.ie no longer working due to recent GitHub server changes
• Fix unofficial Windows ISOs, with single index WIMs, not presenting the WUE dialog

Note: The GitHub issue mentioned above means that NONE of the existing versions of Rufus are able to automatically detect and update to the 4.9 release.
You MUST upgrade to Rufus 4.9 manually, even if you have check for updates enabled in Rufus... 😢

Also from Rufus 4.8:

• 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
• Fix commandline parameters not being forwarded to original Windows setup.exe
