What’s new for FreeBSD 11

Overall system / architectural changes

(architecture as in “the overall design of the system”, not in the sense of “ARM vs x64”)

  • Improved NUMA support

  • Improved support for blacklisting bad memory locations

Tool chain

  • Support for C blocks imported from Apple GCC

  • ELF tool chain tools addr2line, elfcopy, nm, readelf, size, strings

Kernel, hardware support & other low level improvements

  • LIBCOMPILER_RT has replaced LIBGCC on all platforms
