  * Clang is the default compiler (GCC is also supported)
  * NetBSD C library 
  * ELF is the default executable format
  * Asynchronous, multithreaded virtual filesystem (VFS) server
  * Experimental SMP support
  * FUSE support (GSOC project by Evgeniy Ivanov)
  * NetBSD password file format (part of GSOC project by Vivek Prakash)
  * FS types infrastructure:
    * Use a proper /etc/fstab file
    * Clean/unclean FS flag in MFS
    * Full base system ext2 integration: newfs, fsck, can install on ext2
    * Do proper ''''fsck -p'''' on each boot for all fstab-listed filesystems
  * NetBSD bootloader
  * Smaller boot images (using gzip)
  * ProcFS: /proc file system
  * Multithreading and NCQ support in the AHCI driver
  * Debugging Improvements
    * GDB and core dump support (GSOC project by Adriana Szekeres)
    * Block device tracing
  * New NetBSD userland utilities (part of them as a GSOC project by Vivek Prakash)
    * ext2 fsck&mkfs, gzip, m4, man&tools, mkdep, mkdir, mkfifo, mktemp, rm, rmdir, tic, uniq
    * libcurses, libcrypt, libprop, libterminfo, libutil
    * bzip2, date, indent, mdocml (mandoc), sed, zoneinfo ports
  * Better reliability
    * Transparent recovery from block device driver crashes in file systems
    * Transparent retry upon failing block device I/O in file systems
    * New Faulty Block Device fault injection driver
    * Servers and drivers run as unprivileged users
    * Fix all (potential) bugs found by Clang's more elaborate warnings
  * Better virtualization support
    * Added libvassert, to enable easier support for VMWare VAssert
    * New VirtualBox time sync driver

==== Other important differences ====
  * The MINIX project now uses ''git'' as its version-control system

==== Known Issues ====

  * VirtualBox: Minix cannot be installed w/o hardware acceleration support (VT-x, AMD-V)
    * Workaround: See [[.:usersguide:runningonvirtualbox|RunningMinixOnVirtualBox]]
  * Build warnings: Clang has much better diagnostics than ACK, so clang reports more warnings on the MINIX codebase. These warnings are being fixed over time.
  * Clang performance: On MINIX, clang builds more slowly than GCC. We are working on this. In the meantime, you have the option to build MINIX with GCC (CC=gcc).
