Note that at this point; our NTFS driver lacks caching (which causes inferior performance), journaling and security support; with potentially undiscovered bugs. Still, read/write support is greatly enhanced! NTFS boot support was added into FreeLoader in 2022.

USB 3 on #ReactOS? Justin is brewing it ^^
Show casing this a bit more! The new Windows 11 compatible UCX stack. It’s a USB3 stack that even is compatible with the USB4 routers and companion drivers. Going to PR this to the main @reactos repo soon! But I’ve been using this on my win11 install since it’s a little more stable than window’s normal stack.

Our developer @MishaTheCoder has recently imported SYMCRYPT library from Wine. Along with better support for kernel-mode cryptography (needed for many NT6+ APIs), this will enable future WPA/WPA2 support!
