===== Release Notes =====

==== New features ====
    * The first release with [[:developersguide:minixonarm|ARM support]], three Beagle targets ($45 boards with lots of features and power! More info on specs & where to buy [[http://beagleboard.org/|on the beagle site]]) are supported - build a complete SD card image from scratch using just our source tree and a single shell script invocation!
    * Experimental USB support for the Beaglebones (hubs & mass storage)
    * Crosscompiling for both ARM and x86 - the buildsystem is [[https://build.opensuse.org/package/show/home:beng-nl/Minix3|very portable]].
    * VND: vnode disk (loopback) block driver
    * [[:developersguide:llvmbitcode|LLVM Bitcode]] build of the system
    * Import of LLVM / clang in the sources
    * unified block cache shared by FSes and VM
    * mmap() allowing more sharing and less copying and lower memory footprint - used significantly by exec() and ld.so for all executables and shared libraries

==== Improvements ====
    * More complete source compatability with NetBSD in terms of utilities, calls, types (lots of 64-bit), toolchain, codebase and packages. All Minix-specific code is in a top-level minix/ subdir.
    * [[http://www.minix3.org/pkgsrc/logs/3.3.0/20140810-053139/meta/report.html|Updated packages overall - a big set is built now]]
    * New input infrastructure: input server and keyboard driver separated from TTY
    * Packages are dynamically linked now, so they're smaller
    * Improved driver modularity: UDS separated from PFS; PTY separated from TTY; one controller (not two) per at_wini driver; LOG no longer in the boot image
    * The messages have been given a C type per request so all the types are cleaner; and the message size is a bit bigger now so there's more room for growth with the bigger types

==== Known issues ====
  * The isofs driver has been disabled as it is too buggy. isodir, isoread, isoinfo, writeisofs can be used instead.
  * X11 is not available currently. Our old version, which was still based off of a monolithic XFree86 Server, broke. We are in the process of importing a current release of Xorg. New X11 packages will be provided as soon as the port will be completed.
  * ARM USB
      * Dynamic plugin/unplugin of devices on a USB hub is flaky.
